Docker无法通过套接字'/var/run/mysqld/mysqld.sock'连接到本地MySQL服务器(2)Ubuntu

Question

我正在玩docker并将我的本地mysql挂载到docker容器并连接MySql-Workbench所以我可以查看DB(试验)这里是我运行的命令.

docker run -d --name alldb-mysql -v /var/lib/mysql:/var/lib/mysql -e MYSQL_USER=root -e MYSQL_PASSWORD=password -p 3306:3306 mysql:latest

在我停止我的容器并将其删除后,我无法启动/重启mysql(本地安装).当我跑sudo /etc/init.d/mysql start它返回

[....] Starting mysql (via systemctl): mysql.serviceJob for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
 failed!

所以我查了一下 systemctl status mysql.service

我还尝试使用我的详细信息登录mysql: mysql -uroot -ppassword1返回了

mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

当我ls -la /var/lib/ | grep mysql在var lib目录上运行以下命令时它返回.

drwx------ 12 root          docker        4096 Apr  3 21:17 mysql
drwx------  2 mysql         mysql         4096 Feb 23 22:35 mysql-files

drwxr-xr-x  2 root          root          4096 Jan 18 21:45 mysql-upgrade

通过看起来我(很好的码头工具)搞砸了我在mysql目录上的所有权.

如果我运行ls -la /var/lib/mysql 它返回

ls: cannot open directory '/var/lib/mysql': Permission denied

并sudo ls -la /var/lib/mysql 返回与sudo运行相同的命令

通过这看起来,我(好船坞人)设法改变了mysql目录中所有目录的所有者和组.

我是否需要完全重新安装MySQL服务器？

解决这个问题最简单,最简单的方法是什么？

非常感谢您的帮助.

更新了FIX

正如Andy Shinn在第一点所说的那样,我只是跑sudo chown -R mysql:mysql /var/lib/mysql回去改变主人并通过运行启动mysql sudo /etc/init.d/mysql start并返回mysql

Answer 1

将需要更多信息.但有两件事情浮现在脑海中.

1. 很可能是许可问题.根据您的输出,为什么不首先尝试将所有者和组更改回mysql？这应该很简单sudo chown -R mysql:mysql /var/lib/mysql.
2. 运行mysql:latest映像可能是您在本地运行的MySQL的不同版本,它可能已将MySQL数据升级为较新的格式,这可能与旧版本不兼容.检查您在本地运行的MySQL版本是否与mysql:latest图像标记指向的版本相同(至少是相同的次要版本,例如5.6和5.6).

什么版本mysql:latest以及您在本地运行的版本是什么？你有从MySQL容器启动的任何日志输出吗？
