阿里云 CentOS7.4 安装 Python3.6的方法讲解
<p>1、到python官网 https://www.python.org 查找最新的原码，我使用的，Python-3.6.3</p>
<p>
2、mkdir /home/soft</p>
<p>
创建软件管理目录、</p>
<p>
3、cd /home/soft/</p>
<p>
进入soft目录，因为我下一步是下载python的源码</p>
<p>
4、wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz</p>
<p>
下载Python-3.6.3的源码到/home/soft/里，如果没有安装wget 请执行下面的命令，</p>

<strong>安装wget</strong></p>
<p>
5、tar -xzvf Python-3.6.3.tgz -C /Python-3.6</p>
<p>
解压到 /home/soft/Python-3.6</p>
<p>

7、./configure --prefix=/usr/local/</p>
<p>
我们打算把python3.6安装到目录 /usr/local/</p>
<p>
源码的安装一般由3个步骤组成：配置（configure）、编译（make）、安装（make install）</p>
<p>
8、make</p>
<p>
9、make install</p>
<p>
ython3.6程序的执行文件：/usr/local/bin/python3.6</p>
<p>
python3.6应用程序目录：/usr/local/lib/python3.6</p>
