a normal running apache server would have the following output(Output1), when you run linux command shell> ps -ef | grep httpd
Output1:
root 1373 1 0 15:34 ? 00:00:00 /usr/sbin/.libs/lt-httpd -k start -DSSL
apache 1375 1373 0 15:34 ? 00:00:00 /usr/sbin/.libs/lt-httpd -k start -DSSL
apache 1376 1373 0 15:34 ? 00:00:00 /usr/sbin/.libs/lt-httpd -k start -DSSL
apache 1377 1373 0 15:34 ? 00:00:00 /usr/sbin/.libs/lt-httpd -k start -DSSL
apache 1378 1373 0 15:34 ? 00:00:00 /usr/sbin/.libs/lt-httpd -k start -DSSL
apache 1379 1373 0 15:34 ? 00:00:00 /usr/sbin/.libs/lt-httpd -k start -DSSL
root 1387 26065 0 15:34 pts/6 00:00:00 grep httpd
My Case:
However, i only have following output (Output2), when i run linux command shell> ps -ef | grep httpd
Output2:
apache 30008 1 0 Mar27 ? 00:00:00 /usr/sbin/.libs/lt-httpd -k start -DSSL
When i try to restart the apache server via command shell> /sbin/service httpd restart
i get the following error show (Output3),
Output3:
Stopping httpd: [FAILED]
Starting httpd: [Thu May 17 14:47:56 2012]
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
Solution:
The lt-httpd service is part of the Apache server's service, hence i make up the decision to kill the process shell> kill 30008
After the process being killed, i'm able to start and stop my apache server again.
Explanation:
The reason of why only one and the only "/usr/sbin/.libs/lt-httpd -k start -DSSL" in the services list, if because due to the incomplete startup of the apache server after the physical server restart. Which then had causing the port 80 being hold by the handicapped apache service.
Because the restart features of the apache not able to shutdown the handicapped apache service, hence it always throw exceptions/error when you trying to restart/stop the apache server.
