You will require hubot integrated with outside site - ex) JIRA etc…

daemonize hubot

Install forever

$ sudo npm install --save forever

$ forever --version
v0.15.1

set path as not root user.

$ echo 'export PATH=$PATH:/home/<user>/mybot/node_modules/forever/bin' >> ~/.bashrc
$ source ~/.bashrc

• root user too.

// change to super user.
$ sudo su
# echo 'export PATH=$PATH:/home/<user>/mybot/node_modules/forever/bin' >> ~/.bashrc
# source ~/.bashrc
# echo $PATH
.......:/home/<user>/mybot/node_modules/forever/bin:......

Modify bin/hubot

daemonize start hubot - sudo bin/hubot -a slack

$ sudo bin/hubot start

stop daemonized hubot

$ sudo bin/hubot stop

restart hubot

$ sudo bin/hubot restart

check forever list

$ sudo su
# forever list

info:    Forever processes running
data:        uid  command script                           forever pid   id logfile                 uptime

another way stop forever process

• check process. kill -9 process

$ ps aux | grep hubot | grep -v grep

root     31144  0.3  3.1 723820 32392 ?        Ssl  17:58   0:00 /usr/bin/node /home/hu/mybot/node_modules/forever/bin/monitor node_modules/.bin/hubot

// kill forcibly process
$ sudo kill -9 31146

• another one.

# ps aux | grep hubot | grep -v grep | awk '{print "kill -9", $2}' | sh

Thanks.
