Apache as a proxy for Nexus, Jenkins and Foreman (Several VirtualHosts on same domain, IP and Port)

I'd like to configure Apache to be used as a proxy for Nexus, Jenkins and Foreman which are installed and running on the same server.

Here is an example of the Virtual host config file for Foreman, the others files for Nexus and Jenkins looks pretty the same except the proxy pass parameters.

LoadModule ssl_module modules/mod_ssl.so
NameVirtualHost *:443
<VirtualHost *:443>
  SSLEngine On
  SSLProxyEngine On
  SSLCertificateFile /etc/httpd/ssl/certs/ssl.crt
  SSLCertificateKeyFile /etc/httpd/ssl/keys/server.key

  ServerName management.domain.com

  <Proxy *>
     Order deny,allow
     Allow from all
  </Proxy>

  ProxyPass        /foreman http://127.0.0.1:3000/foreman
  ProxyPassReverse /foreman http://127.0.0.1:3000/foreman
  ProxyPassReverse /foreman http://management.domain.com/foreman

  ProxyRequests Off
  ProxyPreserveHost On

  ErrorLog /var/log/httpd/management.domain.com_foreman_error.log
  LogLevel warn
  CustomLog /var/log/httpd/management.domain.com_foreman_access.log combined
</VirtualHost>

The problem is that Apache takes in account only one config file and ignores the two others which leads to the error message "The requested URL /jenkins/ was not found on this server." when I try to access the URL management.domain.com/jenkins

How to configure Apache to load the three virtual hosts ? Thanks

PS: the Listen directive is declared in httpd.conf (= 443)

If you use one servername it wouldn't work as you want. All you need is to merge 3 virt host in to the one. Something like

LoadModule ssl_module modules/mod_ssl.so
NameVirtualHost *:443
<VirtualHost *:443>
  SSLEngine On
  SSLProxyEngine On
  SSLCertificateFile /etc/httpd/ssl/certs/ssl.crt
  SSLCertificateKeyFile /etc/httpd/ssl/keys/server.key

  ProxyRequests Off
  ProxyPreserveHost On

  ServerName management.domain.com

  <Proxy *>
     Order deny,allow
     Allow from all
  </Proxy>

  ProxyPass        /foreman http://127.0.0.1:3000/foreman
  ProxyPassReverse /foreman http://127.0.0.1:3000/foreman
  ProxyPassReverse /foreman http://management.domain.com/foreman

  ProxyPass        /nexus http://127.0.0.1:3000/nexus
  ProxyPassReverse /nexus http://127.0.0.1:3000/nexus
  ProxyPassReverse /nexus http://management.domain.com/nexus

  ProxyPass        /jenkins http://127.0.0.1:3000/jenkins
  ProxyPassReverse /jenkins http://127.0.0.1:3000/jenkins
  ProxyPassReverse /jenkins http://management.domain.com/jenkins
