1、簡介php

　　LAMP:linux+apache+mysql（這裏用mariadb）+php（perl，python）html

　　LAMMP:memcached緩存的python

　　CGI:Common Gateway Interface通用網關接口，說白了就是個簡化的httpd協議mysql

　　httpd+php有三種模式linux

　　　　modules 動態模塊模式，最簡單最容易配置的方式，httpd啓動時會加載模塊，加載時將對應的模塊激活，php-cgi也就啓動了，不少人認爲動態編譯模塊時在須要的時候隨時加載調用，不須要的時候就中止，其實動態編譯的模塊實際上和靜態編譯模塊同樣，動態加載的模塊被加載時就被加入到激活鏈表中，不管使用不使用，它都已經運行在httpd的內部web

　　　　cgi 模式， 不多使用這個模式，httpd接受到一個動態請求就fork一個cgi進程，cgi進程返回結果給httpd進程後自我銷燬sql

　　　　fastcgi（fpm），php-fpm模式，使用php-fpm管理php-cgi，httpd不在控制php-cgi進程的啓動，能夠將php-fpm獨立運行在非web服務器上，實現動靜分離。數據庫

　　最簡單就是模塊的方式加入apache，fastcgi模式的php-cgi,是由php-fpm提供服務管理，它會根據配置文件啓動必定數量的cgi進程，其默認監聽端口爲9000，該服務正常工做須要配置文件，因此fastcgi模式的php有兩個配置文件，一個php的配置文件，一個是php-fpm的配置文件。apache

　　模塊化安裝php，不推薦在apache2.x中使用先出啊MPM（worker和event），而是使用prefork模式的mpm，由於linux系統線程設計並非那麼完美，因此，若是php和apache在同一個主機上（cgi或模塊化方式安裝php的時候），建議httpd使用prefork模型，而不一樣主機，建議php設計在fastcgi的工做模式，而windows平臺無需考慮這個問題，由於windows系統是真正意義上的多線程系統。vim

　　本文yum安裝LAMP得步驟，其中php使用得是frefork模型的，還有單獨一臺主機實現反代動態資源php-fpm管理方式。

　　一、官方資源下載地址：http://archive.apache.org/dist/

　　二、實驗環境

主機	IP地址	用途	備註
web1	192.168.216.199	web服務器	虛擬機　　centos7
web2	192.168.216.198	Mysql服務器	虛擬機　　centos7
客戶端			物理機　　win10
web4			虛擬機　　centos7，壓測
web3	192.168.216.232	php-fpm	虛擬機　　centos7，實現反向動態代理

　　三、測試環境關閉selinux，firewall

　　關閉selinux

　　vim /etc/selinux/config

 1 # This file controls the state of SELinux on the system.
 2 # SELINUX= can take one of these three values:
 3 #     enforcing - SELinux security policy is enforced.
 4 #     permissive - SELinux prints warnings instead of enforcing.
 5 #     disabled - No SELinux policy is loaded.
 6 SELINUX=disabled  7 # SELINUXTYPE= can take one of three two values:
 8 #     targeted - Targeted processes are protected,
 9 #     minimum - Modification of targeted policy. Only selected processes are protected.
10 #     mls - Multi Level Security protection.
11 SELINUXTYPE=targeted

