　　此次实验准备3台CentOS7服务器，版本号：CentOS Linux release 7.2.1511。

搭建Apache服务器

通过 yum -y install httpd 安装Apache：

CentOS 7部署LAMP+xcache （php-fpm模式）

访问正常：

CentOS 7部署LAMP+xcache （php-fpm模式）

修改配置文件，添加2个虚拟主机，一个提供phpMyAdmin，一个提供wordpress：

[root@happiness ~]# vim /etc/httpd/conf/httpd.conf
#启用解析，加速httpd服务的启动
    ServerName localhost:80
#注销默认主目录
    #DocumentRoot "/var/www/html"

[root@happiness ~]# vim /etc/httpd/conf.d/vhost.conf
#默认主页
    DirectoryIndex index.php
#虚拟主机a，后期提供phpMyAdmin
    <VirtualHost 192.168.4.119:80>
        ServerName www.aaa.net
        DocumentRoot /var/www/aaa
        ProxyRequests off 
        ProxyPassMatch ^/(.*\.php)$ fcgi://192.168.4.118:9000/var/www/php_aaa/$1
        <Directory "/var/www/aaa">
            Options None
            Allowoverride None
            Require all granted
        </Directory>
    </VirtualHost>
#虚拟主机b，后期提供wordpress
    <VirtualHost 192.168.4.119:80>
        ServerName www.bbb.net
        DocumentRoot /var/www/bbb
        ProxyRequests off 
        ProxyPassMatch ^/(.*\.php)$ fcgi://192.168.4.118:9000/var/www/php_bbb/$1
        <Directory "/var/www/bbb">
            Options None
            Allowoverride None
            Require all granted
        </Directory>
    </VirtualHost>

测试2个虚拟主机静态资源是否可用：

#在虚拟主机a中新建测试页aaa.html
[root@happiness ~]# vim /var/www/aaa/aaa.html
    <h1>test virtualhost aaa</h1>

#在虚拟主机b中新建测试页bbb.html
[root@happiness ~]# vim /var/www/bbb/bbb.html
    <h1>test virtualhost bbb</h1>

访问结果：(实验中没搭建dns服务，修改要访问Apache的主机的hosts文件，添加 192.168.4.119  www.aaa.net 和 192.168.4.119  www.bbb.net，来完成访问)

搭建php服务器

通过 yum -y install php-fpm php-mysql php-mbstring 搭建php：

CentOS 7部署LAMP+xcache （php-fpm模式）

修改php配置文件：

[root@happiness ~]# vim /etc/php-fpm.d/www.conf
#监听本地能与外部通信的地址
    listen = 192.168.4.118:9000
#允许哪些主机访问
    listen.allowed_clients = 192.168.4.119
#确保user、group跟Apache服务器httpd进程的user、group一致
    user = apache
    group = apache
#session目录不存在，需要手动创建
    php_value[session.save_path] = /var/lib/php/session

[root@happiness ~]# mkdir /var/lib/php/session
[root@happiness ~]# chown apache:apache /var/lib/php/session
[root@happiness ~]# ll -hd /var/lib/php/session/
    drwxr-xr-x. 2 apache apache 4.0K Jun 21 10:28 /var/lib/php/session/

#虚拟机a新建php测试页
[root@happiness ~]# cat /var/www/php_aaa/index.php
    <h1>a</h1>
    <?php
            phpinfo();
    ?>
#虚拟机b新建php测试页
[root@happiness ~]# cat /var/www/php_bbb/testbbb.php
    <h1>b</h1>
    <?php
        phpinfo();
    ?>

访问结果：(注意，如果访问结果出现：File not found类似的提示时，需要关闭php服务器的selinux，临时关闭通过命令 setenforce Permissive 进行，永久关闭修改配置文件 vim /etc/sysconfig/selinux)

