Ubuntu14.04源碼編譯安裝php7.0和mysql5.6

在阿里雲Ubuntu14.04找不到php7版本的apt安裝包，因此，只能利用源碼來安裝，中間遇到很多坑，在和mysql、Nginx配置時又出現了問題，因此，這裏記錄下來。

1、apt安裝mysql

一、獲取包

一、以前系統安裝了mysql5.5版本，這裏咱們直接卸載,若是以前沒安裝過的能夠跳過該步驟。

# 首先刪除mysql:
sudo apt-get remove mysql-*
# 而後清理殘留的數據
dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P

二、更新包：

apt update

三、查找可安裝的mysql版本

apt-cache search mysql

打印：

...
mysql-server-5.6 - MySQL database server binaries and system database setup
mysql-server-core-5.6 - MySQL database server binaries
mysql-source-5.5 - MySQL source
mysql-source-5.6 - MySQL source
mysql-testsuite - MySQL testsuite
mysql-testsuite-5.5 - MySQL testsuite
mysql-testsuite-5.6 - MySQL 5.6 testsuite

能夠看到咱們的包資源有 mysql-server-5.6 版本。

四、安裝

apt-get install mysql-server-5.6

在安裝的過程當中會須要輸入數據庫密碼，直接輸入便可。

五、檢查mysql是否運行
安裝成功後，使用以下命令查看是否正常運行：

sudo service mysql status

能夠看到mysql已經安裝成功在運行了：

root@iZ:/tmp# sudo service mysql status
mysql start/running, process 848

二、修改配置

六、更改配置
先進入到mysql服務：

#用戶名爲root,密碼假設是123456
mysql -uroot -p123456

更改root訪問的IP權限,不然外網鏈接會被拒絕的。

> use mysql;
> update user set host='%' where user = 'root' and host = '::1'

七、修改MySQL監聽IP

默認狀況下MySQL監聽的是127.0.0.1，也就是本機，因此只有本機可以鏈接上，所以須要將MySQL改爲監聽遠程主機IP或者全部IP。

打開配置文件 /etc/mysql/my.cnf, 找到 bind-address，若是監聽固定遠程IP，則改爲遠程主機IP，若監聽全部IP，則改爲0.0.0.0或者註釋bind-address，咱們這裏直接註釋掉，修改完成後重啓。

#bind-address = 127.0.0.1

重啓mysql

service mysql restart

八、完整的 my.cnf 配置內容：
/etc/mysql/my.cnf

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.
[client]
port        = 3306
socket        = /var/run/mysqld/mysqld.sock

# Here is entries for some specific programs
# The following values assume you have at least 32M ram

# This was formally known as [safe_mysqld]. Both versions are currently parsed.
[mysqld_safe]
socket        = /var/run/mysqld/mysqld.sock
nice        = 0

[mysqld]

#
key_buffer        = 16M
max_allowed_packet    = 16M
thread_stack        = 192K

# Be aware that this log type is a performance killer.
# As of 5.1 you can enable the log at runtime!

#general_log             = 1
#
# Error log - should be very few entries.

#
# Here you can see queries with especially long duration

#
# The following can be used as easy to replay backup logs or for replication.
# note: if you are setting up a replication slave, see README.Debian about
#       other settings you may need to change.
#server-id        = 1
#log_bin            = /var/log/mysql/mysql-bin.log
expire_logs_days    = 10
max_binlog_size         = 100M
innodb_large_prefix = ON
innodb_file_format = BARRACUDA
max_connections = 10000
#binlog_do_db        = include_database_name
#binlog_ignore_db    = include_database_name
#
# * InnoDB
#
# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
# Read the manual for more InnoDB related options. There are many!
#
# * Security Features
#
# Read the manual, too, if you want chroot!
# chroot = /var/lib/mysql/
#
# For generating SSL certificates I recommend the OpenSSL GUI "tinyca".
#
# ssl-ca=/etc/mysql/cacert.pem
# ssl-cert=/etc/mysql/server-cert.pem
# ssl-key=/etc/mysql/server-key.pem

