docker安装mysql8.0

指定mysql密码(openssl rand -base64 15)

3k0LjRFyWgDBaduquotC

当然mysql也是可以自动生成的.

安装 mysql

安装8.0

cd ~ && mkdir -pv ~/docker/mysql/data80

docker run --name mysql-v80 \
-p 3386:3306  \
-e MYSQL_ROOT_PASSWORD=3k0LjRFyWgDBaduquotC \
-v "$PWD/docker/mysql/data80":/var/lib/mysql  \
-d  mysql:8.0  \
--character-set-server=utf8mb4 \
--collation-server=utf8mb4_unicode_ci

安装5.7(没测试,应该问题不大)

cd ~ && mkdir -pv ~/docker/mysql/data57

docker run --name mysql-v57 \
-p 3376:3306  \
-e MYSQL_ROOT_PASSWORD=3k0LjRFyWgDBaduquotC \
-v "$PWD/docker/mysql/data57":/var/lib/mysql  \
-d  mysql:5.7  \
--character-set-server=utf8mb4 \
--collation-server=utf8mb4_unicode_ci

查看MySQL容器

$ docker ps

进入容器,登陆MySQL

$ docker exec -it mysql-v80 /bin/bash

更改ROOT用户的native_password密码

• 更改加密规则
  ALTER USER 'root'@'localhost' IDENTIFIED BY '3k0LjRFyWgDBaduquotC' PASSWORD EXPIRE NEVER;

• 更新用户密码
  ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '3k0LjRFyWgDBaduquotC';

• 刷新权限
  flush privileges;

采用phpMyAdmin链接

本机地址:
