Changing the server or changing the host, is a lot of webmaster will encounter problems. Change the server roughly has the following kinds of situation: the on-line choice Server is more urgent, after the on-line feeling is not suitable; server type is incompatible with program; database compatibility problem; The original server could not meet the requirements after the website was developed for some time. Of course, there are other reasons, the replacement server for the new station is more common.

My site, from the on-line after the two servers changed, the approximate reason is these. For the first time, the site was parked for nearly two hours. This time, I learned my lesson, prior to the steps of the analysis and planning, the results of the site only closed more than 10 minutes, compared to the original shortened one hours, do not underestimate this one hours, for the site, may have dozens of users every minute visit, which may produce customers, search engines are not necessarily when suddenly visit. Do the site to start from the details, so I think this consideration is worthwhile. Below I put my experience and steps to say.

First of all, to change the server or host before the trial, the general server provider has a trial service, in order to avoid replacing again, the proposal first trial, trial no problem, then determine whether to replace. Of course, in the trial, you can not resolve the domain name to the trial server, the resolution of a two-level domain name.

Second, it is critical that you plan your steps. We know that to replace the server, you need to do these things: backup programs and data, upload programs, import database, reparse domain name, domain binding, configuration database, the original server content cleanup, etc., these work, there are many steps need to close the site. Although it looks a lot, but as long as the plan well and time, can make work orderly and shorten 11518.html "> website shutdown time." My practice: First the program and data back out, and then contact the service provider to provide new space name and password, so that the program can upload and import the database, and then configure the database, and the space required to do the configuration. During this period, because the original server can also use, domain name resolution has not changed, so the site can be normal access. Next, you need to close the site to do: Resolve the domain name to the new IP address, the domain name rebind. At this time the site can not be accessed, but after the reparse and binding, generally after a few minutes up to more than 10 minutes, the new server can be accessed. In this waiting time, the original server content can be cleaned up. So the whole process down, the site can be closed only for a short time.

The last thing to be reminded is that when choosing a server for the first time, consider trying to be as comprehensive as possible and avoid replacing it. This change of the server's steps and ideas, in fact, it is also very simple, as long as they carefully consider it can make the right steps to choose, but as a rookie, as a new webmaster, I think there will be some people need these experiences, write out for the new webmaster like me for reference.
