No color display solution for the vi Editor

In linux, you can use vi to edit and modify the file configuration without the color display file content. In particular, some keywords cannot be displayed in color, causing great inconvenience during the configuration service process. Here is a solution.

Third: Modify # vi/etc/vimrc and add "syntax on" to the following statement. Then restart vi to enable highlighting.
