linux - SonarQube 返回错误的网关错误

Question

我正在尝试使用 Caddy 为 SonarQube 提供服务。我能够查看该站点，但它返回 502 Bad Gateway。该服务似乎已启动并正在运行。本地 curl 也被拒绝。

curl

curl -I 0.0.0.0:9000
curl: (7) Failed to connect to 0.0.0.0 port 9000: Connection refused

#--------------------------------------------------------------------------------------------------
# WEB SERVER
# Web server is executed in a dedicated Java process. By default heap size is 512Mb.
# Use the following property to customize JVM options.
#    Recommendations:
#
#    The HotSpot Server VM is recommended. The property -server should be added if server mode
#    is not enabled by default on your environment:
#    http://docs.oracle.com/javase/8/docs/technotes/guides/vm/server-class.html
#
#    Startup can be long if entropy source is short of entropy. Adding
#    -Djava.security.egd=file:/dev/./urandom is an option to resolve the problem.
#    See https://wiki.apache.org/tomcat/HowTo/FasterStartUp#Entropy_Source

卡迪文件

https://....com {
  tls self_signed
  gzip
  proxy /  0.0.0.0:9000
}

http://....com {
  tls off
  gzip
  proxy / 127.0.0.1:9000
}

Answer 1

0.0.0.0 不是可路由地址。它被服务器用作 "meta-address"指定它应该监听所有可用地址，而不是只监听一个。因此，服务器可以监听 0.0.0.0，但客户端不能向 0.0.0.0 发出请求。你的 Caddyfile 应该是这样的:

https://....com {
  tls self_signed
  gzip
  proxy / 127.0.0.1:9000
}

http://....com {
  tls off
  gzip
  proxy / 127.0.0.1:9000
}

本地 cURL 请求应如下所示:curl 127.0.0.1:9000
