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

cd /usr/local
$ wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz
$ tar -xvJf  Python-3.7.0.tar.xz

3.编译安装

mkdir /usr/local/python3 #创建编译安装目录
cd Python-3.7.0
./configure --prefix=/usr/local/python3
make && make install

4.创建软连接（这样创建的好处在于不用修改yum）

ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3

5.验证是否成功（注意V大写）

python3 -V
pip3 -V