#
# * IMPORTANT: Additional settings that can override those from this file!
#   The files must end with '.cnf', otherwise they'll be ignored.
#
!includedir /etc/mysql/conf.d/

能夠看到，咱們新增了幾個參數到該配置文件：

#5.6兼容5.7出現的mb4索引超過限制問題
innodb_large_prefix = ON
innodb_file_format = BARRACUDA
# 最大鏈接數10000，默認數很小
max_connections = 10000

好了到目前爲止，咱們已經使用apt成功安裝了mysql5.6。

2、源碼編譯安裝php7.0

一、下載源碼

源碼包咱們放在/var/software目錄下：

root@i:/var/software# wget http://am1.php.net/distributions/php-7.0.0.tar.gz

二、解壓安裝

一、解壓

cd /var/software
tar -zxvf php-7.0.0.tar.gz
cd php-7.0.0

二、編譯

root@i:/var/software/php7.0# ./configure --prefix=/usr/local/php7.0 --with-config-file-path=/usr/local/php7.0 --enable-mbstring --enable-ftp --with-gd  --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-pear --enable-sockets --enable-zip --enable-fpm --enable-xml --enable-sockets --with-gd --with-zlib --with-iconv --enable-zip --enable-pcntl --enable-cli --with-openssl --with-curl

--prefix表示php安裝到哪一個路徑，若是不寫系統會默認放到一個路徑，咱們也安裝php必須用的擴展pdo_mysql,openssl,curl等等。

咱們將 php7 安裝到 /usr/local/php7.0 目錄下。

三、編譯安裝：

make && make install

四、測試：
咱們安裝的目錄在：/usr/local/php7.0,該目錄下有這幾個文件夾。

drwxr-xr-x 2 root root  4096 Nov 28 23:22 bin
drwxr-xr-x 3 root root  4096 Nov 29 09:40 etc
drwxr-xr-x 3 root root  4096 Nov 28 23:17 include
drwxr-xr-x 3 root root  4096 Nov 28 23:17 lib
drwxr-xr-x 4 root root  4096 Nov 28 23:17 php
drwxr-xr-x 2 root root  4096 Nov 28 23:22 sbin
drwxr-xr-x 4 root root  4096 Nov 28 23:17 var

進入到安裝目錄後，而後經過命令./bin/php -m查看擴展：

# cd /usr/local/php7.0
# ./bin/php -m
[PHP Modules]
Core
ctype
date
dom
fileinfo
filter
hash
iconv
json
libxml
pcre
PDO

三、簡化PHP執行命令

咱們能夠看到，若是要執行php腳本，須要根據php完整路徑來執行/usr/local/php7.0/bin/php -m,這樣會很繁瑣，很是麻煩，若是設置一個別名，後邊直接跟一個腳本就很是簡單，好比這樣：php -m，是否是很是簡潔？

修改執行命令須要將執行的命令添加到配置文件 /root/.bashrc中：

vim /root/.bashrc

# 新增php快捷命令
alias php=/usr/local/php7.0/bin/php

從新加載：

source /root/.bashrc

這樣，咱們就能夠直接使用 php 來執行命令了，即查看php版本：

root@i:/usr/local/php7.0# php -v
PHP 7.0.0 (cli) (built: Nov 28 2019 23:16:55) ( NTS )
Copyright (c) 1997-2015 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2015 Zend Technologies

四、php-fpm配置

爲php-fpm命令創建軟連接，加入到環境變量中

ln -s /usr/local/php7.0/sbin/php-fpm /usr/local/sbin/php-fpm

複製php配置文件目錄下的 php-fpm.conf.default，並重命名爲 php-fpm.conf

cp /usr/local/php7.0/etc/php-fpm.conf.default  /usr/local/php7.0/etc/php-fpm.conf

