Redis集群部署一次面试的经历（redis集群部署面试题）

With the rapid development of Internet, the demand for distributed services is gradually increasing. Deploying Redis cluster is a very important job for most development engineers. The other day I went to an interview, and the interviewer particularly tested my knowledge about deploying Redis cluster.

First of all, I was asked to expln the topology of Redis cluster. I expounded the basic principles of Redis cluster and how the slave node uses automatic flover to ensure system redundancy at the same time. Then, the interviewer asked me to illustrate the process of deploying Redis cluster in detl. I described the following steps: first, install Redis on each node; second, configure each instance to form a cluster; and third, link each node of the cluster.

Apart from the common theory, the interviewer also asked me to describe the hidden steps in the Redis cluster deployment process. I pointed out the following hidden steps. First, Optimize the Redis configuration. Secondly, Configure a locking mechanism to ensure the validity of data replication. Thirdly, configure the monitoring mechanism, determine the alarm conditions and alarm alarm contacts in advance, and timely detect exceptions to ensure normal operation of the cluster. In addition, for the problem of cluster data, backup and migration must be considered.

Finally, with the above steps, I was able to expln the detls of Redis cluster deployment. With my careful explanation, the interviewer expressed satisfaction.

In summary, detly understanding the deployment process of Redis cluster and combining actual experience is very important. It will not only help us to perform the task more efficiently, but also help us get a job in the interview.
