最近在开发过程中遇到一个问题，就是两个项目都有nacos，但是无法同时启动两个nacos。

下面直接干饭

1.新建文件夹nacos1

我的nacos日志文件在C:Usersxbx下面，原本只有nacos，nacos1是自己新建的文件夹。

2.application.yml

改成nacos1

server:
  servlet:
    contextPath: /nacos1
  tomcat:
    accesslog:
      enabled: true
      pattern: %h %l %u %t "%r" %s %b %D %{User-Agent}i %{Request-Source}i
    basedir: 
spring:
  datasource:
    platform: mysql
db:
  num: 1
  password:
    0: ${MYSQL-PWD:xbx123}
  url:
    0: jdbc:mysql://${MYSQL-HOST:127.0.0.1}:${MYSQL-PORT:3306}/${MYSQL-DB:nacos}?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true
  user:
    0: ${MYSQL-USER:root}
management:
  metrics:
    export:
      elastic:
        enabled: false
      influx:
        enabled: false
nacos:
  core:
    auth:
      caching:
        enabled: true
      default:
        token:
          expire:
            seconds: 18000
          secret:
            key: SecretKey012345678901234567890123456789012345678901234567890123456789
      enabled: false
      system:
        type: nacos
  istio:
    mcp:
      server:
        enabled: false
  naming:
    empty-service:
      auto-clean: true
      clean:
        initial-delay-ms: 50000
        period-time-ms: 30000
  security:
    ignore:
      urls: /,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-ui/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**
  standalone: true

3.JeecgNacosApplication

改成新建文件夹nacos1的路径

package com.alibaba.nacos;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

import javax.servlet.http.HttpServletResponse;

/**
 * Nacos 启动类
 *
 * @author zyf
 */
@SpringBootApplication(scanBasePackages = "com.alibaba.nacos")
@ServletComponentScan
@EnableScheduling
public class JeecgNacosApplication {

    /**
     * 是否单机模式启动
     */
    private static String standalone = "true";

    /**
     * 是否开启鉴权
     */
    private static String enabled = "false";

    public static void main(String[] args) {
        System.setProperty("nacos.standalone", standalone);
        System.setProperty("nacos.core.auth.enabled", enabled);
        System.setProperty("server.tomcat.basedir","logs");
        //自定义启动端口号
        System.setProperty("server.port","18848");
        System.setProperty("nacos.home", "C:\Users\xbx\nacos1");
        SpringApplication.run(JeecgNacosApplication.class, args);
    }

    /**
     * 默认跳转首页
     *
     * @param model
     * @return
     */
    @GetMapping("/")
    public String index(Model model, HttpServletResponse response) {
        // 视图重定向 - 跳转
        return "/nacos";
    }
}

这样就可以启动了
