The file /etc/fstab doesn't contain 'shm'

Post by yaoyansi » 2016/01/26 08:11:00

Hi all,
I'm modifying /etc/fstab with this guide:https://www.vultr.com/docs/secure-tmp-a ... n-centos-6

It says:

Code: Select all

Look for the line in the fstab file with tmpfs and /shm. Replace 'defaults' with 'defaults,nosuid,noexec,nodev'. Save the file.
But I can't find any 'shm' in my /etc/fstab.
Here is the content of my /etc/fstab

Code: Select all

# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info

/dev/mapper/centos-home /home                   xfs     defaults        1 2
/dev/mapper/centos-swap swap                    swap    defaults        0 0
Is there anything wrong with my file?
Cheers

No, the Guide is for CentOS 6 and you are using CentOS 7, that's the problem. /dev/shm is no longer handled by /etc/fstab in CentOS 7 but by systemd instead.