編輯 php-fpm.d/www.conf，設置 php-fpm 模塊使用 www-data 用戶和 www-data 用戶組的身份運行,監聽者也是www-data。

user=www-data
group = www-data

listen.owner = www-data
listen.group = www-data
listen.mode = 0660

listen=/usr/local/php7.0/var/run/php7.0-fpm.sock

這裏有一個大坑，搞了很久好整明白，默認是監聽 listen=127.0.0.1:9000，在Nginx fastcgi_pass 咱們使用的是socket監聽的，因此，這裏須要改成socket監聽模式：

listen=/usr/local/php7.0/var/run/php7.0-fpm.sock

這個路徑 /usr/local/php7.0/ 是咱們的php安裝路徑，若是使用其餘路徑，會找不到 php7.0-fpm.sock 文件的，因此，這裏必須是你的PHP安裝路徑，另外，php7.0-fpm.sock 默認是不存在的，在運行時纔會產生。

root@i:/usr/local/php7.0/var/run# ls -l
total 4
-rw-r--r-- 1 root     root     4 Nov 29 11:40 php-fpm.pid
srw-rw---- 1 www-data www-data 0 Nov 29 11:40 php7.0-fpm.sock

www.conf完整配置：
路徑：/usr/local/php7.0/etc/php-fpm.d/www.conf

; Start a new pool named 'www'.
; the variable $pool can we used in any directive and will be replaced by the
; pool name ('www' here)
[www]

; Per pool prefix
; It only applies on the following directives:
; - 'access.log'
; - 'slowlog'
; - 'listen' (unixsocket)
; - 'chroot'
; - 'chdir'
; - 'php_values'
; - 'php_admin_values'
; When not set, the global prefix (or /usr/local/php7.0) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
user=www-data
group = www-data

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
;                            a specific port;
;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses
;                            (IPv6 and IPv4-mapped) on a specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
;listen = 127.0.0.1:9000
listen=/usr/local/php7.0/var/run/php7.0-fpm.sock
; Set listen(2) backlog.
; Default Value: 511 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 511

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
;                 mode is set to 0660
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
; When POSIX Access Control Lists are supported you can set them using
; these options, value is a comma separated list of user/group names.
; When set, listen.owner and listen.group are ignored
;listen.acl_users =
;listen.acl_groups =

; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1

; Specify the nice(2) priority to apply to the pool processes (only if set)
; The value can vary from -19 (highest priority) to 20 (lower priority)
; Note: - It will only work if the FPM master process is launched as root
;       - The pool processes will inherit the master process priority
;         unless it specified otherwise
; Default Value: no set
; process.priority = -19

; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;
;   dynamic - the number of child processes are set dynamically based on the
;             following directives. With this process management, there will be
;             always at least 1 children.
;             pm.max_children      - the maximum number of children that can
;                                    be alive at the same time.
;             pm.start_servers     - the number of children created on startup.
;             pm.min_spare_servers - the minimum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is less than this
;                                    number then some children will be created.
;             pm.max_spare_servers - the maximum number of children in 'idle'
;                                    state (waiting to process). If the number
;                                    of 'idle' processes is greater than this
;                                    number then some children will be killed.
;  ondemand - no children are created at startup. Children will be forked when
;             new requests will connect. The following parameter are used:
;             pm.max_children           - the maximum number of children that
;                                         can be alive at the same time.
;             pm.process_idle_timeout   - The number of seconds after which
;                                         an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic

; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don't
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 15

; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 2

; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 1

; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 3

; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to 'ondemand'
; Default Value: 10s
;pm.process_idle_timeout = 10s;

; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
;pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. It shows the following informations:
;   pool                 - the name of the pool;
;   process manager      - static, dynamic or ondemand;
;   start time           - the date and time FPM has started;
;   start since          - number of seconds since FPM has started;
;   accepted conn        - the number of request accepted by the pool;
;   listen queue         - the number of request in the queue of pending
;                          connections (see backlog in listen(2));
;   max listen queue     - the maximum number of requests in the queue
;                          of pending connections since FPM has started;
;   listen queue len     - the size of the socket queue of pending connections;
;   idle processes       - the number of idle processes;
;   active processes     - the number of active processes;

;   max active processes - the maximum number of active processes since FPM
;                          has started;
;   max children reached - number of times, the process limit has been reached,
;                          when pm tries to start more children (works only for
;                          pm 'dynamic' and 'ondemand');
; Value are updated in real time.
; Example output:
;   pool:                 www
;   process manager:      static
;   start time:           01/Jul/2011:17:53:49 +0200

