Nacos Server cluster construction

Previous article: Nacos Service Registration and Configuration Center

Nacos Server data persistence

1. Download nacos
   nacos-server-1.2.0.tar
   

2. Execute mysql data script
   
   

3. Modify nacos configuration
   
   

4. Restart nacos and create a new namespace

Nacos Server cluster construction

1. Modify configuration fileapplication.properties

### Specify local server's IP:
nacos.inetutils.ip-address=127.0.0.1

#*************** Config Module Related Configurations ***************#
### If user MySQL as datasource:
spring.datasource.platform=mysql

### Count of DB:
db.num=1

### Connect URL of DB:
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=root
db.password=root

2. Modify the cluster configuration file and make a copy
   

#it is ip
#example
127.0.0.1:8848
127.0.0.1:8849
127.0.0.1:8850

4. Copy 3 copies of nacos 8848 8849 8850 and modify the ports respectively.
   
5. 
   Start D:\dev\nacos-1\bin separately in cluster mode

# 单列模式
# .\startup.cmd -m standalone
# 集群模式
.\startup.cmd -m cluster

6. Visit http://localhost:8848/nacos/ ports 8849 and 8850 respectively.
   

Register the microservice to the Nacos cluster

• Service provider registers with cluster

1. Modify the configuration of service provider m-service-resume-8083-nacos

server:
  port: 8083

spring:
  application:
    name: m-service-resume

  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8 &serverTimezone=UTC
    username: root
    password: root
  jpa:
    database: MySQL
    show-sql: true
    hibernate:
      naming:
        physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl  #避免将驼峰命名转换为下划线命名
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848,127.0.0.1:8849,127.0.0.1:8850
# 非免密登录需要用户，密码等信息       
#        username: nacos
#        password: nacos
#        enabled: true
        #集群名称
        cluster-name: BJ
        #所属命名空间 命名空间ID
        namespace: 59486577-18d5-459c-94ad-cbdf6f3d9d5a

2. Check the nacos cluster, m-service-resume has been registered in the dev cluster with the namespace
   

• Service consumers register to the cluster

3. Modify m-service-autodeliver-8093-nacos configuration

spring:
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848,127.0.0.1:8849,127.0.0.1:8850
          #集群名称
          cluster-name: BJ
          #所属命名空间
          namespace: 59486577-18d5-459c-94ad-cbdf6f3d9d5a

4. Observation cluster
   
5. Access the consumer interface http://localhost:8093/autodeliver/checkState/1545132
