编译安装python3.6的步骤

1.下载python3源码包

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

1.  ls查看源码包内容
2.  释放编译文件 Makefile

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

4.编译

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

5.编译安装,此步才会最终生成 /opt/python36/

make install

注意: 第4步和第5步可以合并执行, 但是中间需要用&&隔开

make && make install  # 先进行make，执行完成之后，才开始执行make install

进入/opt目录查看python36文件夹,我们要的python3都在这里了

/opt/python36/bin/python3
      /opt/python36/bin/pip3
      .....

6.更改linux的path变量，添加python3

修改/etc/profile系统环境变量配置文件，添加以下内容

vim  /etc/profile

![format_png 2][]

~/.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

注意: 一定要将python3的目录放在第一位

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
