RHEL5 Install NIS

环境：
master,slave,client 均采用RHEL5
master:
hostname: master.atyu30.com 10.0.0.150
Slave:
hostname: slave.atyu30.com 10.0.0.160
Client:
hostname: client1.atyu30.com 10.0.0.170

Master:

1.安装NIS Server
# yum install ypbind
2.正名
# cat /etc/hosts
10.0.0.150              master.atyu30.com master
10.0.0.160              slave.atyu30.com slave
10.0.0.170              client1.atyu30.com client1

3.指定NISDOAMIN
# vi /etc/sysconfig/network
+ NISDOMAIN=master

4.生成NIS数据库
# /usr/lib/yp/ypinit -m

At this point, we have to construct a list of the hosts which will run NIS
servers.  master.atyu30.com 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 .
        next host to add:  master.atyu30.com
        next host to add:  
The current list of NIS servers looks like this:

master.atyu30.com

Is this correct?  [y/n: y]  y
We need a few minutes to build the databases...

master.atyu30.com has been set up as a NIS master server.

Now you can run ypinit -s master.atyu30.com on all slave server.

5.共享的资源
# vi /var/yp/Makefile
#NOPUSH=true(把这一行注释掉，缺省是不允许主动推的)
NOPUSH=false

6.授权slave
# vi /var/yp/ypservers
master.atyu30.com
＋slave.atyu30.com
7.启动NIS Server
#  /etc/init.d/portmap restart
#  /etc/init.d/ypbind restart
#  /etc/init.d/yppasswdd restart
8.测试
# yptest
Test 1: domainname
Configured domainname is "master"

Test 2: ypbind
Used NIS server: master.atyu30.com

Test 3: yp_match
WARNING: No such key in map (Map passwd.byname, key nobody)

Test 4: yp_first
user1 user1:$1$0yzHpbZd$IFk/llsLo6fg7yKfQsoYr/:500:500::/home/user1:/bin/bash

Test 5: yp_next

Test 6: yp_master
master.atyu30.com

Test 7: yp_order
0

Test 8: yp_maplist
group.bygid
netid.byname
protocols.byname
protocols.bynumber
passwd.byname
services.byname
hosts.byaddr
hosts.byname
rpc.bynumber
rpc.byname
services.byservicename
group.byname
mail.aliases
passwd.byuid
ypservers

Test 9: yp_all
user1 user1:$1$0yzHpbZd$IFk/llsLo6fg7yKfQsoYr/:500:500::/home/user1:/bin/bash
1 tests failed

9.添加启动项
#  chkconfig portmap 235 on
#  chkconfig ypbind 235 on
#  chkconfig yppasswdd on

Slave
1.安装NIS Server
# yum install ypbind ypserv
2.正名
# cat /etc/hosts
10.0.0.150              master.atyu30.com master
10.0.0.160              slave.atyu30.com slave
10.0.0.170              client1.atyu30.com client1

3.指定NISDOAMIN
# vi /etc/sysconfig/network
+ NISDOMAIN=master

4.启动NIS Server
#  /etc/init.d/portmap restart
#  /etc/init.d/ypbind restart
#  /etc/init.d/yppasswdd restart

5.与master同步数据
# /usr/lib/yp/ypinit -s master

6.添加启动项
#  chkconfig portmap 235 on
#  chkconfig ypbind 235 on
#  chkconfig yppasswdd on

Client
1.安装NIS Server
# yum install ypbind

2.正名
# cat /etc/hosts
10.0.0.150              master.atyu30.com master
10.0.0.160              slave.atyu30.com slave
10.0.0.170              client1.atyu30.com client1

3.指定NISDOAMIN
# vi /etc/sysconfig/network
+ NISDOMAIN=slave

4. # vi /etc/nsswitch.conf

passwd:     files nis
shadow:     files nis
group:      files nis
hosts:      files nis dns

5.# vi /etc/sysconfig/authconfig
USENIS=yes

6. # vi /etc/pam.d/system-auth
password    sufficient    pam_unix.so md5 shadow nis nullok try_first_pass use_authtok

7. # vi /etc/yp.conf

domain slave broadcast

如果想省方便4-7 可以采用authconfig-tui来一步完成

8.启动NIS
#  /etc/init.d/portmap restart
#  /etc/init.d/ypbind restart
#  /etc/init.d/yppasswdd restart

9.登录验证
