我的nacos版本1.4.2，也许从我这个版本之后下面的配置就不够用了 

spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://localhost:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&serverTimezone=UTC
db.user=root
db.password=youdontkonw

spring.datasource.platform=mysql

db.num=1
db.url.0=jdbc:mysql://11.162.196.16:3306/nacos_devtest?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=nacos_devtest
db.password=youdontknow

观察application.properties配置文件，发现原来官方给出了Mysql连接的实例

### 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?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
# db.user.0=nacos
# db.password.0=nacos

因此为了搭建集群，需将配置信息做如下更改

spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://localhost:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&serverTimezone=UTC
db.user=root
db.password=youdontkonw

 usessh默认是false
