Server Configuration
1. Install and start necessary services
Rpm-ivh ypserv-xxx.rpm
Chkconfig time on
Chkconfig time-udp on
Service xinetd restart
 
2. Create and add a domain name
Host Name
Hostname ypserv
Vi/etc/sysconfig/network
HOSTNAME = ypserv
Vi/etc/hosts
 
Domain
Nisdomainname nistest
Echo '/bin/nisdomain nistest'>/etc/rc. d/rc. local
Echo 'nisdomain = nistest '>/etc/sysconfig/network

3. Modify the ypserv. conf configuration file.
Ypserv. conf
You can set access control for the authenticated database in the configuration file.
Vi/etc/ypserv. conf
Comment out the last two lines that allow all programs to access
192.168.63.0/255.255.255.0: *: none
127.0.0.0/255.255.255.0: *: none
*: Deny
 
4. Create a securenets Security Configuration File
The securenets file is used to control access to the NIS client host.
The securenets file needs to be created manually
Vi/var/yp/securenets
Host 127.0.0.1
255.255.255.0 192.168.63.0

5. Start the NIS Server
The NIS server requires the support of the portmap service and starts the ypserv and yppasswdd services.
Service portmap status is enabled by default.
Service ypserv start
Service yppasswdd start
