Plesk Subdomain with www Fix
Add one line to the special configuration file for the subdomain.
Normally this file is located in /srv/vhosts/yourdomain/subdomains/yoursubdomain/conf/vhost.conf .
If you do not see the vhost.conf file then go ahead and create it with the following text:
ServerAlias www.yoursubdomain.yourdomain.com
If you do not have write permissions, you will probably have to do this work via SSH.
What does ServerAlias www.yoursubdomain.yourdomain.com mean?
This is a Apache configuation that says that Apache will also serve the subdomain if you access it with www. This is normally used for the domain name, but also working for sub-domains.
If your www.yoursubdomain.yourdomain.com is not accessible please follow the next steps:
- Add a record type in the DNS zone of the domain for the subdomain starting with www. Select the following menu entries:
Server => Domains => yourdomain.com => DNS Settings - There you'll see a list of DNS entries for the domain. Check the IP address for the subdomain entry - copy to clipboard or write it down for reference (you will need it a minute!)
- Now you create a new entry with the button Add new entry - use the following values:
- Record type: A
- Domain name: www.yoursubdomain
- IP address: enter the IP address that you copied in step 2, e.g. 123.123.123.123
-
Check if there is a new entry wit the following value:
www.yoursubdomain.yourdomain.com A
123.123.123.123
Recreate the Plesk / Apache configuration for the whole domain via SSH:
/usr/local/psa/admin/sbin/websrvmng -u --vhost-name=yourdomain.com
Restart Apache to read the new configuration and serve pages with www.yoursubdomain.yourdomain.com via SSH:
apachectl restart
