How to uninstall a rapid scada software in Raspberry Pi?

[Mikhail]

You can also edit WebSettings.xml manually in the project using the Administrator app:

<Script name="ChartScript" path="~/plugins/ChartPro/js/chartdialog.js" />

Dear Mr.Mikhail,
The WebSettings.xml had been edited manually, but the result is the same.
I decided to uninstall and reinstall Rapid SCADA. After reinstallation all registration keys are working normally except Chart Pro key. Can not save a configuration on the Web. Always appears the notice” Error saving web application settings: Access to the path is denied.”

Dear mr.Mikhail
I can not get the result. So i decided to reinstall, but i have had a problem with re-installation.
Can i ask you a question?. Will the registration keys be valid if i re-install OS on the same Raspberry Pi4?
Thanks a lot

Dear Mr.Mikhail,
The issue with re-installation Rapid SCADA in Raspberry Pi have been resolved. All registration keys are working perfectly except Chart Pro key too, can not process the charts. Can not save the configuration on Web. But the Chart is processing charts normally. This issue of Chart Pro Plugin is the same with the person on Russia Forum Rapid Scada.
Pls let us know why?
Thanks a lot

If installed on the same paths, the keys will be valid

It is not clear why you do not change your rights forcibly. Yes, there is such an error with the rights, but after adding the chmod command to the server startup file, I no longer had any problems with this error.
Why this does not help you is not at all clear

Dear manjey73,
Thank you for your reply.
The chmod command have been added. You can see a screenshot bellow:

Thanks agian

Change the path depending on where you installed Scada. If installed by default, the path should be
/opt/scada/ScadaWeb/Config

Dear manjey73,
Thank you for your reply.
The path have been changed. My project Scada installed by default. The path is /opt/scada/ScadaWeb/Config

The result was the same: “Error saving web application settings: Access to the path is denied.”
Why????

[manjey73]

Very strange. when the server is restarted, the command is executed from the root user in theory. Perhaps the web user does not have enough rights, but it is already necessary to see what is there with apache2 in the settings. We need to think about it…

[manjey73]

Show access rights to all folders, starting with /opt ?

[manjey73]

Probably the folders above the level do not have the appropriate rights, and it does not even reach the final Config folder. Just doesn’t let it go any higher.

Thanks

on the remote server, I gave the entire scada folder to the system user with ID=1000, that is, this is the user that you create in the system, for example, for Raspberry Pi, this is the pi user. I also added this user to the www-data group just in case.

Change the owner for all folders and files in the folder.

sudo chown -R user:group /path/to/dir/

Where user is the new owner and group is the user group. -R indicates that the rights must be changed recursively.

Example for Raspberry and install in /opt

sudo chown -R pi:pi /opt/scada

Dear Mr.Mikhail,
The WebSettings.xml had been edited manually, but the result is the same.

Hello,
In this case you have no need to save it in the web interface.
