Fail-over cluster

Overview

This chapter focuses on building a Windows failover cluster

Environment:

Domain server: Windows Server R2 sp1,192.168.2.10

CLU11, Windows Server R2 SP1, 192.168.2.11

CLU12, Windows Server R2 SP1, 192.168.2.12

CLU13, Windows Server R2 SP1, 192.168.2.13

Note: Three PCs to build a cluster need to join the domain, three PC operating system must be the same, the IP address needs to be a network segment, if you do not want to configure the process of trouble finally do not make unnecessary configuration changes, keep three computers consistent.

Installing Failover Services

This step needs to be performed once on all three computers.

1. Open Server Manager-right-click Function-Add Features

2. Click Install to

Create a cluster

Three computers after the failover service is installed, select one of the computers to open the failover cluster

1. Management Tools-Failover clustering

2. Click Next

3. Click Browse to select a machine to join the cluster

4. Configure the validation test, which verifies that the configuration of the server joining the cluster meets the requirements and allows the next step only if the requirements are met.

5. Click Next

6. Select Run all tests-click Next

7. Click Next

8. Verify the pass, click Finish

9. Enter the cluster name and the cluster Web site address, where the network address is configured as 192.168.2.100

10. Click Next until complete

11. Configure cluster Quorum settings

12. Click Next

13. Select a majority node

14. Click Next

15. Click Finish

16. Open the domain controller and see the cluster cluster you just created under the computer files

Summary

There are a number of issues that may arise during the configuration of the cluster, which requires a cool thought, or, as mentioned earlier, the configuration of the servers that need to join the cluster must be consistent so that the probability of failure to pass is low or there are various problems.
