我是linux新手,安装软件也是胡乱安装,找了一篇文章。将mysql安装到一个特定文件下了,但后来压测handlersocket,mysql突然crash了。去启动怎么也启动不了,无奈呀!我安装mysql的文件夹在/opt/yq下,启动不了,自然去找错误日志了,但因为安装文件使用的默认方式,google了一下,说在按安装路径的data下,也确实找到了相关日志文件,文件名为***.err文件,发现里面的内容很旧,郁闷。说明后面启动mysql的错误日志没在这里。那在哪里呢?继续找,google后发现/data/mysql/下会有相关的日志,到里面后发现里面除了错误日志文件外还有数据文件,查看里面的错误日志:

发现红色部分,原来是磁盘满了,狂晕!ll -lh查看了一下文件大小 mysql-bin 数据库备份文件太大了,删除,重启问题解决了,哈哈!不错!
