在CentOS上安装Python常用方法如下：
sudo yum update -y。sudo yum install python3 -y。若需特定版本，如Python 3.9，可添加对应仓库后安装（以IUS仓库为例）：sudo yum install -y https://centos7.iuscommunity.org/ius-release.rpm，再sudo yum install -y python39u python39u-devel。sudo yum groupinstall "Development Tools" -y，sudo yum install openssl-devel bzip2-devel libffi-devel zlib-devel readline-devel sqlite-devel wget -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 -j $(nproc)，sudo make altinstall。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，并添加相关配置到.bashrc文件。pyenv install 3.x.y，pyenv global 3.x.y。安装后可通过python3 --version验证。
