CentOS7 nfs搭建

网络环境

192.168.2.164 nfs服务器
192.168.2.165 nfs客户端

安装环境

yum install nfs-utils.x86_64 rpcbind -y

查看gid与uid

[root@localhost /]# id root
uid=0(root) gid=0(root) groups=0(root)

修改配置文件（默认是空文本）

[root@localhost ~]# cat /etc/exports
/opt/test       192.168.2.165(rw,no_root_squash,no_all_squash,sync,anonuid=0,anongid=0)

ll_squash：将远程访问的所有普通用户及所属组都映射为匿名用户或用户组（nfsnobody）；
no_all_squash：与all_squash取反（默认设置）；
root_squash：将root用户及所属组都映射为匿名用户或用户组（默认设置）；
no_root_squash：与rootsquash取反；
anonuid=xxx：将远程访问的所有用户都映射为匿名用户，并指定该用户为本地用户（UID=xxx）；
anongid=xxx：将远程访问的所有用户组都映射为匿名用户组账户，并指定该匿名用户组账户为本地用户组账户（GID=xxx）；

创建目录及开启服务器

[root@localhost /]# mkdir /opt/test
[root@localhost /]# systemctl stop firewalld.service
[root@localhost /]# systemctl start rpcbind.service
[root@localhost /]# systemctl start nfs-server.service   
[root@localhost /]# systemctl enable firewalld.service
[root@localhost /]# systemctl enable rpcbind.service
[root@localhost /]# systemctl enable nfs-server.service   

查看可使用nfs mount情况

[root@localhost /]# showmount -e
Export list for localhost.localdomain:
/opt/test 192.168.2.165

前提可识别主机名，使用hostname查看主机名然后添加到/etc/hosts中即可
[root@localhost /]# hostname
[root@localhost /]# vim /etc/hosts

客户端

yum install nfs-utils.x86_64 rpcbind -y

创建目录及开启服务器

[root@localhost /]# mkdir /opt/test
[root@localhost /]# systemctl stop firewalld.service
[root@localhost /]# systemctl start rpcbind.service
[root@localhost /]# systemctl start nfs-server.service   
[root@localhost /]# systemctl enable firewalld.service
[root@localhost /]# systemctl enable rpcbind.service
[root@localhost /]# systemctl enable nfs-server.service   

挂载

[root@localhost test]# mount 192.168.2.164:/opt/test /opt/test

开机自动挂载

[root@localhost test]# vim /etc/fstab 
    # /etc/fstab

    192.168.2.164:/opt/test /opt/test           nfs4    defaults        0 0

查看nfs版本-在客户端

[root@localhost test]# nfsstat -m
/opt/test from 192.168.2.164:/opt/test
