MariaDB 不会突然启动

Question

我有一些麻烦与我的MariaDB服务器，它工作正常，但它不会启动了。当我尝试启动服务器时，它失败了:

root@vps45223599:/var/log# /etc/init.d/mysql start
[....] Starting mysql (via systemctl): mysql.serviceJob for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.
failed!

root@vps45223599:/var/log# systemctl status mariadb.service

我不知道发生了什么事。我也试过

mysqlcheck

root@vps45223599:/var/log# mysqlcheck --all-databases -p
Enter password:
mysqlcheck: Got error: 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory") when trying to connect

我不知道我还应该尝试什么，有人能帮我吗?欢呼声

Answer 1

正如@obe所说，这可能是一个proxmox或其他没有足够权限的煽动系统的问题。

设备。允许错误可能是由MariaDB的systemd服务文件的PrivateDevices=true(似乎是基于未能提供更多信息的MDEV-13207)方面请求的。

PrivateDevices = true允许:

• /dev/null
• /dev/0
• /dev/随机

根据对不同设备的回答，对这些设备进行等效操作将是:

lxc config set mycontainer raw.lxc 'lxc.cgroup.devices.allow = c 1:3 rwm'
lxc config set mycontainer raw.lxc 'lxc.cgroup.devices.allow = c 1:8 rwm'
lxc config set mycontainer raw.lxc 'lxc.cgroup.devices.allow = c 1:5 rwm'

主要/次要设备代码由:

$ ls -la /dev/zero /dev/random /dev/null
crw-rw-rw-. 1 root root 1, 3 Jan  8 22:20 /dev/null
crw-rw-rw-. 1 root root 1, 8 Jan  8 22:20 /dev/random
crw-rw-rw-. 1 root root 1, 5 Jan  8 22:20 /dev/zero

谢谢大家的回答。@danblack没有任何变化，突然停止工作，但阅读这个论坛，我在这个线程中找到了解决方案。

可以't在debian 10上启动MariaDB

基本上解决方案是…通过删除/重命名tc.log文件mv -vi/var/lib/mysql/tc.log/root并重启数据库服务mysql restart"然后重新开始。
