RECE-nfs共享文件

实验要求
架设一台NFS服务器，并按照以下要求配置

1、开放/nfs/shared目录，供所有用户查询资料

2、开放/nfs/upload目录，为192.168.xxx.0/24网段主机可以上传目录，

并将所有用户及所属的组映射为nfs-upload,其UID和GID均为210

3、将/home/tom目录仅共享给192.168.xxx.xxx这台主机，并只有用户tom可以完全访问该目录

下载工具

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

关闭防火墙并开启服务

[root@localhost zzy]# systemctl stop firewalld
[root@localhost zzy]# setenforce 0
[root@localhost zzy]# systemctl start nfs-server

服务机配置

[root@localhost zzy]# vim /etc/exports
[root@localhost zzy]# cat /etc/exports
/nfs/shared  *(ro,sync)
/nfs/upload 192.168.64.0/24(rw,anonuid=210,anongid=210,sync)
/home/tom   192.168.64.132(rw)[root@localhost zzy]# mkdir /nfs/shared -pv
mkdir: created directory '/nfs'
mkdir: created directory '/nfs/shared'
[root@localhost zzy]# touch /nfs/shared/{0..10}
[root@localhost zzy]# mkdir /nfs/upload
[root@localhost zzy]# chmod o+w /nfs/upload
[root@localhost zzy]# useradd -u 210 -r nfs-upload
[root@localhost zzy]# useradd tom
[root@localhost zzy]# id tom

[root@localhost zzy]# ll /home/tom/ -d
