CentOS安装Python常用方法如下：
sudo yum update -y。sudo yum install python3 -y。python3 --version。sudo yum groupinstall "Development Tools" -y，sudo yum install openssl-devel bzip2-devel libffi-devel -y。wget https://www.python.org/ftp/python/3.x.y/Python-3.x.y.tgz（x.y为版本号）。tar xzf Python-3.x.y.tgz，cd Python-3.x.y，./configure --enable-optimizations，make altinstall。python3.x --version。sudo yum install gcc zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel tk-devel libffi-devel xz-devel -y。curl https://pyenv.run | bash，并配置环境变量（编辑~/.bashrc添加相关内容，然后source ~/.bashrc）。pyenv install 3.x.y，pyenv global 3.x.y。python --version。
