mysql - 无法在 debian 10 上启动 MariaDB

问题描述

我似乎无法再启动 mariadb sql 了。互联网说了一堆东西，但它们似乎都是“有风险的”，而且似乎真的取决于具体情况。所以这里是我的。我不知道发生了什么/何时发生，但我害怕丢失我的订阅者数据。超级英雄们，你们有什么建议？当我尝试启动 mariadb 时：

me@server:# systemctl start mariadb.service
Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.

并使用 systemctl status mariadb.service：

me@server:# systemctl status mariadb.service
● mariadb.service - MariaDB 10.3.27 database server

当我去 journalctl -xe 时，我只得到：

这不是一个很大的帮助，我不知道该怎么做。我真的不想丢失我的数据库。感谢您的输入

解决方案

通过删除/重命名 tc.logmv -vi /var/lib/mysql/tc.log /root并重新启动数据库来解决它service mysql restart
