超出 MariaDB/MySQL 资源限制

【中文标题】超出 MariaDB/MySQL 资源限制

【英文标题】：MariaDB/MySQL resource limit was exceeded

【问题描述】：

我正在尝试连接到安装在我的 CentOS 7 上的 MariaDB/mysql，并在尝试连接时收到以下错误：mysql -u root -p。

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

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）

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。详见“systemctl status mariadb.service”和“journalctl -xe”。

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

有人对如何修复此错误有任何想法吗？

谢谢你:)

【问题讨论】：

检查 mysql 错误日志并在可用时从那里发布相关诊断。请参阅***.com/questions/33700660/… 以获取日志的位置。

感谢您的帮助 :) 由于 mysql/mariadb 未运行，我无法使用推荐的技术获取日志。但是我在“/var/log/mariadb/mariadb.log”中找到了日志文件并将内容添加到我的问题中。

【参考方案1】：

> perror 28
OS error code  28:  No space left on device

需要我多说吗？
