Answer 1

I went to server admin with this problem and he changed configuration in centos

in folder /etc/sysconfig/

he edited file selinux and change SELINUX=disabled and restated it.

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled

and my problem got solved.
