Run multiple elasticsearch nodes as a service on one Ubuntu-Server

I gave up after a while, removed the elasticsearch repo-installation and downloaded the zip-file instead. Then I created two upstart-jobs and everythings works smoothly so far.

1. Wrapper

    description "Start several ES-instances at once (this is a wrapper)."    start on (local-filesystems and net-device-up IFACE!=lo)    stop on runlevel [06]     respawn    # Give up respawn if restart occurs 5 times in 120 seconds    respawn limit 5 120    env NUM_INSTANCES=4    pre-start script        for i in $(seq 1 $NUM_INSTANCES)        do            start elasticsearch-instance ID=$i        done    end script    pre-stop script        curl -XPOST "http://localhost:9200/_cluster/nodes/_local/_shutdown"    end script

2. Instances

    description "starts up an elasticsearch instance (node)"    stop on stopping elasticsearch    respawn    instance $ID    limit nofile 64000 64000    setuid elasticsearch    setgid elasticsearch    env JAVA_OPTS="-XX:+UseCompressedOops"    env ES_HEAP_SIZE=28G    exec /data/elasticsearch/bin/elasticsearch -Des.config=/data/elasticsearch/config/elasticsearch.yml

Assuming your rpm or deb created an init.d script, to start a second node on the same machine do as follows:

cd /etc/init.dcp --preserve elasticsearch elasticsearch2

Edit elasticsearch2 script:

1. change # elasticsearch to # elasticsearch2
2. add node="2" after line prog="elasticsearch"
3. change pidfile=/var/run/elasticsearch/${prog}.pid to pidfile=/var/run/elasticsearch/${prog}${node}.pid
4. change lockfile=/var/lock/subsys/$prog to lockfile=/var/lock/subsys/$prog$node
5. change echo -n $"Starting $prog: " to echo -n $"Starting $prog: (node $node)"
6. change echo -n $"Stopping $prog: " to echo -n $"Stopping $prog: (node $node)"

Save the file. Execute

chkconfig --add elasticsearch2service elasticsearch2 start
