autofs设置完毕后，如果往挂载点写数据，总是会提示权限不够；
问题详细描述：
1、进入挂载点之后，只显示的是auto.master中设置的挂载点，里面没有NFS上所设置的挂载目录中的内容；
2、通过touch命令无法在该挂载点中写入数据，有如下提示：
[root@autofs ~]# cd /
[root@autofs /]# ls
autofs_mount cgroup etc lib64 misc opt sbin sys var
bin data home lost+found mnt proc selinux tmp
boot dev lib media net root srv usr
[root@autofs /]# cd misc/
[root@autofs misc]# ls
test1
[root@autofs misc]# cd test1/
[root@autofs test1]# ls
[root@autofs test1]# mkdir skdjf
mkdir: 无法创建目录"skdjf": 权限不够
[root@autofs test1]# touch sldjf
touch: 无法创建"sldjf": 权限不够
[root@autofs test1]#
3、配置过程
配置auto.master
/misc/test1 /etc/auto.misc
配置auto.misc
test1 -fstype=nfs,rw,soft,intr 192.168.0.122:/home/nfs_test/test1
4、在auto.master的配置过程中，也试过配置auto.nfs的方式，同样不管用，报同样的错误；
5、分析
通过执行结果可以看出，配置完毕之后auto.master文件肯定是起作用了的，因为启动服务后就生成了文件配置中对应的目录了，但是进入该目录后没有看到NFS挂载目录的文件，同时也不能往该目录中写入数据，因此怀疑，生成的这个目录只是作为一个挂载点，还没挂载nfs目录，类似与这个挂载点现在是一个文件，一个只读文件，无法写入数据，因此怀疑auto.master文件中所写的不管是auto.misc还是auto.nfs，这种文件都没有起作用，那么是不是缺少一个动作去挂载这个目录呢，是否还缺少一个服务或者一个脚本需要执行一下呢？
6、问题解决
----------------------------------------------------------------------------------------------------------------------------------------------
autofs+nfs配置过程
环境:
Centos6.5_X86_64
server:192.168.0.122
client:192.168.0.104
1、建立NFS：
[root@nis-server1 /]# vim /etc/exports
#/rhome 192.168.0.0/24(rw,no_root_squash)
#/cluster 192.168.0.0/24(rw,no_root_squash)
#/tmp/test 192.168.0.0/24(rw,no_root_squash)
#/home/nfs_test/tmp 192.168.0.0/24(rw,no_root_squash)
#/home/nfs_test/test3 192.168.0.0/24(rw,no_root_squash)
#/home/nfs_test/nfs 192.168.0.0/24(ro) *(ro,all_squash)
#/home/nfs_test/upload 192.168.0.0/24(rw,all_squash,anonuid=210,anongid=210)
#/home/nfs_test/andy 192.168.0.0/24(rw)
#/home/nfs_test/test2 192.168.0.0/24(rw,no_root_squash)
#/home/nfs_test/test1 192.168.0.0/24(rw,no_root_squash)
/home/nfs_test/test1 192.168.0.0/24(rw,no_root_squash)
2、开启NFS服务：
[root@nis-server1 /]# service nfs restart
关闭 NFS 守护进程： [确定]
关闭 NFS mountd： [确定]
关闭 NFS quotas： [确定]
关闭 NFS 服务： [确定]
Shutting down RPC idmapd: [确定]
启动 NFS 服务： [确定]
关掉 NFS 配额： [确定]
启动 NFS mountd： [确定]
启动 NFS 守护进程： [确定]
正在启动 RPC idmapd： [确定]
[root@nis-server1 /]#
3、查看是否设置成功：
[root@nis-server1 /]# showmount -e localhost
Export list for localhost:
/home/nfs_test/test1 192.168.0.0/24
[root@nis-server1 /]#
4、配置auto.master
[root@autofs /]# vim /etc/auto.master
#
#/misc /etc/auto.misc
#/misc/test1 /etc/auto.misc
#
# NOTE: mounts done from a hosts map will be mounted with the
# "nosuid" and "nodev" options unless the "suid" and "dev"
# options are explicitly given.
#
/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 mount test
#/rhome /etc/auto.nfs
#/nfs_test /etc/auto.nfs
#/autofs_mount /etc/auto.nfs
#/rhome /etc/auto.nfs
#
/lilong /etc/auto.nfs
5、建立auto.nfs并设置
[root@autofs /]# vim /etc/auto.nfs
#rhome -rw,bg,soft,rsize=32768,wsize=32768 192.168.0.122:/rhome
#nfs_test -rw,bg,soft,rsize=32768,wsize=32768 192.168.0.122:/tmp/test
#test1 -fstype=nfs,rw 192.168.0.122:/home/nfs_test/test1
#* -rw,soft,intr 192.168.0.122:/home/nfs_test/test1/&
#
testing 192.168.0.122:/home/nfs_test/test1
~
6、重启auto.nfs服务
[root@autofs /]# service autofs restart
停止 automount： [确定]
正在启动 automount： [确定]
[root@autofs /]#
7、查看当前挂载状态
[root@autofs /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 40G 9.9G 28G 27% /
tmpfs 932M 76K 932M 1% /dev/shm
/dev/sda1 52G 180M 49G 1% /data
[root@autofs /]#
8、进入挂载点并查看挂载点内容
[root@autofs /]# cd lilong/
[root@autofs lilong]# ls
[root@autofs lilong]#
9、进入auto.nfs设置的挂载点次目录并查看次目录中的内容
[root@autofs lilong]# cd testing
[root@autofs testing]# ls
lsj slkdjf
[root@autofs testing]#
10、查看系统挂载信息
[root@autofs testing]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 40G 9.9G 28G 27% /
tmpfs 932M 76K 932M 1% /dev/shm
/dev/sda1 52G 180M 49G 1% /data
192.168.0.122:/home/nfs_test/test1 40G 9.9G 28G 27% /lilong/testing
[root@autofs testing]#
重新整理NIS+NFS+AUTOFS
--------------------------------------------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------------------------------------------
1、设置域名与启动端口号
[root@nis-server1 /]# vim /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=nis-server1
NISDOMAIN=ocean-peak
YPSERV_ARGS="-p 1011"
2、配置/etc/ypserv.conf
[root@nis-server1 /]# vim /etc/ypserv.conf
# The following, when uncommented, will give you shadow like passwords.
# Note that it will not work if you have slave NIS servers in your
# network that do not run the same server as you.
# Host : Domain : Map : Security
#
# * : * : passwd.byname : port
# * : * : passwd.byuid : port
# Not everybody should see the shadow passwords, not secure, since
# under MSDOG everbody is root and can access ports < 1024 !!!
* : * : shadow.byname : port
* : * : passwd.adjunct.byname : port
# If you comment out the next rule, ypserv and rpc.ypxfrd will
# look for YP_SECURE and YP_AUTHDES in the maps. This will make
# the security check a little bit slower, but you only have to
# change the keys on the master server, not the configuration files
# on each NIS server.
# If you have maps with YP_SECURE or YP_AUTHDES, you should create
# a rule for them above, that‘s much faster.
* : * : * : none
3、查看本机IP，更改/etc/hosts
[root@nis-server1 /]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.106 nis-server1
4、固定yppasswd服务启动的端口号
[root@nis-server1 /]# vim /etc/sysconfig/yppasswdd
# The passwd and shadow files are located under the specified
# directory path. rpc.yppasswdd will use these files, not /etc/passwd
# and /etc/shadow.
#ETCDIR=/etc
# This options tells rpc.yppasswdd to use a different source file
# instead of /etc/passwd
# You can‘t mix usage of this with ETCDIR
#PASSWDFILE=/etc/passwd
# This options tells rpc.yppasswdd to use a different source file
# instead of /etc/passwd.
# You can‘t mix usage of this with ETCDIR
#SHADOWFILE=/etc/shadow
# Additional arguments passed to yppasswd
YPPASSWDD_ARGS="-p 1012"
5、启动NIS相关服务
[root@nis-server1 /]# service ypserv start
设置 NIS 域名 ocean-peak： [确定]
启动 YP 服务器的服务： [确定]
[root@nis-server1 /]# service yppasswdd start
启动 YP 口令服务： [确定]
[root@nis-server1 /]# chkconfig ypserv on
[root@nis-server1 /]# chkconfig yppasswdd on
[root@nis-server1 /]#
6、检查服务启动结果
[root@nis-server1 /]# rpcinfo -p localhost
program vers proto port service
100000 4 tcp 111 portmapper
100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper
100000 4 udp 111 portmapper
100000 3 udp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 33941 status
100024 1 tcp 47918 status
100004 2 udp 1011 ypserv
100004 1 udp 1011 ypserv
100004 2 tcp 1011 ypserv
100004 1 tcp 1011 ypserv
100009 1 udp 614 yppasswdd
[root@nis-server1 /]# rpcinfo -u localhost ypserv
program 100004 version 1 ready and waiting
program 100004 version 2 ready and waiting
[root@nis-server1 /]#
7、建立NIS用户
[root@nis-server1 /]# useradd -u 1001 nisuser1
[root@nis-server1 /]# useradd -u 1002 nisuser2
8、更改NIS用户密码
[root@nis-server1 /]# echo password |passwd --stdin nisuser1
更改用户 nisuser1 的密码 。
passwd： 所有的身份验证令牌已经成功更新。
[root@nis-server1 /]# echo password |passwd --stdin nisuser2
更改用户 nisuser2 的密码 。
passwd： 所有的身份验证令牌已经成功更新。
[root@nis-server1 /]#
9、数据库生成用户信息
[root@nis-server1 /]# /usr/lib64/yp/ypinit -m
At this point, we have to construct a list of the hosts which will run NIS
servers. nis-server1 is in the list of NIS server hosts. Please continue to add
the names for the other hosts, one per line. When you are done with the
list, type a <control D>.
