Setting up Reverse Proxy for MWS using Apache Server
Dec 18, 2020 14:21 0 Comments Server side NAIDU

Unlike IS, MFT, API gateway etc.. MWS does not have an out of the box enterprise gateway provided by SoftwareAG product suite. So, as per their product documentation, we need to go with other popular front-facing servers like Apache web server or Microsoft IIS to setup reverse proxy in DMZ. In this article, we will see how to do this using Apache web server.


  1. Get “gcc” installed using “sudo yum install gcc“. If gcc installation fails due to dependency on Kernel Headers, then get the kernel headers installed using “sudo yum install kernel-headers –disableexcludes=all
  2. Get “sudo yum install expat-devel” installed as Apache APR depends on this.
  3. Get “sudo yum install openssl-devel” installed as Apache HTTP Server SSL module depends on this.
  4. Download Apache HTTP server install-able from (httpd-NN.tar.gz)
  5. Download APR and APR-Util from (apr-NN.tar.gz and apr-util-NN.tar.gz)
  6. Download PCRE from (download pcre and not pcre2)
  7. Create three directories on the server where Apache has to be installed (This is DMZ server in our case residing on external domain).
    • /sag/apacheRIServer/apache  — In this location Apache will get installed
    • /sag/apacheRIServer/pcre  — In this location PCRE will get installed
    • /sag/ApacheInstallImg — In this location keep all the installation files that are downloaded as per #1 and #2.
    • Apache HTTP Server Installation:

      Extract the httpd-NN.tar.gz tar

      gzip -d httpd-NN.tar.gz
      tar xvf httpd-NN.tar

      Copy apr-NN.tar.gz and apr-util-NN.tar.gz to /sag/ApacheInstallImg//srclib/

      Change directory to /sag/ApacheInstallImg//srclib/

      Extract the tar files

      gzip -d apr-NN.tar.gz
      tar xvf apr-NN.tar
      gzip -d apr-util-NN.tar.gz
      tar xvf apr-util-NN.tar

      After extraction, DO NOT leave the directory names with version numbers. Rename the folders to “apr” and “apr-util” using mv command

      mv apr-1.6.3 apr
      mv apr-util-1.6.1 apr-util

      Now, Go inside “apr” folder and run below command

      ./configure --with-included-apr

      Extract the pcre-8.42.tar.gz tar

      gzip -d pcre-8.42.tar.gz
      tar xvf pcre-8.42.tar

      Install PCRE using below commands

      ./configure -prefix=/sag/apacheRIServer/pcre/ --disable-cpp
      make install

      Now, lets configure Apache HTTP server using below

      ./configure --prefix=/sag/apacheRIServer/apache --enable-so --enable-ssl --enable-proxy=shared --with-pcre=/sag/apacheRIServer/pcre --with-included-apr-util
      make install

      Change directory to /sag/apacheRIServer/apache/conf

      vi httpd.conf

      Go to the line where you see “Listen 80” and change it to listen to any port number you wish. I used 9090 below

      Listen 9090

      Now, go to the line where you see “#ServerName” and change it to below and save the file. The port number should be the same port that was configured in the previous step.


      Start the server to test if its working. Change directory to “/sag/apacheRIServer/apache/bin” and run below command to start the server

      ./apachectl -k start

      After few seconds, hit “:9090” and see if you get a page response showing “It Works!!” (as of apache version 2.4.33)

      If you see the message then you are good to move forward  Let’s see the SSL module now to enable server listening on HTTPs.

      Enable SSL module:

    • Create a directory under “/sag/apacheRIServer/apache/conf” and name it as “security“. This where we are planning to maintain all certificates required for SSL
    • Copy SSL certificates (.cer/.crt/.cert and .key files) to above folder (/sag/apacheRIServer/apache/conf/security)
    • Enable below directives in httpd.conf file. Uncomment them if entry is already present in file or make a new entry if not present
