## 安装报错找不到 _ctype zlib 等模块
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 -y install gcc kernel-devel kenel-headers make bzip2

# 解压文件
tar -xvf Python-3.7.1.tar.xz
# 进入到该文件夹
cd Python-3.7.1/
# --prefix 欲安装目录
./configure --prefix=/usr/local/python3.7 --enable-optimizations
# 编译安装,make时间比较长，大概需要15分钟
make
make install
rm -f /usr/bin/python
ln -s /usr/local/python3.7/bin/python3.7 /usr/bin/python
ln -s /usr/local/python3.7/bin/pip3 /usr/bin/pip3
# 还需要重新编译安装才有效
如果先make再yum，可能还找不到，需要再次configure
