docker中创建MySQL及在外部使用Navicat连接

docker中创建MySQL及在外部使用Navicat连接

 

1:获取MySQL镜像

运行 docker pull mysql

复制代码
[root@MyCentos7-1 ~]# docker pull mysql  
Using default tag: latest  
latest: Pulling from library/mysql  
85b1f47fba49: Pull complete   
5671503d4f93: Pull complete   
3b43b3b913cb: Pull complete   
4fbb803665d0: Pull complete

2:启动MySQL镜像

[root@MyCentos7-1 ~]# docker run --name=mysql -itd -p 3306:3306 -e MYSQL_ROOT_PASSWORD=abcd123 mysql  
eb3dbfb0958f5c856323e4d8da60d43194884ff05d7adac1ec059adb66ac7f7b  

docker run是启动容器的命令;

--name:指定了容器的名称,方便之后进入容器的命令行

-itd:其中,i是交互式操作,t是一个终端,d指的是在后台运行

-p:指在本地生成一个随机端口,用来映射mysql的3306端口

-e:设置环境变量

MYSQL_ROOT_PASSWORD=emc123123:指定了mysql的root密码

mysql:指运行mysql镜像

3:进入MySQL容器

运行  docker exec -it mysql /bin/bash

[root@MyCentos7-1 ~]# docker exec -it mysql /bin/bash
root@my-mysql-v1-nths4:/usr/local/mysql# 

4:进入MySQL

运行  mysql -uroot -p

复制代码
root@my-mysql-v1-nths4:/usr/local/mysql# mysql -uroot -p 
Enter password:

5:进行配置,使外部工具可以连接

为了安全,首先需要设置root帐号的密码

mysql> update user set authentication_string = password('root') where user = 'root';

root的密码改为root。 
接着,由于mysql中root执行绑定在了localhost,因此需要对root进行授权,代码如下,

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

最后,使用navitecat测试mysql连接,如下,
