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
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:
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
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
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
web浏览器访问：
http://localhost/config/now
查看数据库：
至此window上的nacos的集群与持久化配置完成。
