lnmp环境搭建

注：在此文件中配置所需要的容器  docker-compose.yml  ，并执行：docker-compose up -d

docker exec -it wechat_web_1 bash或docker-compose exec php bash  进入docker中查看原始php目录

1、安装Docker，命令：yum install docker-ce   默认安装最新版本

yum install docker-ce

安装Docker，命令：yum install docker-ce-版本号，我选的是17.12.1.ce，如下

[root@localhost ~]# yum install docker-ce-17.12.1.ce

2、安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的

$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2

3、启动并加入开机启动

$ sudo systemctl start docker
$ sudo systemctl enable docker

4、验证安装是否成功(有client和service两部分表示docker安装启动都成功了)

$ docker version
