NFS服务器题目
1、开放/nfs/shared目录，供所有用户查询资料；
2、开放/nfs/upload目录，供所有用户上传下载资料；
步骤
1、开放/nfs/shared目录，供所有用户查询资料；
# 下载服务
[root@localhost ~]# yum install rpcbind
[root@localhost ~]# yum install nfs-utils
# 建立目录
[root@localhost /]# mkdir -pv /nfs/shared
mkdir: created directory '/nfs'
mkdir: created directory '/nfs/shared'
# 编辑配置文件
[root@localhost /]# vim /etc/exports
/nfs/shared *(ro)
# 重启服务,关闭防火墙
[root@localhost /]# systemctl stop firewalld
[root@localhost /]# setenforce 0
[root@localhost /]# systemctl restart nfs-server
客户器
# 创建目录
[root@localhost /]# mkdir /client
# 查看文件
[root@localhost /]# showmount -e 192.168.182.132
Export list for 192.168.182.132:
/nfs/shared *
# 加载文件
[root@localhost /]# mount 192.168.182.132:/nfs/shared /client
[root@localhost client]# df -h
df: /work: Stale file handle

1.测试
[root@localhost shared]# touch file
[root@localhost client]# ll
total 0
-rw-r--r--. 1 root root 0 Nov 15 04:32 file
2、开放/nfs/upload目录，供所有用户上传下载资料；
服务端
# 创建目录
[root@localhost nfs]# mkdir upload
# 编辑配置文件
[root@localhost nfs]# vim /etc/exports
/nfs/shared *(ro)
/nfs/upload *(rw)
# 重新加载文件
[root@localhost nfs]# exportfs -r
# 查看
[root@localhost nfs]# showmount -e 192.168.182.132
Export list for 192.168.182.132:
/nfs/upload *
/nfs/shared *
# 加权限
[root@localhost nfs]# chmod o+w upload/
客户端
# 创建目录
[root@localhost /]# mkdir /client1
# 加载文件
[root@localhost /]# mount 192.168.182.132:/nfs/upload /client1
# 查看
[root@localhost /]# df -h
