Supervisor monitors gearman tasks

To install a supervisor, you can directly use Yum install supervisord. However, the version may be earlier. Refer to the official method:

easy_install supervisor

Http://supervisord.org/installing.html#installing-to-a-system-with-internet-access

Add service, VIM/etc/init. d/supervisord, and modify the file attributes to execute chmod 777/etc/init. d/supervisord.

Join the gearman task. The following is the task pushed by Baidu cloud.

Vim/etc/supervisord. conf

[program:APNS_PUSH]command=/usr/bin/php /data2/www/web/apns/worker_origin.phpprocess_name=APNS_PUSH_%(process_num)snumprocs=2autostart=trueautorestart=trueuser=nginxstdout_logfile=/data2/log/push/push_%(process_num)s.logstderr_logfile=/data2/log/push/push.error.log

Start gearman, start supervisord, PS-Ef | grep XXX, and check whether the task has been executed.

You can also use gearman-monitor to view the gearman task status.
