Hello! Im trying to create a screen folder for the user apache, Not root. But it seems to fail, I have no idea on how to fix this issue. I only get the error: Cannot make directory ‘/var/run/screen/S-apache’: Permission denied
Im using Cent OS 7
There may be various possible reasons.
2 common reasons:
screen is not installed correctly.
You may try using another non-root user to verify whether
screen is installed and works correctly. It makes use of the
setgid permission and these file/dir permissions should usually be as follows.
screen binary’s group should be ‘screen’ and
screen should have the ‘-s-‘ flag:
$ getfacl $(which screen) getfacl: Removing leading '/' from absolute path names # file: usr/bin/screen # owner: root # group: screen # flags: -s- user::rwx group::r-x other::r-x
/var/run/screen dir group is ‘screen’:
$ ls -lha /var/run/ | grep screen drwxrwxr-x 3 root screen 60 Aug 28 18:59 screen
If there are not like this, you may manually set them or re-install
Check the log after you tried
screen by user ‘apache’:
# tail /var/log/audit/audit.log
and see whether it shows some messages related. If so, relax SELinux for the permissions.
