Como inverter portas específicas do proxy para um servidor diferente por trás de um firewall usando o Apache mod_proxy

1

Eu tenho dois servidores Web, um Apache 2 e o outro IIS 8, e ambos estão em uma LAN atrás de um firewall. Eu tenho portas 80, 443 e 8080-8088 abertas no firewall. Eu tenho um registro de DNS A hospedado externamente apontando para o meu firewall e regras de firewall que redirecionam essas portas para o servidor Apache. Eu também tenho uma entrada de DNS na rede local que aponta o registro para um endereço local de dentro do firewall. (por exemplo, fora do firewall, www.example.com aponta para 1.2.3.4, mas dentro do mesmo endereço aponta para 192.168.1.1). Eu quero que as portas 8080-8084 no servidor Apache sejam redirecionadas para o servidor IIS, e as portas restantes (80, 443, 8085-8088) sejam manipuladas pelo Apache normalmente. Todo o tráfego é HTTP (ou possivelmente HTTPS no futuro, se necessário), portanto, mesmo que os números das portas não sejam padronizados, todo o tráfego é normal.

Para o exemplo, vamos supor o seguinte:

  • Nome do host público: www.example.com
  • Endereço IP público: 1.2.3.4
  • Nome do host da LAN para o servidor Apache (em que www.example.com aponta): apache.example.local
  • Endereço IP do servidor Apache na LAN: 192.168.1.1
  • Nome do host da LAN para o servidor IIS (não acessível de fora da LAN): iis.example.local
  • endereço IP do servidor IIS na LAN: 192.168.1.2

Eu tentei configurar uma regra de proxy para cada um desses cenários:

  1. h ttp: //www.example.com/ aponta para o site padrão do Apache ( apache: 80 / ).
  2. h ttps: //www.example.com/ aponta para o site SSL do Apache ( apache: 443 / )
  3. h ttp : //www.example.com: 8080 / aponta para o site padrão do IIS ( iis: 80 / )
  4. h ttps : //www.example.com: 8080 / aponta para o site SSL do IIS ( iis: 443 / ) - Eu não consegui descobrir como fazer isso, então eu apontei para 8083 / , embora eu prefira que funcione como pretendido
  5. h ttp: //www.example.com: 8081 / wiki / aponta para o wiki do IIS ( iis: 8081 / w / ) - redireciona a porta e faz uma modificação de URL
  6. h ttp: //www.example.com: 8088 / aponta para um host virtual no Apache ( apache: 8088 / )

(Nota: " http " é mostrado como " h ttp " acima para evitar que o site pense que estou enviando este post com links.)

Aqui está o que eu criei graças à ajuda de outra pergunta e olhando para os documentos do VirtualHost Apache. Infelizmente, isso não funciona.

As portas 80 e 8088 funcionam corretamente. A porta 443 não pode completar a conexão segura (o que pode ser completamente não relacionado, então não vou me preocupar com isso agora). A porta 8080 apenas trava e o navegador eventualmente desiste. Portas 8081-8087 fazem a mesma coisa. Isso me leva a acreditar que o proxy não está funcionando corretamente.

Além de qualquer ajuda para que isso funcione, sinta-se à vontade para sugerir maneiras de torná-lo mais simples / mais curto / mais eficiente / mais seguro. Obrigado!

Substitui o código conceitual em minha postagem original por meu arquivo completo (semi-working) httpd.conf (e atualizei as notas acima para refletir a alteração):     #     # Este é o principal arquivo de configuração do servidor HTTP Apache. Ele contém o     # diretivas de configuração que fornecem ao servidor suas instruções.     # Veja http://httpd.apache.org/docs/2.4/> para informações detalhadas.     # Em particular, veja     # http://httpd.apache.org/docs/2.4/mod/directives.html>     # para uma discussão de cada diretiva de configuração.     #     # NÃO simplesmente leia as instruções aqui sem entender     # o que eles fazem. Eles estão aqui apenas como dicas ou lembretes. Se você não tiver certeza     # consultar os documentos on-line. Você foi avisado.
    #     # Configuração e nomes de arquivo de log: Se os nomes de arquivos que você especificar para muitos     # dos arquivos de controle do servidor começam com "/" (ou "drive: /" para Win32), o     # server usará esse caminho explícito. Se os nomes de arquivos não não começam     # com "/", o valor de ServerRoot é prefixado - então 'log / access_log'     # com ServerRoot definido como '/ www' será interpretado pelo     # server as '/ www / log / access_log', onde as '/ log / access_log' serão     # interpretado como '/ log / access_log'.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/etc/httpd"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
#Listen 80

#
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding 'LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by 'httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so
#
Include conf.modules.d/*.conf

#
# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.  
#
# User/Group: The name (or #number) of the user/group to run httpd as.
# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.
#
User apache
Group apache

# 'Main' server configuration
#
# The directives in this section set up the values used by the 'main'
# server, which responds to any requests that aren't handled by a
# <VirtualHost> definition.  These values also provide defaults for
# any <VirtualHost> containers you may define later in the file.
#
# All of these directives may appear inside <VirtualHost> containers,
# in which case these default settings will be overridden for the
# virtual host being defined.
#

#
# ServerAdmin: Your address, where problems with the server should be
# e-mailed.  This address appears on some server-generated pages, such
# as error documents.  e.g. [email protected]
#
ServerAdmin [email protected]

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
#ServerName www.example.com:80

    # Example:
    # Redirect permanent /foo http://www.example.com/bar

    #
    # Alias: Maps web paths into filesystem paths and is used to
    # access content that does not live under the DocumentRoot.
    # Example:
    # Alias /webpath /full/filesystem/path
    #
    # If you include a trailing / on /webpath then the server will

    #
    # AddHandler allows you to map certain file extensions to "handlers":
    # actions unrelated to filetype. These can be either built into the server
    # or added with the Action directive (see below)
