nfs为网络文件系统也可理解为文件共享，方式为服务器上安装nfs服务，客户端通过挂在的方式把服务器上的目录挂载到本地，实现文件共享
1.查看有没有安装nfs
rpm -qa |grep nfs
2.安装nfs
yum -y install nfs-utils
3.开启服务
/etc/init.d/nfs start
/etc/init.d/rpcbind start
4.配置exports
vi/etc/exports
/home/zuzhao 192.168.1.0 255.255.254.0（rw）
5.关闭防火墙
service iptbales stop
7.重启nfs
service nfs restart
8.服务器目录改写权限
chmod 777 /home/zuzhao
9.客户端进行挂载
mount -t nfs 192.168.1.52:/home/zuzhao//tmp/zuzhao/
报错
mount.nfs: access denied by server whilemounting 192.168.1.52:/home/zuzhao/ You have new mail in /var/spool/mail/root
查看报错日志
cat /var/log/messages |grep mount
报错日志截图如下
Dec 21 14:29:04 CactiEZ rpc.mountd[1770]:Failed to register (mountd, 3, tcp6): svc_reg() err: RPC: Remote system error -Connection refused
提示为端口太大的原因服务器查看端口如下
netstat -apn | grep mount
[[email protected] zuzhao]# netstat -apn | grepmount

udp 0 0 :::41836 :::* 26820/rpc.mountd
udp 0 0 :::59969 :::* 26820/rpc.mountd
解决方法如下：
修改配置文件
vi /etc/exports
/home/zuzhao *(insecure,rw,async,no_root_squash)
添加如上
重启nfs服务
重新挂载
[[email protected] tmp]# mount -t nfs192.168.1.52:/home/zuzhao/ /tmp/zuzhao/
You have new mail in /var/spool/mail/root
[[email protected] tmp]# ls
cactiez ins.log ks-script-KlcQlI ks-script-KlcQlI.log yum.log zuzhao
[[email protected] zuzhao]# ls
1.txt
[[email protected] zuzhao]#
完成！
