Introduction:

This go-ha-proxy is simple reverse proxy using Golang.

Original fork from matishsiao/go-ha-proxy

I have reorganize the project from matishsia to make it work on go1.9.2. Also add some test to it. You could check How to test section to see how to test this project manually. Hope this project will help you to learn golang as it did for me. - Clark Zhang

Version:

version:0.0.2

1.support TCP proxy and you can use round-robin or source mode to HA.

2.health mode supported.

3.monitor server supported.

http://localip:8080

4.command line params supported.

./GoHAProxy -help

5.auto reload config file.When file changed.GoHAProxy will auto reloaded.

6.balance type:RoundRobin,Source,Weight,LeastConn

RoundRobin:auto RR

Source:use source ip to balance service. MAC下可能会导致cpu100%，请慎用。

Weight:Use weight setting to balance.

LeastConn:Search least conn server to balance server.

Install:

  go get github.com/Clark-zhang/go-ha-proxy

How to test (by Clark Zhang)

start two server

cd test

go run go_http_router.go -port=9001

go run go_http_router.go -port=9002

start ha-proxy

go run goHAProxy.go -debug=true

try to fetch data or kill one of the server

curl localhost:9000

Configuration format:

configs in config.json

ProxyList:

  Proxy:

  Src:source ip or domain.

  SrcPort:source port.

  Mode:tcp,health

  Type:RoundRobin,Source,Weight,LeastConn

  KeepAlive:1 second (keep alive server connection.Set zero will allways keep alive.)

  CheckTime:1 second (check health,default value:5 seconds.)

  DstList:Destination server list

     DstNode:

     Name:server name

     Dst:server ip or domain

     DstPort:destination port

     Weight:not use(when Weight HA mode done,will use this arg)

     Check:true or false(check node server health.If you set false,the GoHAProxy will set this server allways health.)