　　關閉防火牆

　　systemctl stop firewalld

　　systemctl disable firewalld

　　init 6

　　四、LAMP架構圖

2、配置安裝LAMP

　　一、解決依賴

　　　　yum -y install @"Development Tools" libxml2-devel mariadb-devel bzip2-devel

　　二、安裝安裝關鍵軟件包，httpd與php

　　　　yum install httpd httpd-devel php php-mysql

　　　　啓動服務

　　　　systemctl start httpd

　　　　檢查監聽端口

　　　　　　80端口監聽

3 NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
4 SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
5
6 In order to log into MariaDB to secure it, we'll need the current
7 password for the root user. If you've just installed MariaDB, and
8 you haven't set the root password yet, the password will be blank,
9 so you should just press enter here.
10
11 Enter current password for root (enter for none): <-初次使用直接回車便可 12 OK, successfully used password, moving on...
13
14 Setting the root password ensures that nobody can log into the MariaDB
15 root user without the proper authorisation.
16
17 Set root password? [Y/n] y <-輸入y,設置root密碼 18 New password: <-設置root得密碼 19 Re-enter new password: <-重複密碼 20 Password updated successfully!
21 Reloading privilege tables..
22 ... Success!
23
24
25 By default, a MariaDB installation has an anonymous user, allowing anyone
26 to log into MariaDB without having to have a user account created for
27 them. This is intended only for testing, and to make the installation
28 go a bit smoother. You should remove them before moving into a
29 production environment.
30
31 Remove anonymous users? [Y/n] y <-是否刪除匿名用戶，建議刪除 32 ... Success!
33
34 Normally, root should only be allowed to connect from 'localhost'. This
35 ensures that someone cannot guess at the root password from the network.
36
37 Disallow root login remotely? [Y/n] y <-是否禁止root遠程登錄，建議禁止,我這裏測試選擇N不由止 38 ... Success!
39
40 By default, MariaDB comes with a database named 'test' that anyone can
41 access. This is also intended only for testing, and should be removed
42 before moving into a production environment.
43
44 Remove test database and access to it? [Y/n] y <-是否刪除test數據庫，建議刪除 45 - Dropping test database...
46 ... Success!
47 - Removing privileges on test database...
48 ... Success!
49
50 Reloading the privilege tables will ensure that all changes made so far
51 will take effect immediately.
52
53 Reload privilege tables now? [Y/n] y <-是否從新加載權限表，y 54 ... Success!
55
56 Cleaning up...
57
58 All done! If you've completed all of the above steps, your MariaDB
59 installation should now be secure.

61 Thanks for using MariaDB!

　　4）、php和數據庫關聯並測試

　　在web1上vim /var/www/html/index.php

 1 [root@web1 html]# cat index.php 
 2 vim index.php 
 3 <?php
 4 $conn=mysql_connect('192.168.216.202','root','你的root密碼');
 5 if ($conn)
 6 echo "Success...";
 7 else
 8 echo "Failure!!!";
 9 ?>
10 [root@web1 html]#

　　咱們來訪問一下

　　php

　　　檢查一下php默認使用哪一種模型模塊

 1 [root@web1 conf.d]# pwd
 2 /etc/httpd/conf.d
 3 [root@web1 conf.d]# cat php.conf 
 4 #
 5 # Cause the PHP interpreter to handle files with a .php extension.
 6 #
 7 <FilesMatch \.php$>
 8     SetHandler application/x-httpd-php
 9 </FilesMatch>
10 
11 #
12 # Allow php to handle Multiviews
13 #
14 AddType text/html .php
15 
16 #
17 # Add index.php to the list of files that will be served as directory
18 # indexes.
19 #
20 DirectoryIndex index.php
21 
22 #
23 # Uncomment the following lines to allow PHP to pretty-print .phps
24 # files as PHP source code:
25 #
26 #<FilesMatch \.phps$>
27 #    SetHandler application/x-httpd-php-source
28 #</FilesMatch>
29 
30 #
31 # Apache specific PHP configuration options
32 # those can be override in each configured vhost
33 #
34 php_value session.save_handler "files"
35 php_value session.save_path    "/var/lib/php/session"
36 [root@web1 conf.d]#

　　好像看不到，接下來，看到是用的prefork MPM

 1 [root@web1 conf.d]# cat /etc/httpd/conf.modules.d/00-mpm.conf 
 2 # Select the MPM module which should be used by uncommenting exactly
 3 # one of the following LoadModule lines:
 4 
 5 # prefork MPM: Implements a non-threaded, pre-forking web server
 6 # See: http://httpd.apache.org/docs/2.4/mod/prefork.html
 7 LoadModule mpm_prefork_module modules/mod_mpm_prefork.so  8 
 9 # worker MPM: Multi-Processing Module implementing a hybrid
10 # multi-threaded multi-process web server
11 # See: http://httpd.apache.org/docs/2.4/mod/worker.html
12 #
13 #LoadModule mpm_worker_module modules/mod_mpm_worker.so 14 
15 # event MPM: A variant of the worker MPM with the goal of consuming
16 # threads only for connections with active processing
17 # See: http://httpd.apache.org/docs/2.4/mod/event.html
18 #
19 #LoadModule mpm_event_module modules/mod_mpm_event.so

3、怎麼使用fast-cgi那

　　　　如今利用web3作php-fpm，作反代

　　一、web3

　　　　yum install php-fpm php-mysql php-mbstring php-mcrypt php-zlib

　　　　php-mbstring:多字節字符支持；

　　　　php-mcrypt:整合libmcrpt至php加密傳輸

　　　　php-zlib：壓縮傳輸

　　　　rpm -ql php-fpm

　　　　查看一下路徑

 1 [root@web3 ~]# rpm -ql php-fpm
 2 /etc/logrotate.d/php-fpm
 3 /etc/php-fpm.conf
 4 /etc/php-fpm.d
 5 /etc/php-fpm.d/www.conf
 6 /etc/sysconfig/php-fpm
 7 /run/php-fpm
 8 /usr/lib/systemd/system/php-fpm.service
 9 /usr/lib/tmpfiles.d/php-fpm.conf
10 /usr/sbin/php-fpm
11 /usr/share/doc/php-fpm-5.4.16
12 /usr/share/doc/php-fpm-5.4.16/fpm_LICENSE
13 /usr/share/doc/php-fpm-5.4.16/php-fpm.conf.default
14 /usr/share/fpm
15 /usr/share/fpm/status.html
16 /usr/share/man/man8/php-fpm.8.gz
17 /var/log/php-fpm
18 [root@web3 ~]#

