Supervisor；supervisor.conf；logfile_maxbytes=50MB；loglevel=debug；debug；warn；trace)；pidfile=/tmp/supervisord.pid；autostart=true：user=mongodb：

我有一个正在运行的Ubuntu Docker容器，它安装了python3.7、mongodb和supervisor。当我试图通过supervisor服务运行我的python脚本时，它抛出了以下错误：

supervisor: couldn't exec /data/code/venvs/cleverInvest/bin/python: ENOEXEC
supervisor: child process was not spawned

supervisor.conf

[supervisord]

我已经尝试在python文件中添加一个!#/bin/sh，或者给他们一个777规则。似乎没有任何帮助。

这里是我的Dockerfile

所以我自己想出来了，我想写出我的解决方案，以防其他人也有同样的问题。

我只是改变了启动python脚本的方法，使用全局安装的python版本，而不是通过virtualenv。所以我的supervisor.conf文件现在看起来像这样：

[supervisord]
;logfile=/var/app/logs/ ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB        ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=5           ; (num of main logfile rotation backups;default 10)
loglevel=debug                ; (log level;default info; others: debug,warn,trace)
pidfile=/tmp/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
nodaemon=true                ; (start in foreground if true;default false)
minfds=1024                  ; (min. avail startup file descriptors;default 1024)
minprocs=200                 ; (min. avail process descriptors;default 200)

[program:mongod]
;command=/usr/bin/mongod --config /etc/mongod.conf
command=/usr/bin/mongod
stdout_logfile=/var/log/supervisor/%(program_name)s.log
stderr_logfile=/var/log/supervisor/%(program_name)s.log
autorestart=true
user=mongodb
priority=100

[program:server]
priority=10
directory=/data/code/
command=python3 server.py
;command=/data/code/venvs/cleverInvest/bin/python /data/code/server.py
user=root
autostart=true
autorestart=true

[program:cleverinvest]
priority=10
directory=/data/code/
command=python3 main.py
;command=/data/code/venvs/cleverInvest/bin/python /data/code/main.py
user=root
autostart=true
autorestart=true

我的脚本文件中也有一个语法错误。在纠正它们之后，它起作用了。
