1.环境准备

以用户名[root@doudou ~] ip：192.168.24.181/24为服务端

以用户名[root@linfan ~] ip：192.168.24.132/24为客户端

服务端配置

2.基础环境配置

关闭firewalld防火墙

[root@doudou ~]# systemctl disable firewalld

[root@doudou ~]# systemctl stop firewalld

关闭selinux

[root@doudou ~]# sed -ri '#^SELINUX=#cSELINUX=Disabled' /etc/selinux/config

[root@doudou ~]# setenforce 0

安装NFS-Server

//安装nfs服务主程序

[root@doudou ~]# yum -y install nfs-utils rpcbind

3.启动NFS-server

//启动rpcbind服务，并查看rpc注册信息

[root@doudou ~]# systemctl start rpcbind

[root@doudou ~]# systemctl enable rpcbind

[root@doudou ~]# systemctl start nfs-server

[root@doudou ~]# systemctl enable nfs-server

[root@doudou ~]# rpcinfo -p localhost

program vers proto port service

100000 4 tcp 111 portmapper

100000 3 tcp 111 portmapper

100000 2 tcp 111 portmapper

100000 4 udp 111 portmapper

100000 3 udp 111 portmapper

100000 2 udp 111 portmapper

4.查看系统中运行的NFS相关进程

[root@doudou ~]# ps -ef | egrep "rpc|nfs"

5.NFS服务端配置共享目录

编辑nfs主配置文件，共享目录linfan至192.168.24.132/24,可读写，统一用户

[root@doudou ~]# vi /etc/exports

/data 192.168.24.132/24(rw,sync,all_squash)

创建需要共享的目录

[root@doudou ~]# mkdir /data

重启NFS-server服务，查看共享文件是否存在

[root@doudou ~]# systemctl restart nfs-server

[root@doudou ~]# cat /var/lib/nfs/etab

/data 192.168.24.132/24(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,all_squash,no_subtree_check,secure_locks,acl,no_pnfs,anonuid=65534,anongid=65534,sec=sys,secure,root_squash,all_squash)

nfs统一给客户端为65534用户权限,查看65534属于哪个用户，递归赋予data目录nfsnobody

[root@doudou ~]# grep "65534" /etc/passwd

nfsnobody:x:65534:65534:Anonymous NFS User:/var/lib/nfs:/sbin/nologin

[root@doudou ~]# chown -R nfsnobody.nfsnobody /data/

[root@doudou ~]# ls /data/ -dl

drwxr-xr-x. 2 nfsnobody nfsnobody 6 Aug 2 16:12 /data/

重启nfs-server服务生效

[root@doudou ~]# systemctl restart nfs-server

客户端

1.关闭防火墙,关闭selinux

[root@linfan ~]# systemctl stop firewalld

[root@linfan ~]# systemctl disable firewalld

[root@doudou ~]# sed -ri '#^SELINUX=#cSSELINUX=Disabled' /etc/selinux/config

[root@doudou ~]# setenforce 0

2.安装相关服务，仅启动rpcbind服务即可

[root@linfan ~]# yum -y install nfs-utils rpcbind

[root@linfan ~]# systemctl enable rpcbind

[root@linfan ~]# systemctl start rpcbind

3.客户端查看远程服务器提供可挂载信息

[root@linfan ~]# showmount -e 192.168.24.181

Export list for 192.168.24.181:

/data 192.168.24.132/24

4.客户端挂载共享data

[root@linfan ~]# mount -t nfs 192.168.24.181:/data /mnt

[root@linfan ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/centos-root 17G 6.0G 12G 35% /

devtmpfs 478M 0 478M 0% /dev

tmpfs 489M 0 489M 0% /dev/shm

tmpfs 489M 26M 464M 6% /run

tmpfs 489M 0 489M 0% /sys/fs/cgroup

/dev/sda1 1014M 125M 890M 13% /boot

tmpfs 98M 0 98M 0% /run/user/0

192.168.24.181:/data 17G 1.8G 16G 11% /mnt

5.测试nfs是否成功

客户端操作

在客户端mnt下创建一个文件hello

## [root@linfan ~]# ls /mnt/

[root@linfan ~]# cd /mnt/

[root@linfan mnt]# touch hello

[root@linfan mnt]# ls

hello

服务端操作

在服务端查看data下是否存在文件hello

[root@doudou ~]# ls /data

hello
