docker mysql 宿主机访问和docker容器间访问

下载mysql镜像

docker  pull  hub.c.163.com/nce2/mysql:5.6

 创建mysql5.6容器

docker run --name   mymysql  -d -P  hub.c.163.com/nce2/mysql:5.6

 验证容器状态

 通过主机进入mymysql容器

docker  exec   -it   mymysql  bash
//输出
root@4344add2cca7:/#

 登录mysql数据库，查看mysql是否可以正常使用

$ docker exec -it mymysql bash
root@4344add2cca7:/# mysql -uroot -p
Enter password:

对mysql进行远程授权

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> update user set host='%' where user = 'pems';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

 查询容器的ip和容器绑的端口 执行结果如下图

docker-machine  env
docker  ps

 

 宿主机访问mysql连接地址和端口为：192.168.99.100:32768

docker容器之间的访问  --link=mymysql:db  表示把刚才的mymysql容器重新命名为db，然后你就可以在上面的mysqlClient容器中访问到mymysql容器了。

docker  run -it -P --link=mymysql:db   --name=mysqlClient hub.c.163.com/nce2/mysql:5.6 /bin/bash

 在name为mysqlClient中进行数据库访问

root@708f8e6d9d90:/# mysql -h db -upems -ppemsroot
