Maria db 无法启动 | 无法获取 D-Bus 连接

我尝试启动 mariadb，但无法启动 maria db，我不知道为什么。我正在运行带有 mariadb 的 centos 7。当我重新启动时它无法启动，当我使用 cli 启动它时，它显示以下内容：

    [root@localhost mariadb]#  systemctl start mariadb.service
    Job for mariadb.service failed. See 'systemctl status mariadb.service' and 'journalctl -xn' for details.

当我检查日志时，它给出了这个错误：

[root@localhost mariadb]# journalctl -xn

我该如何修复无法获取 D-Bus 连接：无法连接到套接字 /var/run/dbus/system_bus_socket：没有此文件或目录错误？

答案1

使用以下方法可修复：

[root@localhost mariadb]# nano /etc/my.cnf

然后我取消注释了我的 pid 文件

#pid-file=/var/run/mariadb/mariadb.pid

然后我重新启动了 mariadb
