如何在不使用 root 的情况下运行 supervisord？

Question

我似乎无法弄清楚为什么 supervisord 不会以非 root 用户身份运行。如果我在用户设置为 jason (pid 1000) 的情况下启动它，我会在日志文件中得到以下信息：

2010-05-24 08:53:32,143 CRIT Set uid to user 1000
2010-05-24 08:53:32,143 WARN Included extra file "/home/jason/src/tsched/celeryd.conf" during parsing
2010-05-24 08:53:32,189 INFO RPC interface 'supervisor' initialized
2010-05-24 08:53:32,189 WARN cElementTree not installed, using slower XML parser for XML-RPC
2010-05-24 08:53:32,189 CRIT Server 'unix_http_server' running without any HTTP authentication checking
2010-05-24 08:53:32,190 INFO daemonizing the supervisord process
2010-05-24 08:53:32,191 INFO supervisord started with pid 3444

...然后该过程因某种未知原因而终止。如果我在没有 sudo 的情况下启动它（在用户 jason 下），我会得到类似的输出：

2010-05-24 08:51:32,859 INFO supervisord started with pid 3306
2010-05-24 08:52:15,761 CRIT Can't drop privilege as nonroot user
2010-05-24 08:52:15,761 WARN Included extra file "/home/jason/src/tsched/celeryd.conf" during parsing
2010-05-24 08:52:15,807 INFO RPC interface 'supervisor' initialized
2010-05-24 08:52:15,807 WARN cElementTree not installed, using slower XML parser for XML-RPC
2010-05-24 08:52:15,807 CRIT Server 'unix_http_server' running without any HTTP authentication checking
2010-05-24 08:52:15,808 INFO daemonizing the supervisord process
2010-05-24 08:52:15,809 INFO supervisord started with pid 3397

......它仍然没有运行。如果有帮助，这是我正在使用的 supervisord.conf 文件：

[unix_http_server]
file=/tmp/supervisor.sock   ; path to your socket file

[supervisord]
logfile=./supervisord.log ; supervisord log file
logfile_maxbytes=50MB       ; maximum size of logfile before rotation
logfile_backups=10          ; number of backed up logfiles
loglevel=debug ; info, debug, warn, trace
pidfile=./supervisord.pid ; pidfile location
nodaemon=false              ; run supervisord as a daemon
minfds=1024                 ; number of startup file descriptors
minprocs=200                ; number of process descriptors
user=jason ; default user
childlogdir=./supervisord/            ; where child log files will live


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

[supervisorctl]
serverurl=unix:///tmp/supervisor.sock ; use unix:// schem for a unix sockets.

[include]

# Uncomment this line for celeryd for Python
files=celeryd.conf

# Uncomment this line for celeryd for Django.
;files=django/celeryd.conf

...这是celeryd.conf：

[program:celery]
command=bin/celeryd --loglevel=INFO --logfile=./celeryd.log

environment=PYTHONPATH='./tsched_worker',
            JIVA_DB_PLATFORM='oracle',
            ORACLE_HOME='/usr/lib/oracle/xe/app/oracle/product/10.2.0/server',
            LD_LIBRARY_PATH='/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib',
            TNS_ADMIN='/home/jason',
            CELERY_CONFIG_MODULE='tsched_worker.celeryconfig'

directory=.
user=jason
numprocs=1
stdout_logfile=/var/log/celeryd.log
stderr_logfile=/var/log/celeryd.log
autostart=true
autorestart=true
startsecs=10

; Need to wait for currently executing tasks to finish at shutdown.
; Increase this if you have very long running tasks.
stopwaitsecs = 600

; if rabbitmq is supervised, set its priority higher
; so it starts first
priority=998

谁能帮我弄清楚发生了什么？

我自己对监督很陌生，但我也在尝试让它与 celeryd 一起工作。现在我很高兴supervisord能够以root身份运行，因为它是通过init.d脚本运行的，请注意。

无论如何，请查看Supervisord 的日志和错误日志文件。里面有什么？在 Ubuntu 10.10 上，它们位于/var/log/supervisor/supervisord.log. 您可以在supervisorctl中使用命令“maintail”来查看。
