How to solve the virtual host outage? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

There are a variety of reasons for virtual host downtime. It is recommended to contact the cloud service provider as soon as possible to determine what causes it. In general, cloud service providers are relatively aware of the reasons for virtual host downtime, such as virtual host space is full, virtual host has violation information, virtual host server failure and so on.

Stability is an important index to test the virtual host, and whether it can run stably for a long time is a necessary quality for a qualified virtual host. Of course, in the process of using the virtual host, we still can not avoid all kinds of failures, such as downtime. So what do we need to do when there is a downtime?

1. Contact the cloud service provider

Contact the cloud service provider to determine the cause of the outage and, if conditions permit, to resume operation as soon as possible.

2. Troubleshooting the cause of downtime

The server is down, usually

A, the virtual host space is full: the space is full, it is easy to cause the virtual host to go down and the website cannot be accessed. At this point, we need to upgrade the space size, or directly upgrade the virtual host, using a higher configuration of virtual host or cloud server.

B. DNS server failure: compared with the CVM, the DNS server of the virtual host is less stable and prone to problems, such as being attacked, parsing errors, etc., and the virtual host is prone to downtime. It is recommended to choose several more DNS servers, generally 6 can be selected.

C, the virtual host is attacked: when the virtual host is attacked by ddos attack, CC attack, etc., the virtual host will be down. Although the virtual host has a certain security defense capability, it is much worse than the cloud server as a whole. Once a website is attacked, the entire server is easily implicated, causing other virtual hosts to have network problems, such as downtime. This kind of problem needs to be dealt with by cloud service providers.

D. Illegal information on the virtual host: when illegal or illegal information occurs on the website, it will be shut down and downtime will occur. If it is such a problem, delete the relevant information as soon as possible, and consult the cloud service provider and relevant departments on how to apply for recovery.

In addition to the above problems, there are program problems, network problems, equipment failures and other factors, which need to be investigated one by one. In the event of virtual host downtime, do not panic, calm down, in order to quickly solve the problem.

After reading the above, have you mastered how to solve the problem of virtual host downtime? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
