I've got a strange problem. I can not allow apache to connect to database at my CentOC 6.4 box:
[root@centos6 ~]# setsebool -P httpd_can_network_connect on
Killed
[root@centos6 ~]# sestatus -b | grep httpd_can_network_connect
httpd_can_network_connect off
httpd_can_network_connect_cobbler off
httpd_can_network_connect_db off
I watched log file, but there was no log messages:
tail -f /var/log/audit/audit.log
UPDATE:
There are some information in /var/log/messages:
