#Gconfd 配置中心

---

##简介 golang+etcd语言实现的配置中心功能，客户端目前支持php和golang

---

##架构图

---

编译安装

1,源码编译

git clone https://github.com/Leon2012/goconfd
cd goconfd
make

2,安装etcd

DOWNLOAD_URL=https://github.com/coreos/etcd/releases/download
curl -L ${DOWNLOAD_URL}/${ETCD_VER}/etcd-${ETCD_VER}-linux-amd64.tar.gz -o /tmp/etcd-${ETCD_VER}-linux-amd64.tar.gz
mkdir -p /tmp/test-etcd && tar xzvf     /tmp/etcd-${ETCD_VER}-linux-amd64.tar.gz -C /tmp/test-etcd --strip-components=1

##使用

1,启动etcd

/tmp/etcd

2,编辑agent.toml

hosts = "localhost:2379" #etcd监听地址
save_type=1              #kv保存类型，1为文件，2为共享内存
save_path = "/tmp/goconfd" #kv文件保存目录 
file_ext = "php"           #kv文件保存类型，目前支持php或json
key_prefix= "develop.activity" #监听kv前缀
heartbeat_interval=30  #agent发送心跳包的间隔 

3,启动

cd build
./agent --config agent.toml 
./monitor --config monitor.toml
./dashboard --config dashboard.toml

4, 打开dashboard [打开dashboard][1]

##SDK

1,php

composer require leon2012/goconfd-php-sdk
include_once("../vendor/autoload.php");
use goconfd\phpsdk\Goconfd;
$config = [
    'save_path' => '/tmp/goconfd',
    'key_prefix' => 'develop.activity',
];
$sdk = new Goconfd($config);
$kv = $sdk->get("develop.activity.k1");
if ($kv) {
    echo $kv->getValue();
}

2, GO

go get -u github.com/Leon2012/goconfd
import(
    "github.com/Leon2012/goconfd/sdk"
    "fmt"
)
gconfd, err := sdk.NewGoconfd()
if err != nil {
    fmt.Println(err)
}
k, err := gconfd.Get("develop.activity.k1")
if err != nil {
    fmt.Println(err)
}else{
    fmt.Println(k.Value)
}