;   total processes:      15
;   max active processes: 12
;   max children reached: 0
;
; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the query string will return the corresponding
; output syntax. Example:
;   http://www.foo.bar/status
;   http://www.foo.bar/status?json
;   http://www.foo.bar/status?html
;   http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
;   http://www.foo.bar/status?full
;   http://www.foo.bar/status?json&full
;   http://www.foo.bar/status?html&full
;   http://www.foo.bar/status?xml&full
; The Full status returns for each process:
;   pid                  - the PID of the process;
;   state                - the state of the process (Idle, Running, ...);
;   start time           - the date and time the process has started;
;   start since          - the number of seconds since the process has started;

;   request duration     - the duration in µs of the requests;
;   request method       - the request method (GET, POST, ...);
;   request URI          - the request URI with the query string;
;   content length       - the content length of the request (only with POST);
;   user                 - the user (PHP_AUTH_USER) (or '-' if not set);
;   script               - the main script called (or '-' if not set);
;   last request cpu     - the %cpu the last request consumed
;                          it's always 0 if the process is not in Idle state
;                          because CPU calculation is done when the request
;                          processing has terminated;
;   last request memory  - the max amount of memory the last request consumed
;                          it's always 0 if the process is not in Idle state
;                          because memory calculation is done when the request
;                          processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.
; Example output:

;       may conflict with a real PHP file.
; Default Value: not set
;pm.status_path = /status

; The ping URI to call the monitoring page of FPM. If this value is not set, no
; URI will be recognized as a ping page. This could be used to test from outside
; that FPM is alive and responding, or to
; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
;       anything, but it may not be a good idea to use the .php extension or it
;       may conflict with a real PHP file.
; Default Value: not set

;  %t: server time the request was received
;      it can accept a strftime(3) format:
;      %d/%b/%Y:%H:%M:%S %z (default)
;      The strftime(3) format must be encapsuled in a %{<strftime_format>}t tag
;      e.g. for a ISO8601 formatted timestring, use: %{%Y-%m-%dT%H:%M:%S%z}t
;  %T: time the log has been written (the request has finished)
;      it can accept a strftime(3) format:
;      %d/%b/%Y:%H:%M:%S %z (default)
;      The strftime(3) format must be encapsuled in a %{<strftime_format>}t tag

; Note: slowlog is mandatory if request_slowlog_timeout is set
;slowlog = log/$pool.log.slow

; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option
; does not stop script execution for some reason. A value of '0' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_terminate_timeout = 0

; Set open file descriptor rlimit.
; Default Value: system defined value
;rlimit_files = 1024

; Set max core size rlimit.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
;       possible. However, all PHP paths will be relative to the chroot
;       (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =

; Chdir to this directory at the start.
; Note: relative path can be used.
; Default Value: current directory or / when chroot
;chdir = /var/www

; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
;catch_workers_output = yes

; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this
; pool configuration are added.
; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; exectute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5 .php7

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call 'ini_set'.
;   php_admin_value/php_admin_flag - these directives won't be overwritten by
;                                     PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr/local/php7.0)

; Default Value: nothing is defined by default except the values in php.ini and
;                specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm-php.www.log
;php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M

五、php.ini文件

咱們能夠看到 /usr/local/php7.0 安裝的目錄裏邊沒有 php.ini 配置文件，這就須要咱們把源碼包的 php.ini 拷貝到咱們的安裝目錄。

拷貝：

# 進入源碼包
cd /var/software/php7.0
cp php.ini-development /usr/local/php7.0/etc

修改文件名 php.ini-development 爲 php.ini：

cd /usr/local/php7.0/etc
mv php.ini-development php.ini

這裏還有一個坑，就是有時候咱們改了php.ini文件後沒有生效，這樣的問題怎麼排查呢？

能夠用下邊這個命令php -i | grep php.ini來看：

php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/php7.0

咱們能夠看到，最終的執行路徑在 /usr/local/php7.0 下面，正常咱們是放在 /usr/local/php7.0/etc 下邊，編譯以後會放在 /usr/local/php7.0 下，因此咱們把etc下邊的移到 php7.0安裝目錄下面便可：

root@i:/usr/local/php7.0# mv ./etc/php.ini ./

而後再查看：

root@i:/usr/local/php7.0# php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/php7.0
Loaded Configuration File => /usr/local/php7.0/php.ini

