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.

G 1> Andy Shinn..： 将需要更多信息.但有两件事情浮现在脑海中. 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. 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？ |
