　　這次實驗準備3臺CentOS7服務器，版本號：CentOS Linux release 7.2.1511。php

搭建Apache服務器

經過 yum -y install httpd 安裝Apache：

訪問正常：

修改配置文件，添加2個虛擬主機，一個提供phpMyAdmin，一個提供wordpress：

[root@happiness ~]# vim /etc/httpd/conf/httpd.conf
#啓用解析，加速httpd服務的啓動
    ServerName localhost:80
#註銷默認主目錄
    #DocumentRoot "/var/www/html"

[root@happiness ~]# vim /etc/httpd/conf.d/vhost.conf
#默認主頁
    DirectoryIndex index.php
#虛擬主機a，後期提供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/$1
        <Directory "/var/www/aaa">
            Options None
            Allowoverride None
            Require all granted
        </Directory>
    </VirtualHost>
#虛擬主機b，後期提供wordpress
    <VirtualHost 192.168.4.119:80>
        ServerName www.bbb.net
        DocumentRoot /var/www/bbb
        ProxyRequests off 
        ProxyPassMatch ^/(.*\.php)$ fcgi://192.168.4.118:9000/var/www/php_bbb/$1
        <Directory "/var/www/bbb">
            Options None
            Allowoverride None
            Require all granted
        </Directory>
    </VirtualHost>

測試2個虛擬主機靜態資源是否可用：

#在虛擬主機a中新建測試頁aaa.html
[root@happiness ~]# vim /var/www/aaa/aaa.html
    <h1>test virtualhost aaa</h1>

#在虛擬主機b中新建測試頁bbb.html
[root@happiness ~]# vim /var/www/bbb/bbb.html
    <h1>test virtualhost bbb</h1>

訪問結果：(實驗中沒搭建dns服務，修改要訪問Apache的主機的hosts文件，添加 192.168.4.119  www.aaa.net 和 192.168.4.119  www.bbb.net，來完成訪問)

搭建php服務器

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

修改php配置文件：

[root@happiness ~]# vim /etc/php-fpm.d/www.conf
#監聽本地能與外部通訊的地址
    listen = 192.168.4.118:9000
#容許哪些主機訪問
    listen.allowed_clients = 192.168.4.119
#確保user、group跟Apache服務器httpd進程的user、group一致
    user = apache
    group = apache
#session目錄不存在，須要手動建立
    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/

#虛擬機a新建php測試頁
[root@happiness ~]# cat /var/www/php_aaa/index.php
    <h1>a</h1>
    <?php
            phpinfo();
    ?>
#虛擬機b新建php測試頁
[root@happiness ~]# cat /var/www/php_bbb/testbbb.php
    <h1>b</h1>
    <?php
        phpinfo();
    ?>

訪問結果：(注意，若是訪問結果出現：File not found相似的提示時，須要關閉php服務器的selinux，臨時關閉經過命令 setenforce Permissive 進行，永久關閉修改配置文件 vim /etc/sysconfig/selinux)

搭建Mariadb服務器

經過 yum -y install mariadb-server 安裝mariadb：

建立mariadb用戶訪問權限：

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;

分別在虛擬機a和b中創建測試頁，看可否成功鏈接mariadb服務器：

[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.";
    ?>

訪問結果：

搭建phpMyAdmin和WordPress

分別從官網下載 phpMyAdmin 和 WordPress 源碼包，分別解壓於對應的虛擬機主目錄下：(此時最新的 phpMyAdmin-4.8.1版本僅支持 PHP 5.5 to 7.2 and MySQL 5.5，而實驗中PHP版本爲5.4，故下載了 phpMyAdmin-4.4.15.10版本)

搭建phpMyAdmin：

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

#修改完配置後複製一整份 phpmyadmin文件到Apache服務器
[root@happiness ~]# scp -r /var/www/php_aaa/phpmyadmin/ root@192.168.4.119:/var/www/aaa/

訪問結果：

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');

#修改完配置後複製一整份wordpress到Apache服務器：
[root@happiness ~]# scp -r /var/www/php_bbb/wordpress root@192.168.4.119:/var/www/bbb/

訪問結果：

藉助php-xcache加速訪問

沒安裝php-xcache進行的壓力測試：

在php服務器上經過 yum -y install php-cache 安裝cache：

systemctl reload php-fpm.service，並進行壓力測試，能夠看到訪問速度有了很大提高：

修改xcache配置文件，修改緩存大小爲100M，再進行壓力測試，能夠看到訪問速度略有提升：

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