Thoroughly solve the problem of dedecms message board installation-PHP development

The website that previously used dedecms5.5 has been running on the server for two years. One day, I suddenly wanted to add a message board module to the website. So I found the module-message book module in the background and installed it, the installation fails due to issues such as insufficient write permissions and file loss. So I went to the Internet to search for a solution, but I couldn't find it. That's terrible. But I didn't want to give up, so I continued to explore... The final problem is solved. Now post the method: the website that previously used dedecms5.5 has been running on the server for two years. One day I suddenly wanted to add a message board module to the website, so I found the module-message book module in the background, after installation, the installation fails due to issues such as insufficient write permissions and file loss. So I went to the Internet to search for a solution, but I couldn't find it. That's terrible. But I didn't want to give up, so I continued to explore... The final problem is solved. Now post the method:

1. Download the corresponding dededecms version, install and install the message board locally (generally there is no problem), find the following files and upload them to the corresponding directory on the server.
