Docker容器化技术（docker-compose示例:部署discuz论坛和wordpress博客，使用adminer管理数据库）

 安装docker-compose

[root@service ~]# systemctl stop firewalld
[root@service ~]# setenforce 0
[root@service ~]# systemctl start docker[root@service ~]# wget https://github.com/docker/compose/releases/download/v2.5.0/docker-compose-linux-x86_64

创建目录

[root@service composetest]# mkdir test
[root@service composetest]# cd test/
[root@service test]# vim docker-compose.yml

编写docker-compose.yml文件
