先來說講爲啥子，要寫這篇文章

由於服務器操做系統，軟件版本，以及需求，都千奇百怪。網上有不少教程每一種都不同！並且按照上面傻瓜式複製粘貼操做完成安裝的也在少數(本人用了不少可是沒有一個傻瓜操做成功的) 基本上都是有些經驗的遇到安裝錯誤以後自行解決了！，因此我這面綜合寫一個文章（其實就是閒的）
閒話很少說，開始第一波操做php

1. 磁盤建立快照（小白推薦）【此項非必須項，也可直接從2開始】

毋庸置疑，在服務器進行一系列環境搭建以前，作好建立一個快照（就是系統的某一個時間點的全部備份，就跟照片同樣，時間定格某一個畫面），防止你的系統被你安裝的亂七八糟的！到時候很差刪，直接回滾磁盤來的方便！html

雲服務器( 栗子：阿里雲）
建立辦法：控制檯->雲服務器->選中你的實例->本實例的磁盤->建立快照 (這裏若是你還找不到的話，聽個人話放棄IT吧孩子)
使用辦法：控制檯->雲服務器->選中你的實例->本實例的快照->回滾磁盤（這時候你的全部配置什麼的環境啊，也都回滾了）
mysql
獨立服務器
獨立服務器，就是指你本身有的硬件服務器（通俗來說就是，你能看到的實體的服務器）
這裏不作推薦，由於若是你會搭建快照軟件的話，這篇文章對你提高也不大！散了吧
若是你不會可是想學習一下的話，想了解一下的話能夠看一下下面的連接
《10種linux下磁盤快照方式恢復系統》

2. 安裝nginx

安裝nginx 以前先肯定好本身的服務器操做系統對應相對應的操做系統來作！linux

contos（本人用的是新的CentOS 7.4 64，其實我的感受版本什麼的安裝程序差異不大）nginx
- 1）用root用戶找到你的目錄文件夾（本人推薦用root用戶進行安裝，不知道的 'cd ~'）c++
- 2）開始安裝依賴(yum不知道是什麼命令的，本身百度科普一下yum rpm 編譯安裝)web
  
  gcc:nginx編譯依賴gcc環境
  yum install -y gcc-c++
  
  pcre:(Perl Compatible Regular Expressions)是一個Perl庫，包括 perl 兼容的正則表達式庫。nginx的http模塊使用pcre來解析正則表達式.
  yum install -y pcre pcre-devel
  
  zlib：該庫提供了不少種壓縮和解壓縮的方式，nginx使用zlib對http包的內容進行gzip。
  yum install -y zlib zlib-devel
  
  openssl:一個強大的安全套接字層密碼庫，囊括主要的密碼算法、經常使用的密鑰和證書封裝管理功能及SSL協議，並提供豐富的應用程序供測試或其它目的使用。nginx不只支持http協議，還支持https（即在ssl協議上傳輸http）.
  yum install -y openssl openssl-devel
- 3)下載安裝nginx（我這裏是1.12的版本，你們能夠自行選擇）正則表達式
  
  wget http://nginx.org/download/nginx-1.12.0.tar.gz 下載安裝包
  
  tar -zxvf nginx-1.12.0.tar.gz 解壓安裝包
  
  cd nginx-1.12.0 找到解壓
  
  接下來是重點的部分
  注：安裝以前須要手動建立上面指定的nginx文件夾，即 /var/temp、/var/temp/nginx、/var/run/nginx/文件夾，不然啓動時報錯（若是不知道怎麼新建文件夾《Linux 學習之建立、刪除文件和文件夾命令》，或者用ftp建立也行)
  (爲何要這麼作，由於這個是在網絡上面比較好的一個安裝目錄，要否則就用yum安裝了，安裝以後別說nginx配置文件在哪？網站根目錄在哪？若是不知道這些配置文件的用途推薦大家看《Nginx編譯參數大全 configure參數中文詳解》)
  ./configure \ --prefix=/usr/local/nginx \ --pid-path=/var/run/nginx/nginx.pid \ --lock-path=/var/lock/nginx.lock \ --error-log-path=/var/log/nginx/error.log \ --http-log-path=/var/log/nginx/access.log \ --with-http_gzip_static_module \ --http-client-body-temp-path=/var/temp/nginx/client \ --http-proxy-temp-path=/var/temp/nginx/proxy \ --http-fastcgi-temp-path=/var/temp/nginx/fastcgi \ --http-uwsgi-temp-path=/var/temp/nginx/uwsgi \ --http-scgi-temp-path=/var/temp/nginx/scgi 配置命令（一塊兒複製）
  
  make && make install 編譯而且編譯安裝
  
  這就基本上能夠了使用了
  
  cd /usr/local/nginx/sbin/ 找到執行文件地方
  ./nginx 啓用nginx
  若報錯： [emerg] open() "/var/run/nginx/nginx.pid" failed (2: No such file or directory)
  須要查看下是否是在 /var/run 文件夾下不存在 nginx 文件夾，不存在則新建
  ps -ef | grep nginx 咱們能夠看一下這個是否啓動成功了
  
  也就是證實你安裝成功了
  啓動成功後訪問你的ip或者域名就能看到
  
  想要中止就要
  cd /usr/local/nginx/sbin && ./nginx -s stop 強行中止
  cd /usr/local/nginx/sbin && ./nginx -s quit 完整中止(建議使用)
  cd /usr/local/nginx/sbin && ./nginx -s quit && ./nginx 重啓
  cd /usr/local/nginx/sbin && ./nginx -s reload 從新加載配置
  可是這樣很麻煩，通常咱們都會用shell作成服務，若是你嫌麻煩那麼能夠看一下如何封裝成服務
  service nginx restart 重啓
  service nginx stop 中止
  service nginx start 啓動
  這樣是否是很帥，請看後續教程《小白系列：如何將軟件裝成service》

