Why Install Old Version Packages

Baota Panel is a management panel that makes server administration easy through a web interface, significantly improving operational efficiency. It not only simplifies the installation of essential programs for websites but also allows you to create and manage websites, FTP, and databases. It features a visual file manager, graphical CPU, memory, and traffic monitoring, and scheduled tasks. Therefore, using Baota Panel for website setup is very convenient. However, only running a small website on a server can feel a bit wasteful; using the server for web scraping or other programming tasks is highly beneficial.

Baota Panel doesn’t come with Python 3 by default, and since Python 2 is no longer maintained, upgrading to Python 3 and setting it as the default is the first step. I couldn’t find direct tutorials online, so after successfully setting up the environment through trial and error, I’m sharing the detailed process to help others avoid similar frustrations.

First, a brief overview of the process. Upon inspecting the Baota script vi /usr/bin/bt, you’ll find:

`py26=$(python -V 2>&1|grep '2.6.')
if [ "$py26" != "" ];then
pythonV=python3
fi`

Python 3 can run the Baota Panel, meaning it’s compatible. However, Baota Panel’s installation requires Python 2, so the process involves these steps:

First, run the Baota Panel installation script to install the panel.
Install Python 3 and set it as the default.
Modify yum to use Python 2.

Running the Baota Script to Install the Panel

For a clean CentOS system, directly run the official installation script. My system is CentOS 7, so I’m using the latest Linux Panel 6.0:

bash
yum install -y wget && wget -O install.sh [https://download.bt.cn/install/install_6.0.sh](https://download.bt.cn/install/install_6.0.sh) && bash install.sh

linux_pc

Once installed, you’ll see a prompt. The default port is 8888; paste it into your browser to access the panel.

Installing Python 3

python The powerful Scrapy web crawling framework is compatible with Python 3.6, but higher versions might cause errors during installation. Therefore, I’ll use Python 3.6.7 for this installation:

wget [https://www.python.org/ftp/python/3.6.7/Python-3.6.7.tgz](https://www.python.org/ftp/python/3.6.7/Python-3.6.7.tgz)
tar zxvf Python-3.6.7.tgz
cd Python-3.6.7
./configure
make && make install

Python 3 is now installed.

Setting Python 3 as the Default Python

rm -f /usr/bin/python
ln -s /usr/local/bin/python3 /usr/bin/python
rm /usr/bin/pip
ln -s /usr/local/bin/pip /usr/local/bin/pip

Modifying Yum to Use Python 2

vi /usr/bin/yum

Change /usr/bin/python to /usr/bin/python2.

After making these changes, run yum update -y && python --version && pip --version. If yum runs without errors, and your Python and pip versions are for Python 3, your environment is successfully set up. You can now easily set up your Scrapy web crawling environment.

Alternatively, Install Python 3 Directly with Conda

Download and Install Conda

wget [https://repo.anaconda.com/archive/Anaconda3-2019.07-Linux-x86_64.sh](https://repo.anaconda.com/archive/Anaconda3-2019.07-Linux-x86_64.sh)
bash Anaconda3-2019.07-Linux-x86_64.sh

Follow the prompts, confirming each step, and Conda will be installed.

Add Conda to PATH

# >>> conda init >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$(CONDA_REPORT_ERRORS=false '/root/anaconda3/bin/conda' shell.bash hook 2> /dev/null)"
if [ $? -eq 0 ]; then
    \eval "$__conda_setup"
else
    if [ -f "/root/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/root/anaconda3/etc/profile.d/conda.sh"
        CONDA_CHANGEPS1=false conda activate base
    else
        \export PATH="/root/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda init <<<

Summary

Above are two methods for installing a Python 3 environment on a server with Baota Panel. I recommend using the second method with Conda for its convenience. I hope this helps!
