-====== Auto Mount Network Shares ======
-**General Information**
-Automatically mounting network shares with autofs. This is the client configuration and assumes a working server setup with NFS or CIFS shares already.
-**Checklist**
-  * Distro(s): Enterprise Linux 6/7
-  * Other: Network server with shared directory (NFS or CIFS)
-----
-====== Install Required Packages ======
-**Pre-reqs:**
-  * Assuming that all client/server regular nfs/cifs mounting works before continuing. See below for configuration.
-    * [[linux_wiki:nfs_shares|NFS Shares]]
-    * [[linux_wiki:cifs_windows_shares|CIFS Shares]]
-\\
-Install autofs
-<code bash>
-yum install autofs
-</code>
-----
-====== Autofs Config ======
-===== Map Files =====
-The master map file contains entries that point to other config files for specific mount instructions.
-  * EL6: /etc/auto.master
-  * EL7: /etc/auto.master.d/<name>.autofs
-    * In EL7, the "/etc/auto.master" file is part of the RPM; any updates to the autofs package could overwrite changes you make, so it is recommended to create your own master map file under /etc/auto.master.d/. The name does not matter, as long as it ends in ".autofs"
-\\
-Master Map File Contents
-  * First column = name of the mount point on the local client system
-  * Second column = config file that controls its mounting
-  * Third column (optional) = default mount options for all mounts defined in config file
-Example
-<code bash>
-# File: /etc/auto.master OR /etc/auto.master.d/<name>.autofs
-# Direct mounts: look in auto.direct for mappings
-/-     /etc/auto.direct
-# Indirect mounts: look in auto.home for mappings of subdirectories of /home/
-/home  /etc/auto.home --timeout=600
-</code>
-  * Direct Maps => One or more full path mounts to one or more remote servers. This is similar to regular NFS mounts that you would see in /etc/fstab.
-    * Above example: /-     /etc/auto.direct
-  * Indirect Maps => Directories on the remote server that can all be mounted under the same local mount point. (IE: All sub directories of the listed local mount "/home")
-    * Above example: /home  /etc/auto.home --timeout=600
-----
-==== Direct Map Example ====
-**Note:** All direct map entries must be defined as "/-" in the /etc/auto.master or /etc/auto.master.d/<name>.autofs file.
-<code bash>
-# File: /etc/auto.direct
-# Reminder of master map contents for reference:
-#   /-     /etc/auto.direct
-# Direct mappings: local mountpoint from remote mountpoint
-/network-shares/nfs-share    -rw    192.168.1.151:/data/nfs
-/network-shares/nfs-share2   -rw    192.168.1.151:/data/nfs2
-/network-shares/cifs  -fstype=cifs,rw,credentials=/root/.ssh/.cifs-share  ://192.168.1.151/cifs-share
-</code>
-  * First column => local mount point
-  * Second column => mount options
-  * Third column => remote shared directory
-----
-==== Indirect Map Example ====
-**Note:** This example works best when implemented using LDAP authentication to ensure that user id's are matched up between NFS server and clients.
-Naming local and remote directories
-<code bash>
-# File: /etc/auto.home
-# Reminder of master map contents for reference:
-#   /home  /etc/auto.home --timeout=600
-# Indirect mappings: sub directories of /home/
-yoda    192.168.1.151:/home/yoda
-luke    192.168.1.151:/home/luke
-vader   192.168.1.200:/home/vader
-</code>
-\\
-Naming local only (Ampersand Wildcard)
-<code bash>
-yoda    192.168.1.151:/home/&
-</code>
-  * The "&" is replaced by the key in the first column (yoda)
-\\
-All wild cards (Asterisk and Ampersand Wildcards)
-<code bash>
-*    192.168.1.151:/home/&
-</code>
-  * "*" is assigned the directory that is accessed. If someone tried to access "/home/yoda", the "*" value is "yoda".
-  * The "&" in the remote server line is replaced by the key in the first column (*). So if someone accesses local "/home/yoda", the remote system (192.168.1.151) gets an access attempt to "/home/yoda"
-----
-===== Start and Enable =====
-Start and Enable Auto Mounter on Boot
-  * EL7<code bash>systemctl start autofs
-systemctl enable autofs</code>
-  * EL6<code bash>service autofs start
-chkconfig autofs on</code>
-Reload Auto Mount Config (to enable changes made after service startup)
-  * EL7<code bash>systemctl reload autofs</code>
-  * EL6<code bash>service autofs reload</code>
