linux系统 docker安装mysql 后 改了配置 无法启动mysql

首先 docker ps 查看有没有启动，如果没有启动的话 docker ps -a 查看失败任务，或者docker logs -f 容器id

在my.cnf配置文件里面 加了 skip-name-resolve  直接导致mysql 启动不。别急

首先我们 把 docker cp 容器id:/etc/mysql/my.cnf /root/my.cnf   配置文件考出去，然后编辑。

如下

docker cp 77e675d2e390:/etc/mysql/my.cnf /root/my.cnf

下面是初始的配置。

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
 

然后esc +冒号 +wq 保存退出，再把文件拷贝回去

docker cp /root/my.cnf 77e675d2e391:/etc/mysql/my.cnf

最后重启docker restart mysql 成功。
