Docker常用安装MYSQL

总体步骤

• 搜索镜像
• 拉取镜像
• 查看镜像
• 启动镜像
• 停止容器
• 移除容器

安装tomcat

• docker hub上面查找tomcat镜像
• 从docker hub上拉取tomcat镜像到本地
• docker images查看是否有拉取到的tomcat
• 使用tomcat镜像创建容器（也叫运行镜像）

安装mysql

docker hub 上面查找musql镜像

[[e-mail] ~]# docker search mysql

从docker hub上（阿里云加速）拉取mysql镜像到本地标签为5.6

[[e-mail] ~]# docker pull mysql:5.6

使用mysql5.6镜像创建容器（也叫运行镜像）

[[e-mail] ~]# docker run -p 12345:3306 --name mysql -v /ghj/mysql/conf:/etc/mysql/conf.d -v /ghj/mysql/logs:/logs -v /ghj/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6

命令说明：
-p 12345：3306：将主机的12345端口映射到docker容器的3306端口。
–name mysql：运行服务器名字
-v /ghj/mysql/conf:/etc/mysql/conf.d：将主机/ghj/mysql目录下的/conf挂载到容器的/etc/mysql/conf.d
-v /ghj/mysql/logs:/logs：将主机/ghj/mysql目录下的logs目录挂载到容器的/logs
-v /ghj/mysql/data:/var/lib/mysql：将主机/ghj/mysql目录下的data目录挂载到容器的/var/lib/mysql
-e MYSQL_ROOT_PASSWORD=123456：初始化root用户的密码
-d mysql:5.6：后台程序运行mysql5.6

启动交互式运行：

[[e-mail] ~]# docker exec -it 5e67a99464d5 /bin/bash
[e-mail]:/# mysql -uroot -p
Enter password: 
输入123456

外部Win10来连接运行在docker上的mysql服务

在可视化工具中添加一条数据，然后我们在去docker中查看

mysql> select * from my_book;
+----+----------+
| id | bookName |
+----+----------+
|  1 | java     |
|  2 | C++      |
