1，编辑文件/usr/share/vim/vimrc
sudo vi /usr/share/vim/vimrc
2，在set backspace=2下面一行插入如下代码
set ai " auto indenting set ruler " show the cursor position set hlsearch " highlight the last searched term set history=1000 " keep 1000 lines of history syntax on " syntax highlighting filetype plugin on " use the file type plugins
3，保存退出，查看效果
