How to solve the problem when the CVM goes down? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The CVM is the carrier of data and websites. If there is a problem with the server, the data and websites placed on it will also be affected. Let's take a look at the causes of server downtime. And what should we do if the Ali Cloud server goes down?

Generally speaking, the reasons for downtime are:

1. Server performance reasons. Among the performance problems, the most common reason for server downtime is poor SQL, but it is not certain that this is the case. There are other possibilities, for example, some problems are caused by server Bug or incorrect behavior.

2, the reason of the running environment, if it is the running environment problem, then the most common is that the disk space is exhausted.

3, the cause of data loss or corruption, data loss is generally caused by the wrong operation of drop table, and always with the problem of lack of available backups.

4. The reason for replication is that if it is a replication problem, it is usually caused by the inconsistency between master and backup data.

When we find out the cause of the cloud host downtime, how can we solve it?

1. After discovering that the server is down, contact Aliyun's after-sales customer service or technology to solve the related problems in time, because maybe a short downtime will bring you heavy losses.

2. Be prepared for precautions. You can run two site spaces at the same time, storing the same content, and when one has a problem, you can immediately enable the other.

CVM is strong and stable, with a resource pool of more than 1000 CVMs, which perfectly supports hot migration. 4 copies of data from each CVM are retained, plus different machine backups are added, making the data safe and secure.

This is the end of the answer on how to solve the problem when the CVM crashes. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more relevant knowledge.
