I'm trying to setup continuous deployment pipeline to one of the websites hosted in a Linux machine which has Plesk. A service account(service_user) is already setup there in the server(not a Plesk account though).

My issue is the service account that I mentioned above cannot access the hosting directory(/var/www/vhosts/example.com/). because it is owned by some other user & group(sysuser_9:psaserv)

The permissions details :

Home Directory :

I tried to add the service account to the following groups : psaserv & psacln . but still access denied.

All I need to do is copy the zip file to the hosting directory & extract it. I already messed up the directory permission of the hosting after executing chown for the service account :P . Just recreated the hosting. How do I give access to the service account to read/write to a particular hosting directory?

  • "owned by some other user & group" -- What user and group is it? What are the permissions on the /var/www/vhosts/example.com/ directory and all parent directories? Does it allow group rwx? Do the parent directories allow group rwx? Aug 19, 2021 at 9:16
  • Owned by sysuser_9:psaserv. The permissions what i can see is : rwx r-x ---

The group psaserv doesn't have permission to write to /var/www/vhosts/example.com/. The middle group in the permissions (r-x) are for the group. The group has "read" (r) and "execute" (x) permission, but it missing the "write" (w) permission. To be able to have that group be able to write to that directory, you need to change the permissions:

chmod g+w /var/www/vhosts/example.com/

After running that command, the permissions on that directory would be rwx rwx ---. As long as it has execute permission in each directory above that, a job running in that group would then be able to write to that directory.

  • Exactly!!. i noted another issue, The service account created by the systems team had Uppercase letters. So when I issue the usermod -a -G GROUP USER command I have to specify the USER in lowercase :D. i realized this after checking groups command! because the added groups was not in the list. Then applied proper write permission as Stephen specified above.
