(六)springcloud之Nacos集群与持久化配置-3

模块:
1.父工程(管理版本)
2.公共模块:Common-API
3.测试模块:NacosClusterConfigConsumer80
版本:
springboot:2.7.6
springcloud:2021.0.5
spring-cloud-alibaba-dependencies:2021.0.1.0
nacos:2.1.2
nginx反向代理:nginx-1.18.0
注:nacos官方建议使用linux来配置集群,这里只是用来说明简单的配置,所以此配置在windows上了,后期补充Linux的搭建

nacos的配置

三个nacos节点的地址:

节点 ip port
nacos1 127.0.0.1 8840
nacos2 127.0.0.1 8850
nacos3 127.0.0.1 8860
进入nacos的conf目录,修改配置文件cluster.conf.example,重命名为cluster.conf

(六)springcloud之Nacos集群与持久化配置-3_第2张图片

在cluster.conf中添加如下内容

127.0.0.1:8840
127.0.0.1:8850
127.0.0.1:8860

然后修改application.properties文件,添加数据库配置:
(六)springcloud之Nacos集群与持久化配置-3_第3张图片
输入:

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


#*************** Config Module Related Configurations ***************#
### If use 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&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=root
db.password.0=admin
复制三份nacos

在这里插入图片描述
然后分别修改三个文件夹中的application.properties
nacos1:

server.port=8840

nacos2:

server.port=8850

nacos3:

server.port=8860

注:nacos配置集群式port不能式连续的数值
启动三个nacos

D:\Program Files\nacos-server-2.1.2\nacos1\bin>startup.cmd
D:\Program Files\nacos-server-2.1.2\nacos2\bin>startup.cmd
D:\Program Files\nacos-server-2.1.2\nacos3\bin>startup.cmd

配置nginx反向代理

解压到任意非中文目录下

(六)springcloud之Nacos集群与持久化配置-3_第4张图片
修改conf/nginx.conf文件,配置如下:

upstream nacos-cluster {
   server  127.0.0.1:8840;
   server  127.0.0.1:8850;
   server  127.0.0.1:8860;
}

server {
    listen       8848;
    server_name  localhost;

    location /nacos {
        proxy_pass http://nacos-cluster;
    }
}

启动nginx

D:\Program Files\nginx-1.18.0>start nginx.exe

web浏览器访问:
http://localhost:8848/nacos

代码中application.yml文件配置如下:

spring:
  cloud:
    nacos:
      server-addr: localhost:8848 # nginx中的访问地址,本来应该为80端口,但是其他程序占用了,所以改为8848了

根据bootstrap.yml配置
