[Resolved] LSCache issue when disabling user

[Danielle M.]

Hey all,

I'm currently running into an issue on one of my servers where I get the following error when disabling LSCache for a user:

/home/username/public_html - Could not open input file: /usr/local/lsws/add-ons/webcachemgr/shared/lscwp_interact.php

As a note, this is a WHM/cPanel server.

I tried updating to the latest version of LiteSpeed AND LSCache but doing neither worked.

Any advice?

It could be permission problem. check if root user can access that file. if yes, check a regular user see if can access, if not, it is a permission problem.
Also, if you use CageFS, perform a force update to make sure that file is available in the user's cage.

Hi Danielle,

That script should only be accessed through WHM as root. Are you logged in as root when trying to disable?

If so and you are still having issue please pm me with WHM and ssh login details and I will look into it.

Regards,
-Michael

Hey guys,

I tried running:

cagefsctl --force-update
cagefsctl --remount-all

But the problem persists. I am in WHM as root disabling LSCache for the users. Here is the output of stat for the file in question. As you can see, file permissions and ownership look correct.

root@server [~]# stat /usr/local/lsws/add-ons/webcachemgr/shared/lscwp_interact.php

Michael, I feel uncomfortable sharing server information since hundreds of clients reside on it. If there are any other suggestions you may have or information you need, please let me know as I'd like to try that route first.

Thank you!
Dani

/home/username/public_html - Could not open input file: /usr/local/lsws/add-ons/webcachemgr/shared/lscwp_interact.php

maybe a open_basedir issue ?
please refer

disable open_basedir for "username", see if any difference.

Thanks for the reply, but that still didn't work. Does anyone have any other ideas? This is a core LSCache function and my setup didn't change from when I last enabled everything, so I don't see how disabling has become an issue.

Is there an SSH command equivalent to clicking 'Disable' on the 'Manage Cache Installations' area of LSCache?

HI Danielle,

If enable was working previously with no changes then there really isn't any reason that disable should be running into problems as they use the same script.

You can try the following command as root directly to see if it works, where $user is the WordPress site owner, '.../lsws/' is replaced by the path to lsws, and $fullPathToWPDir is the path to your wordpress installation files (should contain wp-admin folder).

su $user -s /bin/bash -c "php -d disable_functions= .../lsws/add-ons/webcachemgr/shared/lscwp_interact.php disable $fullPathToWPDir"

Michael,

Thanks so much for the reply. With that, I get the following error:

Could not open input file: disable

Is there any way I can replace the file that's seemingly causing me problems (/usr/local/lsws/add-ons/webcachemgr/shared/lscwp_interact.php)? Or are there any other lsws files I can/should safely replace with new ones to try and fix this without interrupting site access on the server? I think that's the next step, considering nothing else has worked.

 

[Michael A]

There should be a space after 'disable_functions=' before entering in the path, the error message looks like you missed that. As for replacing the file, it is added when the server is installed, you can try force reinstalling the server through our WHM plugin if the previous method still does not work.

Michael,

Duh, sorry about that mistake. Looks like when run properly the bash command gives the same error as the PHP interface:

Could not open input file: /usr/local/lsws/add-ons/webcachemgr/shared/lscwp_interact.php

I suppose I'll try reinstalling if I can't figure out anything else.

 

[Michael A]

Good luck. You can PM me any time if your still running into issues and we can try to figure this out.

Regards,
-Michael

For anyone who is curious,

It turned out that the path to LiteSpeed Web Server was not made available through cageFS properly, preventing lscwp_interact from being run as the WordPress owner.

This can be fixed by running the following commands as root:

echo "/usr/local/lsws" >> /etc/cagefs/cagefs.mp
cagefsctl --remount-all

Regards,
-Michael
