备注
以下操作都在root用户下执行
如果不是root用户请在命令前加 sudo
1.安装编译相关工具
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 libffi-devel -y
2.下载安装包解压
# 创建下载的文件路径（自己找位置即可）
mkdir /usr/download
# 切换到刚新建的文件夹，
cd /usr/download
# 下载
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz
# 解压
tar -xvJf Python-3.7.0.tar.xz
3.编译安装
# 创建编译安装目录
mkdir /usr/local/python3
# 刚刚解压的目录
cd Python-3.7.0
./configure --prefix=/usr/local/python3
make && make install
4、创建软连接，
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
# 修改pip3的指向
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3
5、验证
python3 -V
pip3 -V