搭建Mariadb服务器

通过 yum -y install mariadb-server 安装mariadb：

CentOS 7部署LAMP+xcache （php-fpm模式）

创建mariadb用户访问权限：

MariaDB [(none)]> CREATE USER 'wpuser'@'192.168.4.118' IDENTIFIED BY 'wppasswd';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON wordpressdb.* TO 'wpuser'@'192.168.4.118';
MariaDB [(none)]> CREATE USER 'pmauser'@'192.168.4.118' IDENTIFIED BY 'pmapasswd';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON pmadb.* TO 'pmauser'@'192.168.4.118';
MariaDB [(none)]> FULSH PRIVILEGES;
MariaDB [(none)]> CREATE DATABASE wordpressdb DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
MariaDB [(none)]> CREATE DATABASE pmadb DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

分别在虚拟机a和b中建立测试页，看能否成功连接mariadb服务器：

[root@happiness ~]# cat /var/www/php_aaa/mysql_conn.php
    <h1>aaa</h1>
    <?php
        $conn = mysql_connect('192.168.4.117','pmauser','pmapasswd');
        if($conn)
            echo "aaa connects successfully";
        else
            echo "aaa fails to connect.";
    ?>
[root@happiness ~]# cat /var/www/php_bbb/mysql_conn.php
    <h1>bbb</h1>
    <?php
        $conn = mysql_connect('192.168.4.117','wpuser','wppasswd');
        if($conn)
            echo "bbb connects successfully.";
        else
            echo "bbb fails to connect.";
    ?>

访问结果：

搭建phpMyAdmin和WordPress

分别从官网下载 phpMyAdmin 和 WordPress 源码包，分别解压于对应的虚拟机主目录下：(此时最新的 phpMyAdmin-4.8.1版本仅支持 PHP 5.5 to 7.2 and MySQL 5.5，而实验中PHP版本为5.4，故下载了 phpMyAdmin-4.4.15.10版本)

CentOS 7部署LAMP+xcache （php-fpm模式）

搭建phpMyAdmin：

#修改phpMyAdmin配置文件
[root@happiness ~]# vim /var/www/php_aaa/phpmyadmin/libraries/config.default.php
#可通过 openssl rand -base64 32 随机字符串
　　$cfg['blowfish_secret'] = 'w14hLCZeyOtg4+9izK9O3oW8BLjTpJVAzF1GCAtJ7U4=';
　　$cfg['Servers'][$i]['host'] = '192.168.4.117';
　　$cfg['Servers'][$i]['user'] = 'pmauser';
　　$cfg['Servers'][$i]['password'] = 'pmapasswd';

#修改完配置后复制一整份 phpmyadmin文件到Apache服务器
[root@happiness ~]# scp -r /var/www/php_aaa/phpmyadmin/ root@192.168.4.119:/var/www/aaa/

访问结果：

搭建WordPress：

#修改WordPress配置文件
[root@happiness ~]# cp /var/www/php_bbb/wordpress/wp-config-sample.php /var/www/php_bbb/wordpress/wp-config.php
[root@happiness ~]# vim /var/www/php_bbb/wordpress/wp-config.php
　　define('DB_NAME', 'wordpressdb');
　　define('DB_USER', 'wpuser');
　　define('DB_PASSWORD', 'wppasswd');
　　define('DB_HOST', '192.168.4.117');

#修改完配置后复制一整份wordpress到Apache服务器：
[root@happiness ~]# scp -r wordpress root@192.168.4.119:/var/www/bbb

访问结果：

借助php-xcache加速访问

没安装php-xcache进行的压力测试：

在php服务器上通过 yum -y install php-cache 安装cache：

systemctl reload php-fpm.service，并进行压力测试，可以看到访问速度有了很大提升：

修改xcache配置文件，修改缓存大小为100M，再进行压力测试，可以看到访问速度略有提高：

[root@happiness ~]# vim /etc/php.d/xcache.ini
    xcache.size  =  100M
