AutoFS Automatic Mount Service

Requirement: Make the following two commands automatic mount

172.16.2.6:/share/soft/share/soft

172.16.2.6:/share/iso/share/iso

Client:

1.yum-y Install AutoFS

2, # Mkdir/share (Mount point)

3. # Vim/etc/auto.master

/share/etc/auto.share--This file does not exist later, the custom name

4. # Vim/etc/auto.share

Soft-172.16.2.6:/share/soft

Iso-172.16.2.6:/share/iso

5, #/etc/init.d/autofs Restart --Restart service

Attention:

--mount the directory by default in the/share directory with the LS command can not be seen, but may cd/share/iso in, this will help you automatically mount

After about five minutes, if not used, will automatically umount off

The primary configuration file is in/etc/auto.master, where the format is:

Mount Directory Map File parameters

/share/etc/auto.share--timeout=60

Mount a directory, that is, where is it mounted?/mnt or otherwise, this is specified by default/share

Mapping file, AutoFS is how to find the mounted device where? The above mount Directory is just a general directory, CDROM,FLOPPY,NFS,SMBFS files are attached to a/share, then how to divide the clear? So the AOTUFS program will automatically generate a mount point directory in the Mount directory, where the mapping file specifies the directory name, the mapping file format (here is:/etc/auto.share file content):

Sub-directory name mount option mount device

Soft-fstype=iso9660,ro:/dev/cdrom #注意冒号

Iso-fstype=auto:/dev/floppy

The mounted device can be a network path, for example 192.168.100.195:/opt/wwwroot

PS: A writing example of a map file

To mount the configuration of samba:

BACKUP-FSTYPE=CIFS,USERNAME=SMBUSER1%ASDF://192.168.1.99/pub

To mount the ISO configuration:

Iso-loop,fstype=iso9660,ro:/root/rhel-server-6.0-x86_64-boot.iso

Mount NFS Configuration:

Nfs-fstype=nfs 192.168.1.99:/test_nfs

Server: NFS Portmap (rhel6 to be called rpcbind), build see NFS Servers detailed configuration

1. # showmount-e 172.16.2.6

Clnt_create:RPC:Port Mapper failure-unable Toreceive:errno 111 (Connection refused)

2. #/etc/init.d/rpcbind start (Start Rpcbind to start NFS service)

3, #/etc/init.d/nfs Restart--restart NFS, register the new RPC

4, # showmount-e172.16.2.6--Again OK

Server for NFS configuration file: Vim/etc/exports

Parameters:

RO Read Only

RW Readable and writable

Root_squash on behalf of the client to Nfsnobody user mount, default does not write

No_root_squash on behalf of the client with root user mount

Sync synchronization

Async Async

Master configuration file: Vim/etc/exports

/share/iso * (RO)--Share the/share/iso to * (on behalf of all IP) RO (for Read only)

/share/iso * (rw)--RW representative readable writable

/share/iso 10.1.1.0/24 (RO)--computer access only for network segments shared with 10.1.1

/share/iso 10.1.1.0/255.255.255.0 (RO)

/share/iso 10.1.1.218/255.255.255.255 (RO)--Define only 10.1.1.218 this machine can access

/share/iso 10.1.1.218 (RO)

/share/iso 10.1.1.218/32 (RO) 10.1.1.254/32 (rw)--Define only 218 and 254 these two can be accessed

About NFS Permissions:

The permissions of the client mount directory to the server-side shared directory

The default permission for the NFS service shared directory is to mount the Nfsnobody user.

There's a sentence under the/etc/passwd.

Nfsnobody:x:65534:65534:anonymous Nfsuser:/var/lib/nfs:/sbin/nologin

Note: If the service is done, the permissions of the service and the permissions of the system are combined to take effect:

That is, the client can access, requires firewall permission, the service allows, system permissions allow, to access
