解决vim没有颜色的办法

近期申请了10台测试环境，统一安装完RHEL6.4操作系统以后，发现其中有一台机器使用vim的时候没有颜色高亮，于是就奇怪了，经过一番搜索神技之后终于解决，解决过程与方法如下:

查看vim加载的脚本

1 2	vim :scriptnames

输入如下：

/etc/vimrc                                                                                                                                                                             
/usr/share/vim/vim74/syntax/syntax.vim
/usr/share/vim/vim74/syntax/synload.vim
/usr/share/vim/vim74/syntax/syncolor.vim
/usr/share/vim/vim74/filetype.vim
/usr/share/vim/vim74/ftplugin.vim
/usr/share/vim/vim74/plugin/getscriptPlugin.vim
/usr/share/vim/vim74/plugin/gzip.vim
/usr/share/vim/vim74/plugin/matchparen.vim
/usr/share/vim/vim74/plugin/netrwPlugin.vim
/usr/share/vim/vim74/plugin/rrhelper.vim
/usr/share/vim/vim74/plugin/spellfile.vim
/usr/share/vim/vim74/plugin/tarPlugin.vim
/usr/share/vim/vim74/plugin/tohtml.vim
/usr/share/vim/vim74/plugin/vimballPlugin.vim
/usr/share/vim/vim74/plugin/zipPlugin.vim

经过与其他机器对比后，发现正常。

查看`.vimrc`文件

1	vim ~/.vimrc

set nocompatible        " Vim settings, not Vi settings.  must be first
set autoindent          " Auto align when insert new line, for instance, when using o or O to insert new line.
set ruler               " Show ruler at the bottom-right of vim window
set showcmd
set backspace=indent,eol,start          " Enable delete for backspace under insert mode"
colorscheme darkblue
set number              " Show line number
syntax on
if &term =~ "xterm"
  if has("terminfo")
    set t_Co=8
    set t_Sf=^[[3%p1%dm
    set t_Sb=^[[4%p1%dm
  else
    set t_Co=8
    set t_Sf=^[[3%dm
    set t_Sb=^[[4%dm
  endif
endif
