- This ansible role aids in the creation of automount files using either the autofs service or the systemd init system. This role works under Enterprise Linux (Red Hat, CentOS, Scientific Linux) and the Fedora environments. To use this role, simply fill out the systemdmounts or autofsmounts variables in your variable list. The mounts are a set.
- Problem: I have CentOS 7 Linux VM with cifs installed. I added a mount point using autofs where the whole idea was to automatically mount a network share every time VM boots. However, when I run this command: ls /mnt/vmshare/trinity I get. Ls: cannot access /mnt/vmshare/trinity: No such file or directory.
- Automount comes in handy (if you don't already have autofs, install it by yum install autofs). Here is what you need to do. First create a mount point root@host# mkdir /mymount Note: You can use any directory; make sure that directory exists To the /etc/auto.master file add a line like: /mymount /etc/auto.mymount.
This is extension of my prevoius article.In this one we will configure client computer (192.168.122.80) to automount folder located on remote computer (192.168.122.90)
AutoFS service is alternative to /etc/fstab mount points.Unlike /etc/fstab method, AutoFS mounts filesystem when user access it and unmount them after a period of inactivity.
Autofs-5.0.7-54.el7.x8664 Yes, autofs is installed. Now go to the next step. Append the master configuration file /etc/auto.master to specify the mount point. Automount NFS share in Linux using autofs On Centos/RHEL 7. NFS share in Linux using autofs. Autofs is a service in Linux like operating system which automatically mounts the file system and remote shares when it is accessed. Main advantage of autofs is that you don't need to mount file system at all time, file system is only mounted when it.
On server side (192.168.122.90) we installed nfs-util package.
We will create folder which will be accessible to remote system
Add this folder to /etc/export file:
How To Configure Autofs
/myfolder is exported to 192.168.122.80 as read-write
Export the entries defined in the /etc/exports file and pass them to to rpc.mountd
(if NFSv2 or NFSv3) for the mounting process, then to rpc.nfsd
where the file systems are made available to remote users.
exportfs command writes filesystems to /var/lib/nfs/etab

Restart nfs service (firewall port was opened in previous article)
Client configuration:
On client (192.168.122.80) install autofs package
By default,autofs configuration file is empty,add followowing entries to /etc/sysconfig/autofs file:
Remote shares must be configured in /etc/auto.master file
# Sample auto.master file
# This is a ‘master' automounter map and it has the following format:
# mount-point [map-type[,format]:]map [options]
# For details of the format look at auto.master(5).
#
/- /etc/auto.direct #add this line to tell autofs service where to look up for mounting entries
/misc /etc/auto.misc
#
# NOTE: mounts done from a hosts map will be mounted with the
# 'nosuid' and 'nodev' options unless the 'suid' and 'dev'
# options are explicitly given.
#
/net -hosts
#
# Include /etc/auto.master.d/*.autofs
# The included files must conform to the format of this file.
#
+dir:/etc/auto.master.d
#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.
#
#+auto.master #comment this line for NFS shares or you'll get 'unable to read auto.master file'
Autofs Centos 7
Create directory named /folder on client.Create /etc/auto.direct file to define our share from 192.168.122.90
Autofs Centos 7 Mount
In local directory (/folder) will be mounted folder from remote machine (192.168.122.90:/myfolder) as read write (rw) as nfs file system
