At present, many enterprise websites are mainly built on virtual hosts, because Virtual host The cost of building a website is relatively low, which can also meet the daily needs of enterprise websites. However, you must carefully consider before selecting a virtual machine supplier to avoid problems later. However, there are always some webmaster virtual host leasing problems, leading to the normal operation of the website is also affected to some extent. If there is a problem with the virtual host, some webmasters will choose to change to another one. At this time, site migration is required. What process should be followed when changing their own virtual host? Many people don't know much about this, so today Neutrino network Let's take a look. 1、 Do a good job of early inspection
The virtual machine should not be replaced randomly as far as possible, but when it really needs to be replaced, first check whether the virtual machine IP to be replaced is secure, whether there are other illegal websites, whether it is blocked by the search engine, etc. The insecure and unreliable virtual machine IP cannot be migrated to the virtual machine.
2、 Backup the website
It is important to back up the database. Before migrating the site, you must first back up the database. If the website administrator is not very clear about the directory structure, he can spend more time backing up the entire site, because once an error occurs, the impact on the site will be devastating.
3、 Keep the original site for at least 7 days
To prepare for site migration, you must keep the content of the original site for at least 7 days in advance. The website does not need to be updated in these days, so that the search engine can still use the IP address of the original site to access the content of the site. Because many search engines cache DNS, if the migration site immediately deletes all data from the original site, a large number of 404 error pages may appear. So after the search engine updates the DNS cache, you must ensure that you delete data from the original site.
4、 Migration time is selected when users visit fewer sites
Generally speaking, early morning is an excellent time for website migration. If you don't want to or can't stay up late, you'd better start working earlier, such as 6-7 in the morning. Please note that you should never change between 2-5 p.m. and 8-11 p.m., because these two periods are the peak time for Internet access and also the time when many websites have the most traffic.
5、 Keep the original virtual host site
If you use FTP to migrate to a new virtual host, you need to manually confirm whether the website can be accessed normally. Generally, the virtual host provider will provide a free three-level domain name to test the website to be migrated. If the test is OK, you can start to re analyze the domain name.
6、 Resolve domain name A record
The method to set the domain name resolution: member login → domain name management → click the domain name to be resolved → domain name resolution service → set a new resolution address, that is, modify the domain name A record. After the "domain name control panel" is resolved, the domain name on the website control panel is quickly reset, and the new virtual host can be successfully accessed in about 2 hours.
