一、基于Linux下NFS文件系统的自动挂载方式，
前期准备环境两台Linux服务器:
准备一台NFS服务器端（系统环境centos6.5,ip地址192.168.100.100）
准备需要挂载NFS服务端的NFS客户端(系统环境centos6.5,ip地址192.168.100.101)
实施：
现在server端安装NFS保证能正常访问，我们这里通过yum工具安装即可
[root@nfsserver ~]# yum install nfs-utils rpcbind -y
通过修改NFS配置，共享/data/share/目录
[root@nfsserver ~]# mkdir /data/share
[root@nfsserver ~]# vim /etc/exports
##########shared data for bbs by oldboy at 20160825
#/data/share 192.168.100.0/24(rw,sync,hide)
/data/share 192.168.100.0/24(rw,sync,anonuid=555,anongid=555,all_squash)
检查NFS是否正常
[root@nfsserver ~]# showmount -e 192.168.100.100
Export list for 192.168.100.100:
/data/share 192.168.100.0/24
客户端安装NFS客户端及autofs并启动相关服务
[root@nfsclient ~]# yum install rpcbind nfs-utils -y
[root@nfsclient ~]# yum install autofs -y
[root@nfsclient ~]# /etc/init.d/rpcbind start
[root@nfsclient ~]# /etc/init.d/autofs start
配置客户端自动挂载（autofs）NFS服务端共享目录
[root@nfsclient ~]# vim /etc/auto.master
#
# 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).
#
/misc /etc/auto.misc
/mnt /etc/auto.misc timeout=60#/mnt为挂载点 /etc/auto.misc为挂载动作
[root@nfsclient ~]# vim /etc/auto.misc
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# Details may be found in the autofs(5) manpage
cd -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom
# the following entries are samples to pique your imagination
#linux -ro,soft,intr ftp.example.org:/pub/linux
#boot -fstype=ext2 :/dev/hda1
#floppy -fstype=auto :/dev/fd0
#floppy -fstype=ext2 :/dev/fd0
#e2floppy -fstype=ext2 :/dev/fd0
#jaz -fstype=ext2 :/dev/sdc1
#removable -fstype=ext2 :/dev/hdd
nfsdata -fstype=nfs 192.168.100.100:/data/share
6.重新启动autofs服务，并检查自动挂载文件是否生效
[root@nfsclient ~]# /etc/init.d/autofs restart
[root@nfsclient ~]# cd /mnt/nfsdata
[root@nfsclient nfsdata]# ls -l
