NIS服务器的配置过程

以前在做实验的过程中总结和写的一些教程的一些资料，一直没时间发布到博客上面，五一到了，终于有点时间发布啦！关于Linux上面还会有RHCE系列的学习笔记发表

NIS需要的软件包：rpm -ivh ypserv-2.13-5.i386.rpm

NIS的配置文件：/etc/ypserv.conf NIS的守护进程：ypserv 1、按装rpm包 [root@cisco RPMS]# rpm -ivh ypserv-2.13-5.i386.rpm warning: ypserv-2.13-5.i386.rpm: V3 DSA signature: NOKEY, key ID db42a60e Preparing... ########################################### [100%] 1:ypserv ########################################### [100%] 2、开启time和time-udp服务，nis服务需要这两个服务的支持 [root@cisco RPMS]# chkconfig --list|grep time time-udp: off time: off daytime: off daytime-udp: off [root@cisco RPMS]# chkconfig time on [root@cisco RPMS]# chkconfig time-udp on [root@cisco RPMS]# service xinetd restart Stopping xinetd: [ OK ] Starting xinetd: [ OK ] 3、设定NIS域名 [root@cisco RPMS]# nisdomainname nis-abc [root@cisco RPMS]# vi /etc/rc.d/rc.local #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local nisdominname nis-abc "/etc/rc.d/rc.local" 8L, 242C [root@cisco RPMS]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=localhost.localdomain NISDOMAIN=nis-abc :wq 4、编辑主配置文件 [root@cisco ~]# vi /etc/ypserv.conf 127.0.0.0/255.255.255.0 : * : * : none 192.168.20.0/255.255.255.0 : * : * : none * : * : * : deny 5、设置对NIS客户端主机的安全访问  cat /var/yp/securenets host 127.0.0.1 255.255.255.0 192.168.20.0 6.、创建账号和密码，用来验证 [root@cisco ~]# useradd cisco [root@cisco ~]# passwd cisco Changing password for user cisco. New UNIX password: BAD PASSWORD: it is too simplistic/systematic Retype new UNIX password: passwd: all authentication tokens updated successfully. 7、启动服务 [root@cisco ~]# service ypserv start Starting YP server services: [ OK ] 8、构建NIS的数据库文件 [root@cisco ~]# /usr/lib/yp/ypinit -m At this point, we have to construct a list of the hosts which will run NIS servers. cisco 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: cisco next host to add: The current list of NIS servers looks like this: cisco Is this correct? [y/n: y] We need a few minutes to build the databases... Building /var/yp/nis-abc/ypservers... gethostbyname(): Resource temporarily unavailable Running /var/yp/Makefile... gmake[1]: Entering directory `/var/yp/nis-abc' 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/nis-abc' cisco has been set up as a NIS master server. Now you can run ypinit -s cisco on all slave server. NIS客户端的配置过程 NIS客户端需要的软件包：ypbind-1.17.2-3 yp-tools-2.8-7 NIS客户端的配置文件：/etc/yp.conf NIS客户端的守护进程：ypbind 1、查看是否安装了RPM包 [root@localhost ~]# rpm -qa |grep ^yp ypbind-1.17.2-3 yp-tools-2.8-7 2、设置NIS的域名 [root@cisco RPMS]# nisdomainname nis-abc [root@cisco RPMS]# vi /etc/rc.d/rc.local #!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local nisdominname nis-abc "/etc/rc.d/rc.local" 8L, 242C [root@cisco RPMS]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=localhost.localdomain NISDOMAIN=nis-abc 3、设置客户机的主配置文件 [root@localhost ~]# vi /etc/yp.conf # generated by /sbin/dhclient-script domain nis-abc server cisco 4、设置主机的HOSTS文件 [root@localhost ~]# vi /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost 192.168.20.1 cisco 5、[root@localhost ~]# vi /etc/nsswitch.conf passwd: files nis shadow: files nis group: files nis 6、启动服务ypbind服务程序 [root@localhost ~]# service portmap status portmap (pid 1696) is running... [root@localhost ~]# service ypbind start Binding to the NIS domain: [ OK ] Listening for an NIS domain server.. 7、验证 [root@localhost ~]# yptest Test 1: domainname Configured domainname is "nis-abc" Test 2: ypbind Used NIS server: cisco Test 3: yp_match WARNING: No such key in map (Map passwd.byname, key nobody) Test 4: yp_first cisco cisco:$1$hvFanF6I$GB4qhFjJjfF2YMlUaJVa40:500:500::/home/cisco:/bin/bash Test 5: yp_next WARNING: Internal NIS error (Map passwd.byname) Test 6: yp_master cisco Test 7: yp_order 1243581051 Test 8: yp_maplist protocols.byname ypservers rpc.bynumber hosts.byname netid.byname hosts.byaddr passwd.byuid passwd.byname group.byname rpc.byname group.bygid services.byservicename services.byname mail.aliases protocols.bynumber Test 9: yp_all cisco cisco:$1$hvFanF6I$GB4qhFjJjfF2YMlUaJVa40:500:500::/home/cisco:/bin/bash 2 tests failed [root@localhost ~]# ypwhich cisco [root@localhost ~]# ypwhich -x Use "ethers" for map "ethers.byname" Use "aliases" for map "mail.aliases" Use "services" for map "services.byname" Use "protocols" for map "protocols.bynumber" Use "hosts" for map "hosts.byname" Use "networks" for map "networks.byaddr" Use "group" for map "group.byname" Use "passwd" for map "passwd.byname" [root@localhost ~]# ypcat -x Use "ethers" for map "ethers.byname" Use "aliases" for map "mail.aliases" Use "services" for map "services.byname" Use "protocols" for map "protocols.bynumber" Use "hosts" for map "hosts.byname" Use "networks" for map "networks.byaddr" Use "group" for map "group.byname" Use "passwd" for map "passwd.byname"
