Nacos cluster construction of spring cloud microservices

Nacos cluster construction

1. Cluster structure diagram

Official Nacos cluster diagram:

It contains three Nacos nodes, and then a load balancer agent three Nacos. Here, the load balancer can use nginx.

Our planned cluster structure:

Addresses of three nacos nodes:

node

ip

port

nacos1

192.168.150.1

8845

nacos2

192.168.150.1

8846

nacos3

192.168.150.1

8847

The IP here is your own service IP. You don't have to follow mine

2. Build clusters

Basic steps to build a cluster:

  • Build the database and initialize the database table structure
  • Download the nacos installation package
  • Configuring nacos
  • Start the nacos cluster
  • nginx reverse proxy

2.1. Initialize database

Nacos default data is stored in the embedded database Derby, which is not a database available for production.

The best practice officially recommended is to use the highly available database cluster with master-slave mode. For the highly available database with master-slave mode, you can refer to the follow-up master courses of intelligence education.

Here we take the single point database as an example.

First create a new database named nacos, and then import the following SQL:

CREATE TABLE `config_info` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT 'id',
  `data_id` varchar(255) NOT NULL COMMENT 'data_id',
  `group_id` varchar(255) DEFAULT NULL,

2.2. Download nacos

Nacos has a download address on GitHub: https://github.com/alibaba/nacos/tags , you can choose any version to download.

Only version 1.4.1 is used in this example:

2.3. Configure Nacos

Unzip the package to any non Chinese directory, as shown in the figure:

Catalog Description:

  • bin: startup script
  • conf: configuration file

Enter the conf directory of nacos, modify the configuration file cluster.conf.example, and rename it cluster.conf:

Then add content:

127.0.0.1:8845
127.0.0.1:8846
127.0.0.1:8847

Note: the IP here is your own service IP. You don't have to follow mine!

You can view your node IP in the nacos console when a single node is running, and configure the same IP here:

Then modify the application.properties file to add the database configuration

spring.datasource.platform=mysql

db.num=1

db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=root
db.password.0=123

Please configure the database address, user name and password according to the actual situation.

2.4. Startup

Copy three copies of the Nacos folder, named nacos1, nacos2, and nacos3

Then modify the application.properties in the three folders respectively,

nacos1:

server.port=8845

nacos2:

server.port=8846

nacos3:

server.port=8847

Then start three nacos nodes:

startup.cmd

2.5.nginx reverse proxy

Find the nginx installation package provided in the pre class materials:

Unzip to any non Chinese Directory:

Modify the conf/nginx.conf file, and the configuration is as follows:

# Configuring load balancing for upstream
upstream nacos-cluster {
    server 127.0.0.1:8845;
	server 127.0.0.1:8846;
	server 127.0.0.1:8847;
}

server {
    listen       80;
    server_name  localhost;

    location /nacos1 {
        # proxy_pass proxy configuration
        proxy_pass http://nacos-cluster;
    }
}

Then access in the browser: http://localhost/nacos Just.

The application.yml file in the code is configured as follows:

spring:
  cloud:
    nacos:
      server-addr: localhost:80 # Nacos address

2.6. Optimization

  • During the actual deployment, you need to set a domain name for the nginx server as the reverse proxy, so that if a server migrates the nacos client in the future, there is no need to change the configuration
  • Each node of Nacos should be deployed to multiple different servers for disaster recovery and isolation
