Command for disabling this cron checker: "cldiag --disable-cron-checkers check-hidepid"

Environment

• CloudLinux

Solution

1. To disable hidepid, add the following to the /etc/fstab:

proc /proc proc defaults,hidepid=0,gid=0 0 0

2. Or you can specify the desired hidepid and gid values explicitly:

proc /proc proc defaults,hidepid=2,gid=clsupergid 0 0

3. You should execute the following:

mount -o remount /proc

4. In some cases it is necessary to remount fully manually:

mount -o remount,defaults,hidepid=2,gid=clsupergid /proc
