Introduction:

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

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.

Weight:Use weight setting to balance.

LeastConn:Search least conn server to balance server.

Install:

  go get github.com/matishsiao/GoHAProxy
  go test
  go build

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.)
