Webmin / Virtualmin

Webmin / Virtualmin

Webmin is the web-based configuration tool provided by default with Accelerators. It runs as its own process, and includes its own web server.

After customizing your Accelerator, you may find that you eventually need to upgrade the Webmin / Virtualmin software. Alternatively, you may also decide that you prefer to monitor and configure your system exclusively with an SSH session.

Upgrading

Preflight

Get to the Upgrade Webmin area

Log into your accelerator https://1.2.3.4:10000/ as admin
From the left-hand navigation bar select Webmin
From the left-hand navigation bar select Webmin below Login: admin
Select Webmin Configuration
From the right-hand tab select Upgrade Webmin

Find out what is out of date

You will be presented with a list of items which require updating and what has changed.

From the Update modules tab
Select Only show which modules would be updated checkbox
Select Update Modules

You then can uncheck the show and actually perform the updates.

Virtualmin is considered a non-core module, so you need to check that option (Update non-core modules as well) too to include it in any updates.

Setting automatic update schedule

Select the Scheduled update tab
Check the Scheduled updating currently enabled box
Set your desired schedule

Upgrading Webmin

From the Upgrade Webmin tab
Then chose from where you wish to upgrade from, typically Latest version from www.webmin.com
Select the Upgrade Webmin buttton

Removing

You may decide that you do not want to use Webmin at all and wish to manage your Accelerator solely using SSH.

If you want to remove Webmin completely, open a new SSH session.

Change to root: sudo su -
Disable the Webmin service: svcadm disable svc:/application/webmin:default
Then execute the Webmin uninstall script:

sudo /etc/webmin/uninstall.sh

Finally, remove the Webmin manifest: svccfg delete svc:/application/webmin:default

Changing webmin passwords

If you forget your webmin password, run the command below. You may have to change the path based on your webmin version. “admin” is the webmin “root” user.

sudo /opt/webmin-1.340/changepass.pl /etc/webmin admin new_password

Restarting

If Webmin becomes unresponsive or unreachable, you can restart it from an ssh session.

Login as an administrative user.
Restart Webmin: sudo svcadm restart webmin
Make sure Webmin is not in maintenance: svcs -x
If Webmin is listed as being in maintenance, run:
sudo svcadm clear webmin
