I did see this post many times. But this is not the solution for me.

[root@server ntop-3.3.9]# service httpd restart
rm: cannot remove `/var/run/httpd.pid': Permission denied [ OK ]

rm: cannot remove `/var/run/httpd.pid': Permission denied
Starting httpd:
[root@server ntop-3.3.9]#


I do have this problem too.
I thought root is the highest access ?
Thank you for reply.
 
/var/run permissions are messed up

Turn off SELinux if it's on.

Make sure the files aren't chattr'd read-only.

[root@server ~]# cat /etc/selinux/config
# 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 - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted

# SETLOCALDEFS= Check local definition changes
SETLOCALDEFS=0




and then this

I cannot restart MySQL in here, but I can restart in DirectAdmin web interface.
Still cannot figure out what happen. I remember last time can restart normally in shell.

Did you try disabling SELinux?

Thank you for you reply.

I've show the root@server ~]# cat /etc/selinux/config in previous post that I've disable the selinux.

Then now I tried this too.
[root@server ~]# setenforce 0
setenforce: SELinux is disabled
[root@server ~]# service httpd restart
rm: cannot remove `/var/run/httpd.pid': Permission denied [ OK ]
rm: cannot remove `/var/run/httpd.pid': Permission denied
Starting httpd:
[root@server ~]#

Still the same. Wish can solve this problem.
 
Did you patch and build the kernel yourself, maybe with a RBAC system like the one from grsecurity?
Maybe your /var partition is mounted real-only (but the error should be different...), or you have some security LKM loaded, or your system has been compromised with a rootkit.
That's all I can think of at the moment.
