After installing OpenMediaVault, the first thing you should do is enable HTTPS encryption for web access. This ensures that when you access the OMV web interface, all data is encrypted with HTTPS.
You should activate this option, especially if you also want to access your OMV instance via a public network.
What you have to do is described in the following article.
Safety instructions
I know the following hints are always a bit annoying and seem unnecessary. But unfortunately, many people who knew it "better" from carelessness lost their eyes, fingers or other things or hurt themselves. In comparison, a loss of data is almost not worth mentioning, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Even the coolest project is worth no injury or other annoyance. https://www.nerdiy.de/en/sicherheitshinweise/

Create SSL certificate under OpenMediaVault
You should activate HTTPS encryption especially if you are accessing via a public network. This can be, for example, the Internet or an unencrypted WiFi network.

To do this, open the web interface of your OpenMediaVault installation.
Then click on the "System" tab and on the "Certificates" subcategory.

You will then be redirected to this view.
Here you can set the properties and descriptions of the certificate. The empty fields in the picture are optional.
Of course, you can also set the term of the certificate to be longer.
Click "Create" to apply the settings.
Activate login to the web interface via HTTPS
After you have created the SSL certificate, you can now activate the HTTPS encryption.

You should also check the box at
- SSL/TLS enabled
other
- Force SSL/TLS
Then click on "Save" to apply the changes.
Test HTTPS encryption
In order to be able to access the web interface of your OpenMediaVault installation, you must call it with an https:// in front. If the address of your OpenMediaVault instance is "omvtestserver", you must now enter
- https://omvtestserver
into the address bar of your web browser to access the web interface.

You will most likely get this error message.
This is displayed to you because you are using a self-signed (ie unknown to the browser) certificate.
In most cases, however, this is harmless. You can then resolve the error message by clicking on "Advanced" and…

This completes the installation of OMV. I have described the many other functions in other articles. There you will also find information on how to expand the functionality of your OMV installation accordingly. These articles are all grouped into the following categories.
Have fun with the project
I hope everything worked as described. If not or you have any other questions or suggestions, please let me know in the comments. Also, ideas for new projects are always welcome. 🙂
P.S. Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you appreciate that I share this information with you, I would be happy about a small donation to the coffee box. 🙂
