nacos无缝替换eureka

首先安装好nacos之后直接引入客户端依赖和配置文件，同时把eureka的内容去掉

从nacos官网 https://nacos.io/zh-cn/index.html 下载安装包
下载好之后解压，打开配置文件 conf/application.properties 配置一下mysql和地址，其他的的按需配置

server.port=8848
spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://db:port/nacos-config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user=root
db.password=root

nacos集群地址

vim conf/cluster.conf
192.168.1.2:8848
192.168.1.3:8848

配置之后启动就好了

./startup.sh
./startup.sh-m standalone  //如果是单机带个参数

注意spring cloud 版本问题，如果不对会出现一些不兼容
