NISサーバー構築2009/06/14 |
| 各サーバーのネットワークでユーザーのアカウント情報を共有できるようにNISサーバーを構築します。 小・中規模であればこのNISは有効ですが、大規模なサブネットで使用する場合や、Windowsとのユーザー共有を行う場合は LDAPを使用してください。 |

[root@dlp ~]# yum -y install ypserv [root@dlp ~]# ypdomainname srv.world # NISドメイン指定 [root@dlp ~]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=ns.srv.world NISDOMAIN=srv.world # 最終行へ追記 [root@dlp ~]# vi /var/yp/Makefile # MERGE_PASSWD=true|false MERGE_PASSWD= false # 42行目：変更 # # MERGE_GROUP=true|false MERGE_GROUP= false # 46行目：変更 # # 117行目：追記 all: passwd shadow group hosts rpc services netid protocols[root@dlp ~]# vi /var/yp/securenets host 127.0.0.1 255.255.255.0 192.168.0.0 [root@dlp ~]# /etc/rc.d/init.d/rpcbind start Starting rpcbind: [ OK ] [root@dlp ~]# /etc/rc.d/init.d/ypserv start Starting YP server services: [ OK ] [root@dlp ~]# /etc/rc.d/init.d/yppasswdd start Starting YP passwd service: [ OK ] [root@dlp ~]# chkconfig rpcbind on [root@dlp ~]# chkconfig ypserv on [root@dlp ~]# chkconfig yppasswdd on [root@dlp ~]# /usr/lib64/yp/ypinit -m # NISデータベース更新 At this point, we have to construct a list of the hosts which will run NIS servers. dlp.srv.world 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: dlp.srv.world next host to add: # Ctrl + D キーを押す The current list of NIS servers looks like this: dlp.srv.world Is this correct? [y/n: y] y We need a few minutes to build the databases... Building /var/yp/srv.world/ypservers... gethostbyname(): Success Running /var/yp/Makefile... gmake[1]: Entering directory `/var/yp/srv.world' Updating passwd.byname... Updating passwd.byuid...

Now you can run ypinit -s dlp.srv.world on all slave server. # 以降、新しくユーザーを追加した場合は、以下のようにしてNISデータベースの更新もする [root@dlp ~]# cd /var/yp [root@dlp yp]# |
