Parent topic: Preparing Exalogic for an Enterprise Deployment
As an Exalogic Administrator, you must set up the system for cloud users.
Note:
As part of the Exalogic installation process, the installer is required to validate the newly configured system. Therefore, some of the following steps might have been already executed. For example, Exalogic Guest Base Template (EGBT) may have been downloaded, imported and registered in Enterprise Manager Ops Center.Also see Task Overviews and Basic Concepts in Oracle Exalogic Elastic Cloud Administrator’s Guide. Refer to the Oracle Exalogic Elastic Cloud Administrator’s Guide for the following sections:
Getting Started With Cloud Administration 5-1: Consideration for Creating vServers
This topic provides a step-by-step illustration of how to setup and configure Exalogic virtual environment to provide an NIS environment comprised of MASTER/SLAVE servers and NIS clients.
Exalogic environment utilizes NFS4 and is connected to a centralised user directory, and it is necessary to configure a network Information System (NIS) environment. NIS allows you to create a master list of users which can then be granted access to various servers. It removes the need to create individual user accounts on servers.
For a user to log into a system through a NIS account, the server has to be configured to allow users to use the NIS service. You can refer to Configuring a Host. If there is another Master NIS server and there are several Slave NIS servers then the failure of one does not prevent users to log in. You have the option of creating a NIS service on the Exalogic appliance. If your Exalogic appliance were to be the master and the rack went down you can be prevented from creating new users.
If the environment allows you to contact an external NIS master from slaves located inside the rack, it is recommended to create the NIS master outside the rack and have the VMs in the rack be slaves to it. If this is not possible, when you bring up the rack you will need to disable the NIS service on the ZFS, bring up the IFS appliance, start the NIS VMs, and then enable the NIS service on the ZFS.
If desired LDAP authentication can be used instead of NIS. For the purposes of this guide we will assume that NIS is being used.
Following sections provide the detailed steps for configuring NIS in an Exalogic virtual environment.
Follow the detailed steps for configuring NIS in Exalogic environment.
If you are placing the NIS server into a virtual server then create a LARGE vServer, which has IPoIB-vServer-shared-storage and Client Access EoIB networks attached.
If you are configuring NIS for an Exalogic physical environment, then the NIS server should be added to the compute nodes directly.
Verify that you have the yp rpm’s installed on NIS vServers/Compute Nodes.
Create directory /etc/yum.repos.d
Run the command for downloading the yum repository:
wget http://public-yum.oracle.com/public-yum-el5.repo
Run yum install ypserv
command to install YP serv on NIS VMs.
If you are placing your NIS server into vServers then create a large vServer which is connected to the Client EoIB network and the Storage IPoIB network. For details refer to Creating a vServer.
Note:
If you are configuring a corporate NIS, then it is recommended that the NIS Master and Slave reside on different hosts, in different Exalogic racks or split between an external host and the external rack. This ensures that the failure of an Exalogic appliance does not impact the organizations ability to use NIS.This topic provides basic information on LDAP authentication.
If you want to use the LDAP authentication rather than NIS you can refer to Oracle Exalogic Elastic Cloud - Setting Up LDAP Service for NFSv4.
Exalogic instrumentation refers to tools that help collect, inform, diagnose, or automate configuration or transactional data.
A Master Note On Exalogic Instrumentation , of all of the currently available instrumentation summarizes these tools. Exalogic Kinetic Infrastructure Tools (EKIT) is a collection of tools that simplify, automate and standardize various infrastructure lifecycle management activities on an virtualized Exalogic rack running Linux. These tools can be used to create custom scripts that can automate many Exalogic lifecycle tasks. Refer to the master note on Exalogic Kinetic Infrastructure Tools (EKIT) for additional information.
Exalogic Lifecycle (ELLC) Tools automate lifecycle operations for Oracle Exalogic systems. Refer to the master note on Exalogic Lifecycle Toolkit Releases for additional information on Exalogic Lifecycle (ELLC) Tools.