寫累了，未完待續---2018-08-11算法

3. 安裝PHP

開始安裝php了sql

contos（本人用的是新的CentOS 7.4 64，其實我的感受版本什麼的安裝程序差異不大）
- 1）回到到你的目錄文件夾（不知道的 'cd ~'）
- 2）開始安裝一些經常使用的php庫
  
  依次執行如下命令（經常使用的庫，若是有什麼要用的沒有安裝的，等安裝完php後本身再獨立安裝也能夠）
  yum -y install libmcrypt-devel mhash-devel libxslt-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel
- 3)下載並安裝php（我這裏是7.1.11的版本，你們能夠自行選擇）
  
  wget http://cn2.php.net/distributions/php-7.1.11.tar.gz 下載php官方安裝包(速度仍是蠻快的說)
  
  tar -zxvf php-7.1.11.tar.gz 解壓安裝包
  
  cd php-7.1.11 找到解壓
  
  開始配置編譯參數
  ./configure \ --prefix=/usr/local/php7 \ --with-config-file-path=/usr/local/php7/etc \ --enable-fpm \ --with-mcrypt \ --enable-mbstring \ --enable-pdo \ --with-curl \ --disable-debug \ --disable-rpath \ --enable-inline-optimization \ --with-bz2 \ --with-zlib \ --enable-sockets \ --enable-sysvsem \ --enable-sysvshm \ --enable-pcntl \ --enable-mbregex \ --with-mhash \ --enable-zip \ --with-pcre-regex \ --with-mysqli \ --with-gd \ --with-jpeg-dir \ --with-freetype-dir \ --enable-calendar 配置命令（一塊兒複製）
  
  make && make install 編譯而且編譯安裝(那這個時間就比較長了，我先去吃點東西~)
  
  直接啓動會報錯，先依次執行下面命令，將默認的配置文件變成真正的配置文件
  cp /root/php-7.1.11/php.ini-production /usr/local/php7/etc/php.ini
  
  cd /usr/local/php7/etc
  
  cp php-fpm.conf.default php-fpm.conf
  
  cd /usr/local/php7/etc/php-fpm.d
  
  cp www.conf.default www.conf
  
  須要查看下是否是在 /var/run 文件夾下不存在 php7文件夾，不存在則新建
  使用vim命令對 php-fpm.conf的內容進行以下修改
  cd /usr/local/php7/etc 找到配置文件夾
  vim php-fpm.conf 打開後輸入i進入編輯模式
  pid = /run/php7/php-fpm.pid
  （大概在17行左右，記住把前面的 ; 去掉,至於爲何在/run/php7/這，由於本人喜歡和nginx保持一致）
  以後按 esc，在以後按 shift+: 輸入 wq回車（這文檔編輯就不在這教你們了）
  
  cd /usr/local/php7/sbin && ./php-fpm 啓動
  而後查看一下是否啓動成功
  
  圖上就表示啓動成功了
  
  關閉比較麻煩
  kill 進程id (注意關閉以前確認這個ID 必定要，別關錯了，【僞裝這裏有一個苦笑的表情】)
  
  那麼php就安裝完了若是有人問到，爲何我 php -v啥的很差使呢，這個跟windows同樣,須要放在環境變量裏面，這個和上個面的nginx均可以封裝成系統的service，如下mysql也是同樣！這樣啓動，和重啓，關閉啥的就很簡單了！請看後續教程《小白系列：如何將軟件裝成service》

該午休了，未完待續---2018-09-11

午休結束了，如今開始繼續---2018-09-18

4.好了接下來就是 nginx 和 php 怎麼一塊兒工做了

the first one
都說創建專用的用戶組來運行php和nginx那麼好咱們去創建一個最多見到的www-data
groupadd www-data
useradd www-data -g www-data -s /sbin/nologin -M
而後仍是修改配置文件

the second one
找到nginx的站點目錄 /usr/local/nginx/html/
新建一個文件叫phpinfo.php內容是 <?php phpinfo();?>
(此時若是要經過http://你的ip地址/phpinfo.php，他會默認給你下載下來這個php文件)

the thrid one
找到nginx的配置文件夾/usr/local/nginx/conf中的nginx.conf
編輯一下將其中的

第二行的#user nobody;
改爲user www-data;

第九行的#pid logs/nginx.pid;
改爲 pid /var/run/nginx/nginx.pid;

將中間的
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}

改爲這種
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

the fourth one
找到nginx的配置文件夾/usr/local/php7/etc/php-fpm.d中的www.conf
將其中的23行24行
user = nobody
group = nobody
改成
user = www-data
group = www-data

the end
重啓一下php
而後重啓一下nginx
怎麼重啓我上面有寫。這裏就不重複了
你在訪問一下就會發現http://你的ip地址/phpinfo.php 能夠解析了
具體的文件我放在下面，你們能夠對比一下
並且用戶組也都變了

www.conf

; Start a new pool named 'www'.
; the variable $pool can be 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) 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

; 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 = nobody
;listen.group = nobody
;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 = 5

; 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;
;   total processes      - the number of idle + 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
;   start since:          62636
;   accepted conn:        190460
;   listen queue:         0
;   max listen queue:     1
;   listen queue len:     42
;   idle processes:       4
;   active processes:     11
;   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, ...);

;      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

; Default Value: not set
; 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

; 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

; 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
; execute 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[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)

; 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
