CentOS安装Python3.7

先下载一下压缩包(FTP传也一样)：weget 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

设置一下配置文件，准备编译安装./configure prefix=/usr/local/python3

对于老手，缺啥安装啥，新手建议安装如下安装包（这样你不会出错）

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 kernel-devel libffi-devel

编译安装：make && make install（yum安装没有apt安装方便）

设置软链接：ln -s /usr/local/python3/bin/python3 /usr/bin/python3
