AutoFS and Mounting in Linux\/Redhat\/CentOS<\/p>\n
echo “AutoFS – Automatic FS system Mounting – Dec 26th, 2017 by Sayed”<\/p>\n
check if Autofs installed or not
\nyum list installed | grep autofs<\/p>\n
I just installed; hence it is there
\nyou can install with yum -y install autofs<\/p>\n
944 yum -y install autofs<\/p>\n
then you can enable autofs
\n946 systemctl status autofs
\n947 systemctl start autofs
\n948 systemctl enable autofs<\/p>\n
enable – will start this service at reboot\/system start<\/p>\n
AutoFS in general does not use \/etc\/fstab
\nAutoFS uses \/etc\/mtab file
\nAlso, AutoFS has some files under \/etc and starting with auto. You can also define which file will contain the mounting mapping. the file that will act like \/etc\/fstab for autofs<\/p>\n
AutoFS has direct mapping and indirect mapping
\nlet’s see some files under \/etc for autofs<\/p>\n
955 ls \/etc\/auto*<\/p>\n
The files<\/strong><\/p>\n \/etc\/auto.direct \/etc\/autofs.conf \/etc\/autofs_ldap_auth.conf \/etc\/auto.master \/etc\/auto.misc \/etc\/auto.net \/etc\/auto.smb \/etc\/auto.master.d:<\/p>\n I saw to use \/etc\/auto.master for configuring which file will do the mapping for direct mounting. One more config file is under: \/etc\/sysconfig\/autofs<\/p>\n 961 cat \/etc\/sysconfig\/autofs<\/p>\n the content For mounting NFS i.e. remote\/network file-systems\/folders – we can use the regular mounting i.e. \/etc\/fstab and mount command. However, that is kinda manual. We can mount NFS using AutoFS that will be automatic mount<\/p>\n We use AutoFS for LDAP clients to auto mount Users’ home directories. We just configure, then the mounting happens automatically. You remember that getent passwd user-name mounted the remote users’ home directory into local system. we used \/etc\/auto.master to tell that auto.guests will have the mounting configurations. then on \/etc\/auto.guests file – we configured that users’ home directories will be mounted on \/home\/guests. you can check our notes on LDAP client configuration<\/p>\n 979 cat \/etc\/auto.master we added the following line on \/etc\/auto.master it just tells that AutoFS will consult \/etc\/auto.guests file for direct mapping<\/p>\n <\/p>\n 984 vim \/etc\/auto.guests it just tells remote \/nfsrh will be automatically mounted to \/home\/guests 989 systemctl restart autofs<\/p>\n <\/p>\n Indirect Map AutoFS and Mounting in Linux\/Redhat\/CentOS echo “AutoFS – Automatic FS system Mounting – Dec 26th, 2017 by Sayed” check if Autofs installed or not yum list installed | grep autofs I just installed; hence it is there you can install with yum -y install autofs 944 yum -y install autofs then you can enable autofs … <\/p>\n
\nI saw to use \/etc\/auto.misc for configuring which file will do the mapping for indirect mounting for AutoFS.<\/p>\n
\n#
\n# Init system options
\n#
\n# If the kernel supports using the autofs miscellanous device
\n# and you wish to use it you must set this configuration option
\n# to “yes” otherwise it will not be used.
\n#
\nUSE_MISC_DEVICE=”yes”
\n#
\n# Use OPTIONS to add automount(8) command line options that
\n# will be used when the daemon is started.
\n#
\n#OPTIONS=””
\n#<\/p>\n
\n980 vim \/etc\/auto.master<\/p>\n
\n\/etc\/auto.guests \/etc\/auto.direct<\/p>\n
\nwe added the following line on \/etc\/auto.guests
\n\/home\/guests 192.168.1.15:\/nfsrh<\/p>\n
\nyou can try to restart autofs<\/p>\n
\nindirectly mounted points are only visible when accessed
\nautomatically mounts shares under one common parent directory
\neach indirect map put only one entry in the mtab file
\nlocal and indirect maps cannot exist in the same parent directory
\nfor indirect mapping – you use \/etc\/auto.misc file<\/p>\n","protected":false},"excerpt":{"rendered":"
