Docker下安装Mysql57

一、拉取MySQL镜像

[root@localhost ~]# docker pull centos/mysql-57-centos7

Using default tag: latest

latest: Pulling from centos/mysql-57-centos7

d8d02d457314: Pull complete

Status: Downloaded newer image for centos/mysql-57-centos7:latest

docker.io/centos/mysql-57-centos7:latest

过程比较漫长，下载时长取决于网速。有可能失败，可尝试几次。

二、创建容器

[root@localhost ~]# docker run -di --name=tensequare_mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 centos/mysql-57-centos7

e88c265a46d484b35a96d599dc5047494c7a7e5e5cd7aa3a49bc864a88bdb33

-p：代表端口映射，格式为 宿主机映射端口:容器运行端口

-e：代表添加环境变量MYSQL_ROOT_PASSWORD是root用户的登录密码

三、修改密码

1、进入mysql容器。

[root@localhost ~]# docker exec -it tensequare_mysql /bin/bash

bash-4.2$

2、登录mysql。第一次进入不需要密码

bash-4.2$ mysql -u root -p

Enter password:

3、修改密码策略。

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456' PASSWORD EXPIRE NEVER;

Query OK, 0 rows affected (0.00 sec)

mysql> ALTER USER 'root' IDENTIFIED WITH mysql_native_password BY '123456';

Query OK, 0 rows affected (0.00 sec)

四、设置远程访问

使用exit退出docker的mysql，进入到宿主机中，在防火墙中增加端口为3306。命令为

bash-4.2$ exit;

exit

[root@localhost ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent

success

[root@localhost ~]# firewall-cmd --reload

success
