linux服务器设置自动挂载目录

1：配置/etc/exports文件

把需要共享的文件系统直接编辑到/etc/exports文件中，这样当NFS服务器重新启动时系统就会自动读取/etc/exports文件，从而告诉内核要输出的文件系统和相关的存取权限。如在server2的/etc/exports:

/var/spool/test1    server1(rw) server2(rw)
/var/spool/test2    server1(rw) server2(rw)
/var/spool/test3    server1(rw) server2(rw)

2：autofs的主要配置文件有两个，分别是/etc下的auto.master和auto.misc。其中，auto.master是起控制作用的，它定义了挂在点和automount动作的文件。其内容如下：

# $Id: auto.master,v 1.4 2005/01/04 14:36:54 raven Exp $## Sample auto.master file# This is an automounter map and it has the following format# key [ -mount-options-separated-by-comma ] location# For details of the format look at autofs(5).#/misc  /etc/auto.misc         #/misc是定义的自动mount的挂载点，/etc/auto.misc里定义了mount的动作/home  /etc/auto.home         #/home是定义的自动mount的挂载点；/etc/auto.home定义了mount的动作，                                  #此文件系统默认不存在，需要我们手工创建。/net   -hosts## Include central master map if it can be found using# nsswitch sources.## Note that if there are entries for /net or /misc (as# above) in the included master map any keys that are the# same will not be seen as the first read key seen takes# precedence.#+auto.master

/etc/auto.misc的内容如下：

## $Id: auto.misc,v 1.2 2003/09/29 08:22:35 raven Exp $## 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) manpagecd              -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom         #将/dev/cdrom自动挂载到/misc/cd/下# the following entries are samples to pique your imagination#linux          -ro,soft,intr           ftp.example.org:/pub/linux  #将ftp.example.org的共享目录                                                                            #/pub/linux/自动挂载到/misc/linux/下#boot           -fstype=ext2            :/dev/hda1         #将本地磁盘分区/dev/hda1自动挂载到/misc/boot下#floppy         -fstype=auto            :/dev/fd0          #将软盘设备/dev/fd0自动挂载到/misc/floppy下#floppy         -fstype=ext2            :/dev/fd0#e2floppy       -fstype=ext2            :/dev/fd0#jaz            -fstype=ext2            :/dev/sdc1#removable      -fstype=ext2            :/dev/hdd

在server1的/etc/auto.misc文件中添加如下设置：

test1        -fstype=nfs,rw,nolock         server2:/var/spool/test1
test2        -fstype=nfs,rw,nolock         server2:/var/spool/test2
test3        -fstype=nfs,rw,nolock         server2:/var/spool/test3

保存后，cd /misc/test1 

server1就可以访问server2的共享目录了。
