nfs服务器

1.开放/nfs/shared目录，供所有用户查阅资料

• 在服务端和客户端安装nfs-utils

[root@sever ~]# yum -y install nfs-utils
Loaded plugins: product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

• 启动

[root@sever ~]# systemctl restart rpcbind nfs-server

[root@client ~]# systemctl restart rpcbind nfs-server

• 在服务器上创建/nfs/shared目录(供所有用户查阅资料)

[root@sever ~]# mkdir -p /nfs/shared

• 修改/etc/exports文件

[root@sever ~]# cat /etc/exports
/nfs/shared *(ro)

• 重启

[root@server ~]# exportfs -r

• 在客户端查看服务器的共享目录

[root@client ~]# showmount -e 192.168.147.28
Export list for 192.168.147.28:
/nfs/shared *

• 客户端将nfs共享的目录挂载到指定目录下

[root@client ~]# mount -t nfs 192.168.147.28:/nfs/shared /client
[root@client ~]# df -Th

• 在服务器上创建文件或目录

[root@server ~]# cd /nfs/shared/
[root@server shared]# ls
[root@server shared]# mkdir aaa

---

2.开放/nfs/upload目录为x.x.x.0/24网段的数据上传目录，并将所有用户及所属的用户组都映射为nfs-upload，其UID与GID均为3000

• 在服务端创建/nfs/upload目录，创建用户和组为nfs-upload，指定UID,GID为3000

[root@server ~]# mkdir /nfs/upload
[root@sever ~]# useradd -r -u 300 nfs-upload
[root@server ~]# id nfs-upload
uid=300(nfs-upload) gid=300(nfs-upload) groups=300(nfs-upload)
[root@server ~]# 

• 修改/nfs/exports文件

[root@server ~]# vim /etc/exports
[root@server ~]# cat /etc/exports
/nfs/shared *(ro)
/nfs/upload 192.168.120.0/24(rw,anonuid=3000,anongid=3000)
[root@server ~]# exportfs -r

• 在客户端查看nfs共享的目录

[root@client ~]# showmount -e 192.168.147.28
Export list for 192.168.147.28:
/nfs/shared *
/nfs/upload 192.168.147.0/24

• 将共享目录属组改为nfs-upload

[root@server ~]# chown -R 3000 /nfs/upload/
[root@server ~]# chgrp -R 3000 /nfs/upload/
[root@server ~]# ll /nfs/

3.配置ssh免密登陆，能够通过客户端主机通过redhat用户和服务端主机基于公钥验证方式进行远程连接server端创建用户redhat,切换用户为redhat,并制作公钥。

• 在服务器端创建用户，制作公钥

• 创建密钥

• 测试是否可以进行免密登录
