This file should contain a separate line for each NFS share. Now, we will create the file which contains our automounter map. autofs /etc/auto.nfs -timeout=60 Create /etc/auto.nfs Note: It is optional to define the timeout in /etc/auto.master file. After five minutes of inactivity, a filesystem that is mounted will be automatically unmounted. The default timeout for autofs is 300 seconds (5 minutes). # CentOS 7 / RHEL 7 & Fedora 27/26 #Īdd the following line at the end of /etc/auto.master file. The following step creates a mount point at /autofs and configures it according to the settings specified in /etc/auto.nfs (which we will create in the next step). # same will not be seen as the first read key seen takesĪs per our scenario, we are going to mount NFS share on /autofs/nfsfileshare using Autofs. # above) in the included master map any keys that are the # Note that if there are entries for /net or /misc (as # Include central master map if it can be found using # The included files must conform to the format of this file. # "nosuid" and "nodev" options unless the "suid" and "dev" # NOTE: mounts done from a hosts map will be mounted with the # For details of the format look at auto.master(5). # This is a 'master' automounter map and it has the following format: Sample output of /etc/auto.master, you can see the mount and its map shown in “ Green“. The master map file contains a list of mounts and the location of its map. The main configuration file for Autofs is the /etc/auto.master file, referred as the master map. $ sudo apt-get install autofs Configure Autofs Install it using the following command on terminal. ![]() Let’s install autofs package available from the base repository. READ: How to setup NFS Server on Debian 9 / Ubuntu 16.04 Install Autofs READ: How to setup NFS Server on CentOS 7 / RHEL 7 / Fedora 27 NFS Client Hostname: (CentOS 7 / Fedora 27 / Ubuntu 16.04)Īutofs mount path: /autofs/nfsfileshare Prerequisites NFS Server Hostname: (CentOS 7 / Fedora 27 / Ubuntu 16.04) Here are my demo nodes detail, I have both NFS and Client server in the same distribution. The same steps will apply to previous versions of CentOS, Fedora, Ubuntu, and Debian. This guide helps you to install and configure Autofs on CentOS 7 / Fedora 27 / Ubuntu 16.04 / Debian 9. Because of this, automounting NFS/Samba shares conserves bandwidth and offers better overall performance compared to static mounts via fstab.Īutofs can also be used to mount other file systems including AFS, SMBFS, CIFS, and local file systems. Autofs solves the problem of keeping the filesystem mounted that are not frequently accessed by the users by unmounting it after a period of inactivity. When the static mount (/etc/fstab) is used, regardless of how infrequently a user accesses the NFS mounted file system, the system must dedicate resources to keep the mounted file system in place. In the last tutorial we used /etc/fstab to mount a filesystem automatically across the system reboot, but here we will use autofs to mount the same NFS share.ĪutoFS very useful in case if the client machine has to mount many mounts at one time, overall boot up time will be increased with the autofs we can speed up the bootup time. Auto-mounts are mounted only when they are accessed and are unmounted after a period of inactivity. Autofs is an automounter utility that helps you to automatically mount NFS share when a file or directory is requested on the NFS mount point.
