我正在尝试连接到我的CentOS 7上安装的MariaDB / Mysql，并在尝试连接时遇到以下错误： mysql -u root -p .

ERROR 2002(HY000)：无法通过套接字'/var/lib/mysql/mysql.sock'连接到本地MySQL服务器(111)

我尝试通过指定IP地址而不是使用localhost来连接它，但我得到了同样的错误 .

当我尝试获取MariaDB状态时，我收到以下消息( /bin/systemctl status mariadb.service )：

mariadb.service - MariaDB数据库服务器已加载：已加载(/usr/lib/systemd/system/mariadb.service;已启用;供应商预设：已禁用)活动：失败(结果：资源)

并启动它会产生以下错误( /bin/systemctl start mariadb.service )：

mariadb.service的作业失败，因为超出了配置的资源限制 . 有关详细信息，请参阅“systemctl status mariadb.service”和“journalctl -xe” .

我还查看了位于/var/log/mariadb/mariadb.log的日志
