docker安装WordPress
1、下载php-apache镜像web服务器中执行以下操作:
docker pull php:7.2-apache
下载完成使用docker images 命令查看一下在的镜像

2、创建生成mysql、httpd-php容器的脚本
web中：
vim docker_web.sh
#!/bin/bash
docker run --name httpd-php-p 80:80 \ -v /data/docker/httpd/conf:/etc/apache2/sites-enabled \ -v /data/docker/www:/var/www/html \ -v /data/docker/httpd/logs:/var/log/apache2 \ -d php:7.2-apache
mysql中：
vim docker_mysql.sh
#!/bin/bash
docker run --name mysql-p 3306:3306 \ -v /data/docker/mysql/data:/var/lib/mysql \ -v /data/docker/mysql/conf:/etc/mysql/conf.d \ -v /data/docker/mysql/logs:/logs \
-e MYSQL_ROOT_PASSWORD=test123456 \ #设置mysql的root密码
-d mysql:latest --character-set-server=utf8 #使用utf8编码
###注意脚本里有注释可能会报错 docker: invalid reference format###
3、启动mysql、httpd-php容器
web中：
sh docker_web.sh

mysql中：
sh docker_mysql.sh

4、测试web服务器
在命令行输入
echo "" > /data/docker/www/index.php
打开浏览器访问web服务器的ip地址

5、修改mysql的密码加密方式
修改mysql的密码加密方式为mysql_native_password
vim /data/docker/mysql/conf/docker_mysql.cnf
default-authentication-plugin=mysql_native_password
如果不修改加密方式的话，低版本的mysql客户端登陆时会报错
6、数据库操作
登陆mysql容器，创建、配置wordpress数据库
docker exec -it mysql /bin/bash mysql -uroot -ptest123456
mysql> create database wordpress;
mysql> create user wps@localhost identified by '123456';
mysql> grant all privileges on wordpress. to wps@localhost;
mysql> create user wps@192.168.8.126 identified by '123456';
mysql> grant all privileges on wordpress. to wps@192.168.8.126;
mysql> alter user wps@192.168.8.126 identified with mysql_native_password by '123456';
mysql> create user wps@192.168.8.127 identified by '123456';
mysql> grant all privileges on wordpress.* to wps@192.168.8.127;
mysql> alter user wps@192.168.8.127 identified with mysql_native_password
by '123456';
mysql> exit
7、连接测试
在web1和web2中：
PHP5.0开始就不推荐使用mysql_connect()函数了，而到了php7.0则直接废弃了该函数，替代的函数是mysqli_connect()
进入到mysql容器里安装mysqli扩展
docker exec -it httpd-php /bin/bash
apt-get update
apt-get install libpng-dev
cd /usr/local/bin/
./docker-php-ext-install gd mysqli
./docker-php-ext-enable gd mysqli
exit
docker restart httpd-php
编写一个测试连接mysql的php
vim /data/docker/www/con.php
打开浏览器输入192.168.8.126/con.php

8、下载wordpress博客系统并配置
wget https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz
tar -zxvf wordpress-4.9.4-zh_CN.tar.gz -C /data/docker/www/
浏览器访问http://192.168.8.126/wordpress
https://s1.运维网.com/images/blog/201901/09/45027968724bf8e596b9f9f05428695c.png
如图填写，注意主机写安装了mysql服务的虚拟机ip

9、验证wordpress数据库
mysql主机的容器里连接数据库：
mysql -u root -ptest123456
https://s1.运维网.com/images/blog/201901/09/6b36e9c23db98cd4892adf1ec8b33040.png
显示数据库
https://s1.运维网.com/images/blog/201901/09/72c06fb49df052e4dc28afa5d358b4bf.png
使用wordpress数据库
https://s1.运维网.com/images/blog/201901/09/1dd7a1facbe355255f67e9a4bb63dffb.png
显示wordpress数据库里的表
https://s1.运维网.com/images/blog/201901/09/bf96b490cf516dfc24d16e17193c5719.png
选择wp_users表里的所有内容
https://s1.运维网.com/images/blog/201901/09/db0f7163c729d20fe7d26bf6b05cc2fd.png
可以看到已经有了lxc这个账户。
10、查看博客
浏览器访问http://192.168.8.126/wordpress
