NFS安装配置

安装相关的包

#首先检查本机是否安装了rpcbind.x86_64、nfs-utils.x86_64安装包
[root@localhost ~]# yum list installed | grep rpcbind
rpcbind.x86_64                         0.2.0-38.el7                    @anaconda
[root@localhost ~]# yum list installed | grep nfs-utils
nfs-utils.x86_64                       1:1.3.0-0.33.el7                @anaconda

#经检验主机已经安装了nfs的包，否则执行下面的安装指令
yum install -y nfs-utils rpcbind

关闭防火墙

systemctl stop firewalld;
iptables -F ;
setenforce 0;

创建共享路径

mkdir /home/nfs_share

编辑/etc/exports

# 对所有用户开放
/home/nfs_share *(rw,no_root_squash,insecure)

#对指定ip开放
/tmp         192.168.100.0/24(ro)   localhost(rw)   *.ev.ncku.edu.tw(ro,sync)
[分享目录]   [第一部主機(權限)]     [可用主机名]    [可用萬用字元]

/home/david 192.168.1.0/24(rw)

为rpcbind和nfs做开机启动，然后分别启动rpcbind和nfs服务，注意启动顺序

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

验证rpc是否给nfs提供服务

检查含有nfs的服务则证明ok

[root@localhost nfs_share]# rpcinfo -p 
   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
    100005    1   udp  20048  mountd
    100005    1   tcp  20048  mountd
    100024    1   udp  57846  status
    100005    2   udp  20048  mountd
    100024    1   tcp  55283  status
    100005    2   tcp  20048  mountd
    100005    3   udp  20048  mountd
    100005    3   tcp  20048  mountd
    100003    3   tcp   2049  nfs
    100003    4   tcp   2049  nfs
    100227    3   tcp   2049  nfs_acl
    100003    3   udp   2049  nfs
    100003    4   udp   2049  nfs
    100227    3   udp   2049  nfs_acl
    100021    1   udp  33783  nlockmgr
    100021    3   udp  33783  nlockmgr
    100021    4   udp  33783  nlockmgr
    100021    1   tcp  42768  nlockmgr
    100021    3   tcp  42768  nlockmgr
    100021    4   tcp  42768  nlockmgr

查看可挂载的目录和ip

[root@localhost nfs_share]# showmount -e
Export list for localhost.localdomain:
/home/nfs_share *

使用别的主机验证

[root@edunode3 ~]# showmount -e 10.6.6.192
Export list for 10.6.6.192:
/home/nfs_share *
