1.注释：必须是vim命令 而不是vi命令
1.安装依赖的工具
$ sudo yum install git
$ sudo yum install wget
$ sudo yum install gcc
$ sudo yum install gcc-++
$ sudo yum install gcc-gfortran
$ sudo yum install make
$ sudo yum install gdb
$ sudo yum install cmake
$ sudo yum install clang
$ sudo yum install clang-analyzer
$ sudo yum install vim
2.安装python 及python 所需要的的依赖库
$sudo yum install python
$sudo yum install python-devel
3.手动安装cmak 编辑器
3.1在cmake 官网下载 （https://cmake.org/download/）官网地址下载3.5 以上的版本
3.2 解压 、编译、安装
./configure --prefix=/YouPathToInstall/Cmake
make
make install
4.安装clang
首先，从http://llvm.org/releases/download.html#3.3这边下载最新的版本。如果从SVN下载代码的话，已经是3.4的开发版本了，如果需要使用稳定版本，推荐自己下载3.3的代码包，需要下载5个文件：
LLVM source code
Clang source code
Clang Tools Extra source code
Compiler RT source code
LibC++ source code
下载好了以后，四个压缩包都解压出来，得到四个目录：
llvm-3.3.src
cfe-3.3.src
clang-tools-extra-3.3.src
compiler-rt-3.3.src
libcxx-3.3.src
然后按下面的步骤组织：
mv cfe-3.3.src clang
mv clang/ llvm-3.3.src/tools/
mv clang-tools-extra-3.3.src extra
mv extra/ llvm-3.3.src/tools/clang/
mv compiler-rt-3.3.src compiler-rt
mv compiler-rt llvm-3.3.src/projects/
这样以后clang，clang-tools-extra和compiler-rt就可以和llvm一起编译了。
在llvm-3.3.src同一层目录上新建个目录build-3.3并进入：
mkdir build-3.3
cd build-3.3
然后configure：
../llvm-3.3.src/configure --enable-optimized --enable-targets=host-only
注意：这边两个选项推荐大家加上，否则会产生巨大的文件，我第一次编译的时候，没有加上这两个选项，编译出来的结果多大9.4G（够吓人的吧？把我的磁盘都耗尽了，还报错，google了好久才发现是磁盘空间不够），耗时超过一个半小时，加上以后编译出来的结果不到1G，i5四核20分钟多一点就编译完成。
然后make：
make -j4
然后make install：
sudo make install
用clang++ -v查看下：
clang version 3.3 (tags/RELEASE_33/final) Target: x86_64-unknown-linux-gnu Thread model: posix |
5.下载安装vim
git clone https://github.com/vim/vim.git
cd vim
git pull
cd src
./configure --enable-pythoninterp=yes --enable-python3interp=yes（支持python）
make distclean # if you build Vim before
修改Makefile
如下图所示打开448 和 450 行的注释行
make
sudo make install
执行
$vi --version | grep python
如下图所示：
6. 配置 Vundle:
6.1.下载 $ git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
6.2 编辑 vim .vimrc
set nocompatible " be iMproved, required
filetype off " required
" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')
" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
" The following are examples of different formats supported.
" Keep Plugin commands between vundle#begin/end.
" plugin on GitHub repo
Plugin 'tpope/vim-fugitive'
" plugin from http://vim-scripts.org/vim/scripts.html
Plugin 'L9'
" Git plugin not hosted on GitHub
Plugin 'git://git.wincent.com/command-t.git'
" git repos on your local machine (i.e. when working on your own plugin)
"Plugin 'file:///home/gmarik/path/to/plugin'
" The sparkup vim script is in a subdirectory of this repo called vim.
" Pass the path to set the runtimepath properly.
Plugin 'rstacruz/sparkup', {'rtp': 'vim/'}
" Install L9 and avoid a Naming conflict if you've already installed a
" different version somewhere else.
"Plugin 'ascenator/L9', {'name': 'newL9'}
" All of your Plugins must be added before the following line
call vundle#end() " required
filetype plugin indent on " required
" To ignore plugin indent changes, instead use:
"filetype plugin on
"
" Brief help
" :PluginList - lists configured plugins
" :PluginInstall - installs plugins; append `!` to update or just :PluginUpdate
" :PluginSearch foo - searches for foo; append `!` to refresh local cache
" :PluginClean - confirms removal of unused plugins; append `!` to auto-approve removal
"
" see :h vundle for more details or wiki for FAQ
" Put your non-Plugin stuff after this line
6.3 保存并退出
6.4 install Install Plugins
vim .vimrc
执行命令:PluginInstall
或者在终端执行
6.5 下载YouCompleteMe源码
git clone https://github.com/Valloric/YouCompleteMe.git ~/.vim/bundle/YouCompleteMe
cd ~/.vim/bundle/YouCompleteMe
#获取YCM的依赖包
git submodule update --init --recursive
#然后在在vimrc文件中加入
Bundle 'Valloric/YouCompleteMe'
./install.py --clang-completer
执行完上述步骤就就已经安装完成自动补齐软件YouCompleteMe
