Linux Services NFS Configuration detailed steps

1. Environmental preparedness

以用户名[[email protected] ~] ip：192.168.24.181/24为服务端以用户名[[email protected] ~] ip：192.168.24.132/24为客户端

Server-side configuration 2. Basic Environment configuration Shutdown FIREWALLD Firewall

[[email protected] ~]# systemctl disable firewalld[[email protected] ~]# systemctl stop firewalld

Turn off SELinux

[[email protected] ~]# sed -ri ‘#^SELINUX=#cDELINUX=Disabled‘ /etc/selinux/config[[email protected] ~]# setenforce 0

Install nfs-server//to install the NFS service main program

[[email protected] ~]# yum -y install nfs-utils rpcbind

3. Start nfs-server//start the Rpcbind service and view the RPC registration information

[[email protected] ~]# systemctl start rpcbind[[email protected] ~]# systemctl enable rpcbind[[email protected] ~]# systemctl start nfs-server[[email protected] ~]# systemctl enable nfs-server[[email protected] ~]# 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. View the NFS-related processes running in the system

[[email protected] ~]# ps -ef | egrep "rpc|nfs"

5.NFS server-side configuration shared directory

Edit NFS Master profile, shared directory Linfan to 192.168.24.132/24, read/write, unified user

[[email protected] ~]# vi /etc/exports/data 192.168.24.132/24(rw,sync,all_squash)

Create a directory that needs to be shared

[[email protected] ~]# mkdir /data

Restart the Nfs-server service to see if the shared file exists

[[email protected] ~]# systemctl restart nfs-server[[email protected] ~]# 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 Unified to the client for 65534 user rights, see 65534 belongs to which user, recursively give the data directory Nfsnobody

[[email protected] ~]# grep "65534" /etc/passwdnfsnobody:x:65534:65534:Anonymous NFS User:/var/lib/nfs:/sbin/nologin[[email protected] ~]# chown -R nfsnobody.nfsnobody /data/[[email protected] ~]# ls /data/ -dldrwxr-xr-x. 2 nfsnobody nfsnobody 6 Aug  2 16:12 /data/

Restart Nfs-server service in effect

[[email protected] ~]# systemctl restart nfs-server

Client 1. Turn off the firewall and turn off SELinux

[[email protected] ~]# systemctl stop firewalld[[email protected] ~]# systemctl disable firewalld[[email protected] ~]# sed -ri ‘#^SELINUX=#cDELINUX=Disabled‘ /etc/selinux/config[[email protected] ~]# setenforce 0

2. Install related services, only start Rpcbind service

[[email protected] ~]# yum -y install nfs-utils rpcbind[[email protected] ~]# systemctl enable rpcbind[[email protected] ~]# systemctl start rpcbind

3. Client view remote server to provide mount information

[[email protected] ~]# showmount -e 192.168.24.181Export list for 192.168.24.181:/data 192.168.24.132/24

4. The client mounts the shared data

[[email protected] ~]# mount -t nfs 192.168.24.181:/data /mnt[[email protected] ~]# df -hFilesystem               Size  Used Avail Use% Mounted on/dev/mapper/centos-root   17G  6.0G   12G  35% /devtmpfs                 478M     0  478M   0% /devtmpfs                    489M     0  489M   0% /dev/shmtmpfs                    489M   26M  464M   6% /runtmpfs                    489M     0  489M   0% /sys/fs/cgroup/dev/sda1               1014M  125M  890M  13% /boottmpfs                     98M     0   98M   0% /run/user/0192.168.24.181:/data      17G  1.8G   16G  11% /mnt

5. Test whether NFS succeeded client operation create a file under client mnt hello

## [[email protected] ~]# ls /mnt/[[email protected] ~]# cd /mnt/[[email protected] mnt]# touch hello[[email protected] mnt]# lshello

Server-side operation to see if there is a file hello under Data on the server

[[email protected] ~]# ls /datahello
