Starting httpd: (98)Address already in use: make sock: could not bind to address 0.0.0.0:443

When

Restarting httpd service 

Error :

Starting httpd: (98)Address already in use: make_sock: could not bind to address 0.0.0.0:443
no listening sockets available, shutting down
Unable to open logs!

Cause :

Simultaneous use of port by other processes in the server

Fix :

Following Steps need to be performed in-order to find its fix

Lets consider the process crond using the port

1. now run the below command

netstat -lnp | grep '0.0.0.0:80'

2. if output is as following

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 30982/crond

then stop the process which is using the port (in our case it is “crond”) as below

service crond stop

3. then run following

service httpd restart

this should give as below

Stopping httpd: [FAILED]
Starting httpd: [ OK ]

and later start crond service as following

service crond start

Everything should work fine.
