【问题描述】：

我花了 6 个小时试图找出它为什么不起作用。真的不知道为什么。提前致谢！

注意：以下设置在 ubuntu 服务器上完美运行，但在我的本地 MacOSX 上失败

这是我的 supervisord.conf：

;local conf

[unix_http_server]
file=/var/run/supervisor.sock   ; (the path to the socket file)

[supervisord]
logfile=/tmp/supervisord.log ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB        ; (max main logfile bytes b4 rotation;default 50MB)
logfile_backups=10           ; (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=false               ; (start in foreground if true;default false)
minfds=1024                  ; (min. avail startup file descriptors;default 1024)
minprocs=200                 ; (min. avail process descriptors;default 200)
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL  for a unix socket

[include]
files = conf.d/*.conf

这是我的 conf.d 文件夹下的 tornado.conf：

[group:tornadoes]
programs=tornado-8000,tornado-8001,tornado-8002,tornado-8003

[program:tornado-8000]
command=python /Users/horace/server/server.py --port=8000
directory=/var/www
user=www-data
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/tornado.log
loglevel=info

[program:tornado-8001]
command=python /Users/horace/server/server.py --port=8001
directory=/var/www
user=www-data
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/tornado.log
loglevel=info

[program:tornado-8002]
command=python /Users/horace/server/server.py --port=8002
directory=/var/www
user=www-data
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/tornado.log
loglevel=info

[program:tornado-8003]
command=python /Users/horace/server/server.py --port=8003
directory=/var/www
user=www-data
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/tornado.log
loglevel=info

运行后

sudo supervisord -n -edebug

我得到了这些日志。

注意：我看到了“ImportError: No module named tornado.httpserver”错误。但是当我尝试从带有“

的文件夹中运行 server.py

python server.py --port=8000

服务器启动没有任何问题。为什么supervisord无法启动它，这让我很困惑。

更新：我不知道为什么，但我通过以下方式启动了服务器：

su root

然后启动supervisord。一切运行正常。但是还是不知道为什么在我的普通用户horace下，我无法启动它。（导入 tornado.httpserver 模块）

sudo supervisord

有人知道原因吗？谢谢。

【问题讨论】：

tornado 在你的全局 python 路径中吗？还是只是在您应用的文件夹中？
users/Horace/server 文件夹中有tornado 文件夹吗？
是的。我在服务器文件夹下拥有所有的 tornado server.py 文件。我可以手动启动它
@horacex: 你可以手动启动它作为用户 www-data 吗？
我可以。使用相同的命令：python server.py --port=8000.

【解决方案1】：

您是否尝试设置environment=PYTHONPATH="..." 变量？

编辑：

supervisor.conf：

[include]
files = *.supervisor

[supervisord]

[supervisorctl]
serverurl = unix://supervisord.sock

[unix_http_server]
file = supervisord.sock

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

app1.supervisor：

[program:app1]
process_name = app1-%(process_num)s
environment = PYTHONPATH="%(here)s/apps/env/current"
command = python -m apps.app1 --port=%(process_num)s
#--log_file_prefix=app.log                                                                                  
# Increase numprocs to run multiple processes on different ports.                                                   
# Note that the chat demo won't actually work in that configuration                                                 
# because it assumes all listeners are in one process.                                                              
numprocs = 2
numprocs_start = 8000

【解决方案2】：

您的 supervisord 配置文件看起来不错。

对我来说缺少的是在服务器上的 virtualenv 中运行主管。

我在运行 supervisord -c my_conf_file 之前添加了 virtualenv source mydir/bin/activate 行，这很有效。
