docker实例之mysql的使用

常用步骤 命令
1:搜索镜像 docker search xxx
2:拉取镜像 docker pull xxx:yy
3:查看镜像 docker image inspect xxx:yy
4:运行容器 docker run xxx:yy
5:停止容器 docker container stop ID
6:删除容器 docker container rm ID

演示:

1:搜索mysql镜像

[root@docker ~]# docker search mysql

......

2:拉取镜像

[root@docker ~]# docker pull mysql:5.7

Status: Downloaded newer image for mysql:5.7
docker.io/library/mysql:5.7
[root@docker ~]# docker image ls -a  
[root@docker ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mysql               5.7                 1e4405fe1ea9        4 days ago          437MB

3:查看镜像信息

[root@docker ~]# docker  image inspect 1e44
...

4:启动一个容器

[root@docker ~]# docker run -p 12345:3306 --name mysql -v /root/mysql/conf:/etc/mysql/conf.d  -v /root/mysql/logs:/logs -v /root/mysqlhttps://img.qb5200.com/download-x/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.7
fc136870a6baf32639f08a5f4c545aaca26815cecc0c26018184b86b36c72531
[root@docker ~]# docker container ls -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                NAMES
fc136870a6ba        mysql:5.7           "docker-entrypoint.s…"   18 seconds ago      Up 12 seconds       33060/tcp, 0.0.0.0:12345->3306/tcp   mysql

#命令说明:
-p[小写]:将主机的 12345端口映射到容器内部端口3306 
--name:设置别名 mysql 
-v /root/mysql/conf:/etc/mysql/conf.d 
-v /root/mysql/logs:/logs
-v /root/mysqlhttps://img.qb5200.com/download-x/data:/var/lib/mysql 
-e MYSQL_ROOT_PASSWORD=123456  #初始化root用户密码
-d mysql:5.7  #后台运行

5:进入容器并使用mysql

[root@docker ~]# docker exec -it fc136870a6ba /bin/bash
root@fc136870a6ba:/#

root@fc136870a6ba:/# mysql -uroot -p
Enter password:     #123456前面设置的

[root@docker ~]# 

mysql练习结束


6:使用win主机上的Navicat for MySQL 连接 虚拟机中运行的mysql容器

1:找到容器运行的主机的IP地址
[root@docker ~]# ifconfig eno16777728 |grep broad  | sed  's/inet//' |sed 's/netmask.*//'
         192.168.1.10 
         
      
2:在win主机中远程连接

数据和刚刚在容器中的生成的一样,成功。
