I am using Centos 7 and on boot I would like to:
- Make a screen
- Execute a command: osrm-routed –algorithm=MLD ~/osrm-backend/profiles/australia-latest.osrm
- Detatch from screen (possibly not needed, just as long as I can access it myself after its running in future)
Here is something I have thought about, although not correct and wont work
filename: mapstart.sh Contents of file:
#!/bin/bash /usr/bin/screen -dmS mapapi osrm-routed --algorithm=MLD ~/osrm-backend/profiles/australia-latest.osrm
With your help with the script. I am not sure the best way to run that on boot with centos 7.
Appreciate your help and input.

Answer
For those who would like to know. The issue was with OSRM and centos. I was able to get it running using the full paths of everything and the following in crontab -e
To get the full path of osrm-backend i ran the command of:
which osrm-routed
It returned the result of:
/usr/local/bin/osrm-routed
That then enabled me to add the full path of the command I was trying to run from crontab -e which is required. From there it worked running the below in crontab -e
@reboot /usr/bin/screen -dm -S pistartup /usr/local/bin/osrm-routed --algorithm=MLD ~/osrm-backend/profiles/australia-latest.osrm
break down of all the above:
runs command at reboot only:
@reboot
full path to screen command:
/usr/bin/screen
create screen with name of pistartup and detach:
-dm -S pistartup
my particular command i wanted to run inside the screen:
/usr/local/bin/osrm-routed --algorithm=MLD ~/osrm-backend/profiles/australia-latest.osrm
Now when ever the machine is rebooted. it has created a screen and run my command. To resume the screen manually If i ever wanted to, i could issue the command of:
screen -r pistartup
