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> ---- linux_wiki/auto_mount_network_shares.txt Last modified: 2019/05/25 23:50(external edit)
