我有以下问题：

我想以 Gearman 工人的身份运行 php 脚本，或者准确地说是 5 名工人。这是我的supervisord.conf-addition：

[program:gearman-test-worker]
process_name=%(program_name)s_%(process_num)02d
command=/usr/bin/php /path/to/gearman-jobs/worker.php
numprocs=5
directory=/path/to/gearman-jobs/
stdout_logfile=/var/log/gearman-job-server/supervisord.log
environment=GEARMAN_USER=gearman
autostart=true
autorestart=true
user=gearman
stopsignal=KILL

当我启动它supervisord -n（或在守护程序模式下）时，它只会产生 1 个实例而不是 5 个。消息看起来不错

[root@pc113 gearman-jobs]# supervisord -n
2013-09-03 14:24:58,775 CRIT Supervisor running as root (no user in config file)
2013-09-03 14:24:58,789 INFO /var/tmp/supervisor.sock:Medusa (V1.1.1.1) started at Tue Sep  3 14:24:58 2013

2013-09-03 14:24:59,858 INFO success: gearman-test-worker entered RUNNING state, process has stayed up for > than 1 seconds (startsecs)

并且没有暗示为什么它只产生一个实例。你能帮我吗？

我觉得问题挺简单的，“numprocs”配置项是v3.0才引入的，见http://supervisord.org/configuration.html。

我能够在库存 CentOS 6.x 系统上复制您的问题，该系统在发布方面明显落后。

# supervisord -n

# rpm -qa | grep supervisor
supervisor-2.1-8.el6.noarch

# uname -a

如果我将主管包升级到 3.x（实际上是通过切换到一个古老的 Fedora 系统），一切都会按预期工作（我设置了 3 个工作人员而不是 5 个）。
