安装python3的依赖
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make
添加epel扩展源
yum -y install epel-release
安装pip
yum -y install python-pip
pip install wget
提示更新pip
pip install --upgrade pip
下载python包
tar -zxvf Python-3.7.4.tgz
./configure prefix=/usr/local/python3
make && make install
3.7以上版本有编译错误，需要安装一个依赖
yum install libffi-devel -y
make install
whereis python3
