最权威的原始步骤可以参考github中关于此插件的README.md,如果时间允许的话,尽量多看几遍可以避免很多不必要的麻烦。

一.版本检测
使用vim --version指令,检 vim版本是否大于7.3.584,一般新系统都满足。打开vim,输入下述指令查看是否支持python。如果显示为1,则表示支持python;如果显示为0,则表示不支持python,需要重新下载编译vim,使其支持python。

:echo has('python')
二.下载Vundle和YouCompleteMe插件
输入以下指令,下载Vundle

git clone https://github.com/gmarik/Vundle.vim.git ~/.vim/bundle/Vundle.vim
下载成功后,在用户根目录下面,修改.vimrc文件,追加下面语句以便后续安装YouCompleteMe插件

set nocompatible 
filetype off 
set rtp+=~/.vim/bundle/Vundle.vim 
call vundle#begin() 
Plugin 'gmarik/Vundle.vim' 
Plugin 'Valloric/YouCompleteMe' 
call vundle#end() 
filetype plugin indent on 
然后在vim中先按Esc建,并且输入以下指令安装插件:

:PluginInstall
三.编译YouCompleteMe
在编译之前下载编译工具,准备编译YouCompleteMe

sudo yum install automake gcc gcc-c++ kernel-devel cmake
sudo yum install python-devel python3-devel
编译YouCompleteMe使其支持C/C++ 自动补全

cd ~/.vim/bundle/YouCompleteMe
./install.py --clang-completer

四.配置vim
修改.vimrc文件

let g:ycm_global_ycm_extra_conf = '/home/li/.vim/bundle/YouCompleteMe/.ycm_extra_conf.py 
let g:ycm_seed_identifiers_with_syntax=1    " 语法关键字补全 
let g:ycm_confirm_extra_conf=0  " 打开vim时不再询问是否加载ycm_extra_conf.py配置 
inoremap <expr> <CR>  pumvisible() ? "\<C-y>" : "\<CR>"    "回车即选中当前项 
set completeopt=longest,menu    "让Vim的补全菜单行为与一般IDE一致(参考VimTip1228)

.ycm_extra_conf.py文件内容

    for extension in SOURCE_EXTENSIONS:
      replacement_file = basename + extension
      if os.path.exists( replacement_file ):
        compilation_info = database.GetCompilationInfoForFile(
          replacement_file )
        if compilation_info.compiler_flags_:
          return compilation_info
    return None
  return database.GetCompilationInfoForFile( filename )

def FlagsForFile( filename, **kwargs ):
  if database:

    compilation_info = GetCompilationInfoForFile( filename )
    if not compilation_info:
      return None

    final_flags = MakeRelativePathsInFlagsAbsolute(
      compilation_info.compiler_flags_,
      compilation_info.compiler_working_dir_ )

  else:
    relative_to = DirectoryOfThisScript()
    final_flags = MakeRelativePathsInFlagsAbsolute( flags, relative_to )

  return {
    'flags': final_flags,
    'do_cache': True
  }
