Naming and Directory Services (DNS, NIS, and LDAP)

To use ypinit to build a fresh set of NIS maps on the master server, do the following.▼How to set up the master server using ypinit1. On the master server, become superuser or assume an equivalent role.Roles contain authorizations and privileged commands. For more informationabout roles, see “Using Role-Based Access Control (Tasks)” in System AdministrationGuide: Security Services.2. Copy the contents of the nsswitch.files file to the nsswitch.conf file.# cp /etc/nsswitch.files /etc/nsswitch.conf3. Edit the /etc/hosts or /etc/inet/ipnodes file to add the name and IPaddress of each of the NIS servers.4. Build new maps on the master server.# /usr/sbin/ypinit -m5. When ypinit prompts for a list of other machines to become NIS slave servers,type the name of the server you are working on, along with the names of yourNIS slave servers.6. When ypinit asks whether you want the procedure to terminate at the firstnonfatal error or continue despite nonfatal errors, type y.When you choose y, ypinit exits upon encountering the first problem; you canthen fix it and restart ypinit. This is recommended if you are running ypinit forthe first time. If you prefer to continue, you can try to manually fix all problemsthat occur, and then restart ypinit.Note – A nonfatal error can appear when some of the map files are not present. Thisis not an error that affects the functionality of NIS. You might need to add mapsmanually if they were not created automatically. Refer to “Default NIS Maps”on page 72 for a description of all default NIS maps.7. ypinit asks whether the existing files in the /var/yp/domainname directory canbe destroyed.This message is displayed only if NIS has been previously installed.8. After ypinit has constructed the list of servers, it invokes make.This program uses the instructions contained in the Makefile (either the defaultone or the one you modified) located in /var/yp. The make command cleans anyremaining comment lines from the files you designated. It also runs makedbm onthe files, creating the appropriate maps and establishing the name of the masterserver for each map.86 System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP) • January 2005
