mysqld and selinux? cant start mysqld


hey guys hopefully someone has the answers for this but
these are my errors

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib /mysql/mysql.sock' (2)

and in my /etc/log/mysqld.log

150403 0:30:26 [Note] /usr/libexec/mysqld: Shutdown complete
150403 00:30:26 mysqld ended
150403 00:58:32 mysqld started
150403 0:58:32 [Warning] Can't create test file /mnt/xfsdisk/mysql/cts4348-node-8.lower-test
150403 0:58:32 [Warning] Can't create test file /mnt/xfsdisk/mysql/cts4348-node-8.lower-test
/usr/libexec/mysqld: Can't change dir to '/mnt/xfsdisk/mysql/' (Errcode: 13)
150403 0:58:32 [ERROR] Aborting


and this is my.cnf file

[mysqld]
datadir=/mnt/xfsdisk/mysql/
socket=/mnt/xfsdisk/mysql/mysql.sock
user=mysql


-----------------------------------

i tried these commands to fix them, but still sam eproblem


926 semanage fcontext -a -t mysqld_db_t /mnt/xfsdisk/mysql/
927 semanage fcontext -a -t mysqld_db_t /mnt/xfsdisk/
restorecon -Rv /mnt/xfsdisk/mysql/
semanage fcontext -a -t mysqld_db_t "/mnt/xfsdisk/mysql(/.*)?"


nothing seems to work? any ideas where to point me? (also I do not have a [client] in the my.cnf file.


i am also using centos5....the funny part is it was working just fine. i tried to install mantis but i dont know if that is the problem?

...you're connecting your mysql client to the mysql service over a specific socket name,

...and you haven't shown us ('grep mysql /var/log/audit/audit.log|audit2allow;') if SELinux is the problem.

Decide if you need or want the default section after reading the documentation.

It was your intention to install the Mantis bug tracker but you created or compounded problems by also chosing to change the default directory MySQL. Also note your "/mnt/xfsdisk" is line "/var/lib" and it MUST NOT have the same context as "/var/lib/mysql" or "/mnt/xfsdisk/mysql". So next to compounding things you also managed to skew things further. I suggest you restore everything back to defaults and then you will see the installation will work just OK. If you can't for some reason then ensure the fix you're applying is the correct one and please be precise applying it.
