Centos8搭建配置nis域服務詳細步驟_Linux

作者：~槑~ ? 更新時間： 2021-12-02 編程語言

NIS 簡介

NIS，英文的全稱是network information service，也叫yellow pages。在Linux中，NIS是一個基于RPC的client/server系統，需要使用 RPC 服務。

RPC即Remote Procedure Call Protocol（遠程過程調用協議），RPCBIND用于取代舊版本中的portmap組件。簡單說，RPCBIND就是為了將不同服務與對應的端口進行綁定，以便支持機器間的相互操作。

網絡環境：

節點 主機
node1(nis主服務器) 192.168.10.222
node2(nis客戶機) 192.168.10.223

1.環境準備(兩個節點都要)

關閉防火墻

systemctl stop firewalld 
setenforce 0

添加主機名解析

vim /etc/hosts
192.168.10.222 node1 
192.168.10.223 node2

2.nis主服務器配置

?下載軟件包

yum -y install  rpcbind ypserv ypbind yp-tools

添加nis域名

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

開機自動掛載nis域名

[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

修改主配置文件限制權限

vim /etc/ypserv.conf
192.168.10.0/24:*:*:none   //給與該網段訪問權限
192.168.10.222:*:*:none    //給與該本機訪問權限
             :*:*:deny     //拒絕其他服務器

重啟服務

systemctl restart yppasswdd rpcbind ypserv 
systemctl enable  yppasswdd rpcbind ypserv

建立資料庫

[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...
Building /var/yp/skills.com/ypservers...
Running /var/yp/Makefile...
gmake[1]: Entering directory '/var/yp/skills.com'
Updating passwd.byname...
Updating passwd.byuid...
Updating group.byname...

gmake[1]: Leaving directory '/var/yp/skills.com'
 
localhost has been set up as a NIS master server.
 
Now you can run ypinit -s localhost on all slave server.
[root@localhost ~]#

新建nis賬戶

useradd nis1 -p123 
useradd nis2 -p123 
當主機發生了更改就cd到/var/yp make 
[root@localhost ~]# cd /var/yp/
[root@localhost yp]# make
gmake[1]: Entering directory '/var/yp/skills.com'
Updating passwd.byname...
Updating passwd.byuid...
Updating group.byname...
Updating group.bygid...
Updating netid.byname...
gmake[1]: Leaving directory '/var/yp/skills.com'
[root@localhost yp]#

重啟服務

systemctl restart yppasswdd rpcbind ypserv 
systemctl enable  yppasswdd rpcbind ypserv

3.nis客戶端設置?

?下載軟件包

yum -y install ypbind rpcbind yp-tools

添加nis域名

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

開機自動掛載nis域名

[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

編輯yp.conf文件，設置主服務。?

domain skills.com server 192.168.10.222

重啟服務

 systemctl restart ypbind rpcbind

?yptest查看是否加入成功

[root@localhost ~]# yptest

配置域用戶登陸

[root@localhost ~]# authselect select nis --force
Backup stored at /var/lib/authselect/backups/2021-12-13-09-34-52.8NFKZD
Profile "nis" was selected.
The following nsswitch maps are overwritten by the profile:
- aliases
- automount
- ethers
- group
- hosts
- initgroups
- netgroup
- networks
- passwd
- protocols
- publickey
- rpc
- services
- shadow
 
Make sure that NIS service is configured and enabled. See NIS documentation for more information.
 
[root@localhost ~]#

主服務器配置nfs，將home目錄共享。

[root@localhost yp]# vim /etx/exports
/home/ *(rw,sync)
[root@localhost yp]# exportfs -rv
exporting *:/home

客戶端掛載主服務器home目錄

systemctl restart nfs-server 
[root@localhost ~]# mount 192.168.10.222:/home/ /home/
[root@localhost ~]# df
Filesystem           1K-blocks    Used Available Use% Mounted on

192.168.10.222:/home  17811456 1644672  16166784  10% /home
[root@localhost ~]#

添加開機自動掛載主服務home目錄。

vim /etc/fstab
192.168.10.222:/home    /home                   nfs     defaults        0 0
[root@localhost ~]# mount -a 
[root@localhost ~]# df

devtmpfs                379852       0    379852   0% /dev

tmpfs                   399816    5688    394128   2% /run

到這nis配置完成。