修改php.ini 默認配置：

#避免暴露php調用mysql的錯誤信息
display_errors = Off
#開啓錯誤日誌
log_errors = On
#錯誤日誌路徑
error_log = /var/log/php7.0/php_errors.log

#設置PHP的時區
date.timezone = PRC

六、安裝擴展

若是擴展在源碼包裏邊有，咱們直接在源碼包裏邊進行編譯安裝便可，如 openssl 擴展包：

源碼擴展包：

/var/software/php-7.0.0/ext

root@iZ94j7ehy5oZ:/var/software/php-7.0.0/ext# ls -l
total 316
drwxr-xr-x  4 1000 1000  4096 Dec  1  2015 bcmath

drwxr-xr-x  4 1000 1000  4096 Nov 28 23:12 mysqli
drwxr-xr-x  3 1000 1000  4096 Nov 28 23:15 mysqlnd
drwxr-xr-x  3 1000 1000  4096 Dec  1  2015 oci8

drwxr-xr-x  8 1000 1000  4096 Nov 28 23:12 pdo_mysql

若是咱們要安裝的擴展在源碼安裝包不存在，則須要在網上下載，而後進行安裝，這裏以 phpredis擴展爲例：

下載：

wget https://github.com/phpredis/phpredis/archive/5.0.0.tar.gz

更更名字

mv 5.0.0.tar.gz phpredis-5.0.0.tar.gz

解壓：

tar -zvx phpredis-5.0.0.tar.gz

進入解壓目錄生成配置文件：

/var/software/# cd phpredis-5.0.0
/var/software/phpredis-5.0.0# /usr/local/php7.0/bin/phpize

./configure --with-php-config=/usr/local/php7.0/bin/php-config

make && make install

編譯成功後，會在/usr/local/php7.0/lib/php/extensions/no-debug-non-zts-20151012/ 目錄後，看到新生成的擴展redis.so。

而後在 php.ini 添加擴展

extension_dir="/usr/local/php7.0/lib/php/extensions/no-debug-non-zts-20151012/"
extension=redis.so

咱們擴展安裝OK。

3、Nginx和php-fpm使用

配置Nginx和php-fpm用Sock套接字鏈接，這裏注意路徑。
nginx 的配置：

cat /etc/nginx/vhost/blog.conf

完整配置：

server {
        listen 80;

        root /var/www/myblog/public;
        index index.php  index.html index.htm;

        # Make site accessible from http://localhost/
        server_name digtime.cn www.digtime.cn;

        # ssl-20160924
        # rewrite ^/(.*) https://myblog.cn/$1 permanent;
        # add_header Access-Control-Allow-Origin *;        

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                # handle 405 error
                # if ($request_method = 'OPTIONS') { 
                #  add_header Access-Control-Allow-Origin *; 
                # add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,OPTIONS;
                # return 204; 
                #}
                
                try_files $uri $uri/ /index.php?$query_string;
                # Uncomment to enable naxsi on this location
                # include /etc/nginx/naxsi.rules
                # 405 error
        }


        location ~ \.php$ {
               try_files $uri /index.php =404;

               fastcgi_split_path_info ^(.+\.php)(/.+)$;

               fastcgi_pass unix:/usr/local/php7.0/var/run/php7.0-fpm.sock;

               fastcgi_index index.php;

               fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

               include fastcgi_params;
         }
}

注意：fastcgi_pass 這裏使用和咱們php-fpm 監聽的那裏的路徑同樣：

fastcgi_pass unix:/usr/local/php7.0/var/run/php7.0-fpm.sock;

填完這些坑，咱們的環境纔算搭建成功。
