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：

1.环境准备(两个节点都要)

关闭防火墙

systemctl stop firewalld

setenforce 0添加主机名解析

vim /etc/hosts

192.168.10.222 node1

192.168.10.223 node2


2.nis主服务器配置

 下载软件包

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开机自动挂载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权限

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     //拒绝其他服务器重启服务

systemctl restart yppasswdd rpcbind ypserv

systemctl enable  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 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…

Updating group.bygid…

Updating hosts.byname…

Updating hosts.byaddr…

Updating rpc.byname…

Updating rpc.bynumber…

Updating services.byname…

Updating services.byservicename…

Updating netid.byname…

Updating protocols.bynumber…

Updating protocols.byname…

Updating mail.aliases…

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账户

useradd nis1 -p123

useradd nis2 -p123

当主机发生了更改就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]# 重启服务

systemctl restart yppasswdd rpcbind ypserv

systemctl enable  yppasswdd rpcbind ypserv  


3.nis客户端设置 

 下载软件包

yum -y install ypbind rpcbind yp-tools添加nis域名

[root@localhost ~]# nisdomainname skills.com

vim /etc/sysconfig/network

NISDOMAIN skills.com开机自动挂载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 编辑yp.conf文件，设置主服务。 

domain skills.com server 192.168.10.222重启服务

systemctl restart ypbind rpcbind  yptest查看是否加入成功

[root@localhost ~]# yptest

Test 1: domainname

Configured domainname is “skills.com”

Test 2: ypbind

Use Protocol V1: Used NIS server: 192.168.10.222

Use Protocol V2: Used NIS server: 192.168.10.222

Use Protocol V3:

ypbind_nconf:

        nc_netid: udp

        nc_semantics: 1

        nc_flag: 1

        nc_protofmly: ‘inet’

        nc_proto: ‘udp’

        nc_device: ‘-‘

        nc_nlookups: 0

ypbind_svcaddr: 192.168.10.222:740

ypbind_servername: 192.168.10.222

ypbind_hi_vers: 2

ypbind_lo_vers: 2

Test 3: yp_match

WARNING: No such key in map (Map passwd.byname, key nobody)

Test 4: yp_first

[root@localhost ~]# 配置域用户登陆

[root@localhost ~]# authselect select nis –force

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 ~]# 主服务器配置nfs，将home目录共享。

[root@localhost yp]# vim /etx/exports

/home/ *(rw,sync)

[root@localhost yp]# exportfs -rv

exporting *:/home客户端挂载主服务器home目录

systemctl restart nfs-server

[root@localhost ~]# mount 192.168.10.222:/home/ /home/
