if u see this type of problem in apache webserve build in linux rh 7,9, 2.1 as, and other newer version

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:443

or

(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80


do the following :

vi /etc/httpd/conf/httpd.conf

and replace the port 80 and port 443 with
port 80--->88
port 443 --> 448 for the timebeing.

to do quick find vi the file and than presh escap key and than put the ? question mark and than type 80 or 443 . to fine other 88 entry press n on the same time. anyhow let me kick ur ass now bcoz not suppose to teach all these things now..

well when u replaced them than u simply run the command

service htttpd restart
again to confirm service httpd restart

than see if it has started

service httpd status...
than u will see that ur webserver is started on port 88 and 448 for ssl. hummmmm

now try to browse http://ipaddressof ur linuxbox:88
http://ipadr:443

u will see that ur page is cameup...hummmmmmm but problem is not solved yet.
this teaches us that the prblem is with the port conflict..how can u track it..

put the command

lsif :80

u will see the several process are already running on port 80 so apachea can't start on the same port. so u have to kill all these apachea process using kill -9 <processid>

my logs:

Why this problem comes:
-------------------------------
this problem is comes only if u started the weberver and than made some modification or tried to load the jsp or asp support than u will find http locked when u tried to restart it .

so don't be confussed. just kill th process and than put ur configuration (original file) which has port 80 or 443.

it will work fine......
