一. 配置YUM软件仓库到CD-ROM(略)
二. 配置NIS服务器端

  1. 安装服务 
    [root@  localhost ~]# yum -y install ypserv rpcbind
[root@  localhost ~]# ypdomainname nis.test 
[root@  localhost ~]# echo "NISDOMAIN=nis.test" >> /etc/sysconfig/network 
[root@  localhost ~]# vim /var/yp/securenets
255.0.0.0       127.0.0.0
255.255.255.0   192.168.100.0
[root@  localhost ~]# vi /etc/hosts
192.168.100.71 sev01.nis.test srv01
192.168.100.72 sev02.nis.test srv02
[root@  localhost ~]# systemctl start rpcbind ypserv ypxfrd yppasswdd 
[root@  localhost ~]# systemctl enable rpcbind ypserv ypxfrd yppasswdd
[root@  localhost ~]# /usr/lib64/yp/ypinit -m
next host to add:   sev01.nis.test
next host to add:# Ctrl + D 
The current list of NIS servers looks like this:
sev01.nis.test
Is this correct? [y/n: y] y# y
  2. 增加用户之后要在NIS数据库同步 
    [root@localhost ~]# cd /var/yp 
[root@localhost yp]# make
  3. 配置防火墙规则 
    [root@localhost ~]# vim /etc/sysconfig/network
# 附加在最后
YPSERV_ARGS="-p 944"
YPXFRD_ARGS="-p 945"
[root@localhost ~]# vim /etc/sysconfig/yppasswdd
# 修改成
YPPASSWDD_ARGS="--port 946"
[root@localhost ~]# systemctl restart rpcbind ypserv ypxfrd yppasswdd
[root@localhost ~]# firewall-cmd --add-service=rpc-bind --permanent 
[root@localhost ~]# firewall-cmd --add-port=944/tcp --permanent 
[root@localhost ~]# firewall-cmd --add-port=944/udp --permanent 
[root@localhost ~]# firewall-cmd --add-port=945/tcp --permanent 
[root@localhost ~]# firewall-cmd --add-port=945/udp --permanent 
[root@localhost ~]# firewall-cmd --add-port=946/udp --permanent 
[root@localhost ~]# firewall-cmd --reload

    三. 配置NIS客户端

[root@  localhost ~]# yum -y install ypbind rpcbind
[root@  localhost ~]# ypdomainname nis.test 
[root@  localhost ~]# echo "NISDOMAIN=nis.test" >> /etc/sysconfig/network 
[root@  localhost ~]# vi /etc/hosts
10.168.10.71    srv01.nis.test  srv01
10.168.10.72    srv02.nis.test  srv02
10.168.10.73    srv03.nis.test  srv03
10.168.10.74    srv04.nis.test  srv04
10.168.10.75    srv05.nis.test  srv05
[root@  localhost ~]# authconfig \
--enablenis \
--nisdomain=nis.test \
--nisserver=srv01.nis.test \
--enablemkhomedir \
--update
[root@  localhost ~]# systemctl start rpcbind ypbind 
[root@  localhost ~]# systemctl enable rpcbind ypbind

附注：如果启用了SELinux，就需要添加一个规则，允许mkhomedir自动创建用户主目录

又附注： Wingdows 10 的SSH客户端很好用
