The distributed implementation of lamp--install WordPress, phpMyAdmin

Title: Deploy httpd, PHP-FPM, mariadb with three CentOS 7 hosts respectively

First 192.168.10.101--httpd second 192.168.10.102--php-fpm third 192.168.10.103--mariadb

The SELinux and Iptables are closed before starting to facilitate testing.

# iptables-f# Setenforce 0

The configuration starts from the first one.

#安装httpd

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

#配置虚拟主机

#创建资源映射目录

[[email protected] ~]# Mkdir-pv/apps/vhosts/{a.com,b.net}

#注释掉中心主机的文档根路径

#DocumentRoot "/var/www/html"

#检查语法

[[email protected] ~]# Httpd-tsyntax OK

#启动httpd服务进程

[Email protected] ~]# systemctl start Httpd.service:::* [Email protected] ~]# SS-TNL | grep 80LISTEN 0::: +:::*

#创建静态资源文件, as a test

[Email protected] ~]# vim/apps/vhosts/a.com/index.html

#修改hosts文件
# vim/etc/hosts192.168.10.101 www.a.com www.b.net www.c.org

#确保httpd有装载fcgi模块
[Email protected] ~]# Httpd-m | grep fcgi proxy_fcgi_module (shared)

Configure a third host.
#安装数据库
[Email protected] ~]# yum-y install Mariadb-server

#启动起来
[[email protected] ~]# systemctl start mariadb.service[[email protected] ~]# SS-TNL | grep 3306LISTEN 0 *:3306 *:*

#授权用户及创建数据库
[[email protected] ~]# mysqlmariadb [(none)]> GRANT all on wpdb.* to [e-mail protected] ' 192.168.%.% ' identified by ' Wppa SS '; MariaDB [(None)]> FLUSH privileges; MariaDB [(None)]> CREATE DATABASE wpdb;

Configure the second host.
#要安装php-FPM and Php-mysql
[Email protected] ~]# yum-y install PHP-FPM php-mysql

#修改配置文件
[[email protected] ~]# Vim/etc/php-fpm.d/www.conflisten = 192.168.10.102:9000 # listening on the local network interface listen.allowed_clients = 19 2.168.10.101 # allow the first host to connect # other default invariant

#创建资源映射目录
[[email protected] ~]# Mkdir-pv/apps/vhosts/{a.com,b.net}

#写入php连接数据库的测试代码

#启动php-FPM Service Process
[[email protected] ~]# systemctl start php-fpm[[email protected] ~]# SS-TNL | grep 9000LISTEN 0 192.168.10.102:9000 *:*

#安装php-xcache Accelerator
[Email protected] ~]# yum-y install Php-xcache

#测试没有问题之后, you can now start deploying WordPress and phpMyAdmin programs on the second host.
#首先搞定WordPress
#从官网下载WordPress压缩包
[Email protected] ~]# wget https://cn.wordpress.org/wordpress-4.7.4-zh_CN.zip

#下载后解压, and move to the resource map directory path
[Email protected] ~]# unzip Wordpress-4.7.4-zh_cn.zip[[email protected] ~]# mv wordpress/apps/vhosts/a.com

#cd进该目录, and copy the sample configuration file wp-config-sample.php to wp-config.php
[[email protected] ~]# Cd/apps/vhosts/a.com/wordpress/[[email protected] wordpress]# CP wp-config-sample.php wp-config.php

#修改配置文件wp-config.php, the database information that needs to be modified here comes from the database name, user name, and password that you just created on the third host.
[[email protected] wordpress]# VIM wp-config.php//* * MySQL Settings-specific information from the host you are using * *///** the name of the WordPress database */define (' db_name    ', ' wpdb ');    # Modify the database name, use the database you just created on the third host/** MySQL database username */define (' db_user ', ' wpuser ');    # Modify user name/** MySQL database password */define (' Db_password ', ' wppass ');    # Change Password/** mysql host */define (' Db_host ', ' 192.168.10.103 '); # The MySQL host here points to the third host

#至此WordPress就配置完成了, you need to overload the PHP-FPM configuration file
[Email protected] ~]# Systemctl Reload Php-fpm.service

#测试WordPress
#使用浏览器输入URL为http://www.a.com/wordpress

#但是输入http://www.a.com/wordpress is able to access, has ruled out the impact of DirectoryIndex, So how to enable users to access the virtual host www.a.com WordPress directory when automatically return to index.php it?

#问题解决思路: It is possible to create/apps/vhosts/a.com/wordpress on the first host, although the dynamic resources under WordPress are stored on the second PHP-FPM host, while the first httpd host is used to store static resources , but it may still be necessary to have wordpress this empty directory on the first host.
[Email protected] ~]# mkdir/apps/vhosts/a.com/wordpress

#再使用浏览器打开, the URL entered is still http://www.a.com/wordpress

#和刚才一样的解决思路, create the Wp-admin directory under the WordPress directory in the www.a.com site directory on the virtual host on the first host

#至此Wordpress安装并测试成功, then take care of the 2nd virtual host on the first console phpMyAdmin
#在第二台主机上下载phpMyAdmin压缩包