next host to add: nis-server1
next host to add:
The current list of NIS servers looks like this:
nis-server1
Is this correct? [y/n: y]
We need a few minutes to build the databases...

nis-server1 has been set up as a NIS master server.
Now you can run ypinit -s nis-server1 on all slave server.
[root@nis-server1 /]#
10、设置NFS用户目录，并增加用户设置密码
[root@nis-server1 /]# mkdir rhome
[root@nis-server1 /]# useradd -u 1003 -d /rhome/nisuser-nfs-1 nisuser-nfs1
[root@nis-server1 /]# useradd -u 1004 -d /rhome/nisuser-nfs-2 nisuser-nfs2
[root@nis-server1 /]# echo password|passwd --stdin nisuser-nfs1
更改用户 nisuser-nfs1 的密码 。
passwd： 所有的身份验证令牌已经成功更新。
[root@nis-server1 /]# echo password|passwd --stdin nisuser-nfs2
更改用户 nisuser-nfs2 的密码 。
passwd： 所有的身份验证令牌已经成功更新。
[root@nis-server1 /]#
11、更新数据库
[root@nis-server1 /]# /usr/lib64/yp/ypinit -m
At this point, we have to construct a list of the hosts which will run NIS
servers. nis-server1 is in the list of NIS server hosts. Please continue to add
the names for the other hosts, one per line. When you are done with the
list, type a <control D>.
next host to add: nis-server1
next host to add:

nis-server1 has been set up as a NIS master server.
Now you can run ypinit -s nis-server1 on all slave server.
[root@nis-server1 /]#
12、重启服务
[root@nis-server1 /]# service ypserv restart
停止 YP 服务器的服务： [确定]
启动 YP 服务器的服务： [确定]
[root@nis-server1 /]# service yppasswdd restart
停止 YP 口令服务： [确定]
启动 YP 口令服务： [确定]
[root@nis-server1 /]#
13、设置/etc/export
[root@nis-server1 /]# vim /etc/exports
/rhome 192.168.0.0(rw,no_root_squash)
14、重启NFS服务
[root@nis-server1 /]# service nfs restart
关闭 NFS 守护进程： [失败]
关闭 NFS mountd： [失败]
关闭 NFS quotas： [失败]
Shutting down RPC idmapd: [失败]
启动 NFS 服务： [确定]
关掉 NFS 配额： [确定]
启动 NFS mountd： [确定]
启动 NFS 守护进程： [确定]
正在启动 RPC idmapd： [确定]
[root@nis-server1 /]#
15、本地查看NFS是否设置成功
[root@nis-server1 /]# showmount -e localhost
Export list for localhost:
/rhome 192.168.0.0
[root@nis-server1 /]#
16、在客户机查看server NFS信息
[root@nis-client1 桌面]# hostname
nis-client1
[root@nis-client1 桌面]# showmount -e 192.168.0.106
Export list for 192.168.0.106:
/rhome 192.168.0.0
[root@nis-client1 桌面]#
为配合NIS使用，现将export内容改为如下：
/rhome/nisuser-nfs-1 192.168.0.0/24(rw,no_root_squash)
/rhome/nisuser-nfs-2 192.168.0.0/24(rw,no_root_squash)
17、设置auto.master
[root@nis-client1 桌面]# vim /etc/auto.master
# 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
#
# NOTE: mounts done from a hosts map will be mounted with the
# "nosuid" and "nodev" options unless the "suid" and "dev"
# options are explicitly given.
#
/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.
