Mysql unable to reboot the wrong WARLING: World-Writableconfigfile '/ etc / my.cnf'Ignore solution
Problem analysis
The command to close the database found that mysql could not be closed, prompting Warning: World-writable config file '/etc/my.cnf' is ignored
, which probably means that the permissions are globally writable and can be written by any user.mysql is worried that this file will be maliciously modified by other users, so ignore this configuration file.So mysql cannot be closed.
Let’s take a look at the whole process
Restart MySQL
[root@ttlsa ~]# service mysqld stop Warning: World-writable config file'/etc/my.cnf' is ignored Warning: World-writable config file'/etc/my.cnf' is ignored MySQL manager or server PID file could not be found![FAILED]
You can see that mysql can't stop
View the permissions of my.cnf
[root@ttlsa ~]# ls -l/etc/my.cnf -rwxrwxrwx 1 root root 4878 Jul 30 11:31/etc/my.cnf
Permission 777, any user can change my.cnf
, there is a big security risk.
Fix MySQL issues
[root@ttlsa ~]# chmod 644/etc/my.cnf
my.cnf is set to be readable and writable by users, but not writable by other users.
Close MySQL
[root@ttlsa ~]# service mysqld stop Shutting down MySQL..[ OK ]
MySQL shut down successfully.The problem is simple
