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

2.检查docker版本

[root@jeven ~]# docker version
Client: Docker Engine - Community
 Version:           20.10.21
 API version:       1.41
 Go version:        go1.18.7

  GitCommit:        de40ad0

三、下载wordpress镜像


[root@jeven ~]# docker pull wordpress:php7.3
php7.3: Pulling from library/wordpress

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
