步骤详情

1、CentOS安装Python的依赖包

yum groupinstall "Development tools" yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel . .

2、下载Python3X的源码包并编译

wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz tar -zxvf Python-3.6.1.tgz cd Python-3.6.1 ./configure --prefix=/usr/local/python36 yum -y install zlib* openssl-devel make && make install . .

3、把#! /usr/bin/python修改为#! /usr/bin/python2

sed -i 's/#!/usr/bin/python/#!/usr/bin/python2.6/' /usr/bin/yum （可选）sed -i 's/#! /usr/bin/python/#! /usr/bin/python2/' /usr/libexec/urlgrabber-ext-down . .

4、把/usr/bin/下的python2替换成python3

mv /usr/bin/python /usr/bin/pythonold cp /usr/local/python36/bin/python3.6 /usr/bin/python cp /usr/local/python36/bin/pip3 /usr/bin/pip3 . .

写成shell脚本执行

#1、CentOS安装Python的依赖包
yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

#2、下载Python3X的源码包并编译
wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz
tar -zxvf Python-3.6.1.tgz 
cd Python-3.6.1
./configure --prefix=/usr/local/python36
yum -y install zlib* openssl-devel
make && make install

#3、把#! /usr/bin/python修改为#! /usr/bin/python2
sed -i 's/#!\/usr\/bin\/python/#!\/usr\/bin\/python2.6/' /usr/bin/yum
#（可选）sed  -i    's/\#\! \/usr\/bin\/python/\#\! \/usr\/bin\/python2/'   /usr/libexec/urlgrabber-ext-down

#4、把/usr/bin/下的python2替换成python3
mv /usr/bin/python /usr/bin/pythonold
cp /usr/local/python36/bin/python3.6 /usr/bin/python
cp /usr/local/python36/bin/pip3 /usr/bin/pip3
