SonarQube返回错误的网关错误

Question

我正在尝试使用Caddy为SonarQube服务。我能够查看该网站，但它返回502 Bad Gateway。该服务似乎已启动并正在运行。当地卷曲也被拒绝。

卷曲

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

#sonar.web.javaOpts=-Xmx512m -Xms128m -XX:+HeapDumpOnOutOfMemoryError

# Same as previous property, but allows to not repeat all other settings like -Xmx

# Binding IP address. For servers with more than one IP address, this property specifies which
# address will be used for listening on the specified ports.
# By default, ports will be used on all IP addresses associated with the server.

# Web context. When set, it must start with forward slash (for example /sonarqube).
# The default value is root context (empty value).

Caddyfile

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不是可路由的地址。它被服务器用作"meta-address"来指定它应该监听所有可用的地址而不是一个。因此，服务器可以倾听 0.0.0.0，但客户无法向 0.0.0.0发出请求。您的Caddy文件应如下所示：

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
