LAMP架构之httpd+php(module)+mariadb

CentOS 7, lamp(module)；
实现：
(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) 为php提供xcache；
(4) 为phpMyAdmin网站提供https虚拟主机




ON http(172.16.17.7)：

1）安装httpd及php程序包

[root@node1 ~]# yum -y install httpd php php-mysql php-mbstring

2）httpd虚拟主机www.pma.com以及www.wordpress.com，新建/etc/httpd/conf.d/vhosts.conf

<VirtualHost *:80>
ServerName www.pma.com
DocumentRoot "/web/pma/htdocs"
<Directory "/web/pma/htdocs">
Options None
AllowOverride None
Require all granted
</Directory>
</VirtualHost>

<VirtualHost *:80>
ServerName www.wordpress.com
DocumentRoot "/web/wordpress/htdocs"
<Directory "/web/wordpress/htdocs">
Options None
AllowOverride None
Require all granted
</Directory>
</VirtualHost>

3）安装配置PHPmyadmin程序

[root@node1 ~]# mkdir -pv /web/{pma,wordpress}
[root@node1 ~]# unzip phpMyAdmin-4.4.14.1-all-languages.zip -d /web/pma/
[root@node1 ~]# mv /web/pma/phpMyAdmin-4.4.14.1-all-languages/ /web/pma/htdocs
[root@node1 ~]# cd /web/pma/htdocs
[root@node1 htdocs]# cp config.sample.inc.php config.inc.php
[root@node1 htdocs]# openssl rand -base64 20
5Cfn69rDk+6I3Twd4KtgLfT/v5k=
编辑config.inc.php文件，将生成的随机数复制到里面，然后更改数据库连接主机：
$cfg['blowfish_secret'] = '5Cfn69rDk+6I3Twd4KtgLfT/v5k';
$cfg['Servers'][$i]['host'] = '172.16.17.8';

4）安装配置wordpress程序

[root@node1 ~]# unzip wordpress-4.3.1-zh_CN.zip -d /web/wordpress/
[root@node1 ~]# mv /web/wordpress/wordpress/ /web/wordpress/htdocs
[root@node1 ~]# cd /web/wordpress/htdocs
[root@node1 htdocs]# cp wp-config-sample.php wp-config.php
编辑wp-config.php文件，配置数据库连接信息：
define('DB_NAME', 'wpdb');
define('DB_USER', 'wpuser');
define('DB_PASSWORD', 'wppasswd');
define('DB_HOST', '172.16.17.8');

5）启动httpd服务

[root@node1 ~]# httpd -t
Syntax OK
[root@node1 ~]# systemctl start httpd.service

ON mariadb(172.16.17.8)：

1）创建运行mariadb的用户

[root@node2 ~]# groupadd -r mysql
[root@node2 ~]# useradd -r -g mysql mysql

2）创建数据库存放目录

[root@node2 ~]# mkdir -pv /data/mysql
[root@node2 ~]# chown -R mysql.mysql /data/mysql/

3）解压mariadb程序包至/usr/local，并创建mysql软链接

[root@node2 ~]# tar xf mariadb-5.5.46-linux-x86_64.tar.gz -C /usr/local/
[root@node2 ~]# cd /usr/local/
[root@node2 local]# ln -sv mariadb-5.5.46-linux-x86_64/ mysql

4）初始化数据库

[root@node2 local]# chown -R root.mysql mysql/
[root@node2 mysql]# scripts/mysql_install_db --user=mysql --datadir=/data/mysql

5）提供mysql主配置文件并编辑之

[root@node2 mysql]# mkdir /etc/mysql
[root@node2 mysql]# cp support-files/my-medium.cnf /etc/mysql/my.cnf
在my.cnf配置文件中的[mysqld]端添加以下内容：
datadir = /data/mysql         //设置mysql的数据存储目录
innodb_file_per_table = ON    //设置innodb存储引擎独立存储数据库
skip_name_resolve = ON        //禁止mysql进行反解主机名

6）提供mysql服务脚本

[root@node2 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
[root@node2 mysql]# chmod +x /etc/rc.d/init.d/mysqld
[root@node2 mysql]# chkconfig --add mysqld
[root@node2 mysql]# chkconfig mysqld on

7）启动mysqld服务

[root@node2 ~]# service mysqld start

8）创建wpdb库，授权wpuser用户连接

MariaDB [(none)]> CREATE SCHEMA wpdb;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON wpdb.* TO 'wpuser'@'172.16.%.%' IDENTIFIED BY 'wppasswd';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON *.* TO 'root'@'172.16.%.%' IDENTIFIED BY '123qwe!@#';
MariaDB [(none)]> FLUSH PRIVILEGES;

打开浏览器，添加hosts文件解析，访问网站：






















客户端使用ab命令对服务器进行压力测试：

[root@localhost ~]# ab -c 50 -n 500 http://www.pma.com/index.php[/code] href="http://s3.51cto.com/wyfs02/M00/7A/4F/wKioL1anSKTyclESAAA9miJwC88091.png" target=_blank>



ON http(172.16.17.7)：[b]为web服务器编译安装xcache[/b]
1）安装php-devel包及开发工具包组
[root@node1 ~]# yum -y install php-devel
[root@node1 ~]# yum -y groupinstall "Development Tools" "Server Platform Development"
2）解压xcache源码包至/usr/local下
[root@node1 ~]# tar xf xcache-3.2.0.tar.bz2 -C /usr/local/
[root@node1 ~]# mv /usr/local/xcache-3.2.0/ /usr/local/xcache
3）生成configure脚本
[root@node1 xcache]# phpize
4）执行编译安装
[root@node1 xcache]# ./configure --enable-xcache --with-php-config=/usr/bin/php-config
[root@node1 xcache]# make -j 4 && make install
5）复制xcache的ini文件至/etc/php.d目录下

[root@node1 xcache]# cp xcache.ini /etc/php.d/
6）重启httpd服务

[root@node1 ~]# systemctl restart httpd.service


再次在客户端使用ab命令对服务器进行压力测试：
[root@localhost ~]# ab -c 50 -n 500 http://www.pma.com/index.php[/code] href="http://s1.51cto.com/wyfs02/M00/7A/4F/wKioL1anSoqj_5f-AAA9ldG-Ol8493.png" target=_blank>



为PHPMyAdmin网站提供https虚拟主机：
