supervisor 启动python脚本失败

Question

问题：supervisor 启动 python 脚本失败

supervisor配置如下

[supervisord]
nodaemon=false
[program:app]
command=python /path/to/app/report.py
autostart=true
autorestart=true
startsecs=3
stdout_logfile=/path/to/app/info.log
stderr_logfile=/path/to/app/err.log

report.py 内容（功能每分钟请求一次指定接口）

使用 python report.py 执行没有问题

import requests
import random
import time

def do_something():
    while True:
        params = (
            ('foo', 'foo'),
            ('bar', 'bar'),
        )

        r = requests.get('http://url/report.php', params=params)
        print(r.url)
        print(r.text)
        time.sleep(60)

if __name__ == "__main__":
    do_something()

报错信息

Answer 1

目前该问题已经解决，原因是题主在修改 supervisor 配置后，没有 reload 配置。

Answer 2

检查一下supervisor安装时用的python版本是否和python命令版本一致
