I am having a remote server to which i connect using ssh. I started a process(mongodb) on the server using following command- "/usr/bin/mongod --dbpath /mnt/ebs-300/mongodb --logpath /mnt/ebs-300/log/mongodb/mongodb.log run --config /etc/mongodb.conf &"

As '&' is appended to the command this process runs in the background. After running the process and checking its working properly i exit from the teminal(ssh). This process got killed after some time by printing the below logs - "got kill or ctrl c or hup signal 1 (Hangup), will terminate after current cmd ends"

Can some one please guide me if I am doing wrong or there is proper way to run the process from the remote terminal.

Thanks!!

I would suggest that although '&' runs the command in background, when you exit your terminal it is still getting sent SIGHUP. You could use the disown command

disown prevents the current shell from sending a HUP signal to each of the given jobs when the current shell terminates a login session.

If job is omitted, the most recently started or stopped background job is used.

  • Thanks Rory for the reply. As I don't know much about linux process I need to clear a doubt that according to you even when i exit the terminal it is still getting SIGHUP which is killing the process. To avoid this you said to use disown that ok, but can i also handle this case by using 'nohup' i.e. i would run the process like _ "nohup /usr/bin/mongod --dbpath /mnt/ebs-300/mongodb --logpath /mnt/ebs-300/log/mongodb/mongodb.log run --config /etc/mongodb.conf > /dev/null &" Will it work ? – azhar_salati Aug 26 '11 at 08:01
  • The '&' should be all you need for a nohup (it is equivalent), but it can still be killed if the terminal exits. – Rory Alsop Aug 26 '11 at 08:10

Rory's answer is fine, but adding the --fork flag to your mongod invocation will keep it running in the background as well.

This is what nohup is for!

If it exists on your distribution, it's the simple way, plus it lets you keep a logfile.
