Hi, If a jenkins slave's launch method is configured as "launch slave via execution of command on the master", it can be launched by a script. I want to do the following in my launch script:
1) ssh to the slave to install some Linux kernel packages and reboot 2) wait for 2 minutes for the slave to reboot 3) ssh to the slave again and invoke slave.jar The script can successfully install the kernel packages and reboot the slave, but step 3 always fails with the following error: <===[JENKINS REMOTING CAPACITY]===>channel started Ping failed. Terminating ERROR: Unexpected error in launching a slave. This is probably a bug in Jenkinshudson.remoting.RequestAbortedException <http://stacktrace.jenkins-ci.org/search?query=hudson.remoting.RequestAbortedException>: hudson.remoting.RequestAbortedException: java.io.IOException: Unexpected termination of the channel at hudson.remoting.Request.call(Request.java:174) <http://stacktrace.jenkins-ci.org/search/?query=hudson.remoting.Request.call&entity=method> at hudson.remoting.Channel.call(Channel.java:663) <http://stacktrace.jenkins-ci.org/search/?query=hudson.remoting.Channel.call&entity=method> at hudson.slaves.SlaveComputer.setChannel(SlaveComputer.java:349) <http://stacktrace.jenkins-ci.org/search/?query=hudson.slaves.SlaveComputer.setChannel&entity=method> at hudson.slaves.SlaveComputer.setChannel(SlaveComputer.java:317) <http://stacktrace.jenkins-ci.org/search/?query=hudson.slaves.SlaveComputer.setChannel&entity=method> at hudson.slaves.CommandLauncher.launch(CommandLauncher.java:122) <http://stacktrace.jenkins-ci.org/search/?query=hudson.slaves.CommandLauncher.launch&entity=method> at hudson.slaves.SlaveComputer$1.call(SlaveComputer.java:200) <http://stacktrace.jenkins-ci.org/search/?query=hudson.slaves.SlaveComputer$1.call&entity=method> at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: hudson.remoting.RequestAbortedException: java.io.IOException: Unexpected termination of the channel at hudson.remoting.Request.abort(Request.java:299) at hudson.remoting.Channel.terminate(Channel.java:719) at hudson.remoting.SynchronousCommandTransport$ReaderThread.run(SynchronousCommandTransport.java:69) Caused by: java.io.IOException: Unexpected termination of the channel at hudson.remoting.SynchronousCommandTransport$ReaderThread.run(SynchronousCommandTransport.java:50) Caused by: java.io.EOFException The last line of my launch script is: ssh root@192.168.1.100 "java -jar /root/jenkins/slave.jar" If I remove all other lines from the launch script and keep only the above line, the slave can be successfully launched online by the script: [07/13/12 00:18:00] Launching slave agent $ /home/jenkins/scripts/launch.sh <===[JENKINS REMOTING CAPACITY]===>channel started Slave.jar version: 2.16 This is a Unix slave Copied maven-agent.jar Copied maven3-agent.jar Copied maven3-interceptor.jar Copied maven-interceptor.jar Copied maven2.1-interceptor.jar Copied plexus-classworld.jar Copied classworlds.jar Evacuated stdout Slave successfully connected and online I also tried the following launch script: ssh root@192.168.1.100 "uname -a" ssh root@192.168.1.100 "java -jar /root/jenkins/slave.jar" 'uname -a' can be successfully executed but still slave can't be launched, same error as above. I guess it's because stdin/stdout got messed up by other lines before the slave.jar invoking line? Any idea? Thanks in advance. Jenkins version: 1.474 Romu
