Could not bind to address 0.0.0.0:80

Permission denied: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs

In Apache i faced the poblem for quite a long time and after searching in the net, i got a solution and from then onwards this problem wont occurs in my linux machines.
Go to apache conf file(i.e)httpd.conf

Append the lines as given below
#ServerName www.example.com:80
ServerName 192.168.1.230

Here 192.168.1.230 is my local ip.so you just type your local ip in the httpd.conf file.
