You need to edit your httpd.conf.
Line 58 is first, if you want your server to be accessible by all network connections on that server then you can just type in:
Listen 80
where 80 is the port apache is listening on (the usual http port). You will need to make sure you don't already have another application listening on that port though!
Would be good to change ServerName on line 217 however its not necessary (for instance mine is set to 127.0.0.1:80)
Then you need to modify any directories and/or VirtualHost declarations that contain an "Allow from 127.0.0.1" rule.
You'll probably want to use the CIDR format to specify address ranges that can connect to the directories/virtualhosts, see [
en.wikipedia.org]
One of my virtual directories has the following config that allows any computer on my local network to connect:
Allow from 127.0.0.1 192.168.0.0/24
Use a space to separate values, the example above allows 127.0.0.1 and the range 192.168.0.0 - 192.168.0.255.
This is a quick start. You really need to read the apache documentation for each configuration value, especially if you are going to allow internet access to this server. Considering you are asking how to do this simple configuration, I would strongly advise you don't allow internet access to your server until you learn more about configuring and securing apache. Please don't take that as an insult, its meant as a warning, I don't want you to get hacked.
