下载 nacos 源码

1、只需保留 nacos console 模块，其他模块均可删除

2、console 源码结构说明

├── pom.xml
└── src
    ├── main
    │   ├── java
    │   │   └── com
    │   │       └── alibaba
    │   │           └── nacos
    │   │               ├── Nacos.java  # main 启动类
    │   │               └── console    # 控制台相关源码
    │   └── resources
    │       ├── application.properties  # nacos 配置文件
    │       └── static    # 静态页面目录
    └── test    # 单元测试部分

3、修改application文件

### Default web context path:
server.servlet.contextPath=/nacos

### If use MySQL as datasource:
spring.main.allow-circular-references=true
nacos.naming.empty-service.auto-clean=true
nacos.naming.empty-service.clean.initial-delay-ms=50000
nacos.naming.empty-service.clean.period-time-ms=30000

management.metrics.export.elastic.enabled=false
management.metrics.export.influx.enabled=false

spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://ip:3306/ry-config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user=root
db.password=root

#*************** Access Control Related Configurations ***************#
### The ignore urls of auth, is deprecated in 1.2.0:
nacos.security.ignore.urls=/,/error,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-ui/public/**,/v1/auth/**,/v1/console/health/**,/actuator/**,/v1/console/server/**

### The auth system to use, currently only 'nacos' and 'ldap' is supported:
nacos.core.auth.system.type=nacos

### If turn on auth system:
nacos.core.auth.enabled=false

### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.
nacos.core.auth.caching.enabled=true

### Since 1.4.1, Turn on/off white auth for user-agent: nacos-server, only for upgrade from old version.
nacos.core.auth.enable.userAgentAuthWhite=false
nacos.core.auth.server.identity.key=serverIdentity
nacos.core.auth.server.identity.value=security
nacos.core.auth.plugin.nacos.token.expire.seconds=18000
nacos.core.auth.plugin.nacos.token.secret.key=SecretKey012345678901234567890123456789012345678901234567890123456789

#*************** Istio Related Configurations ***************#
### If turn on the MCP server:
nacos.istio.mcp.server.enabled=false

4、修改 Nacos.java 类

添加类配置类：ConfigConstants

package com.alibaba.nacos.console.config;

public interface ConfigConstants {

	/**
	 * The System property name of Standalone mode
	 */
	String STANDALONE_MODE = "nacos.standalone";

	/**
	 * 是否开启认证
	 */
	String AUTH_ENABLED = "nacos.core.auth.enabled";

	/**
	 * 日志目录
	 */
	String LOG_BASEDIR = "server.tomcat.basedir";

	/**
	 * access_log日志开关
	 */
	String LOG_ENABLED = "server.tomcat.accesslog.enabled";

}

主要在 main 方法中增加 两个参数，是否是单机启动 & 是否关闭权限校验

@SpringBootApplication(scanBasePackages = "com.alibaba.nacos")
@ServletComponentScan
@EnableScheduling
public class Nacos {

    public static void main(String[] args) {
        if (initEnv()) {
            SpringApplication.run(Nacos.class, args);
        }
    }

    /**
     * 初始化运行环境
     */
    private static boolean initEnv() {
        System.setProperty(ConfigConstants.STANDALONE_MODE, "true");
        System.setProperty(ConfigConstants.AUTH_ENABLED, "false");
        System.setProperty(ConfigConstants.LOG_BASEDIR, "logs");
        System.setProperty(ConfigConstants.LOG_ENABLED, "false");
        return true;
    }
}

5、修改 console/pom.xml

• 由于不在使用 nacos bom 管理，需要给所有依赖坐标增加版本号
• 由于 nacos-config /nacos-naming 等包没有上传至中央参考 无法下载到，groupId 变更为 com.pig4cloud.nacos 即可下载
• 变更后参考如下

总结

• 以上修改后源码参考： https://gitee.com/log4j/pig
• 是否以源码形式运行，此问题仁者见仁智者见智 根据你们实际情况来
