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。我试过以下方法

• Installed supervisord and controlled a small script
• 阅读介绍，从documentation运行管理程序和配置文件部分
• Setting up groups in supervisord

我最初的shell脚本可以通过将PID保存在文本文件中来启动和停止celeri和Flask作为守护进程。由于supervisord会负责销毁它，所以我去掉了stop部分，并将脚本非守护程序化。在

经过反复试验，这些是脚本和conf duos，我认为有道理，但他们不起作用。在

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

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_日志文件，autostart，autorestart，stopasgroup，killasgroup与#1相同

我收到一条消息说找不到命令源。我在同一个目录下的终端上尝试了相同的命令，它起作用了。在

三

Shell脚本

#!/bin/bash


    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

形态

[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_日志文件，autostart，autorestart，stopasgroup，killasgroup与#1相同

我还尝试使用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。在

我得到了以下错误，我不知道为什么：在

Could not spawn

Process Exited too quickly

Answer 1

在#2的情况下，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给出了很好的建议，我在回答中使用了这些建议。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

因为我将项目目录指定为环境路径，所以不需要指定环境中Python解释器的绝对路径。在
