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

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.php
Process_name = APNS_PUSH _ % (process_num) s
Numprocs = 2
Autostart = true
Autorestart = true
User = nginx
Stdout_logfile =/data2/log/push _ % (process_num) s. log
Stderr_logfile =/data2/log/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.
