Python升级
<h3>1、下载安装包</h3>
<pre><code>cd /usr/local/src
wget https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tgz
tar -zxvf Python-2.7.14.tgz</code></pre>
<h3>2、编译</h3>
<pre><code>cd Python-2.7.14
./configure --prefix=/usr/local/python27
make && make install</code></pre>
<h3>3、置换老版本</h3>
<pre><code>mv /usr/bin/python /usr/bin/python_old
ln -s /usr/local/python27/bin/python2.7 /usr/bin/python
/usr/bin/python</code></pre>
<h3>4.修改yum依靠的python源，避免yum不能用</h3>
<pre><code>vi /usr/bin/yum</code></pre>
<p>将第一行 #!/usr/bin/python 改为#!/usr/bin/python2.6 或者 #!/usr/bin/python_old</p>
