How to start Solr automatically?

Question

At the moment I have to go to /usr/java/apache-solr-1.4.0/example and then do:

java -jar start.jar

How do I get this to start

Answer 1

init.d/solr script that's tested on Centos 6/Amazon Linux. It wraps solr's native CLI.

#!/bin/bash
# description: Starts and stops Solr production


PIDFILE=/var/run/solr.pid
SOLR_HOME=/usr/share/solr
START_COMMAND="$SOLR_HOME/bin/solr start -p 8984 -noprompt -m 1g"
NAME="Solr"


start() {
  echo  "Starting $NAME"
  if [ -f $PIDFILE ]; then
    echo -n "$PIDFILE exists. $NAME may be running."
  else
    str=`$START_COMMAND`
    pid=`echo $str | grep -o "pid=[0-9]*" | grep -o "[0-9]*"`
    if [ "$pid" == "" ];
    then
      echo "[FATAL ERROR] Failed to extract pid. Exiting!"
      exit 1
    fi
    echo $pid > $PIDFILE
  fi
  return 0
}


case "$1" in
  start)
    start
  ;;
  stop)
    echo "Stopping $NAME .."
    $SOLR_HOME/bin/solr stop
    rm -f $PIDFILE
  ;;
  status)
    $SOLR_HOME/bin/solr status
  ;;
  restart)
    $0 stop
    #sleep 2
    $0 start
  ;;

  *)
    echo "Usage: $0 (start | stop | restart | status)"
    exit 1
    ;;

esac
exit $?
