Today, I would like to talk to you about how to replace the CVM. Many people may not know much about it. In order to make you understand better, the editor summarized the following contents. I hope you can get something from this article.

In the process of website optimization, it is common to change the server. Due to various reasons, the current CVM may no longer meet or do not meet the needs of the current website, so you need to replace the CVM at this time.

The steps for the website to change the server correctly are as follows:

1. Before the transfer, the website backs up all the file data, including databases, pages, pictures and all programs, in order to avoid operational errors and lead to data loss.

2. Set the TTL of the domain name server to be very short. The TTL setting controls the caching time of the site, and setting it to a very short time can help ISP and search engines view domain name server information at any time without having to access the IP address in the cache.

3. Register the account leased by the new server. If there are a large number of websites, which belongs to the site group, you can choose the station group server, and you can bind the station group website to different IP, which is very conducive to SEO optimization.

4. Log in to the new server and upload the file. When all the files have been uploaded and can operate normally, change the domain name server and resolve the website to the new server IP address. At the same time, the website on the original server should also be kept running normally.

5. Check the log file of the website on the new CVM. When the search engine spider has started to visit the page on the new server, the website has been transferred successfully. Domain name resolution time is usually within 3 days, and just to be on the safe side, wait a few more days to make sure that all search engine spiders know that the site has been transferred to a new server and IP address.

6. When it is determined that the parsing process has been completed and there are no users and search engine spiders on the original server, then the original old server account can be closed and the whole server replacement process is completed.
