Check httpd status after installing Apache "httpd dead but Subsys locked" issue

This issue is encountered when installing deployment ganglia, and the httpd version 2.2.15,centos version is 6.4.

Installation method:

<span style= "Color:rgb (221, 221, 221); Font-family:monospace; line-height:22px; Background-color:rgb (51, 51, 51); " >yum Install httpd</span>

After the installation is complete, start everything to display normally, but when viewing the httpd status:

Service httpd status
httpd dead but Subsys locked

Try to delete the lock:

sudo rm-f/var/lock/subsys/httpd

No effect, then restart httpd, error:

Service httpd Restart
stopping httpd: [FAILED]
starting httpd: (98) Address already in use:make_sock:could not bi nd to address 10.10.26.11:80
No listening sockets available, shutting down
unable to open logs
[FAILED]

So, all kinds of internet Google find ways, have not solved.

Then check httpd.conf found that the Pidfile variable is set to Run/httpd.pid by default and turns it to/var/run:

Pidfile/var/run/httpd.pid

Also in/ETC/SYSCONFIG/HTTPD modify:

Pidfile=/var/run/httpd.pid

Kill the httpd process (or kill it via Port lookup):

Killall-9 httpd

To delete a lock:

sudo rm-f/var/lock/subsys/httpd

Restart httpd:

sudo service httpd restart

This solves the problem:

Service httpd status
httpd (PID 14331) is running ...
