使用nginx反向代理出现jenkins出现404错误

Question

nginx配置：

server {

    listen 80;
    server_name localhost;

    location /jenkins {

      proxy_set_header        Host $host:$server_port;
      proxy_set_header        X-Real-IP $remote_addr;
      proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header        X-Forwarded-Proto $scheme;

      # Fix the "It appears that your reverse proxy set up is broken" error.
      proxy_pass          http://127.0.0.1:8081;
      proxy_read_timeout  90;
    }
  }

使用浏览器访问http://ip/jenkins，会跳转到http://ip/login?from=%2Fjenkins，出现404错误。

但使用下面的nginx配置

server {

    listen 80;
    server_name localhost;

    location / {

      proxy_set_header        Host $host:$server_port;
      proxy_set_header        X-Real-IP $remote_addr;
      proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header        X-Forwarded-Proto $scheme;

      # Fix the "It appears that your reverse proxy set up is broken" error.
      proxy_pass          http://127.0.0.1:8081;
      proxy_read_timeout  90;
    }
  }

使用浏览器访问http://ip，会跳转到http://ip/login?from=%2Fjenkins，但是能正常访问，这是为什么呢？

想实现http://ip/jenkins这种访问方式，要怎样配置nginx？

大概是这样

server{
    location / {
        try_files $uri @jenkins;
     }
     
    location @jenkins {
        internal;
        proxy_pass http://127.0.0.1:8080;
    }
}
