Good news guys, spynner works for me. It’s a pain to set up, but here are the steps:
This solution won’t help you with Morph, but if you’re running an Ubuntu server, this works.
This explanation is a ramble, but I wanted to get my thoughts down somewhere.
Set up Spynner’s dependencies - qt4 (which has it’s own dependencies).
If you’re using a linux distro, do this http://www.guguncube.com/2733/python-spynner-installation-in-ubuntu
I ignored the quick install and did one and two of ‘step by step’.
If you get this error when installing the packages
error: Setup script exited with error: command 'x86_64-linux-gnu-gcc' failed with exit status 1, then you need to install
sudo apt-get install python-dev
To get qt4 working on a vps, you’re going to need X11 forwarding.
I found X11 the hardest part to get working, so here are some informative articles.
In those explainers is details about Forwarding.
You need to add these lines this file
/etc/ssh/sshd_config, if you’re logging into the VPS via ssh, and want to see what’s going on.
X11Forwarding yes X11UseForwarding yes X11DisplayOffset 10
If you’re running your script while not logged into SSH, you’ll need to set X11DisplayOffset to 0
If you’re using Linux and testing a spynner script on a VPS via SSH, you need to login as
ssh -X user@ip_address. If you don’t use -X you’ll get,
cannot connect to X server when you try to run a script that contains spynner.
To run the spynner script as a cron job, when you’re not logged into the VPS, you’ll need to add first give authority to the user’s account that is running the job, for it to open the X server.
You should make sure that Xvfb is installed.
Also, install xvfbwrapper, and refer to the basic usage example for putting your code inside the X server.
You can make your python script executable - pay attention to line endings.
Here is my cron job.
29 17 * * * export DISPLAY=:0 XAUTHORITY=/home/vp_server/.Xauthority && /home/vp_server/WebWatcher/WebWatcher.py
But if I was running this job while logged into the SSH, and wanted to see it run, I’d need to have DISPLAY=:10 and the Forwarding options turned on.
