Centos8搭建配置nis域服务详细步骤

systemctl stop firewalld 
setenforce 0

vim /etc/hosts
192.168.10.222 node1 
192.168.10.223 node2

yum -y install  rpcbind ypserv ypbind yp-tools 

[root@localhost ~]# nisdomainname skills.com 
vim /etc/sysconfig/network
NISDOMAIN skills.com

[root@localhost ~]# vim /etc/rc.d/rc.local
 touch /var/lock/subsys/local
/bin/nisdomainname skills.com
[root@localhost ~]# chmod 777 /etc/rc.d/rc.local 

vim /etc/ypserv.conf
192.168.10.0/24:*:*:none   //给与该网段访问权限
192.168.10.222:*:*:none    //给与该本机访问权限
             :*:*:deny     //拒绝其他服务器

systemctl restart yppasswdd rpcbind ypserv 
systemctl enable  yppasswdd rpcbind ypserv  

[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 the
list, type a <control D>.
        next host to add:  localhost
        next host to add:  
The current list of NIS servers looks like this:
 
localhost
 
Is this correct?  [y/n: y]  y
We need a few minutes to build the databases...

localhost has been set up as a NIS master server.
 
Now you can run ypini编程学习网t -s localhost on all slave server.

useradd nis1 -p123 
useradd nis2 -p123