#
#automount 192.168.0.106(nis users)
/rhome /etc/auto.nfs
#
18、设置auto.nfs
[root@nis-client1 桌面]# vim /etc/auto.nfs
rhome 192.168.0.106:/rhome
为配合NIS用户，现将auto.nfs配置更改为如下：
nisuser-nfs-1 192.168.0.106:/rhome/nisuser-nfs-1
nisuser-nfs-2 192.168.0.106:/rhome/nisuser-nfs-2
19、启动autofs服务
[root@nis-client1 桌面]# service autofs restart
停止 automount： [确定]
正在启动 automount： [确定]
[root@nis-client1 桌面]#
20、开启并配置NIS
[root@nis-client1 桌面]# setup
选择验证配置，并运行；
21、选中NIS，并执行下一步：
22、填写域名和服务器IP，并确定：
23、自动启动服务并绑定NIS服务；
24、退出：
25、查看设置的NIS用户名（server端）
[root@nis-server1 桌面]# cat /etc/passwd

用户为nisuser-nfs1和nis-nfs2
26、注销系统，使用NIS用户登录客户机：
[nisuser-nfs1@nis-client1 桌面]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 40G 9.8G 28G 27% /
tmpfs 932M 168K 932M 1% /dev/shm
/dev/sda1 52G 180M 49G 1% /data
192.168.0.106:/rhome/nisuser-nfs-1 40G 9.9G 28G 27% /rhome/nisuser-nfs-1
[nisuser-nfs1@nis-client1 桌面]$
27、注销系统，使用nisuser-nfs2登录：
[nisuser-nfs2@nis-client1 桌面]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 40G 9.8G 28G 27% /
tmpfs 932M 244K 932M 1% /dev/shm
/dev/sda1 52G 180M 49G 1% /data
192.168.0.106:/rhome/nisuser-nfs-1 40G 9.9G 28G 27% /rhome/nisuser-nfs-1
192.168.0.106:/rhome/nisuser-nfs-2 40G 9.9G 28G 27% /rhome/nisuser-nfs-2
[nisuser-nfs2@nis-client1 桌面]$
注释：发现一个问题，当nisuser-nfs1注销后用nisuser-nfs2登录时发现nisuser-nfs1的目录还在，解决办法可以是更改/etc/sysconfig/autofs中的TIMEOUT=，默认是300，可以设置的尽可能小，使得nisuser-nfs1注销的同时其目录页断开连接，另一个办法就是设置权限，在服务器/etc/export中指定目录的所属用户即可；
28、更改nisuser-nfs1和nisuser-nfs2用户的密码：
[root@nis-server1 桌面]# echo root123 |passwd --stdin nisuser-nfs1
更改用户 nisuser-nfs1 的密码 。
passwd： 所有的身份验证令牌已经成功更新。
[root@nis-server1 桌面]# echo root123 |passwd --stdin nisuser-nfs2
更改用户 nisuser-nfs2 的密码 。
passwd： 所有的身份验证令牌已经成功更新。
[root@nis-server1 桌面]# /usr/lib64/yp/ypinit -m
At this point, we have to construct a list of the hosts which will run NIS
servers. nis-server1 is in the list of NIS server hosts. Please continue to add
the names for the other hosts, one per line. When you are done with the
list, type a <control D>.
next host to add: nis-server1
next host to add:
The current list of NIS servers looks like this:
nis-server1
Is this correct? [y/n: y]
We need a few minutes to build the databases...
Building /var/yp/ocean-peak/ypservers...
Running /var/yp/Makefile...
gmake[1]: Entering directory `/var/yp/ocean-peak‘

nis-server1 has been set up as a NIS master server.
Now you can run ypinit -s nis-server1 on all slave server.
[root@nis-server1 桌面]#
29、client更改/etc/sysconfig/autofs中TIMEOUT设置成TIMEOUT=3；
30、使用nisuser-nfs1登录：
[nisuser-nfs1@nis-client1 桌面]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 40G 9.9G 28G 27% /
tmpfs 932M 244K 932M 1% /dev/shm
/dev/sda1 52G 180M 49G 1% /data
192.168.0.106:/rhome/nisuser-nfs-1 40G 9.9G 28G 27% /rhome/nisuser-nfs-1
[nisuser-nfs1@nis-client1 桌面]$
31、使用nisuser-nfs2登录：
[nisuser-nfs2@nis-client1 桌面]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 40G 9.9G 28G 27% /
tmpfs 932M 244K 932M 1% /dev/shm
/dev/sda1 52G 180M 49G 1% /data
192.168.0.106:/rhome/nisuser-nfs-2 40G 9.9G 28G 27% /rhome/nisuser-nfs-2
[nisuser-nfs2@nis-client1 桌面]$
由此发现更改了TIMEOUT后下一个用户登录后看不到上一个用户的目录；
32、试用nisuser-nfs2的用户cd nisuser-nfs1的目录：
[nisuser-nfs2@nis-client1 桌面]$ cd /rhome/
[nisuser-nfs2@nis-client1 rhome]$ ls
nisuser-nfs-2
[nisuser-nfs2@nis-client1 rhome]$ cd nisuser-nfs-1
bash: cd: nisuser-nfs-1: 权限不够
[nisuser-nfs2@nis-client1 rhome]$
目的达到。
