# 1. The problem of not stopping the jupyter service is fixed. | |
# It was caused by the exec problem. More details are found in | |
# https://chris-lamb.co.uk/posts/start-stop-daemon-exec-vs-startas | |
# 2. Previously the jupyter was run as root, but it is changed to | |
# be executed as a non-privilege user like 1000:1000 (UID:GID) | |
# 3. The working dir is added as an argument. | |
# Do NOT "set -e" | |
# PATH should only include /usr/* if it runs after the mountnfs.sh script | |

I just tried using this on a fresh Ubuntu 14.04 server on AWS. It doesn't work fully. The stop
specifically doesn't work. The start
does, but I get no feedback, no "OK" message. But the service is running.
Ok it worked somewhat after I chowned the log file. Also the logging directory needs to be created.
But the stopping sometimes takes a little while. I don't understand the delay. And it sometimes gets completely frozen. Weird.
