NFS网络文件服务器:
windows上面叫文件共享。
多台linux服务器,只要有一台搭建了NFS服务器并把文件共享出来,其余几台服务器就可以来访问。

root@ubuntu:/etc# ll | grep exports
-rw-r--r-- 1 root root 389 10月 10 2012 exports
root@ubuntu:/etc# vim exports
/home/nfs *(sync,ro)
写完之后要重启nfs和portmap才能够生效。
root@ubuntu:/etc# service portmap restart
root@ubuntu:/etc# service nfs-utils restart
我们要共享的目录是/home/nfs,现在nfs所属的账号是root,要改成nfs,
root@ubuntu:/home# mkdir nfs
root@ubuntu:/home# ll
drwxr-xr-x 2 root root 4096 2月 25 07:39 nfs/
nfs账号是存在的,root@ubuntu:/home# vim /etc/passwd
nfsnobody:x:125:65534::/var/lib/nfs:/bin/false
root@ubuntu:/home# chown -R nfsnobody:nfsnobody nfs/ (修改文件的宿主)
NFS服务端需要启动2个进程,并修改配置文件,修改文件宿主。
客户端:
创建一个目录/mnt/share
chown -R nfsnobody:nfsnobody share/
mount -t nfs 192.168.229.134:/home/nfs /mnt/share(把另一台服务器共享的文件192.168.229.134:/home/nfs映射到本地来/mnt/share)
