Be cautious when repeatedly installing/replacing panels in an existing WEB website environment

I met a netizen at noon today who mentioned that he was installing a new WEB environment on the server, which made his original website unusable. So when I asked about the specific implementation process, I found that he originally had a running website, and it was a WordPress program website. It should be that after upgrading to the latest WP5.2 in the past few days, the problem caused the prompt that the PHP version was an old version. So he directly installed the WEB environment in his current WEB server. It is conceivable that this approach will directly cause the existing environment to be replaced or overwritten by directly installing a new WEB installation package on an existing website.

If our current WEB environment cannot meet the current website functions or software version, we cannot upgrade the software immediately. Even if you want to upgrade a single software, you need to make a backup. For example, a netizen also encountered this problem a few days ago. He used a WDCP panel. Snail had had more contact with this panel in his early years and had shared many articles, but he has not been exposed to it since. However, the official upgrade method seems to be incomplete, resulting in an upgrade error and the website cannot be opened.

Even if we are sure to upgrade a certain software version, you still need to back up your data to prevent the unexpected. At the same time, if we do not just upgrade the current version, but install a brand new one-click package that may be different from your existing environment, it will definitely not be installed. After installation, the path and directory of the software will be inconsistent, which will definitely cause Inaccessible. Fortunately, this netizen used Alibaba Cloud server snapshot backup before operation, and then restored the snapshot, so that the website could at least ensure data integrity.

The final solution is to back up the database and website files locally after restoring the data through the mirror. Then reformat the server, install a new WEB environment, and then migrate and restore the data. Randomly reading this kind of article, what I can tell you is, don’t think that the one-click package is very simple. Just throw it in and press Enter to run it. This may cause our server data to malfunction.
