网站开发容易吗,泉州网站建设外包,广州百度推广优化排名,百度网站优化是什么意思本次的集群是启动一个服务的三个不同端口#xff0c;配置如下#xff1a;
一.application.properties
加上下列配置#xff0c;目的是使用自己的mysql数据库#xff1a;
spring.datasource.platformmysql

一.application.properties
加上下列配置目的是使用自己的mysql数据库
spring.datasource.platformmysql
db.num1 db.url.0jdbc:mysql://127.0.0.1:3306/nacos_config?serverTimezoneAsia/ShanghaicharacterEncodingutf8connectTimeout1000socketTimeout3000autoReconnecttrue db.userroot db.passwordroot
注意属性serverTimezoneAsia/Shanghai必须加上,否则报错。
二 .配置不同的端口号
修改bin目录下startup.sh文件需要修改两个地方
新增参数o,表示端口号 2.启动时加上端口号 保存退出。
三、修改cluster.conf 注意①这里的ip不能写成127.0.0.1否则识别不了。②这里的ip是虚拟机固定的ip即使服务重启也不变需要配置
遇见的问题 nacos版本2.2.1启动一个服务的三个不同端口结果发现第一个启动正常启动第二个报错如下
