master-slave

Simple tool for master-slave configure. use Erlang R15B

configure

rel/files/sys.config

you must set:

minimal - minimal nodes for live cluster,

path - path for temp file with nodes list,

master_script - script execute on master node

slave_script - script execute on slave node

dead_script - script execute when cluster is dead

rel/files/vm.args

change name and setcookie here

name must be like "[email protected]"

after compile you can find conf files in

master/releases/1/vm.args

master/releases/1/sys.config

compile

./rebar compile ./rebar generate

usage

copy bottle ./rel/master to every host in cluster

set name for every host in master/releases/1/vm.args

in bottle

start application: ./bin/master start

stop application: ./bin/master stop

When node was started you can connect node to cluster

./bin/master connect [email protected]

get node status: ./bin/master who_am_i -> slave|master

get master node: ./bin/master who_is_master -> 'nodename'|none ( if cluster dead)

get all slaves: ./bin/master who_is_slaves -> ['nodename']

get live nodes: ./bin/master who_is_live -> ['nodename']

get dead nodes: ./bin/master who_is_dead -> ['nodename']

get cluster status: ./bin/master cluster_status -> work|dead
