无法使用 Supervisord 启动 Python 应用程序

Question

我有一个小应用程序，我想开始使用 supervisord。我已经尝试了以下

• Installed supervisord and controlled a small script
• 阅读documentation 中的简介、运行 Supervisord 和配置文件部分
• Setting up groups in supervisord

我的初始 shell 脚本可以通过将 PID 保存在文本文件中来启动和停止 celery 和 Flask 作为守护进程。因为 supervisord 会负责杀死它，所以我去掉了 stop 部分并且不对脚本进行守护。

经过反复试验，这些是我认为有意义但不起作用的脚本和配置二重奏。

Shell 脚本

#!/bin/bash


if [[ $1 == "gunicorn" ]]
then
    cd /home/abhirath/Desktop/Hitler
    source env/bin/activate
    python env/bin/gunicorn -b 0.0.0.0:3333 -w 3 gunicornserve:app

elif [[ $1 == "celery" ]]
then
    cd /home/abhirath/Desktop/Hitler
    source env/bin/activate
    python env/bin/celery -A testrunner worker --concurrency=3 --loglevel=info

else
    echo "Usage:-"
    echo "To start celery:-"
    echo "./hitler.sh celery"
    echo "To start Gunicorn"
    echo "./hitler.sh gunicorn"
fi

配置文件

[group:hitler]
programs=gunicorn,celery

[program:gunicorn]
command=/home/abhirath/Desktop/Hitler/hitler.sh gunicorn
stderr_logfile =/home/abhirath/Desktop/supervisor.err.log
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true

[program:celery]
command=/home/abhirath/Desktop/Hitler/hitler.sh celery
stderr_logfile=/home/abhirath/Desktop/supervisor.err2.log
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true

没有shell文件

[group:hitler]
programs=gunicorn,celery

[program:gunicorn]
command=source env/bin/activate; python env/bin/gunicorn -b 0.0.0.0:3333 -w 2 gunicornserve:app;
directory=/home/abhirath/Desktop/Hitler

[program:celery]
command=source env/bin/activate; python env/bin/celery -A testrunner worker --concurrency=4 --loglevel=info;
directory=/home/abhirath/Desktop/Hitler

stderr_logfile、autostart、autorestart、stopasgroup、killasgroup 同 #1

我收到一条消息说找不到命令 source。我在同一目录中的终端上尝试了相同的命令，它可以工作。

Shell 脚本

    if [[ $1 == "gunicorn" ]]
    then
        source env/bin/activate
        python env/bin/gunicorn -b 0.0.0.0:3333 -w 3 gunicornserve:app
    
    elif [[ $1 == "celery" ]]
    then
        source env/bin/activate
        python env/bin/celery -A testrunner worker --concurrency=3 --loglevel=info
    
    else
        echo "Usage:-"
        echo "To start celery:-"
        echo "./hitler.sh celery"
        echo "To start Gunicorn"
        echo "./hitler.sh gunicorn"
    fi

会议

[group:hitler]
programs=gunicorn,celery

[program:gunicorn]
command=./hitler.sh gunicorn
directory=/home/abhirath/Desktop/Hitler    

[program:celery]
command=./hitler.sh celery
directory=/home/abhirath/Desktop/Hitler

stderr_logfile、autostart、autorestart、stopasgroup、killasgroup 同 #1

我也尝试过使用 command=bash -c "command here"，尽管我觉得在上述所有情况下都不需要它。文档中提到了here。

我收到以下错误，但我无法弄清楚原因：-

无法生成

进程退出太快

在 #2 的情况下，您实际上不需要激活 virtualenv。您可以将其更改为：

[group:hitler]
programs=gunicorn,celery

[program:gunicorn]
command=/absolute/path/to/env/bin/gunicorn /absolute/path/to/gunicornserve:app -b 0.0.0.0:3333 -w 2
directory=/home/abhirath/Desktop/Hitler

[program:celery]
command=/absolute/path/to/env/bin/celery -A testrunner worker --concurrency=4 --loglevel=info
directory=/home/abhirath/Desktop/Hitler

@MohammadAmin 和 @ymonad 给出了我在这个答案中使用的精彩建议。由于这里给出的解释，我找到了一个更简单的解决方案 -> Supervising virtualenv django app via supervisor

脚本文件

#!/bin/bash


if [[ $1 == "gunicorn" ]]
then
  env/bin/python env/bin/gunicorn -b 0.0.0.0:3333 -w 3 gunicornserve:app 

elif [[ $1 == "celery" ]]
then
  export C_FORCE_ROOT='true'
  env/bin/python env/bin/celery -A testrunner worker --concurrency=3 --loglevel=info

else
  echo "Usage:-"
  echo "To start celery:-"
  echo "./hitler.sh celery"
  echo "To start Gunicorn"
  echo "./hitler.sh gunicorn"

fi

由于我将项目目录指定为环境路径，因此无需指定环境中Python解释器的绝对路径。
