云原生之使用Docker部署wordpress网站
一、wordpress介绍
WordPress是使用PHP语言开发的博客平台，用户可以在支持PHP和MySQL数据库的服务器上架设属于自己的网站。也可以把 WordPress当作一个内容管理系统（CMS）来使用。
二、检查本地docker环境
1.检查docker状态
[root@jeven ~]# systemctl status docker
● docker.service - Docker Application Container Engine

Status: Downloaded newer image for wordpress:php7.3
docker.io/library/wordpress:php7.3
四、创建数据库
1.创建数据目录
mkdir -p /data/wordpress/{db,data}
2.创建mysql数据库容器
docker run -d --name my_mysql --restart always -e MYSQL_ROOT_PASSWORD=redhat -e MYSQL_DATABASE=db_web -p 3710:3306 mysql:5.7
3.查看mysql容器状态
[root@jeven ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
95cb245317e3 mysql:5.7 "docker-entrypoint.s…" 38 seconds ago Up 37 seconds 33060/tcp, 0.0.0.0:3710->3306/tcp, :::3710->3306/tcp my_mysql
4.远程客户端测试连接数据库
[root@server ~]# mysql -h 192.168.3.166 -P3710 -uroot -predhat

五、部署wordpress
1.创建wordpress容器
docker run -d --name my_wordpress --restart always --link my_mysql -e WORDPRESS_DB_HOST=192.168.3.166:3710 -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=redhat -e WORDPRESS_DB_NAME=db_web -p 8167:80 wordpress:php7.3
2.查看wordpress容器状态
[root@jeven wordpress]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
91696767911c wordpress:php7.3 "docker-entrypoint.s…" 45 seconds ago Up 44 seconds 0.0.0.0:8167->80/tcp, :::8167->80/tcp my_wordpress
95cb245317e3 mysql:5.7 "docker-entrypoint.s…" 4 minutes ago Up 4 minutes 33060/tcp, 0.0.0.0:3710->3306/tcp, :::3710->3306/tcp my_mysql
六、wordpress初始配置
