Flask项目部署的一些配置

离线安装python3.9.8与相关依赖

  • 解压源码包到指定目录

    1
    tar -xzvf /target_path/Python-3.9.8.tar.gz -C /target_path/

  • 进入解压目录并配置

    1
    2
    cd /target_path/Python-3.9.8
    ./configure --prefix=/target_path/python3

  • 在python解压目录中执行编译并安装

    1
    2
    make
    sudo make install

  • 更改python3文件所有者与所属群组

    1
    2
    cd ~
    sudo chown -R user:user /target_path/python3

  • 安装项目依赖模块

    • 解压对应架构依赖压缩包到指定目录

      1
      unzip -d /unzip_path/whl python3-xxx.zip

    • 创建项目隔离环境

      1
      2
      cd /target_path/python3 && mkdir venvs
      /target_path/python3/bin/python3 -m venv /target_path/python3/venvs/flask

    • 安装依赖模块 

      1
      2
      cd ~
      /target_path/python3/venvs/flask/bin/pip3 install --no-index --find-links=/unzip_path/whl -r /unzip_path/whl/requirements.txt

项目代码解压与uwsgi配置

  • 解压项目代码到指定目录并进入目录

    1
    2
    unzip -d /target_path/ python_code.zip
    cd /target_path/flask

  • 编辑 uwsgi-name.ini

    1
    vim uwsgi-name.ini

    编辑内容如下：

    [uwsgi]
    http = 0.0.0.0:xxxx
    chdir = /target_path/flask
    wsgi-file = manage.py
    processes = 4
    threads = 2
    post-buffering = 8192
    buffer-size = 65535
    socket-timeout = 10
    uid = user
    master = true
    protocol = uwsgi
    pidfile = /target_path/flask/uwsgi.pid
    py-autoreload = 1
    callable = app

supervisor配置与启动

  • 安装supervisor

    1
    /target_path/python3/bin/pip3 install --no-index /unzip_path/whl/supervisor-4.2.5-py2.py3-none-any.whl

  • 创建supervisor目录并初始化supervisor配置

    1
    2
    3
    mkdir /target_path/supervisor
    cd /target_path/supervisor && mkdir conf.d
    cd ~ && /target_path/python3/bin/echo_supervisord_conf > /target_path/supervisor/supervisord.conf

  • 更改supervisor配置

    1
    vim /target_path/supervisor/supervisord.conf

    跳转到文件最后并修改最后两行为：

    1
    2
    [include]
    files = /target_path/supervisor/conf.d/*.ini

  • 创建项目配置文件并启动

    1
    2
    cd /target_path/supervisor/conf.d
    vim flask.ini
