1、自定义网络
docker network create lnmp
2、创建Mysql容器
docker run -d --name lnmp_mysql --net lnmp --mount src=mysql-vol,dst=/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 --character-set-server=utf8
3、创建PHP容器
docker run -d --name lnmp_php --net lnmp --mount src=wwwroot,dst=/wwwroot php:v1
4、创建Nginx容器
docker run -d --name lnmp_nginx --net lnmp -p 88:80 --mount src=wwwroot,dst=/wwwroot nginx:v1
5、以wordpress博客为例
