Im trying to start kibana 4 as a service in ubuntu 12.04. Please any one help on how to set as service .
I referred these links to write the script , but it wont work.
https://github.com/akabdog/scripts/blob/master/kibana4_init
https://github.com/chovy/node-startup/blob/master/init.d/node-app
Below code is worked for me.

Small error with the script.In the LogFile path you need to specify at the end .log
There seems to be a small error in the init script. The PID_FILE varible uses the $NAME varible but NAME isn't defined until later. Move the NAME variable before the PID_FILE variable.

I have install elasticsearch 2.3.3 in centos 7 but after closing terminal elasticsearch plugin head automatically close but I want keep running in background. please give me helpful answer.
You can run it in background as two ways,
1. Nohup
2. Creating service script and put it in init.d folder
Nohup
Eg: nohup ./bin/elasticsearch
Service script
Use the following script,
#!/bin/bash
### BEGIN INIT INFO

The problem, as noted in this related ticket, is that Chef checks the "status" of a service and will not start it if the "status" command returns an exit code of "0". Which it always does because the script itself completes successfully, regardless of whether the service is running or not.
I need to adapt my init script to return an exit code of 3 if the service is not running, per the guidelines for Init scripts posted here:
0 program is running or service is OK
1 program is dead and /var/run pid file exists
2 program is dead and /var/lock lock file exists
3 program is not running
4 program or service status is unknown
5-99 reserved for future LSB use
100-149 reserved for distribution use
150-199 reserved for application use
200-254 reserved
I modified my initial script to:
#!/bin/bash
# description: Tomcat6 service
# processname: java
# chkconfig: - 99 1
# Source function library.
. /etc/init.d/functions
# Source sysconfig for tomcat6
if [ -f /etc/sysconfig/tomcat6 ]; then
. /etc/sysconfig/tomcat6
fi
[ -d "$CATALINA_HOME" ] || { echo "Tomcat requires $CATALINA_HOME."; exit 1; }

case $1 in

if su $TOMCAT_USER bash -c "cd $CATALINA_HOME/logs; $CATALINA_HOME/bin/catalina.sh $1"; then
echo -n "Tomcat $1 successful"
[ $1 == "stop" ] && rm -f $CATALINA_PID
else
echo -n "Error in Tomcat $1: $?"
exit_var=1
fi

restart)
$0 start
$0 stop

status)
if [ -f "$CATALINA_PID" ]; then
read kpid < "$CATALINA_PID"
if ps --pid $kpid 2>&1 1>/dev/null; then
echo "$0 is already running at ${kpid}"
exit_var=0
else
echo "$CATALINA_PID found, but $kpid is not running"
exit_var=4
fi
unset kpid
else
echo "$0 is stopped"
exit_var=3 # Fixes issue with Chef not starting a stopped service.
fi
;;
esac
exit $exit_var
But those aren't ACTUALLY changing the exit codes for the script. How can I set different exit codes for different case scenarios?
Version Info:
OS: CentOS 6.5
Chef: 10.20
Tomcat: 6.0.39
You have the right idea, but you have exit_var=3 in the wrong place. I have placed it below to equal 3 for the status when it is already running:
status)
if [ -f "$CATALINA_PID" ]; then
read kpid < "$CATALINA_PID"
if ps --pid $kpid 2>&1 1>/dev/null; then
echo "$0 is already running at ${kpid}"
## Fixes issue with Chef not starting a stopped service.
exit_var=3 ## this is the condition of already running
else
echo "$CATALINA_PID found, but $kpid is not running"
exit_var=4
fi
unset kpid
else
echo "$0 is stopped"
exit_var=5 # (renumbered 5 set as you desire)

