Resolved chroot: permission denied

[cyrillvw]

Hello

We a few onyx servers and would like to enable chroot. It works on most servers, but there is one (exactly the same version as the others) that we only get:

execv("/bin/bash") failed
system error: Permission denied

We allready tried the following solution: https://support.plesk.com/hc/en-us/...is-not-working-system-error-Permission-denied
it does not fix anything.

What can we do, this is quite annoying?

Have you tried

# plesk repair fs

?

 

[cyrillvw]

Yes i tried this. Also the bootstrapper and even compared permissions on working servers. Did not change anything still permission denied

 

[IgorG]

Are you sure that you have correct permissions here:

# ls -la /var/www/vhosts/chroot/lib64/ld-linux*
-rwxr-xr-x 1 root root 155464 Dec 7 04:03 /var/www/vhosts/chroot/lib64/ld-linux-x86-64.so.2

# ls -la /var/www/vhosts/chroot/lib/ld-linux*
-rwxr-xr-x 1 root root 150960 Dec 7 03:29 /var/www/vhosts/chroot/lib/ld-linux.so.2

Yes, the permissions are exactly as you describe, still permission denied

Output of

# getenforce

?

 

[cyrillvw]

Disabled

Hmm... I can only recommend to create a request to Plesk support team to do in-depth investigation to find the reason and to fix it directly on your server.

The thing here is that we only have a support-code and with your new ticketing system its impossible to open a new request since we cannot access the email linked with it

 

[IgorG]

What about this method #15 ?

 

[cyrillvw]

We are actually partners so this would be a bit too much paying. I opened a reqest now with my operator email so i hope it will be approved.

We resolved the issue, just for anyone wondering what it was:

the filesystem for /var/www was mounted with the "noexec"-flag which does not allow execution of files on it. After a remount whitout this flag, everything works as it should.
