1. Location of configuration files
Under directory/etc/, there is a file named VIMRC, which is a public vim configuration file in the system and is valid for all users. In each user's home directory, you can create a private configuration file, named: ". VIMRC ". For example, under the/root directory, there is usually already one. VIMRC file.
If you do not know the location of the configuration file and script, you can use the command in VIM: Scriptnames, the following path will be displayed
/etcimrc
/usrimim72/syntax/syntax.vim
/usrimim72/syntax/synload.vim
/usrimim72/syntax/syncolor.vim
/usrimim72/filetype.vim
/usrimim72/ftplugin.vim
/home/kdj/.vimrc
...
If you do not know the search location for the Vim configuration file, enter: version, which will be displayed

1) Open VIMRC and add the following statement to make syntax highlighting:
