1）Python3 下载地址： wget https://www.python.org/ftp/python/3.6.10/Python-3.6.10.tar.xz 2）环境编译 yum -y install gcc gcc-c++ patch libffi-devel python-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel expat-devel 3）python 安装 解压tar.xz 首先需要进行xz 命令安装yum install -y xz 解压：xz -d Python-3.6.10.tar.xz 再次解压：tar -xf Python-3.6.10.tar mkdir /usr/local/python3.6/ cd Python-3.6.10 ./configure --prefix=/usr/local/python3.6/ --enable-optimizatio --with-openssl=/usr/bin/openssl make -j4 make install 4）建立软件连接生成python3和pip3 ln -s /usr/local/python3.6/bin/python3.6 /usr/bin/python3 ln -s /usr/local/python3.6/bin/pip3.6 /usr/bin/pip3 5）设置 python3 环境变量 export PATH=$PATH:/usr/local/python3.6/bin/ source /etc/profile
