Hi,
we installed apache(httpd-2.0.63) on red hat4.2 for proxy server.
when i tried to run, we got the error like

Syntax error on line 147 of /usr/local/apache2/conf/httpd.conf:
module auth_module is built-in and can't be loaded


our requirements are
1,
In our local network(lan),the devloper type like http://ora.yan.com:8050/
for accessing the applications
but we want,
whenever the user type the url like http://xyz.pivotix.com from the world,
it will automatically invoke the applications(http://ora.yan.com:8050/)



2,
And also we bought SSL certificate.
How to enable the certificate in Newly installed apache.


3,
we want Only https connection

How did you install apache? Apache generally comes pre-installed in Red Hat so it sounds like you messed something up pretty badly there? at most you should have just done a yum install or yum update on it.

1. Sounds like your after port-forwarding. If they are browsing to the site just forward the port on the firewall/router. Else wise do a php forward to the ip or set the DNS entry at the DNS register with the port number on IP... I believe this can be done but not certain on it.

2. RHEL comes with openssl, I believe your going to have to look into that, I am afraid I can't guide you through this one, never set-up SSL to date tho will have to in the near future...

3. This will make the links in 1# not work, they'd have to be https you are aware of this? if so, just block port 80 in iptables for a simple way to do it, you can also change the listen ports in the apache configuration. There is probably a method to turn off just the http links in other ways but if your not listening to http traffic then you should still block port 80.

For RHEL 4.x it's up2date; yum came in for v5.x. Here's a good x-ref and examples

I agree that using the RHEL pkg mgr is the way to go.

Sounds like you may want the mod_rewrite module for Apache to re-direct cxn to port 80 => 443.
