Maybe you need post more infomation in logs so I can find the problem.

Or tell more what's happening when zimg crashed.

hi, “the crazy “

 first, sorry to post this to-do at top of your post list,  because i did not mention the ’to-do’ post thread  at bottom.

 I work at a Chinese internet company, when we deploy service online , we usually deploy it as child process of “supervisor”, this could help when binary crash (avoid losing many pv). 

 refer :http://supervisord.org/ <http://supervisord.org/> 

 further, when become online service, cdn can help a lot.

 love your work , best wishes~

I have used zimg via supervise in my demo server: http://demo.buaa.us/

So there's no problem.

I tried to add zimg to supervise, but zimg exit quickly. How do you configure the supervisor for zimg?

Thanks.

Use absolute path in your configs and set daemon false.

supervisor config:

[program:zimg]
command=/home/zippo/dev/zimg/bin/zimg /home/zippo/dev/zimg/bin/conf/debug.lua
autorestart=true
user=zippo

zimg config:

is_daemon           = 0
log_name            = '/home/zippo/dev/zimg/bin/log/zimg.log'
root_path           = '/home/zippo/dev/zimg/bin/www/index.html'
admin_path          = '/home/zippo/dev/zimg/bin/www/admin.html'
script_name         = '/home/zippo/dev/zimg/bin/script/process.lua'
img_path            = '/home/zippo/dev/zimg/bin/img'

Thanks. It still got crash when upload image at the same time. So I duplicate the zimg.lua with different tcp port.

das@ubuntu:/etc/supervisor/conf.d$ cat app.conf [program:zimg] command=/opt/zimg/bin/zimg /opt/zimg/bin/conf/zimg.lua directory=/opt/zimg/bin autorestart=true user=root

[program:zimg2] command=/opt/zimg/bin/zimg /opt/zimg/bin/conf/zimg2.lua directory=/opt/zimg/bin autorestart=true user=root

[program:zimg3] command=/opt/zimg/bin/zimg /opt/zimg/bin/conf/zimg3.lua directory=/opt/zimg/bin autorestart=true user=root

[program:zimg4] command=/opt/zimg/bin/zimg /opt/zimg/bin/conf/zimg4.lua directory=/opt/zimg/bin autorestart=true user=root

So I have 4 zimg running on different tcp port.

root@ubuntu:/etc/supervisor/conf.d# ps -ef | grep zimg root 1146 1139 0 23:23 ? 00:00:00 /opt/zimg/bin/zimg /opt/zimg/bin/conf/zimg3.lua root 1147 1139 0 23:23 ? 00:00:00 /opt/zimg/bin/zimg /opt/zimg/bin/conf/zimg2.lua root 1148 1139 0 23:23 ? 00:00:00 /opt/zimg/bin/zimg /opt/zimg/bin/conf/zimg.lua root 1149 1139 0 23:23 ? 00:00:00 /opt/zimg/bin/zimg /opt/zimg/bin/conf/zimg4.lua root 1171 1089 0 23:24 pts/0 00:00:00 grep --color=auto zimg
