关于python2.7的安装在这里
[post cid="103" /]

1、linux下安装python3

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel -y

2、下载 Python3.6代码包

cd /usr/local/src
wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz

安装解压缩命令

yum install xz -y

解压

tar xf Python-3.6.3.tar.xz -C /usr/local/src/
cd /usr/local/src/Python-3.6.3/

启用sqlite支持(如果将来不会用到sqlite的话可以忽略这条)

./configure --enable-loadable-sqlite-extensions --prefix=/usr/local/python36

安装编译所需依赖

yum install gcc-c++ gcc -y

安装

make -j 4 && make install

安装成功后提示

3、做软连接

mv /usr/bin/python /usr/bin/python.bak
ln -s /usr/local/python36/bin/python3.6 /usr/bin/python
mv /usr/bin/pip /usr/bin/pip.bak
ln -s /usr/local/python36/bin/pip3 /usr/bin/pip

4、升级pip

pip install --upgrade pip

5、其他配置
同样需要修改yum和重装supervisor，见这里
