CentOS 7系统之 lamp (php-fpm)详解

Posted 2020-07-20

  

  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

    

IP	系统	软件
192.168.1.103	CentOS 7	httpd
192.168.1.104	CentOS 7	php-fpm,php-mysql,，xcache
192.168.1.105	CentOS 7	mariadb

---

  1、192.168.1.103 安装配置httpd

    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] 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。
