进入mysql容器

操作vi etc/mysql/my.cnf

默认是不安装vi编辑器的，下面安装vi

更新安装包

apt-get update

安装vim

执行这条语句

apt-get install vim

到修改docker容器里面的mysql数据库密码了

启动mysql容器

docker exec -it mysql /bin/bash

编辑配置文件

我这里是没有这个配置文件，直接编辑即可，有的忽略

vi /etc/mysql/conf.d/docker.cnf

加上这4段

mysqld

skip-host-cache

skip-name-resolve

skip-grant-tables 跳过权限认证

保存退出

root@25cf6844e4d5:/# exit

exit

重启mysql容器

我命名的mysql容器名是mysql01，按照自己的名字重启

$root@rzk \~$ # docker restart mysql01

mysql01

进入mysql容器,连接mysql

docker exec -it mysql /bin/bash

$root@rzk \~$ # docker exec -it mysql01 /bin/bash

root@25cf6844e4d5:/# mysql -u root -p

Enter password:

删除权限认证这行

skip-grant-tables 跳过权限认证这一段需要删除，不然后续登录还是会免密码

mysqld

skip-host-cache

skip-name-resolve

skip-grant-tables 跳过权限认证
