install

目前CentOS 7的 yum repo中只有Python 3.6.8, 项目中要使用3.7.5, 只能从源码安装

1) 安装依赖组件

# yum install gcc openssl-devel bzip2-devel libffi-devel

2) 下载Python 3.7.5源码包, 解压
From https://www.python.org/downloads/release/python-375/

# cd /usr/src
# curl https://www.python.org/ftp/python/3.7.5/Python-3.7.5.tgz -O
# tar zxvf Python-3.7.5.tgz

3) 配置安装

# cd /usr/src/Python-3.7.5
# ./configure --enable-optimizations
# make altinstall

4) 创建python软链接

安装后的Python 3.7 执行文件位于: /usr/local/bin/python3.7

# ln -s /usr/local/bin/python3.7 /usr/bin/python3
# ln -s /usr/bin/python3 /usr/bin/python

# python -V
Python 3.7.5

5) 清理

# rm -f /usr/src/Python-3.7.5.tgz

1）安装IUS软件源

#安装EPEL依赖
sudo yum install epel-release

#安装IUS软件源
sudo yum install https://centos7.iuscommunity.org/ius-release.rpm

2）安装Python3.6

sudo yum install python36u

#创建符号链接(可选)
sudo ln -s /bin/python3.6 /bin/python3

3）安装pip3(可选)

sudo yum install python36u-pip

#创建一个到pip3的符号链接(可选)
sudo ln -s /bin/pip3.6 /bin/pip3
