Greetings,

I am an IT intern at a small communications company. My assignment is to set up a Red Hat Enterprise Linux 6 Server to run both Zimbra email client and Apache Web Server (to be used to run an SVN client as well as TRAC). This is something I've done before with a different server, possibly running different versions of each program. What I did before doesn't seem to work any more. Here's what I did:

1) install both Apache and Zimbra
2) Configure Zimbra to listen to port 81
3) Set up httpd to use Virtual Hosts. This is what my httpd-vhosts.conf file looks like:

NameVirtualHost 10.105.249:80

<VirtualHost 10.105.249.32:80>

ServerAdmin admin@xxxxxxxxxxxxxxxxxx

DocumentRoot "/httpdir"
ServerName svntrac.incnetservices.net
ServerAlias svntrac.incnetservices.net

ErrorLog "logs/error_log"
CustomLog "logs/access-log" common
</VirtualHost>

<VirtualHost 10.105.249.32:80>

ServerAlias incemail.incnetservices.net
ProxyRequests On
ProxyPass / http://incemail.incnetservices.net:81

ProxyPassReverse / http://incemail.incnetservices.net:81
ErrorLog "/var/log/httpd/zimbra-error.log"
</VirtualHost>

You can't use ServerAlias without a ServerName, in this case just replace it with ServerName.

<VirtualHost 10.105.249.32:443>
ServerAlias incemail.*
SSLProxyEngine On
SSLEngine On

SSLCertificateFile /opt/zimbra/ssl/zimbra/server/server.crt

SSLCertificateKeyFile /opt/zimbra/ssl/zimbra/server/server.key
ProxyPass / http://incemail.incnetservices.net:81
ProxyPassReverse / http://incemail.incnetservices.net:81/

ErrorLog "/var/log/httpd/zimbra_ssl-error.log"
</VirtualHost>

Same goes for this vhost.

When i start httpd with it gives me the error:

Starting httpd: Syntax error on line 23 of /etc/httpd/httpd-vhosts.conf:

Invalid command 'SSLProxyEngine', perhaps misspelled or defined by a module not included in the server configuration
[FAILED]

My problem seems to be with whatever module SSLProxyEngine is associated with. How do i fix this? Or better question, am i setting up the https v-host correctly?

You seem to be missing the mod_ssl module. Load it using LoadModule and restart Apache HTTPD, then you will be able to use the directives it provides, such as SSLProxyEngine.

I commented the https vhost section out and tried running httpd and it runs. However, the document root i specified isn't used at all, the default Apache page loads.

Check the output of 'httpd -S' to see the current VirtualHost configuration. If you are unsure if its correct or not, share it with the list.

Furthermore, the Zimbra admin and user log-in pages don't load at all. When I do an nslookup of the domains they do return the correct IP address, but it seems the browser won't return the correct information. Again, I'd like to point out that these are the exact specifications I used in the past, but will not work now. If anyone has experience with Zimbra and Apache, any help will be greatly appreciated!

Thanks!
