恢复原有wordpress推荐使用宝塔面板，本文介绍配置新的wordpress站点。
yum update -y yum install docker -y yum list | grep docker docker -v vim /etc/docker/daemon.json { "registry-mirrors": ["https://hub-mirror.c.163.com","https://registry.aliyuncs.com","https://registry.docker-cn.com"]} systemctl start docker.service systemctl enable docker 1.从github下载docker-compose二进制文件安装
curl -L "https://github.com/docker/compose/releases/download/1.29.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose docker-compose -v 默认网络不支持指派固定IP，使用固定IP则需要自定义网络。
docker pull wordpress:latest docker pull mysql:5.7 docker run -d --privileged=true --name mysql_57 -v /data/mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -p 33306:3306 mysql:5.7 docker run -d --name wp -e WORDPRESS_DB_HOST=mysql -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=123456 -e WORDPRESS_DB_NAME=wp -p 8000:80 --link mysql_57:mysql wordpress firewall-cmd --zone=public --add-port=8000/tcp --permanentfirewall-cmd --reload http://127.0.0.1:8000 注意8888是宝塔面板的默认端口
mysql参考配置 ： https://hub.docker.com/_/mysql

firewall-cmd --zone=public --add-port=8000/tcp --permanent firewall-cmd --reload 在WordPress 根目录下的wp-config.php 文件大概79行下有下面一段代码：
