1.安装相应的编译工具
在root用户下(不要用普通用户,麻烦),全部复制粘贴过去,一次性安装即可.
yum -y groupinstall "Development tools"
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
yum install -y libffi-devel zlib1g-dev
yum install zlib* -y
2.下载安装包
wget wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz
3.解压
tar -xvJf Python-3.7.2.tar.xz
4.创建编译安装目录
mkdir /usr/local/python3
5.安装
cd Python-3.7.2
./configure --prefix=/usr/local/python3 --enable-optimizations --with-ssl
make && make install
what-does-enable-optimizations-do-while-compiling-python
6.创建软链接
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3
7.验证是否成功
python3 -V
pip3 -V