　　二、修改配置文件

　　　　vim /etc/php-fpm.d/www.conf

 1 [root@web3 ~]# vim /etc/php-fpm.d/www.conf 
 2 
 3 ; Start a new pool named 'www'.
 4 [www]
 5 
 6 ; The address on which to accept FastCGI requests.
 7 ; Valid syntaxes are:
 8 ;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on
 9 ;                            a specific port;
10 ;   'port'                 - to listen on a TCP socket to all addresses on a
11 ;                            specific port;
12 ;   '/path/to/unix/socket' - to listen on a unix socket.
13 ; Note: This value is mandatory.
14 listen = 192.168.216.232:9000 #監聽在哪臺主機的9000端口，232即php-fpm服務器
15 
16 ; Set listen(2) backlog. A value of '-1' means unlimited.
17 ; Default Value: -1
18 ;listen.backlog = -1
19 
20 ; List of ipv4 addresses of FastCGI clients which are allowed to connect.
21 ; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
22 ; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
23 ; must be separated by a comma. If this value is left blank, connections will be
24 ; accepted from any ip address.
25 ; Default Value: any
26 listen.allowed_clients = 192.168.216.199 #容許哪臺主機，199爲httpd，即web服務器
27 
28 ; Set permissions for unix socket, if one is used. In Linux, read/write
29 ; permissions must be set in order to allow connections from a web server. Many
30 ; BSD-derived systems allow connections regardless of permissions.
31 ; Default Values: user and group are set as the running user
32 ;                 mode is set to 0666
33 ;listen.owner = nobody
34 ;listen.group = nobody
35 ;listen.mode = 0666
36 
37 ; Unix user/group of processes
38 ; Note: The user is mandatory. If the group is not set, the default user's group
39 ;       will be used.
40 ; RPM: apache Choosed to be able to access some dir as httpd
41 user = apache
42 ; RPM: Keep a group allowed to write in log dir.
43 group = apache
44 
45 ; Choose how the process manager will control the number of child processes.
46 ; Possible Values:
47 ;   static  - a fixed number (pm.max_children) of child processes;
48 ;   dynamic - the number of child processes are set dynamically based on the
49 ;             following directives:
50 ;             pm.max_children      - the maximum number of children that can
51 ;                                    be alive at the same time.
52 ;             pm.start_servers     - the number of children created on startup.
53 ;             pm.min_spare_servers - the minimum number of children in 'idle'
54 ;                                    state (waiting to process). If the number
55 ;                                    of 'idle' processes is less than this
56 ;                                    number then some children will be created.
57 ;             pm.max_spare_servers - the maximum number of children in 'idle'
58 ;                                    state (waiting to process). If the number
59 ;                                    of 'idle' processes is greater than this
60 ;                                    number then some children will be killed.
61 ; Note: This value is mandatory.
62 pm = dynamic　　　　　　　　#動態請求是prefork模型

　　　　啓動服務

　　　　systemctl start php-fpm.service

　　　　建立目錄

　　　　mkdir -pv /data/web/

　　　　建立index.php，讀取info就能夠了

　　　　vim /data/web/index.php

1 [root@web3 ~]# cat /data/www/index.php 
2 <?php
3 phpinfo();
4 ?>
5 [root@web3 ~]#

　　三、web1，web服務器上建個虛擬主機

 1 [root@web1 conf.d]# cat /etc/httpd/conf.d/fcgi.conf 
 2 DirectoryIndex index.php
 3 <VirtualHost *:80>
 4 DocumentRoot "/data/web/fcgi"
 5 ProxyRequests off
 6 ProxyPassMatch ^/(.*\.php)$ fcgi://192.168.216.232:9000/data/www/fcgi/$1
 7 <Directory "data/web/fcgi">
 8 Options FollowSymlinks
 9 AllowOverride None
10 Require all granted
11 </Directory>
12 CustomLog logs/www_access_log combined
13 ErrorLog logs/www_error_log
14 </VirtualHost>
15 [root@web1 conf.d]#

　　　　測試語法

　　　　httpd -t

[root@web1 conf.modules.d]# httpd -t
AH00112: Warning: DocumentRoot [/data/web/fcgi] does not exist　　　　#忽略這個錯誤
Syntax OK
[root@web1 conf.modules.d]# !sys
systemctl restart httpd

　　　　重啓服務

　　　　systemctl restart httpd

　　測試網頁

3、測試

　　一、壓測

　　web4作壓力測試
