mysql错误！服务器不更新PID文件就退出了吗?

问题描述

我的Vps mysql无法启动，当我尝试命令服务mysql start时出现此错误

My Vps mysql wont boot , when i attempt to command service mysql start i got this error

root@## [/var/lib/mysql]# service mysql start
Starting MySQL... ERROR! The server quit without updating PID file (/var/lib/mysql/***.***.com.pid).

这是my.cnf

这是错误日志

该如何解决?任何想法

推荐答案

140227 21:23:42 [ERROR] /usr/sbin/mysqld: unknown variable 'set-variable=100'

从配置文件中删除该行
