标题: 【转载】mysql服务不能启动，解决方法

查看mysql日志时出现以下报错

vi  /home/mysql/var/localhost.localdomain.err

160426  3:17:26 [ERROR] Aborting

Can’t create/write to file ‘/tmp/’ (Errcode: 13)

So, let’s see what an error 13 really means:

perror 13

And we see it’s a permission denied error:

[my@server ~]$ perror 13OS error code 13: Permission denied

The solution?

Set the correct owner and permissions to /tmp by running this commands:

chown root.root /tmp -vchmod 1777 /tmp -v

Now restart MySQL to test it:

/etc/init.d/mysqld start

That’s all, now your MySQL server should be able to start without any warnings or failures:

[my@server:~]service mysqld startStarting mysqld:
