ps -ef|grep mysql
发现里边没有mysql进程,于是进行重启。

service mysqld start报错
查看错误日志
tail -100 /usr/local/mysql/var/iZ11yohng9aZ.err(主机名.err)

可以看到,错误日志中出现的错误信息: Failed to open log (file ‘./mysql-bin.000901‘, errno 2)

于是尝试解决方案如下:

cd /usr/local/mysql/var/
cp mysql-bin.index mysql-bin.index.bak(备份)
vi mysql-bin.index
删除其中的mysql-bin.000901

然后进行重启,mysql启动成功
