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

[root@localhost zuzhao]# netstat -apn | grepmount

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

[root@CactiEZ tmp]# mount -t nfs192.168.1.52:/home/zuzhao/ /tmp/zuzhao/

You have new mail in /var/spool/mail/root

[root@CactiEZ tmp]# ls

cactiez ins.log  ks-script-KlcQlI  ks-script-KlcQlI.log  yum.log zuzhao

[root@CactiEZ zuzhao]# ls

1.txt

[root@CactiEZ zuzhao]#

完成！
