Providing Miva for Virtual Subhosts

To provide Miva support for a Virtual Subhost with Miva support, we recommend that you use Miva's <VirtualHost> configuration directive.

Be sure that you are running the latest version of Miva (at the time of this writing, it is v.3.57). One way to check for this is by looking for the version number in the first couple of lines of the Miva configuration file, ~/etc/miva.conf. If you are not running v.3.57, you should consider Upgrading Miva/HTMLScript.

Be sure that the following parameters are set in miva.conf:

virtualhostvariable=SERVER_NAME
dnslookup=0

NOTE: If you choose to set virtualhostvariable=HTTP_HOST, then your miva.conf must have a <VirtualHost> directive for each of the virtual subhost's domain names. For example, using 'HTTP_HOST' will require both subhost-domain.com and www.subhost-domain.com to have its own <VirtualHost> directive in miva.conf. This is why we recommend using 'SERVER_NAME' instead, because in your httpd.conf, you can consolidate a virtual subhost's multiple host names under a single <VirtualHost> directive with just one ServerName. This is documented in the instructions below.

Add the <VirtualHost> directive to miva.conf. Assuming that you are using virtualhostvariable=SERVER_NAME in miva.conf, the name of the <VirtualHost> should equal the ServerName for the subhost defined in the <VirtualHost> directive for your web server in your httpd.conf.
Ideally, the mivaroot parameter should equal the virtual subhost's DocumentRoot (another parameter of the <VirtualHost> directive in httpd.conf).

The stdmodedatadir should be outside of the ~/www/htdocs directory, unaccessable by others, since all data collected by Miva will be stored in that directory.

The VirtualHost directive in miva.conf should look something like this:
```
<VirtualHost www.SUBHOST-DOMAIN.NAME>
mivaroot=/usr/local/etc/httpd/htdocs/SUBHOST-DOMAIN-DIR
stdmodedatadir=/usr/local/etc/httpd/miva/SUBHOST-DOMAIN-DIR_data
mivadefault=index.html 
serveradmin=webmaster@SUBHOST-DOMAIN.NAME
</VirtualHost>
```
You may or may not need to modify your web server configuration file, httpd.conf, depending on the method you are using to give your virtual subhost's CGI support. After ensuring that the parameters defined in the <VirtualHost> directive in httpd.conf matches those you set in the <VirtualHost> directive of miva.conf, you must check if your subhost has access to the Miva engine that was put in your ~/www/cgi-bin during the Miva installation.
If the virtual subhost is sharing your virtual server's primary cgi-bin directory--meaning that you have not explicitly identified an alternate ScriptAlias for the subhost in the <VirtualHost> directive of httpd.conf--then after following all the instructions above, Miva should be setup and ready to support your virtual subhost. If you don't understand what a ScriptAlias is, then your virtual subhost is probably using your primary cgi-bin directory and the Miva engine therein, so you don't have to worry about making anymore changes. Go on to the next step.

However, if the virtual subhost has its own cgi-bin directory, then we would recommend that you give that virtual subhost access to the Miva engine in your primary cgi-bin directory by adding the following to your httpd.conf's <VirtualHost> directive:
```
ScriptAlias /cgi-miva/ /usr/local/etc/httpd/cgi-bin/
AddType application/x-httpd-Miva .mv
Action application/x-httpd-Miva /cgi-miva/miva
```

Test your setup by copying the Miva Maillist applet (it can be found in the /usr/local/contrib/miva_apps/maillist/ on your Virtual Server host machine) to your virtual subhost's mivaroot (which should be its DocumentRoot, assuming you followed the instructions above) and running it in your browser. For example:

% cp /usr/local/contrib/miva_apps/maillist/* ~/www/SUBHOST-PATH

Then, in your browser, access this URL:

http://SUBHOST-DOMAIN.NAME/maillist.mv

When you run this applet, it should save the submitted data in the virtual subhost's stdmodedatadir in a file called mailing.dat. If not, review the instructions above along with your own setup for any configuration errors.

NOTE: If Miva still has problems running an application for a virtual subhost, or runs the application but stores data in the wrong directory, then delete all the files in your workdir (the default installation will have this set as ~/www/miva/workdir). This directory contains a caching database with virtual subhost configuration information. Deleting the database files will require Miva to reload the new VirtualHost information from miva.conf.
