nacos启动报错：org.springframework.context.ApplicationContextException: Unable to start web server

nacos启动报错：

org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat 
        at org.springframework.boot.web.servlet.context.ServletWebServerApplicationContext.onRefresh(ServletWebServerApplicationContext.java:156)

解决方案：nacos默认为集群模式启动，在启动文件startup.cmd中第28行修改保存配置为单例模式启动就可以了
