apisix-Getting Started

I. Introduction

(I am new to apisix, many functions and components are not very good, so I will try the most basic load balancing function)
(1) dashboard-Routes
Routes are entry points for requests, which define matching rules between client requests and services.A route can be associated with a service (Service) and an upstream (Upstream), a service can correspond to a set of routes, and a route can correspond to an upstream object (a set of back-end service nodes). Therefore, each request matching a route will be processed by the gateway.Proxy to the upstream service bound by the route.
Personal understanding: According to different rules and forwarding rules, forward the api request to the corresponding back-end server.
(2) dashboard-upstream
The upstream (upstream) list contains the created upstream services (ie, back-end services), which can target multiple upstream servicesNodes perform load balancing and health checks.
Personal understanding: configure the ip and port of the back-end service and the weight rules and other configurations

Second, configuration

(1) Prepare two back-end services
Because it is a salted fish, temporarily use nginx to open two http services with different ports to test
nginx's reference configuration file

Then create a file and put some content in the file for easy viewing

mkdir -p /usr/share/nginx/801/hellomkdir -p /usr/share/nginx/802/helloecho "801" >>/usr/share/nginx/801/hello/testecho "802" >>/usr/share/nginx/802/hello/test

Make sure the nginx configuration file is correct, then start nginx

nginx -tnginx

(2) Create an upstream service (upstream)
Name: test
Load Balancing Algorithm: Weighted Round Robin
Upstream Type: Node
Target Node: Hostname 10.0.47.43 Port 801Weight 1
Hostname 10.0.47.43 Port 802 Weight 1
Protocol: http
Other defaults are fine

(3) Create a route
Name: test001
Path/hello/*

Other defaults, next step
Select the upstream service test we just created

Next, do not select any plug-ins, then preview, it should be no problem, click submit
(4) Test
Simply use the curl command to try

10.0.47.42 is the IP address where apisix is ​​deployed
The port is 9080
You can see that 801 and 802 are output respectively (is this successful? Hey)

Three, follow-up

apisix has a lot more content, keep learning

Let me introduce myself first. The editor graduated from Shanghai Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Alibaba in 2018, until now.I know that most junior and intermediate java engineers want to upgrade their skills, they often need to explore their own growth or sign up to study, but for training institutions, the tuition fee is nearly 10,000 yuan, which is really stressful.Self-learning that is not systematic is very inefficient and lengthy, and it is easy to hit the ceiling and the technology stops.Therefore, I collected a "full set of learning materials for java development" for everyone. The original intention is also very simple. I hope to help friends who want to learn by themselves but don't know where to start, and at the same time reduce everyone's burden.Add the business card below to get a full set of learning materials
