I'm using Ubuntu 12.04.

I've tested several scripts that try to get bitcoind running on startup but none have worked out for me.

I'm getting a little bit desperate because I can't even get bitcoind running once I exit my SSH session.

Any clues on how to get bitcoind running once I exit the SSH session?

Best Regards,

  • bitcoind -daemon? Otherwise, what version of bitcoind are you using, and what do you see in debug.log? – Nate Eldredge Nov 12 '13 at 13:34
  • the last line of debug.log. addcon thread interrupt opencon thread interrupt msghand thread interrupt dumpaddr thread stop Flush(false) DBFlush(false) ended 0ms StopNode() net thread interrupt ERROR: CAddrman::Write() : open failed Flushed 11563 addresses to peers.dat 37ms – André Nov 12 '13 at 13:46

    I tried to run with bitcoind -daemon but onde I exit the SSH session the bitcoind stops – André Nov 12 '13 at 13:47
  • @André how do you know it stops? – Loourr Nov 12 '13 at 14:14
  • @Loour, when I telnet the host on 8332 not answer anymore. If I enter again the shell is not running anymore. I've also discovered that when I run "bitcoind -daemon &" the process goes to the pid(example) 12994, but one minute later the pid is on 12995. For this reason when I close the SSH this pid go away. Any clues? – André Nov 12 '13 at 14:29

You could use screen or a similar tool like tmux or byoblu. Otherwise use the NOHUP command.

nohup is a POSIX command to ignore the HUP (hangup) signal. The HUP signal is, by convention, the way a terminal warns dependent processes of logout. Output that would normally go to the terminal goes to a file called nohup.out if it has not already been redirected. nohup is a low-level utility simply configuring a command to ignore a signal. As seen below, nohup is very far from being a full-featured batch system solving all the problems of running programs asynchronously.

$ nohup abcd &

$ exit

Alternatives: The screen or tmux command can also detach a process from the current shell. It allows to reattach to the process later on. e.g. the following call will run somescript.sh detached from SIGHUP and in the background:

$ screen -A -m -d -S somename ./somescript.sh &


My advice is to learn to use screen (or tmux) so you can later re-attach the process to the main shell and interact with it.
