Nginx location /logs 没有代理传递正确到导致 404 的 Kibana
Nginx location /logs doesn't proxy pass correctly to Kibana leading to 404
我们有一个 docker 化的架构。唯一和主要的入口点是我们的 nginx。这使得我们所有服务之间的 link。
访问位置为 /
的域名工作正常。我们的 Angular 前端应用显示正确。
主要问题是在 /logs
位置访问 KIBANA (v5.5)。
例如,尝试访问 https://dev.example.com/logs/
浏览器会显示 404,因为它尝试访问 https://dev.example.com/login?next=%2Flogs。
Kibana 似乎在我们的 Location 端点中代理,试图用 /
的基数 url 重写 url。而不是重写附加在 /logs/ location 之后的 URI。
如何改进我们的配置以:
- 允许访问 /logs/ 以正确显示我们的 Kibana 应用程序?
这是我们的 nginx 配置。请注意客户端、后端、kibana 指的是 docker 主机名。

感谢您对此的帮助。
您需要通过将 SERVER_BASEPATH
环境变量传递给 kibana 容器来将 server.basePath
设置为 /logs
。
然后,您需要在代理位置使用重写来去除 nginx 中的 /logs 前缀:
location /logs {
rewrite ^/logs(/.*)$ break;
proxy_pass http://kibana:5601;
proxy_set_header Host $host;
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 $scheme;
}
此外,kibana 中显然存在一个错误,只有当我们使用以下 url:
到达 kibana 时,以上配置才有效
http://nginxip/logs/
但如果我们没有结束斜线,则不会,例如:
http://nginxip/logs
为了解决这个问题,我们需要在 nginx 中添加另一个重写以确保总是有一个结束斜杠。在 /logs 位置之外添加以下内容:
rewrite ^/logs$ /logs/;
