具有原始主机名的HA代理TCP余额

Question

我有一个带有3个节点的Splunk搜索头群集，并且我正在尝试设置一个HA代理实例以使用户登录到这3个搜索头节点之一中。

• Splunk 7.1
• HA代理1.5.18
• Centos 7

代理本身正在工作，并根据splunk运行状况（在端口8300上运行splunk）路由以更正SH节点

问题是，如果我转到“ splunk.company.local”（HA代理DNS名称），则HAproxy会将用户重定向到3个节点之一，但不会在URL中保留“ splunk.company.local” ，网址改为“ splunksh01.company.local”等，

我无法弄清楚如何使用单个粘性名称，因此用户始终位于“ splunk.company.com” URL下，并且从未看到实际的SH节点主机名，

haproxy.cfg

# This file managed by Puppet
global
  daemon  
  debug  true
  group  haproxy
  log  10.185.20.168 local0
  pidfile  /var/run/haproxy.pid

listen splunk
  bind 0.0.0.0:80 

  mode tcp
  balance source
  server splunksh01.company.local 10.185.20.173:80 check port 8300
  server splunksh02.company.local 10.185.20.174:80 check port 8300
  server splunksh03.company.local 10.185.20.176:80 check port 8300

现在在每个SH节点上，我都通过Apache反向代理运行Splunk，

cat /etc/httpd/conf.d/splunk.conf

<VirtualHost *:443>
  ServerName splunk

  ## Logging
  ErrorLog "/var/log/httpd/splunk-443_error_ssl.log"
  ServerSignature Off
  CustomLog "/var/log/httpd/splunk-443_access_ssl.log" combined 

  ## Request header rules
  ## as per http://httpd.apache.org/docs/2.2/mod/mod_headers.html#requestheader
  RequestHeader set X-Forwarded-Proto "https"

  ## Proxy rules
  ProxyRequests Off
  ProxyPreserveHost Off
  ProxyPass / https://splunksh01.company.local:8300/
  ProxyPassReverse / https://splunksh01.company.local:8300/

  ## SSL directives
  SSLEngine on
  SSLCertificateFile      "/etc/puppetlabs/puppet/ssl/certs/splunksh01.company.local.pem"
  SSLCertificateKeyFile   "/etc/puppetlabs/puppet/ssl/private_keys/splunksh01.company.local.pem"

  # SSL Proxy directives
  SSLProxyEngine On
</VirtualHost>

一旦HAproxy将请求路由到其中一个节点，如何保留相同的主机名？谢谢。
