篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了企业级NFS网络文件共享服务相关的知识，希望对你有一定的参考价值。
虚拟实验：
操作系统：CentOS release 6.8 (Final)
虚拟机：VMware
任务：NFS网络文件共享服务
默认是没有安装NFS软件包，NFS主要功能是通过网络让不同的主机系统之间可以共享文件或目录。NFS网络文件系统很像Windows系统的网络共享、安全功能、网络驱动映射，而互联网中小型网站集群架构后端常用NFS进行数据共享。
NFS服务器IP: 192.168.222.130
NFS客户端IP1: 192.168.222.138
NFS客户端IP2：192.168.222.139
N个客户端
NFS服务器端设置：
[[email protected] ~]# yum install nfs-utils rpcbind –y
[[email protected] ~]# rpm -qa nfs-utils rpcbind
nfs-utils-1.2.3-70.el6_8.2.x86_64
rpcbind-0.2.0-12.el6.x86_64
[[email protected] ~]# /etc/init.d/rpcbind status

NFS服务的相关操作：
[[email protected] ~]# /etc/init.d/nfs status
rpc.svcgssd 已停
rpc.mountd is stopped
nfsd is stopped
[[email protected] ~]# /etc/init.d/nfs start
Starting NFS services: [ OK ]
Starting NFS mountd: [ OK ]
Starting NFS daemon: [ OK ]
正在启动 RPC idmapd： [确定]

配置NFS服务器端开机自动启动： chkconfig和/etc/rc.local的配置二选一即可。
[[email protected] ~]# chkconfig rpcbind on
[[email protected] ~]# chkconfig nfs on
[[email protected] ~]# chkconfig --list rpcbind
rpcbind 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[[email protected] ~]# chkconfig --list nfs
nfs 0:off 1:off 2:on 3:on 4:on 5:on 6:off
配置NFS服务器端：配置文件路径
创建需要共享的目录并授权：
-bash: l: command not found
[[email protected] ~]# mkdir /data
[[email protected] ~]# ll /data
total 0
[[email protected] ~]# chown -R nfsnobody.nfsnobody /data
[[email protected] ~]# ls -ld /data
drwxr-xr-x. 2 nfsnobody nfsnobody 4096 Dec 28 23:54 /data
配置NFS服务配置文件：
[[email protected] ~]# vi /etc/exports
/data 192.168.222.0/24(rw,sync)
[[email protected] ~]# exportfs –rv #查看挂载信息
exporting 192.168.222.0/24:/data
[[email protected] ~]# showmount -e localhost #查看本地服务器挂载情况
Export list for localhost:
/data 192.168.222.0/24
[[email protected] /]# mount -t nfs 192.168.222.130:/data /mnt
[[email protected] /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 27G 3.0G 23G 12% /
tmpfs 495M 0 495M 0% /dev/shm
/dev/sda1 93M 51M 38M 58% /boot
192.168.222.130:/data 27G 3.0G 23G 12% /mnt
NFS Client端执行的操作：
安装客户端软件rpcbind
[[email protected] ~]# yum install rpcbind –y
[[email protected] ~]# rpm -qa rpcbind
rpcbind-0.2.0-12.el6.x86_64
[[email protected] ~]# showmount
-bash: showmount: command not found
[[email protected] ~]# yum install nfs-utils –y
启动RPC服务
[[email protected] ~]# /etc/init.d/rpcbind start
正在启动 rpcbind： [确定]
[[email protected] ~]# showmount -e 192.168.222.130
Export list for 192.168.222.130:
/data 192.168.222.0/24
[[email protected] ~]# mount -t nfs 192.168.222.130:/data /mnt
[[email protected] ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 27G 939M 25G 4% /
tmpfs 495M 0 495M 0% /dev/shm
/dev/sda1 93M 51M 38M 58% /boot
192.168.222.130:/data 27G 3.0G 23G 12% /mnt
[[email protected] ~]# mount
/dev/sda3 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
192.168.222.130:/data on /mnt type nfs (rw,vers=4,addr=192.168.222.130,clientaddr=192.168.222.138)
[[email protected] ~]# ls /mnt/
[[email protected] ~]# mkdir /mnt/source
[[email protected] ~]# ls -l /mnt
总用量 4
drwxr-xr-x. 2 nfsnobody nfsnobody 4096 12月 29 2016 source
将rpcbind服务和挂载加入开机自启动，如下：
[[email protected] ~]# echo "/etc/inti.d/rpcbind start" >>/etc/rc.local
[[email protected] ~]# echo "/bin/mount -t nfs 192.168.222.130:/data /mnt" >>/etc/rc.local
[[email protected] ~]# tail -2 /etc/rc.local
/etc/inti.d/rpcbind start
/bin/mount -t nfs 192.168.222.130:/data /mnt
注意：关于防火墙和文件权限的相关设置在这里省略。
