在CentOS上安装Python的步骤如下：

yum -y install gcc zlib zlib-devel libffi libffi-devel readline-devel openssl-devel openssl11 openssl11-devel

wget https://www.python.org/ftp/python/3.11.0/Python-3.11.0.tgz
tar -xzf Python-3.11.0.tgz
cd /root/Python-3.11.0

export CFLAGS=$(pkg-config --cflags openssl11)
export LDFLAGS=$(pkg-config --libs openssl11)

./configure --prefix=/usr/python --with-ssl
make -j (nproc)
sudo make altinstall

sudo ln -sf /usr/local/bin/python3.11 /usr/bin/python3
sudo ln -sf /usr/local/bin/pip3.11 /usr/bin/pip3

python3 --version
pip3 --version

python2 --version
python3 --version

wget https://www.python.org/ftp/python3/3.9.0/Python-3.9.0.tgz

tar -zxvf Python-3.9.0.tgz
cd Python-3.9.0

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make

mkdir -p /usr/local/python3

./configure --prefix=/usr/local/python3
make && make install

ln -s /usr/local/python3/bin/python3.9 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.9 /usr/bin/pip3

vi ~/.bash_profile
export PYTHON_HOME=/usr/local/python3
export PATH=$PYTHON_HOME/bin:$PATH
source ~/.bash_profile

echo $PYTHON_HOME
python3 --version

yum install epel-release

如果在编译过程中遇到Could not build the ssl module! Python requires a OpenSSL 1.1.1 or newer错误，需要确保已安装OpenSSL 1.1.1或更高版本，并正确配置编译环境。

以上教程可以帮助您在CentOS系统上成功安装Python。请根据您的需求和系统版本选择合适的教程进行操作。
