vim是从 vi 发展出来的一个文本编辑器。功能丰富，在程序员中被广泛使用，而且可以根据自己需要对其进行配置，下面我们来介绍一些vim的基本配置。
首先将你的Linux切换到超级用户，输入命令 su，输入密码再回车切换到root用户，cd进入当前用户主工作目录，输入vim .vimrc进行vim配置.
经试验以上方法配置的vim只对root用户有效，正确的做法是直接将目录切换至用户根目录~，然后创建vim配置文件 vim ~/.vimrc，然后 :wq 保存退出。
[xiong@localhost ~]$ vim ~/.vimrc
以下是我的配置文件，值得说明的一点是最后一个设置set filetype=c是设置默认语言为C语言，在没加这个设置之前我使用vim修改文件发现vim的的设置并没有启用，看了一些解决方案后发现原来是没加程序后缀名，vim无法识别是什么类型文件，当做普通文档格式处理，加上这个设置后即使文件后无.c也自动当成C语言文件格式处理。
还有一个功能自动补齐括号本来设置了在输入程序时发现不合适的地方又删掉了，自动补齐括号的代码为:
inoremap ( ()i
inoremap [ []i
inoremap { {}i
inoremap < <>i
至于删掉的原因请先看看我用来测试的代码。
如图所示，在代码中我使用了一个for循环，如果加了自动补齐括号功能，当我输入<号时，会出现如下情况:
;i<>;i++)
由于是自动补齐，可能在需要输入<,>等符号时它会自动帮你补齐错误的代码，所以为了避免这种错误我建议大家如果要设置自动补齐功能别贪图省事把<,>的自动补齐一起设置上，毕竟<,>还是用得很多的。
