1、安装依赖环境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
2、下载python安装包打开https://www.python.org/downloads/，选择downloads>>All releases然后根据你的需求，下载对应的3.6.X的版本包
3、安装python31、创建目录：mkdir -p /usr/local/python32、解压下载好的Python-3.x.x.tgz包：tar -zxvf Python-3.6.1.tgz(具体包名因你下载的Python具体版本不不同⽽而不不同)3、进入解压后的目录，编译安装： cd Python-3.6.1 ./configure --prefix=/usr/local/python3 make make install 或者 make && make install4、建立python3的软链：ln -s /usr/local/python3/bin/python3 /usr/bin/python35、修改pip的软链接：ln -s /root/python36/bin/pip3 /usr/bin/pip6、并将/usr/local/python3/bin加入PATH：PATH=$PATH:$HOME/bin:/usr/local/python3/binexport PATH7、检查Python3及pip3是否正常可用：python3 -Vpip3 -V
