Microsoft Cluster service The MSCS failover function is implemented through redundancy in multiple computers connected to a cluster, each with a separate fault state. To achieve redundancy, you need to install applications on multiple servers in the cluster. However, at any one time, the application is online only on

OtherIf you want to convert a shard cluster to a replica set cluster, you need to dump the data and restore it back;If

case of failover, SAMB 3.0 also brings a new feature called "Witness Service" that allows users to quickly switch connections from the client to other devices in the cluster in the face of a hardware failure.Management functionsEach version of Windows Server 2012 is unified

in/etc/hosts on slave2. The configuration is as follows: Save and exit. In this case, we can ping both master and slave1; Finally, configure the ing between the host name and IP address in/etc/hosts on the master. The configuration is as follows: At this time, the ping command is used on the master to communicate with the slave1 and slave2 machines: It is found that the machines on the two slave nodes have been pinged. Finally, let's test the communication between the

First, modify the core-site.xml file of the Master, where the content of the file is: We changed the "localhost" domain name to "master ": In the same operation, open the slave1 and slave2 node core-site.xml and change the "localhost" domain name to "master ". Second, modify the master, slave1, slave2 mapred-site.xml file. Go to the mapred-site.xml file of the master node, change the localhost domain name to master, save and exit. Similarly, open the slave1 and slave2 node mapred-site.x

Most enterprises in the early IT infrastructure will consider a mix of infrastructure services and domain control roles such as DHCP deployment. This will not only save costs but also simplify management. But as the size of the enterprise expands and the IT infrastructure becomes more and more sophisticated, the mix of deployments can be limited in terms of rights management and usability. Separating the role server is definitely the best choice. Le
