这篇文章给大家分享的是有关Centos8如何搭建配置nis域服务的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
NIS 简介
NIS，英文的全称是network information service，也叫yellow pages。在Linux中，NIS是一个基于RPC的client/server系统，需要使用 RPC 服务。
RPC即Remote Procedure Call Protocol（远程过程调用协议），RPCBIND用于取代旧版本中的portmap组件。简单说，RPCBIND就是为了将不同服务与对应的端口进行绑定，以便支持机器间的相互操作。
网络环境：
| 节点 | 主机 |
| node1(nis主服务器) | 192.168.10.222 |
| node2(nis客户机) | 192.168.10.223 |
1.环境准备(两个节点都要)
关闭防火墙
systemctl< /span > stop< /span > firewalld< /span >
setenforce< /span > 0< /span >
添加主机名解析
vim< /span > /etc/hosts < /span >
192.168< /span >.10< /span >.222< /span > node1< /span >
192.168< /span >.10< /span >.223< /span > node2< /span >
2.nis主服务器配置
下载软件包
yum< /span > -y install rpcbind ypserv ypbind yp-tools
添加nis域名
[root@localhost ~] # nisdomainname skills.com
vim /etc/sysconfig/network
NISDOMAIN skills.com
开机自动挂载nis域名
[root@localhost ~< /span >] # vim /etc/rc.d/rc.local
touch /var< /span >/lock< /span > /subsys/local
/bin/nisdomainname skills.com
[root@localhost ~< /span >] # chmod 777 /etc/rc.d/rc.local
修改主配置文件限制权限
vim< /span > /etc/ypserv .conf< /span >
192.168< /span >.10< /span >.0< /span > /24 :*:*:none< /span > // 给与该网段访问权限< /span >
192.168< /span >.10< /span >.222< /span >:*:*:none< /span > // 给与该本机访问权限< /span >
:*:*:deny< /span > // 拒绝其他服务器< /span >
重启服务
systemctl restart yppasswdd rpcbind ypserv
systemctl enable < /span > yppasswdd rpcbind ypserv
建立资料库
[root@localhost ~] # /usr/lib64/yp/ypinit -m
At this point, we have to construct a list of the hosts which will run NIS
servers. localhost is in the list of NIS server hosts. Please continue to add
the names for the other hosts, one per line. When you are done with< /span > the
list< /span >, type < /span > a <control D>.
next< /span > host to< /span > add< /span >: localhost
next< /span > host to< /span > add< /span >:
The current< /span > list< /span > of< /span > NIS servers looks like< /span > this:
localhost
Is< /span > this correct? [y /n : y] y
We need a few minutes< /span > to< /span > build< /span > the databases...

重启服务
systemctl restart yppasswdd rpcbind ypserv
systemctl enable < /span > yppasswdd rpcbind ypserv
3.nis客户端设置
下载软件包
yum< /span > -y install ypbind rpcbind yp-tools
添加nis域名
[root@localhost ~] # nisdomainname skills.com
vim /etc/sysconfig/network
NISDOMAIN skills.com
开机自动挂载nis域名
[root@localhost ~< /span >] # vim /etc/rc.d/rc.local
touch /var< /span >/lock< /span > /subsys/local
/bin/nisdomainname skills.com
[root@localhost ~< /span >] # chmod 777 /etc/rc.d/rc.local
编辑yp.conf文件，设置主服务。
domain< /span > skills< /span >.com< /span > server< /span > 192.168< /span >.10< /span >.222< /span >
重启服务
systemctl< /span > restart ypbind rpcbind
yptest查看是否加入成功
