实验环境：均是CentOS7
httpd：172.16.254.88 2.4.6
PHP：172.16.250.140 5.4.16
mariadb:172.16.250.94 5.5.52
第三方应用程序是：phpMyAdmin
1、先配置httpd主机：
[root@www localhost]#cd /etc/httpd/conf.d/
[root@conf.d localhost]#cat vhost.conf
DirectoryIndex index.php
<VirtualHost 172.16.254.88:80>
ServerName 172.16.254.88
DocumentRoot "/data/www"
ProxyRequests Off #关闭正向代理
ProxyPassMatch ^/(.*\.php)$ fcgi://172.16.250.140:9000/data/www/$1 #表示后缀名为php的动态资源请求的时候转发到ip为172.16.250.140的主机进行处理；
ProxyPassMatch ^/(pmstatus|ping.*)$ fcgi://172.16.250.140:9000/$1 #测试pmstatus和ping的内置功能
<Directory "/data/www">
Options FollowSymLinks
AllowOverride None
Require all granted
</Directory>
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 15
ErrorLog /var/log/httpd/test_error.log
CustomLog /var/log/httpd/test_access.log combined
</VirtualHost>
[root@conf.d localhost]#cd /data/www #网页文件和第三方程序的路径，与PHP服务器上的文件一模一样
[root@www localhost]#ls
index1.php index.php phpMyAdmin-4.0.10.20 pma
[root@www localhost]#ll
total 12
-rw-r--r--. 1 root root 13 Jun 3 20:48 index1.php
-rw-r--r--. 1 root root 261 Jun 3 23:35 index.php
drwxr-xr-x. 9 root root 4096 Jun 3 23:18 phpMyAdmin-4.0.10.20
lrwxrwxrwx. 1 root root 21 Jun 4 00:10 pma -> phpMyAdmin-4.0.10.20/ #程序文件的软连接，方便访问
[root@phpMyAdmin-4.0.10.20 localhost]#pwd
/data/www/phpMyAdmin-4.0.10.20
[root@phpMyAdmin-4.0.10.20 localhost]#cp -av config.sample.inc.php config.inc.php
$cfg['blowfish_secret'] = 'jngkasfnysagfehfcsdkjdfa8b6d'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
##添加一些字符串
$cfg['Servers'][$i]['host'] = '172.16.250.94'; #配成mariadb的地址
[root@www localhost]#pwd
/data/www
[root@www localhost]#cat index.php
<html>
<title>test</title>
<body>
<h2> CentOS7 Text</h2>
<?php
phpinfo();
?>
</body>
</html>
[root@libraries localhost]#pwd
/data/www/phpMyAdmin-4.0.10.20/libraries
* MySQL hostname or IP address
*
* @global string $cfg['Servers'][$i]['host']
*/
$cfg['Servers'][$i]['host'] = '172.16.250.94'; ##修改mariadb的地址
2、PHP主机：
[root@www localhost]#yum install -y php php-fpm php-mysql
[root@www localhost]#cd /etc/php-fpm.d/
[root@php-fpm.d localhost]#cat www.conf
; Start a new pool named 'www'.
[www]
; 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 address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses on a
; specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = 172.16.250.140:9000 #本服务器地址
; Set listen(2) backlog. A value of '-1' means unlimited.
; Default Value: -1
;listen.backlog = -1
pm.status_path = /pmstatus #测试本服务器的进程状态
ping.path = /ping #ping的测试
ping.response = pong #pong的回应，测试服务器的通讯状态
curity 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. This value must be an absolute path.
; Default Value: current directory or / when chroot
chdir = /data/www #第三方程序存放目录和httpd的/data/www中的文件一模一样
; Set session path to a directory owned by process user
php_value[session.save_handler] = files
php_value[session.save_path] = /var/lib/php/session
3、mariadb主机：
[root@~ localhost]#yum -y install mariadb-server
[root@my.cnf.d localhost]#pwd
/etc/my.cnf.d
[root@my.cnf.d localhost]#cat server.cnf
#
# this is only for the mysqld standalone daemon
[mysqld]
skip_name_resolve=ON
innodb_file_per_table=ON
#给用户授权连接，同样的给httpd的用户也要授权
[root@my.cnf.d localhost]#mysql -pEnter password:
