Failure when start service httpd on Fedora 18

hai guys, i try install Feodra 18
mmm.. when i try install and start service httpd on my fedora 18. i find problem when will start service httpd.

this tutorial i can share the solution for this problem.

when typing :
sudo service httpd start 

service respone and show this message :
Job for httpd.service failed. See 'systemctl status httpd.service' and 'journalctl -xn' for details.

you can check for the problem using :
sudo systemctl status httpd.service

and will show log:
httpd.service - The Apache HTTP Server
      Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled)
      Active: failed (Result: exit-code) since Sun 2013-01-27 00:26:20 WIT; 9s ago
     Process: 7518 ExecStop=/usr/sbin/httpd $OPTIONS -k graceful-stop (code=exited, status=0/SUCCESS)
     Process: 7516 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE)

and then,
sudo journalctl -xn

and will show log:
-- Unit httpd.service has failed.
--
-- The result is failed.
Jan 27 00:26:20 tkl systemd[1]: Unit httpd.service entered failed state
Jan 27 00:26:30 tkl systemd[1]: SELinux Got Sender :1.132

 now, you can cek your ServerName in /etc/httpd/conf/httpd.conf and config same with this :
ServerName localhost

cek your error log when will start your service using :
sudo tail -f /var/log/httpd/error_log 

and in my fedora show :
[Sun Jan 27 00:29:38.704621 2013] [core:notice] [pid 7770] SELinux policy enabled; httpd running as context system_u:system_r:httpd_t:s0

AH00016: Configuration Failed
 
check your hostname in /etc/hostname
tkl

and  check your /etc/hosts, if in your configuration sam with this :
127.0.0.1        localhost.localdomain localhost

you can change with example :
127.0.0.1        localhost    tkl

now, edit  your SELINUX in /etc/selinux/config, SELINUX=disable
# 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=disable
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted  

now, you can try
sudo service httpd start 

and enjoy guys.. :)
