use zookeeper mangage redis cluster and write to master and read from slave
So ,we should have a ping server,install like this: 1.npm install -g node-redis-failover 2.cd to bin and ./redis-failover -c ../examples/config.json
In the client , use like this:
var YRedis=require('../index');
//four parameters,
//1.zookeeper config
//2.read commands.it can be empty array
//3.write command.it can be empty array
//4.key router function
var yredis=YRedis.getClient({servers:'172.20.0.47:2181',chroot:'/'},['sinter','mget','hgetall','ttl'],['set','incr','incrby','decrby','expire'],function(servers,command,sendArgs,sendCallback){
var len=servers.length;
if(sendArgs[1]){
var key=sendArgs[0];
var val=Buffer.byteLength(key, 'utf8')%len;
console.log('=>',key,val);
return val;
}
return 0;
});
yredis.on('ok',function(){
yredis.SET('aaa',12,function(err,r){
console.log(err,r);
});
yredis.decrby('aaa',-1,function(err,r){
console.log(err,r);
});
yredis.addReadCommands('get');
yredis.get('aaa',function(err,r){
console.log(err,r);
});
yredis.SET('aa',12,function(err,r){
console.log(err,r);
});
yredis.decrby('aa',-1,function(err,r){
console.log(err,r);
});
yredis.get('aa',function(err,r){
console.log(err,r);
});
//console.log(yredis.getServers());
console.log(yredis.getMasterServer().name);
var slaves= yredis.getSlaveServers()||[];
slaves.forEach(function(slave){
console.log(slave.name);
});
});
