This file needs to have execution permissions:
|
1
|
$ sudo chmod +x /etc/init.d/phantomjs |
You can define overridable options in the following file:
/etc/default/phantomjs
|
1
|
WEBDRIVER_PORT=8190 |
If you want the service to start at boot time, type the following command:
|
1
|
$ update-rc.d phantomjs defaults |
And here you go, you can now manage phantomjs using the service start/stop/status commands. Note that the stop command will requires a few seconds to shutdown the process.
