2、linux安装docker

• 查看linux内核版本

[root@VM_0_5_centos ~]# uname -r
3.10.0-514.26.2.el7.x86_64

确保版本在3.10以上。如果版本比较低，可以用yum update进行升级

• 安装docker
  yum install docker
• 启动docker
  systemctl start docker
• 设置docker开机启动
  systemctl enable docker
• 关闭docker
  systemctl stop docker
• 启动后查看docker版本来检测是否安装成功
  docker version
• 在docker仓库中查找mysql
  docker search mysql
  结果如下：

[root@VM_0_5_centos ~]# docker search mysql

也可以通过https://hub.docker.com/查找mysql镜像文件

• 从仓库拉取mysql镜像
  docker pull mysql:5.7.21
  冒号后面可以指定版本号，通过网页可以查看官方提供的版本号。
• 查看本机拥有的docker镜像
  docker images
• 删除本机docker镜像
  docker rmi 镜像id
• 运行docker的mysql镜像
  docker run --name mysql-5 -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 mysql:5.7.21
  命令解释：

--name mysql-5:用来自定义容器名字
-d            :表示后台运行
-p 3306:3306  :指定端口，前面的为linux端口，后面的为容器中的端口
-e MYSQL_ROOT_PASSWORD=123456    :用来指定mysqlROOT用户秘密，不指定启动会报错。
mysql:5.7.21    :安装的镜像，就是之前拉取的镜像，需要指定版本不然会到仓库拉取最新版mysql再安装

• 查看安装的容器
  docker ps -a
• 查看正在运行的容器
  docker ps
• 删除容器
  docker rm 容器id
• 启动容器
  docker start 容器id
• 停止容器
  docker stop 容器id
