Question

我有一个小应用程序，我想开始使用supervisord。我尝试了以下

Installed supervisord and controlled a small script
从documentation
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。由于supervisord将负责杀死它，我摆脱了停止部分并且没有守护脚本。

经过反复试验后，我认为这些脚本和配置很有意义，但它们不起作用。

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与＃1相同

我收到一条消息，说找不到命令来源。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

#!/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

Conf

[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与＃1相同

我也试过在这里使用 command = bash -c＆＃34;命令＆＃34; ，即使我觉得在上述所有情况下都不需要。它在文档中提到了here。

我收到以下错误，但我无法找出原因： -

无法生成

流程退出太快

Answer 1

在＃2的情况下，你实际上并不需要激活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 - ＆gt; Supervising virtualenv django app via supervisor

脚本文件

[group:hitler]
programs=gunicorn,celery

[program:gunicorn]
command=bash -c "./hitler.sh gunicorn" 
directory=/home/abhirath/Desktop/Hitler
environment=PATH="/home/abhirath/Desktop/Hitler"
stderr_logfile=/home/abhirath/Desktop/Hitler/Logs/gunicornerr.log
stderr_logfile_backups=1
stdout_logfile=/home/abhirath/Desktop/Hitler/Logs/gunicornout.log
stdout_logfile_backups=1
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true
startretries=0

[program:celery]
command=bash -c "./hitler.sh celery"
directory=/home/abhirath/Desktop/Hitler
environment=PATH="/home/abhirath/Desktop/Hitler"
stderr_logfile=/home/abhirath/Desktop/Hitler/Logs/celeryerr.log
stderr_logfile_backups=1
stdout_logfile=/home/abhirath/Desktop/Hitler/Logs/celeryout.log
stdout_logfile_backups=1
autostart=true
autorestart=true
stopasgroup=true
killasgroup=true
startretries=0

由于我将项目目录指定为环境路径，因此我无需在环境中指定Python解释器的绝对路径。

Supervisord Conf

git rebase master

无法使用Supervisord
