Mysqld won't start with Selinux enforcing turned on
 

Guys,


I changed the default data location for mysql. Modified my.cnf on /etc.

Give mysql access to the new directory and moved the databases over.


Everything works fine. But when I turn selinux to 'enforcing', mysqld won't start.

How do I workaround this and be able to still have selinux be in 'enforcing' mode


Thanks in advance.

John

The context for the directory has to be correct, so for example
so "chcon system_u:object_r:mysqld_db_t /path/to/directory" should help

Billymayday,

I finally got around to try it but I don't have any luck. Getting "Timeout error occurred trying to start MySQL Daemon."


selinux is off

[root@centos53a ~]# ls -dZ /var/lib/mysql
drwxr-xr-x mysql mysql system_u:object_r:mysqld_db_t:s0 /var/lib/mysql


[root@centos53a ~]# ls -dZ /u03
drwxr-xr-x mysql mysql /u03


*** I did the command you suggested below, /u03 is the new location of mysql in my.cnf file ***

[root@centos53a ~]# chcon system_u:object_r:mysqld_db_t:s0 /u03


[root@centos53a ~]# ls -dZ /u03
drwxr-xr-x mysql mysql system_u:object_r:mysqld_db_t:s0 /u03

selinux is on

reboot

*** after reboot, it shows the following***

[root@centos53a /]# ls -dZ /var/lib/mysql
drwxr-xr-x mysql mysql system_u:object_r:mysqld_db_t /var/lib/mysql



[root@centos53a /]# ls -dZ /u03
drwxr-xr-x mysql mysql system_u:object_r:mysqld_db_t /u03

Finally got it to work with the following:



chcon -Rv --type=system_u:object_r:mysqld_db_t my_new_dir

I just needed to give both the files and directory access.

Thanks again.
