在远程服务器上连续运行并重新启动python脚本

Question

I have 3-4 python scripts which I want to run continuously on a remote server(which i am accessing through ssh login).The script might crash due to exceptions(handling all the exceptions is not practical now), and in such cases i want to immediately restart the script.
What i have done till now.
I have written a .conf file in /etc/init

chdir /home/user/Desktop/myFolder
exec python myFile.py
respawn

This seemed to work fine for about 4 hours and then it stopped working and i could not start the .conf file.
Suggest changes to this or i am also open to a new approach

Answer 1

Easiest way to do it - run in infinite bash loop in screen. Also it's the worst way to do it:

screen -S sessionName bash -c 'while true; python myFile.py ; done'

You can also use http://supervisord.org/ or daemon by writing init.d script for it http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

Answer 2

If your script is running on an Ubuntu machine you have the very convenient Upstart, http://upstart.ubuntu.com/

Upstart does a great job running services on boot and respawning a process that died.
