linux下安装python

1.下载python3源码包

wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz

2.下载python3编译的依赖包
yum install -y gcc patch libffi-devel python-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

3.解压缩源码包

    tar -zxvf Python-3.6.6.tgz

4.进入源码包文件夹

    cd Python-3.6.6

5.编译且安装

　　 1.进入源码包目录

   - ls查看源码包内容  

   - 释放编译文件 Makefile

./configure –prefix=/opt/python36 # 指定安装目录为/opt/python36

6.编译

1	make # 相当于把源码包里面的代码编译成linux服务器可以识别的代码

7.编译安装,此步才会最终生成 /opt/python36/

  make install
```  

8.更改linux的path变量，添加python3  
vim  /etc/profile

~/.bash_profile # 这个是用户环境变量配置文件 /etc/profile # 系统环境变量配置文件 PATH=/opt/python36/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

1	9.7. 为了永久生效path设置，添加到/etc/profile全局环境变量配置文件中重载配置文件/etc/profile

source /etc/profile ```
