CentOS 7系统之 lamp (php-fpm)详解

  安装要求：

(1) 三者分离于三台主机

(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

    1)安装配置httpd

    [[email protected] ~]# yum install httpd -y

[[email protected] ~]# vim /etc/httpd/conf/httpd.conf

#DocumentRoot "/var/www/html"  //注释web默认访问路径

[[email protected] ~]# mkdir /apps/vhosts/b.net -pv //创建虚拟主机wordpress访问页面

[[email protected] ~]# mkdir /apps/vhosts/c.org -pv //创建虚拟主机phpMyAdmin访问页面

    2）基于虚拟主机配置

[[email protected] ~]# vim /etc/httpd/conf.d/vhosts.conf //创建并配置虚拟主机的配置文件

  2、192.168.1.104安装配置 php-fpm ，php-mysql

   1)安装配置php-fpm

[[email protected] ~]# rpm -q php   //确保没有装载php包

package php is not installed

      [[email protected] ~]# yum install php-fpm php-mysql php-mbstring -y

[[email protected] ~]# vim /etc/php-fpm.d/www.conf

listen = 192.168.1.104:9000  //修改php服务器监听地址

listen.allowed_clients = 192.168.1.103  //监听的httpd服务器地址

[[email protected] ~]# mkdir /var/lib/php/session  //创建session目录

[[email protected] ~]# chown apache.apache /var/lib/php/session

[[email protected] ~]# ls -ld /var/lib/php/session

drwxr-xr-x 2 apache apache 6 Jun  2 22:53 /var/lib/php/session

[[email protected] ~]# systemctl start php-fpm.service

2) 创建httpd服务器连接php服务器的测试页

[[email protected] ~]# mkdir /apps/vhosts/b.net -pv

[[email protected] ~]# mkdir /apps/vhosts/c.org -pv

[[email protected] ~]# vim /apps/vhosts/b.net/index.php  //虚拟主机www.b.net主机测试页

[[email protected] ~]# vim /apps/vhosts/c.org/index.php  //虚拟主机www.c.org主机测试页

3）windows物理机添加虚拟主机的解析

   4）windows浏览器进行验证httpd服务器与php服务器的连接

    通过访问浏览器，证明httpd服务器与php服务器的连接是正常的。

 3、192.168.1.105主机安装配置mariadb

1）安装mariadb服务器

[[email protected] ~]# yum install mariadb mariadb-server -y

[[email protected] ~]# vim /etc/my.cnf

skip_name_resolve=ON  //在[mysqld]下添加

[[email protected] ~]# systemctl start mariadb.service

[[email protected] ~]# mysql

 2）创建和授权wordpress和phpMyAdmin用户

MariaDB [(none)]> CREATE DATABASE wpdb; //创建wordpress数据

MariaDB [(none)]> GRANT ALL ON wpdb.* TO [email protected]‘192.168.%.%‘ IDENTIFIED BY ‘wppass‘;  //授权wordpress用户

MariaDB [(none)]> FLUSH PRIVILEGES;

MariaDB [(none)]> CREATE DATABASE pma;  //创建phpMyAdmin数据库

Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> GRANT ALL ON pma.* TO [email protected]‘192.168.%.%‘ IDENTIFIED BY ‘pmapass‘;

Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.00 sec)

3）php主机上创建php和mysql的测试页

[[email protected] ~]# vim /apps/vhosts/b.net/index.php

[[email protected] ~]# vim /apps/vhosts/c.org/index.php

 4）windows浏览器进行验证php服务器与mysql服务器的连接

    至此，httpd服务器、php服务器和mariadb服务器三者之间证明可以正常通信。

4、php主机上安装phpMyAdmin

    1）下载解压phpMyAdmin

    [[email protected] vhosts]# cd  /apps/vhosts/c.org

[[email protected] c.org]# ls

phpMyAdmin-4.4.14.1-all-languages.zip  //下载phpMyAdmin压缩包（https://www.phpmyadmin.net/downloads/）

[[email protected] c.org]# unzip phpMyAdmin-4.4.14.1-all-languages.zip

    [[email protected] c.org]# mv phpMyAdmin-4.4.14.1-all-languages pma

[[email protected] c.org]# cd pma

[[email protected] pma]# mv config.sample.inc.php config.inc.php

   2）配置phpMyAdmin

[[email protected] pma]# openssl rand -base64 15 //生成一段随机数

Q6UQjkqqkH758gITfS45

[[email protected] pma]# vim config.inc.php //编辑配置文件

[[email protected] c.org]# scp -r pma [email protected]:/apps/vhosts/c.org/

// 此时需要把php主机的pma文件放到httpd主机的页面访问路径下

3)httpd主机

[[email protected] ~]# httpd -t  //测试语法

Syntax OK

[[email protected] ~]# systemctl restart httpd.service

4）windows浏览器访问  www.c.org/pma

 5、下载安装配置wordpress

1）下载解压wordpress

[[email protected] conf.d]# cd /apps/vhosts/b.net/

[[email protected] b.net]# ls  //下载wordpress压缩包（下载地址：https://wordpress.org/download/ ）

wordpress-4.3.1-zh_CN.zip

[[email protected] b.net]# unzip wordpress-4.3.1-zh_CN.zip

[[email protected] b.net]# cd wordpress/

[[email protected] wordpress]# mv wp-config-sample.php wp-config.php

    [[email protected] wordpress]# vim wp-config.php

[[email protected]localhost b.net]# scp -r wordpress [email protected]:/apps/vhosts/b.net/   //此时需要把php主机的wordpress文件放到httpd主机的页面访问路径下

2）httpd主机

[[email protected] ~]# httpd -t  //测试语法

Syntax OK

[[email protected] ~]# systemctl restart httpd.service

3）windows浏览器访问 www.b.net/wordpress

6、php服务器安装xcache(配置好CentOS 7的epel源)

1）未装xcache之前，压力测试  http://www.b.net/index.php

[[email protected] ~]# ab -c 100 -n 1000 http://www.b.net/index.php

2)安装xcache

[[email protected] ~]# yum install php-xcache -y

[[email protected] ~]# systemctl restart php-fpm.service

    3）进行压力测试

[[email protected] ~]# ab -c 100 -n 1000 http://www.b.net/index.php

通过安装xcache，发现压力测试效果还是有提升的，我这里只是测试了几次，平时压力测试需要多次测试进行比较。
