使用Nginx和Spring Gateway为SkyWalking的增加登录认证功能-Toy模板网

这篇具有很好参考价值的文章主要介绍了使用Nginx和Spring Gateway为SkyWalking的增加登录认证功能。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

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

skywalking 登录,java,nginx,spring,gateway

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
