我正在使用docker并将我的本地mysql挂载到docker容器并连接MySql-Workbench所以我可以在这里查看数据库(试验)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
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)。当我运行sudo /etc/init.d/mysql start
时,它会返回
[....] 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!
所以我检查了systemctl status mysql.service

我还尝试使用我的详细信息登录mysql:
返回的mysql -uroot -ppassword1
mysql: [Warning] Using a password on the command line interface can be insecure.

当我在var lib目录上运行以下命令ls -la /var/lib/ | grep mysql
时,它返回。

通过我看到的东西(很好的码头工作者)搞砸了我在mysql目录上的所有权。
如果我运行ls -la /var/lib/mysql
,则返回

并使用sudo sudo ls -la /var/lib/mysql
运行相同的命令,它返回

从这看起来,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?
解决此问题的最简单,最简单的方法是什么?
非常感谢您的帮助。
已更新为FIX
正如Andy Shinn在第一点所说的那样,我只是运行
sudo chown -R mysql:mysql /var/lib/mysql
来更改所有者并启动mysql 通过运行sudo /etc/init.d/mysql start
和mysql返回
[ ok ]Starting mysql (via systemctl): mysql.service.
答案 0 :(得分:5)
还需要更多信息。但有两件事情会浮现在脑海中。
mysql
?这应该是一个简单的sudo chown -R mysql:mysql /var/lib/mysql
。mysql:latest
图像可能是您在本地运行的不同版本的MySQL,它可能已将MySQL数据升级为更新的格式,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)。 mysql:latest
是什么版本以及您在本地运行的版本是什么?你有从你开始的MySQL容器的任何日志输出吗?
