Linux-Python3的安装

#先安装依赖包，避免后面出现问题
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 mysql-devel

#安装gcc编辑包
yum install gcc gcc-c++ kernel-devel 

#wget 下载Python3.6的tgz的包
wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz

#解压
tar -xvf Python-3.6.8

#切换到目录
cd Python-3.6.8

#指定安装目录
./configgure --prefix=/路径/python36

#编译（时间会比较慢）
make

#安装
make install

#安装完直接输入python3是无法使用的，pip3也是，需要配置软连接
ln -s /路径/python36/bin/python36 /user/bin/python3
ln -s /路径/python36/bin/pip3 /user/bin/pip3
