英文:
Two reverse proxies on the same domain, diferent path
问题
我正在尝试在同一台机器上配置两个不同的反向代理，使用不同的路径。它们被设置为代理 SonarQube（localhost:9000/sonar）和 Jenkins（localhost:8080/jenkins）。
我正在尝试实现这样的效果：访问 http://server.name/sonar 时，将代理到 http://localhost:9000/sonar。
我有两个问题：
-
Sonar 被正确代理，但在回调 URL（点击标志时）会指向 http://server.name，而不是 http://server.name/sonar。我已尝试使用 X-Forwarded-Host 标头（应该也包含在 ProxyPreserveHost 指令中）。
-
Jenkins 代理不起作用。它返回 404 错误。
我做错了什么？

I'm trying to configure two different reverse proxies on the same machine with diferent paths. They are set to proxy SonarQube (localhost:9000/sonar) and Jenkins (localhost:8080/jenkins).
I'm trying to achive that calling to http://server.name/sonar, proxifys to http://localhost:9000/sonar.
I have two issues:
- Sonar is correctly proxified but on the callback url (clicking in the logo), will point to http://server.name, instead http://server.name/sonar. I have tried with the X-Forwarded-Host header (which should be also included in ProxyPreserveHost directive).
- Jenkins proxy is not working. It crashes with a 404.
What I'm doing wrong?

ProxyPreserveHost On

问题出在您定义虚拟主机的方式上。ServerName 只能理解域名，而不能理解 /something。
选项1 定义域名前缀。
<VirtualHost *:80>
ServerName sonar.server.name
ProxyPass /sonar http://localhost:9000/sonar/
ProxyPassReverse /sonar http://localhost:9000/sonar/
ErrorLog logs/sonar/error.log
CustomLog logs/sonar/access.log common
</VirtualHost>
<VirtualHost *:80>
ServerName jenkins.server.name
ProxyPass /jenkins http://localhost:8080/jenkins/
ProxyPassReverse /jenkins http://localhost:8080/jenkins/
ErrorLog logs/jenkins/error.log
CustomLog logs/jenkins/access.log common
</VirtualHost>
然后，您需要使用 http://jenkins.server.name/jenkins/ 或 http://sonar.server.name/sonar/。
选项2 与选项1类似，但不再需要 /sonar 或 /jenkins。
<VirtualHost *:80>
ServerName sonar.server.name
ProxyPass / http://localhost:9000/sonar/
ProxyPassReverse / http://localhost:9000/sonar/
ErrorLog logs/sonar/error.log
CustomLog logs/sonar/access.log common
</VirtualHost>
<VirtualHost *:80>
ServerName jenkins.server.name
ProxyPass / http://localhost:8080/jenkins/
ProxyPassReverse / http://localhost:8080/jenkins/
ErrorLog logs/jenkins/error.log
CustomLog logs/jenkins/access.log common
</VirtualHost>
在这里，使用 http://jenkins.server.name/ 或 http://sonar.server.name/。
选项3 保留一个域名，没有前缀，并在 /something 上分割。
全部放在一个虚拟主机中，像这样：
<VirtualHost *:80>
ServerName server.name
ProxyPass /sonar http://localhost:9000/sonar/
ProxyPassReverse /sonar http://localhost:9000/sonar/
ProxyPass /jenkins http://localhost:8080/jenkins/
ProxyPassReverse /jenkins http://localhost:8080/jenkins/
ErrorLog logs/error.log
CustomLog logs/access.log common
</VirtualHost>
不幸的是，以这种方式做，您会失去单独的日志文件。CustomLog 只适用于全局服务器配置或虚拟主机内部。
使用 http://server.name/jenkins/ 或 http://server.name/sonar/。
最后确保加载 mod_proxy_html 模块以及其他代理模块。
英文:
The problem is in the way you define your Virtual Hosts. ServerName does not understand /something, only domain names.
Option 1 define domain prefixes.
<VirtualHost *:80>
ServerName sonar.server.name
ProxyPass /sonar http://localhost:9000/sonar/
ProxyPassReverse /sonar http://localhost:9000/sonar/
ErrorLog logs/sonar/error.log
CustomLog logs/sonar/access.log common
</VirtualHost>
<VirtualHost *:80>
ServerName jenkins.server.name
ProxyPass /jenkins http://localhost:8080/jenkins/
ProxyPassReverse /jenkins http://localhost:8080/jenkins/
ErrorLog logs/jenkins/error.log
CustomLog logs/jenkins/access.log common
</VirtualHost>
You would then have to use http://jenkins.server.name/jenkins/ or http://sonar.server.name/sonar/.
Option 2 like option 1, but without the /sonar or /jenkins which are not required anymore.
<VirtualHost *:80>
ServerName sonar.server.name
ProxyPass / http://localhost:9000/sonar/
ProxyPassReverse / http://localhost:9000/sonar/
ErrorLog logs/sonar/error.log
CustomLog logs/sonar/access.log common
</VirtualHost>
<VirtualHost *:80>
ServerName jenkins.server.name
ProxyPass / http://localhost:8080/jenkins/
ProxyPassReverse / http://localhost:8080/jenkins/
ErrorLog logs/jenkins/error.log
CustomLog logs/jenkins/access.log common
</VirtualHost>
Here, use http://jenkins.server.name/ or http://sonar.server.name/.
Option 3 Keep one domain, no prefix and split on the /something
All in one Virtual Host. Like this:
<VirtualHost *:80>
ServerName server.name
ProxyPass /sonar http://localhost:9000/sonar/
ProxyPassReverse /sonar http://localhost:9000/sonar/
ProxyPass /jenkins http://localhost:8080/jenkins/
ProxyPassReverse /jenkins http://localhost:8080/jenkins/
ErrorLog logs/error.log
CustomLog logs/access.log common
</VirtualHost>
Sadly doing it this way you loose the separate log files. CustomLog is only applicable in the global server configuration or inside a VirtualHost.
Use http://server.name/jenkins/ or http://server.name/sonar/.
Finally ensure you load module mod_proxy_html along with the other proxy modules.
