Today, I will talk to you about whether to restart the CVM on a regular basis. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.

Yes, because the website is generally online 24 hours a day, and the CVM needs to run continuously, so errors of one kind or another are inevitable. The common solution is to restart the server.

A normal server restart can remove memory fragments, re-optimize the software call level, interrupt useless network ports, and so on, which has certain benefits for relieving CPU pressure and server maintenance.

General reasons for server restart:

Active restart by technical managers due to equipment maintenance and update, computer room deployment or other special circumstances

Forced restart due to power supply (undervoltage, overload, fluctuation), vibration, hardware quality (thermal sensitivity and anti-interference), damage to DirectX files, system imperfections or bottlenecks, viruses, dust, poor heat dissipation, etc.

Due to the restart caused by the server downtime event, as the server hardware is overloaded all the year round, it is easy to have downtime over a long period of time. The common solution is to restart regularly to alleviate the hardware pressure and keep the server performance longer.

Because the server runs for too long, it will cause a lot of redundant DLL programs, resulting in the slow running speed of the system. The restart of the server will restore the website space to the default loading state and improve the response speed of the system.

However, abnormal CVM restart can also bring some harm, because the use of shutdown or reboot is equivalent to power off, there may be the risk of data loss or system damage.

In particular, when reading and writing to the hard disk, a sudden power outage or a forced restart will cause great damage to the hard disk: if it is light, it will lose the data, resulting in a logical bad path; if it is heavy, it may damage the hard disk head and cause a physical bad path. Therefore, under normal circumstances, it is recommended that users use remote login to shut down or restart normally, and if they really cannot log in, use the server restart feature.

After reading the above, do you have any further understanding of whether to restart the CVM regularly? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
