A lot of friends asked the site to develop to a certain extent, the original space or server performance is not enough, upgrade to a higher configuration of space or server will have an impact?

Here, I personally to tell you that there is an impact, if you just change the server has little impact, but if you have changed the IP, see the actual situation will have or large or small impact. If your replacement server or space has not been configured in time, resulting in server instability, please your condolences, the impact is really big ah.

March 19, I was responsible for the management of 2 Web sites finally developed to the stage can be Chine, ready to migrate to a new IDC server in Jiangxi.

Case 1: Youku 123 Home http://www.***.com

On the evening of March 20, 2011, the migration workflow is as follows:

(1) The domain name of godaddy registered again resolves to the IP on the new server.

(2) on the original server packaging Youku 123 Web site of the MySQL database, Web site program files.

(3) Copy the compressed package to another domain name of the Web site directory, to the new server download and unzip.

(4) To IIS new Web site to the program directory, set the directory permissions.

(5) GoDaddy domain name resolution one hours after the success, OK, open Youku 123 website home page. Well, you can open it.

(6) Login site backstage, rely on, tragedy, login, check found that the original is php5.3.6 not configured well, need to use fastcgi support.

After a day and a night to finally configure the server, all the functions of the website program can be normal use, the next day, the site's traffic changes are not small, and even the flow has risen, the third day, the tragedy continues to occur, Baidu and Google's flow under 3,000 feet, suddenly fell from 10000ip to 3000ip, fourth days, fifth days, Day Sixth ... The decline, to now only have more than 2000 IP. Check the Web service log, Baidu and Google's spider activity record at the same time greatly reduced, than before moving at least 10 points down to one.

After analysis, it should be the process of moving too careless, resulting in the site has a process of time access anomalies, leading to Baidu and Google at the same time the right to decline.

Picture example:

Case 2: After the first web site to learn from the experience, continue to move the second site-Guangxi ASEAN Dotcom March 23, 2011 Night, Migration workflow, steps to readjust:

(1) on the original server packaging Guangxi ASEAN dotcom database, Web site program files.

(2) Download the compressed package to the new server.

(3) New test domain name is opened. xxxxx。 COM, to help set up IIS to create a new site, unzip the Web site program to the site.

(4) repeatedly test the Guangxi ASEAN Dotcom web site procedures, until there is no error.

(5) The original server of Guangxi ASEAN dotcom Program Files and IIS domain name intact.

(6) Domain name reparse to the new server IP, one hours after the automatic transfer resolution success.

(7) The average daily to do outside the chain between 30 to 50.

The next day, the site traffic declined slightly, the third day continued Baidu, Google traffic decline, the fourth day to restore the original level, the fifth day continues normal. Spider activity also from a slight decline to restore the normal level before moving. Picture Example (Note: This site is less than One-third of the normal weekend traffic, so the number of weekends in the figure is normal):

Practice of true knowledge, only through the practice of the people really can experience the taste, and finally summed up, hoping to give later learners can provide a point of help:

(1) Moving process, do not forget to increase the strength of the chain to do a little more than usual to do some high-quality outside the chain.

(2) When changing the server, it is necessary to ensure the internal information and structure of the website, and must ensure that the domain name transfer IP resolution before the original site can be normal access. Do not have to do transfer IP resolution, and then to migrate data programs, if the process of accident, resulting in your site for a long time can not visit, it is easy to fall right.

(3) Do not have nothing to find smoke, change the IP at will, because even if you do it perfectly, the change of IP or your site is affected, in short, the search engine unfriendly behavior. In fact, search engine in order to crawl efficiency, mainly according to your website cache IP address Crawl page, when your site replaced the IP, the search engine released the old IP cache is a process, will be indexed to your site, resulting in reduced, ranking decline, simply said, often change IP, indicating that the site is unstable, Search engines will be less trusting to your site.
