NFS共享文件系统搭建

分享个人觉得写的不错的NFS相关介绍 点击跳转即可

• server端
  安装

yum install -y nfs-utils

修改配置文件

vim /etc/exports
/home/share/ 192.168.1.0/24(rw,sync,fsid=0)
#/home/share/ 192.168.1.1(rw,sync,fsid=0) 192.168.1.2(rw,sync,fsid=0)

测试

exportfs -v
exportfs: /etc/exports:1: syntax error: bad option list

出现上述错误，一般为格式不正确，中英文、空格等 请自行校对

正确显示

exportfs -v
/home/share
		192.168.1.0/24(rw,sync,fsid=0)(sync,wdelay,hide,no_subtree_check,fsid=0,sec=sys,rw,secure,root_squash,no_all_squash)
		

启动服务

systemctl enable rpcbind.service
systemctl enable nfs-server.service

systemctl start rpcbind.service 
systemctl start nfs-server.service

查看rpc服务

rpcinfo -p

开启对应的防火墙端口

[root@test home]# firewall-cmd  --zone=public --add-port=111/tcp 
success
[root@test home]# firewall-cmd  --zone=public --add-port=2049/tcp 
success
[root@test home]# firewall-cmd  --zone=public --add-port=2049/udp
success
[root@test home]# firewall-cmd  --zone=public --add-port=111/udp 
success
[root@test home]# firewall-cmd  --zone=public --add-port=20048/udp 
success
[root@test home]# firewall-cmd  --zone=public --add-port=20048/tcp 
success
[root@test home]# firewall-cmd  --zone=public --add-port=35248/tcp 
success
[root@test home]# firewall-cmd  --zone=public --add-port=38535/udp
success

重启服务

systemctl restart rpcbind.service 
systemctl restart nfs-server.service

• 客户端client
  client只需安装nfs模块无需启动nfs

yum install nfs-utils

启动rpc服务

 systemctl enable rpcbind.service
Created symlink from /etc/systemd/system/multi-user.target.wants/rpcbind.service to /usr/lib/systemd/system/rpcbind.service.
systemctl start rpcbind.service 

测试：

showmount -e 192.168.1.10
clnt_create: RPC: Port mapper failure - Unable to receive: errno 113 (No route to host)

出现此错误 一般是端口未成功开放，到nfs服务端开启端口

成功测试

[root@test home] ~]$ showmount -e 192.168.1.10
Export list for 192.168.1.10:
/home/share 192.168.1.0/24