I'm trying to write init.d script to run solr as daemon, but unfortunately ps aux shows that there is no such process.
Here is the code:
#!/bin/sh
start_path=/opt/solr/example/start.jar
JAVA_PATH=/usr/bin/java
PID=/tmp/.solr/pid
ARGS="-jar $start_path"
if [ ! -d /tmp/.solr ]
then
mkdir /tmp/.solr
fi
start(){
echo -n "Starting solr..."
start-stop-daemon --start --background --name "solr" --make-pidfile --pidfile $PID --exec ${JAVA_PATH} -- ${ARGS}
RETVAL="$?"
if [ "$RETVAL" = 0 ]
then
echo "done."
else
echo "failed. See error code for more information."
fi
return $RETVAL
}
case "$1" in
start)
start
;;

echo $"Usage: solr {start}"
exit 3

How about using the command
java jar start.jar & disown
This would start the process and move it to the background...
Hope I helped!
Well, thanks to this blog post, I finally made it.
Here's how it looks:
#!/bin/sh
PIDFILE=/tmp/.solr/pid
if [ ! -d /tmp/.solr ]
then
mkdir /tmp/.solr
fi
cd /opt/solr/example
start(){
if [ ! -f $PIDFILE ]
then
echo "Starting solr..."
nohup java -jar start.jar &
echo $! > $PIDFILE
RETVAL=$?
if [ "$RETVAL" = 0 ]
then
echo "Done."
else
echo "Failed. See error code for more information."
fi
return $RETVAL
echo $! > $PIDFILE
else
echo "Solr is already running"
return 1
fi
}
stop(){
if [ ! -f $PIDFILE ]
then
echo "Solr is not running"
return 1
else
PID=$(cat $PIDFILE)
echo "Stopping solr..."
kill $PID
RETVAL=$?
if [ "$RETVAL" = 0 ]
then
echo "Solr stopped."
rm $PIDFILE
else
echo "Can't stop Solr."
fi
return $RETVAL
fi
}
restart(){
stop
start

I have a Gradle app that I startup using ./gradlew run. This works fine, but I'm trying to deploy to an AWS instance (Ubuntu 12) and I would like the script to execute on boot. I tried writing a startup.sh file with the above command, but no dice. I've also tried adding the command to the /etc/rc.local file, but that doesn't seem to work either. Can someone give me an idea as to how to execute `./gradlew run' on startup? Thanks!
I wrote the following init script for starting gradle applications at system startup for redhat distros (centos/fedora etc).
You need to perform a few steps to tie it all together:
deploy your gradle application using gradle distZip onto your target server
create a configuration file /etc/my-service.conf
link the init script (see below) to the service name in /etc/init.d/my-service
An example configuration file /etc/my-service.conf
username=someunixuser
serviceName=MyStandaloneServer
prog="/path/to/bin/MyStandaloneServer -a any -p params -y you -w want"
javaClass="some.java.MyStandaloneServer"
Note the path to the application from the distZip in the prog line.
You then link the init script to the actual service you want it to be run as, e.g.
ln -s /path/to/gradle-init-start-stop /etc/init.d/my-service
Once you've done this, you can use chkconfig to add the service in the usual way (it defaults to 3/4/5)
Here is the script gradle-init-start-stop
#!/bin/bash
#
# chkconfig: 345 80 20
# description: Start and stop script for gradle created java application startup
#
# This is a generic file that can be used by any distribution from gradle ("gradle distZip").
# Link this file to the name of the process you want to run.
# e.g.
# ln -s /path/to/gradle-init-start-stop /etc/init.d/ivy-jetty
#
# it requires a conf file /etc/NAME.conf, e.g. /etc/ivy-jetty.conf
# otherwise it will quit.
#
# CONFIGURATION FILE ENTRIES:
# ---------------------------
# username=process-owner
# prog="/path/to/gradle-startscript -a any -e extra parameters"
# serviceName=SomeShortNameForService
# javaClass=package.for.JavaClass

I found this small shell script in a book... NGiNX works it just this script that just does not work. Because every time I do /etc/init.d/nginx start (that is where the file is) it sends me this message: Usage: /etc/init.d/nginx {start|stop|restart|reload}
For testing purposes I added a echo "$1" and it sends me -e when I do: /etc/init.d/nginx start Or anything else...
I am using Ubuntu 12.04.

set –e is setting the list of arguments to the script to –e. Remove that line and the script will work.
Edit: The script posted contains set –e (that is EN DASH + e) as opposed to set -e (ASCII hyphen/minus sign + e). This caused sh to override the first argument passed with –e instead of setting the -e option in the shell. Replacing – with - should fix the problem.
