LAMP(module)分离于2台主机并安装pma、wp

CentOS 7, lamp (module)；
要求：(1) 三者分离于两台主机；
(2) 一个虚拟主机用于提供phpMyAdmin；另一个虚拟主机用于提供wordpress；
(3) xcache
(4) 为phpMyAdmin提供https虚拟主机；

主机1：192.168.2.110
apache+php
主机2：192.168.2.111
mariadb

一、在主机1上安装httpd、php、php-mysql

[root@localhost ~]# yum install -y httpd php php-mysql

二、创建网站路径目录

[root@localhost ~]# mkdir -pv /www/htdocs/web{1,2}

三、在httpd上配置虚拟主机

[root@localhost ~]# vim /etc/httpd/conf.d/vhosts.conf

<VirtualHost 192.168.2.110:80>
ServerName pma.mylinuxops.com
DocumentRoot /www/htdocs/web1
<Directory /www/htdocs/web1>
Options none
AllowOverRide none
Require all granted
</Directory>
</VirtualHost>

<VirtualHost 192.168.2.110:80>
ServerName wp.mylinuxops.com
DocumentRoot /www/htdocs/web2
<Directory /www/htdocs/web2>
Options none
AllowOverRide none
Require all granted
</Directory>
<VirtualHost>

四、检查配置文件是否有语法错误，启动httpd

[root@localhost ~]# httpd -t
[root@localhost ~]# systemctl start httpd

五、在主机2上安装mariadb，启动mariadb，创建用于pma及wp的用户账号

[root@localhost ~]# yum install -y mariadb-server
[root@localhost ~]# systemctl start mariadb
[root@localhost ~]# mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 2

MariaDB [(none)]> CREATE USER 'wpuser'@'192.168.2.110' IDENTIFIED BY 'magedu';

Bye

六、测试LAMP链接

[root@localhost ~]# vim /www/htdocs/web1/index.php

<?php
$link = $msyql_connect('192.168.2.111','pmauser','magedu');
if ($link)
echo "success";
else
else "failure";
mysql_close();

phpinfo();
?>

七、安装phpMyAdmin
（1）解压phpMyAdmin，并将解压出的文件复制到网站根目录下

[root@localhost ~]# unzip phpMyAdmin-4.0.10.20-all-languages.zip
[root@localhost ~]# cp -a phpMyAdmin-4.0.10.20-all-languages /www/htdocs/web1
[root@localhost web1]# ln -sv /www/htdocs/web1/phpMyAdmin-4.0.10.20-all-languages /www/htdocs/web1/pma
"/www/htdocs/web1/pma" -> "/www/htdocs/web1/phpMyAdmin-4.0.10.20-all-languages"

（2）修改配置文件

[root@localhost web1]# cd pma
[root@localhost pma]# cp config.sample.inc.php config.inc.php
[root@localhost pma]# vim config.inc.php

cfg['Servers'][$i]['host'] = '192.168.2.111'; 将主机指向mysql服务器

(3)安装php-mbstring

[root@localhost web1]# yum install -y php-mbstring

(4)重启httpd服务

[root@localhost web1]# systemctl restart httpd

(5)测试

八、安装wordpress
