Motan-OpenResty

Overview

Motan is a cross-language remote procedure call(RPC) framework for rapid development of high performance distributed services.

This project is the OpenResty Motan implementation. Provides OpenResty motan server, motan client.

Features

• Interactive with mulit language through motan2 protocol,such as Java, PHP.
• Provides cluster support and integrate with popular service discovery services like Consul.
• Supports advanced scheduling features like weighted load-balance, scheduling cross IDCs, etc.
• Optimization for high load scenarios, provides high availability in production environment.

Quick Start

Installation

git clone https://github.com/weibocom/motan-openresty.git motan

The quick start gives very basic example of running client and server on the same machine. For the detailed information about using and developing Motan, please jump to Documents. the demo case is in the examples/ directory.

Motan server

1. Create examples/motan-service/sys/MOTAN_SERVER_CONF to config service

;config of registries
[motan.registry.consul-test-motan2]
protocol=consul
host=10.211.55.3
port=8500
registryRetryPeriod=30000
registrySessionTimeout=10000
requestTimeout=5000

;conf of services
[motan.basicRefer.simple_rpc_ref]
group=yf-api-core
registry=consul-test-motan2
serialization=simple
protocol=motan2
version=0.1
requestTimeout=1000
haStrategy=failover
loadbalance=random
filter=accessLog,metrics
maxClientConnection=10
minClientConnection=1
retries=0
application=whos-agent

[motan.service.or_service]
group=idevz-test-static
path=com.weibo.motan.status
registry=consul-test-motan2
version=1
port=1234
protocol=motan2
serialization=simple
basicRefer=simple_rpc_service

2. Write an implementation, create and start RPC Server: examples/motan-service/status.lua.

local setmetatable = setmetatable

local _M = {
    _VERSION = "0.1.0"
}

local mt = {__index = _M}

function _M.new(self, opts)
    return setmetatable({}, mt)
end

function _M.show_batch(self, opts)
    
    return "--> Motan" .. "->not name----->\n" .. sprint_r(opts) .. num

end

return _M

Motan client

1. Create examples/motan-service/sys/MOTAN_CLIENT_CONF to config service for subscribe

;config of registries
[motan.registry.consul-test-motan2]
protocol=consul
host=10.211.55.3
port=8500
registryRetryPeriod=30000
registrySessionTimeout=10000
requestTimeout=5000

;conf of refers
[motan.basicRefer.simple_rpc_ref]
group=yf-api-core
registry=vintage-online
serialization=simple
protocol=motan2
version=0.1
requestTimeout=1000
haStrategy=failover
loadbalance=random
filter=accessLog,metrics
maxClientConnection=10
minClientConnection=1
retries=0
application=whos-agent

[motan.refer.rpc_test]
group=idevz-test-static
path=com.weibo.motan.status
registry=consul-test-motan2
protocol=motan2
serialization=simple
basicRefer=simple_rpc_ref

2. Start call

local singletons = require "motan.singletons"
local serialize = require "motan.serialize.simple"
local client_map = singletons.client_map
local client = client_map["rpc_test"]
local res = client:show_batch({name = "idevz"})
print_r("<pre/>")
print_r(serialize.deserialize(res.body))
