检查自己的rpcbind服务是不是比nfs服务后启动
第一步：重启一下rpcbind服务和nfs服务
[root@nfs01 ~]# /etc/init.d/rpcbind start&& /etc/init.d/rpcbind rtstart
[root@nfs01 ~]# /etc/init.d/nfs start &&/etc/init.d/nfs rtstart
第二步：showmount 看下服务端是否有共享目录
[root@nfs01 ~]# showmount -e 172.16.1.31
Export list for 172.16.1.31:
/data 172.16.1.0/24
第三步：telnet 看是否连的上服务端
[root@nfs01 ~]# telnet 172.16.1.31 22
Trying 172.16.1.31...
Connected to 172.16.1.31.
Escape character is ‘^]‘.
SSH-2.0-OpenSSH_5.3
第四步：ping 服务端IP
[root@nfs01 ~]# ping 172.16.1.31 -c2
PING 172.16.1.31 (172.16.1.31) 56(84) bytes ofdata.

--- 172.16.1.31 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss,time 1012ms
rtt min/avg/max/mdev = 0.062/0.062/0.063/0.007 ms
第五步：检查防火墙是否关闭
[root@nfs01 ~]# /etc/init.d/iptables stop&& /etc/init.d/iptables status
第六步：配置文件/etc/exports是否语法错误
[root@nfs01 ~]# cat /etc/exports
#data gongxiang by xiaofang at 20160425
/data 172.16.1.0/24(rw,sync,all_squash)
第七步：检查是否在设置开机自启动
①[root@nfs01 ~]# cat /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all theother init scripts.
# You can put your own initialization stuff in hereif you don‘t
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
/etc/init.d/rpcbind start
/etc/init.d/nfs start
②[root@nfs01 ~]# chkconfig --list|egrep"rpcbind|nfs\b"
nfs 0:off 1:off 2:on 3:on 4:on 5:on 6:off
nfs-rdma 0:off 1:off 2:off 3:off 4:off 5:off 6:off
rpcbind 0:off 1:off 2:on 3:on 4:on 5:on 6:off
第一步：重启一下rpcbind服务
[root@nfs01 ~]# /etc/init.d/rpcbind start&& /etc/init.d/rpcbind rtstart
第二步：showmount 看下服务端是否有共享目录
[root@nfs01 ~]# showmount -e 172.16.1.31
Export list for 172.16.1.31:
/data 172.16.1.0/24
第三步：telnet 看是否连的上服务端
[root@nfs01~]# telnet 172.16.1.31 22
Trying172.16.1.31...
Connectedto 172.16.1.31.

第四步：ping 服务端IP
[root@nfs01~]# ping 172.16.1.31 -c2

rttmin/avg/max/mdev = 0.062/0.062/0.063/0.007 ms
第五步：检查防火墙是否关闭
[root@nfs01~]# /etc/init.d/iptables stop && /etc/init.d/iptables status
第六步：检查是否挂载上
[root@backup ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 9.1G 1.5G 7.2G 18% /
tmpfs 112M 0 112M 0% /dev/shm
/dev/sda1 190M 36M 145M 20% /boot
172.16.1.31:/data 9.1G 1.5G 7.2G 17% /mnt
第七步：是否开机自动挂载
①[root@backup~]# cat /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all theother init scripts.
# You can put your own initialization stuff in hereif you don‘t
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
>/etc/udev/rules.d/70-persistent-net.rules
/usr/bin/rsync --daemon
/etc/init.d/rpcbind start
/bin/mount -t nfs 172.16.1.31:/data /mnt
②[root@nfs01~]# chkconfig --list|grep netfs
netfs 0:off 1:off 2:off 3:on 4:off 5:off 6:off
[root@nfs01 ~]# cat /etc/fstab

注释：
[U1]nfs启动后会发现NFS服务向rcp服务注入的端口信息，NFS服务启动后我们会发现多了很多端口和功能的对应
[U2]111端口是nfs服务对外提供服务的主端口
[U3]#<==检查文件一致性
[U4]#<==磁盘配额进程（remote quta server）
[U5]#<==权限管理验证等（NFS mount daemon）
[U6]NFS主进程，管理登入，ID身份判别等
[U7]设置nfs共享目录及目录的权限属性。
注意该目录一定要存在。sync是写入磁盘。all_spuash是把访问该目录的用户压缩成匿名用户，即下面的nfsnobody用户。
[U8]修改该目录的属主和属组
nfsnobody用户是在安装nfs后自动生成的（Cos6有）。
[U9]客户端安好后把NFS服务和rpcbind服务设置成开机自启动
[U10]可以放在/etc/rc.local里
[root@nfs01 backup]# cat /etc/rc.local
#!/bin/sh
#
# This script will be executed *after*all the other init scripts.
# You can put your own initializationstuff in here if you don‘t
# want to do the full Sys V style initstuff.
touch /var/lock/subsys/local
/etc/init.d/rpcbindstart
/etc/init.d/nfsstart
[U11]挂载点一定要存在
