搭建NIS

Master Server 端:

yum install -y ypserv rpcbind yp-tools ypbind
nisdomainname siton                                                                       #設置域名
vi /etc/sysconfig/network                                                               #永久設置域名
	NISDOMAIN=siton
	YPSERV_ARGS="-p 1011"                                                            #可省略
vi /etc/ypserv.conf                                                                              #根據需求修改相應規則
	dns: no
	*       : * : * : none
vi /etc/sysconfig/yppasswdd                                                        #將 yppasswdd 啓動在固定端口，可省略
	YPPASSWDD_ARGS="--port 1012"
systemctl start ypserv
systemctl start rpcbind
systemctl start yppasswdd.service
systemctl enable yppasswdd.service
systemctl enable rpcbind
systemctl enable ypserv
useradd -m -s /bin/bash nisuser                                     #新建 nis 用戶,以 nisuser 爲例
passwd nisuser
/usr/lib64/yp/ypinit -m                                                       #初始化 nis 服務器和映射表
cd /var/yp
make                                                                                          #更新 nis 賬戶和資料庫
vi /var/yp/Makefile                                                               #開啓 slave 服務推送
	NOPUSH=false
vi /var/yp/ypservers                                                            #加入 slave 節點的主機名
	node1
	node2
systemctl start ypxfrd
systemctl enable ypxfrd

Slave Server 端:

yum install -y ypserv rpcbind yp-tools ypbind
nisdomainname siton
vi /etc/sysconfig/network
	NISDOMAIN=siton
	YPSERV_ARGS="-p 1011"
vi /etc/ypserv.conf
vi /etc/sysconfig/yppasswdd
/usr/lib64/yp/ypinit -s node1                                                          #同步 Master 的源數據庫

客戶端:

yum install yp-tools ypbind -y
nisdomainname siton
vi /etc/sysconfig/network
	NISDOMAIN=siton
	YPSERV_ARGS="-p 1011"
