在EC2 Linux（CentOS）上重新启动时自动启动过程

Question

I want to make sure that a web service starts automatically when my AWS EC2 Linux machine is rebooted.

To start manually the process I need to type the following commands:

sudo su
cd /root/notebooks
nohup jupyter notebook &

I edited the /etc/rc.local as per below, but the process never starts. Any ideas?

#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

sudo su

cd /root/notebooks

nohup jupyter notebook &

touch /var/lock/subsys/local

Answering considering Ubuntu OS, The easiest and the best solution (though with this it will run even when the server is stopping, but that is not an issue here):

1. Go to /etc/init.d
2. Create a bash script (using vim script don't give an extension) in that directory and enter the content as follows:

 sudo su cd /root/notebooks nohup jupyter notebook & 

Now, within that directory itself, run the following commands:

 chmod +x script update-rc script defaults 

You're done. If you're using 16.04 ubuntu, use update-rc.d.
