1 , preface

After more than 10 days of efforts, the surging gateway has a rough prototype, the latter will continue to update and improve, please continue to pay attention to the development of the dynamic

A new version of surging has also recently been updated

Update content:

1. Extended Zookeeper Package
2. Add Service Metadata
3. Add an API Gateway

Open Source Address: https://github.com/dotnetcore/surging

2. Software Environment

Ide:visual Studio 15.3 Preview, Vscode
Framework:. NET Core 2.0

Dependent programs: Zookeepe, RABBITMQ

Vscode Technical Support:

Zhou Pine (zsbfre)

3.Zookeeper Installation

Zookeeper is a distributed Application coordination Service, is Google's chubby open source implementation, is an important component of Hadoop, CDH version of it is used for namenode coordinated control. And surging is based on zookeeper as the registration center

Installation & Configuration

The official website of Apache provides a lot of mirrors, then find the corresponding version, the latest is 3.3.6

Http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz


Install under Windows

Extract the downloaded zookeeper files to the specified directory

D:\zookeeper>

Modify the Conf to add a zoo.cfg

The contents are as follows:

# The number of milliseconds of each tick heartbeat interval milliseconds each time

ticktime=2000

# The number of ticks that initial

# Synchronization phase can take

initlimit=10

# The number of ticks that can pass between

# Sending a request and getting anacknowledgement

Synclimit=5

# The directory where the snapshot isstored. Mirrored Data location

Datadir=/tmp/zookeeper

# The port at which the clients WillConnect client connection

clientport=2181

Go to the Bin directory and start Zkserver.cmd, this script will start a Java process

D:\ZOOKEEPER>CD bin

D:\zookeeper\>

D:\zookeeper\bin >zkserver.cmd

Start the client run and see for yourself

D:\zookeeper\bin>zkcli.cmd 127.0.0.1:2181

This time zookeeper has been installed successfully,

Refer to the official documentation:

Http://zookeeper.apache.org/doc/trunk/zookeeperStarted.html

4.API Gateway

Surging's API gateway is divided into data monitoring ', service management ', data security, identity authentication, flow control, and shunt control. This section describes the following service management, and other features that will be introduced in the next few articles

Service Management

For the service we need to manage the following actions

Service machine: For the service deployment of the machine, we need the platform for management monitoring, if an exception occurs, through the API gateway to alarm

Metadata: Through metadata we can find annotations of related services, such as name, owner, update time

Related consumption: What consumer clients can call consumption through related consumption

The above operation, can effectively manage the service deployed on each machine, reduce the maintenance of human cost.

The following example shows how to use the

Add the following attribute on the business interface method

Director

Head

Based on zookeeper configuration

  . Usezookeeperroutemanager (New Configinfo ("127.0.0.1:2181"))

For the code has been completed, the API gateway can enter http://localhost:729/for access, and then you will see the following interface

6. Summary

API Gateway has a rough prototype, the following will continue to improve the API gateway, and will refactor zookeeper node management and add file configuration to replace the code. If interested please pay more attention or join QQ Group: 615562965
