Hi,

I'm trying to setup the following webserver configuration:
1. A Fedora 9 webserver.
1. With multiple IP aliases (currently 6 configured and working)
2. With multiple Tomcat servers (Currently one running OFBiz on port 8080 and 8443)
3. All connected through a HTTPD as a proxy server(was running as a webserver on port 80)

The whole idea is that I can reach Tomcat server instance 1 from IP alias 1, Tomcat server instance 2 from IP alias 2, etc...

I tried to reconfigure the httpd.conf to get the ajp-proxy and ssl working. When restarting httpd (or stopping and starting), it failed. I probably made some stupid error, but running debug mode doesn't make me any wiser why it failed, here's the output:

So, anyone got an idea why my httpd server failed to start?

What output does this produce:

# apachectl -t

?

[root@localhost ~]# apachectl -t
Syntax OK

Hmm. Can you explain what you meant by this, then?

Please copy and paste exact commands/output.

This:

[root@localhost ~]# service httpd status
httpd is stopped
[root@localhost ~]# service httpd start
Starting httpd: [FAILED]

Tail /var/log/messages the next time you try to start it. Any clues?

Also, this might provide a starting point for troubleshooting:
# bash -x /etc/init.d/httpd start

The debug chatter should help narrow things down a bit.

/var/log/messages doesn't give much info.

[root@localhost log]# tail messages

What seems strange to me is this entry a bit earlier in the messages file:
Dec 3 23:35:57 localhost NetworkManager: <info> (eth0): cleaning up...
Dec 3 23:35:57 localhost NetworkManager: <info> (eth0): taking down device.

I did took down the NetworkManager deamon:
[root@localhost log]# service NetworkManager status
NetworkManager is stopped

Van you make something of this? :S

I was hoping that might show some selinux-related messages.

Well, that doesn't tell us much we did not already know (i.e. httpd can't start) - perhaps because stderr is suppressed. Try from the command line, simply:
# /usr/sbin/httpd

Any error message?

If that shows nothing, my next step would be to remove any tomcat directives from httpd.conf (i.e. your connector) and try again.

Thanks for the tips! Here's what I found out commenting out rules in httpd.conf

This virtual host starts:
<VirtualHost 192.168.2.25:80>
ServerAdmin root@localhost
DocumentRoot /var/www/html/
ServerName localhost
# ErrorLog /var/log/httpd/ds_error_log
# LogLevel warn
# CustomLog var/log/httpd/ds_access_log common
ProxyRequests off
ProxyPreserveHost on
ProxyPass / ajp://localhost:8009/
</VirtualHost>

And this one does not:
<VirtualHost 192.168.2.25:80>
ServerAdmin root@localhost
DocumentRoot /var/www/html/
ServerName localhost
ErrorLog /var/log/httpd/ds_error_log
LogLevel warn
CustomLog var/log/httpd/ds_access_log common
ProxyRequests off
ProxyPreserveHost on
ProxyPass / ajp://localhost:8009/
</VirtualHost>
So I am guessing it's some kind of permission issue with the log file?

BTW: Still a lot of other problems, like the SSL Virtual Host won't start and in my webbrowser it gives an internal server error 500, but let's first try to solve this one.

What happened when you started httpd from the command line as we discussed?

You may need to create the logs for that virtual host:

# touch /var/log/httpd/ds_error_log

# touch /var/log/httpd/ds_access_log

Hmmm, that simple! It works perfect, including SSL etc. Thanks for the tips.
