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

- 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
