Question

我有以下问题：

我想运行一个PHP脚本作为一个齿轮工作者，或者作为5个工人来准确。这是我的supervisord.conf-补充：

[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时（或在守护进程模式下）它只会产生1个实例而不是5个。消息看起来很好

[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)

并没有提示为什么它只产生一个实例。你能帮忙吗？

我认为问题很简单，“numprocs”配置项仅在v3.0中引入，请参阅http://supervisord.org/configuration.html。

我能够在库存CentOS 6.x系统上复制您的问题，这在发布方面明显落后。

# supervisord -n
2013-09-14 17:19:52,708 CRIT Supervisor running as root (no user in config file)
2013-09-14 17:19:52,724 INFO /var/tmp/supervisor.sock:Medusa (V1.1.1.1) started at Sat Sep 14 17:19:52 2013

# 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古老的Fedora系统），一切都按预期工作（我设置3个工人而不是5个）。

# supervisord -n

# rpm -qa | grep supervisor
supervisor-3.0-0.5.a10.fc14.noarch

Supervisord只产生一个实例
