公司的电脑特别渣渣，IDE开了就卡，I can't stand it ! 就折腾用vim来写脚本。之前看了好多关于设置vim的教程，但是总会出现一点小问题，后来自己去查了才解决。在此特意分享一下，centos下可以直接拿来用。
环境：centos7
首先第一点，更新一下python版本，这个很重要，无论如何，首先更新一下。我这里选择安装python2.7.10，也可以是更高版本。
安装python( --enable-unicode=ucs4很重要 )：
自行下载python2.7.10（ https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz ）
<pre class="prettyprint hljs sql" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">tar -xvf Python-2.7.10.tgz;cd Python-2.7.10;
./configure --prefix=/usr/local/python2.7 --enable-unicode=ucs4;
make && make install;</pre>
安装pip：
<pre class="prettyprint hljs groovy" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">wget https://bootstrap.pypa.io/ez_setup.py;
/usr/local/python2.7/bin/python ez_setup.py;
cd /usr/local/python2.7/bin/;./easy_install pip</pre>
安装vim8.0:
因为系统自带的vim版本太低，所以需要升级
<pre class="prettyprint hljs verilog" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">git clone https://github.com/vim/vim.git && cd vim;
yum install ncurses-devel -y;
./configure --with-features=huge --with-python-config-dir=/usr/local/python2.7/lib/python2.7/config --prefix=/usr/local/vim --enable-pythoninterp=yes --enable-python3interp=yes;
make && make install</pre>
为了不跟老版本的vim冲突，设置vim命令自动关联到新版本的vim：
<pre class="prettyprint hljs ruby" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">echo -e "alias vim='/usr/local/vim/bin/vim'" >>/root/.bashrc</pre>
安装vim插件管理——bundle:
<pre class="prettyprint hljs nginx" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">cd ~;mkdir .vim;cd .vim;mkdir bundle
yum install -y gcc gcc-c++ make
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim</pre>
接下来是配置vim的配置文件，直接复制到~/.vimrc文件内即可，以下是我个人从网上参考的配置文件，可以复制以下命令直接使用：
<pre class="prettyprint hljs vim" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">cat <<ENDTAG >>～/.vimrc

直接打开vim并安装插件（如下图）

等待安装完毕即可：

接下来安装插件YouCompleteMe，这是一个自动补全语句的插件，非常有用：
前提是安装cmake
<pre class="prettyprint hljs nginx" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">wget https://cmake.org/files/v3.12/cmake-3.12.2.tar.gz;
tar -xvf cd cmake-3.12.2.tar.gz;
cd cmake-3.12.2;
ln -s /usr/local/bin/cmake /usr/bin/cmake</pre>
安装YouCompleteMe：
<pre class="prettyprint hljs vim" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">cd ~/.vim/bundle
git clone https://github.com/Valloric/YouCompleteMe.git
cd YouCompleteMe
./install.py --all</pre>
至此，大功告成，我们看下效果：
