SkyWalking的可视化后台是没有用户认证功能的，默认下所有知道地址的用户都能访问，官网是建议通过网关增加认证。
本文介绍通过Nginx和Spring Gateway两种方式

1、使用Nginx增加认证。

生成密钥

yum install -y httpd-tools
htpasswd -cb nginx/htpasswd skywalking rtgdbhyffddu#

配置nginx

worker_processes 1;
error_log stderr notice;
events {worker_connections 1024;
}
http {variables_hash_max_size 1024;access_log off;#ireal_ip_header X-Real-IP;charset utf-8;server {listen 8081;#auth_basic "Please enter the user name and password"; #这里是验证时的提示信息#auth_basic_user_file /data/skywalking/nginx/htpasswd;index  index.html;location / {root   html;index  index.html index.htm;#auth_basic on;auth_basic "Please enter the user name and password"; #这里是验证时的提示信息auth_basic_user_file /etc/nginx/htpasswd;proxy_pass http://172.17.0.9:8080;# WebSocket 穿透#proxy_set_header Origin "";#proxy_set_header Upgrade $http_upgrade;#proxy_set_header Connection "upgrade";}}
}

密码配置：/etc/nginx/htpasswd

2、使用Spring Gateway增加认证

主要是使用Spring Gateway和Spring Security的基础认证formLogin实现，
pom.xml使用的依赖包

WebGatewayMain.java

package com.penngo.web.gateway;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class WebGatewayMain {public static void main(String[] args) {SpringApplication.run(WebGatewayMain.class, args);}
}

SecurityConfiguration.java配置

package com.penngo.web.gateway;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.core.userdetails.MapReactiveUserDetailsService;

import org.springframework.security.web.server.SecurityWebFilterChain;import static org.springframework.security.config.Customizer.withDefaults;@EnableWebFluxSecurity
@Configuration
public class SecurityConfiguration {@BeanSecurityWebFilterChain springWebFilterChain(ServerHttpSecurity http) {http.authorizeExchange((authorize) -> authorize.anyExchange().authenticated()).cors(cors->cors.disable()).csrf(csrf->csrf.disable()).formLogin(withDefaults());return http.build();}/*** 可以在代码中配置密码，也可以在application.xml中配置密码* @return*/
//    @Bean
//    MapReactiveUserDetailsService userDetailsService() {
//
//        UserDetails user = User.withDefaultPasswordEncoder()
//                .username("admin")
//                .password("123456")
//                .roles("USER")
//                .build();
//        return new MapReactiveUserDetailsService(user);
//    }
}
