Hi mate, there are many ways to deploy the Apache web server application in Linux. But in this Article, i’ll guide you, the best way to deploy it for Content server/ Document management system.  Also will share the idea on sap content server application installation & further back end sap systems configuration in detail.

Agenda :

  • Fulfill the Hardware prerequisites.
  • RPM packages installation
  • Apache dependency libraries deployment
  • Apache Web Server installation
  • Content_server installation.
  • Content-server Running status
  • SAP Back end systems configuration
  • Content/Apache server start & stop procedures

Prerequisites for Apache:

  • For Content Server in Unix, pre-installed Apache(≤2.2.9) web server must & should be available.
  • For Apache installation, the below things should be available.
    • Required environmental variables should be set as per Hardware & follow the sap note 664384
    • Also required RPM packages should be installed
    • ANSI C or GNU compiler
    • Also need to be configured, required dependency libraries. But these libraries are available by default up to the version 2.2.9.
      • Apr
      • Apr-util
      • Pcre
  • Required scripts :
    • ./configure
    • make
    • make install

Step by step Apache Web Server :

  • First of all, we need to create the required user like ‘sapcs’ with home directory as ‘/usr/users/sapcs’ or ‘/home/sapcs’. Do not provide the admin rights to prevent unnecessary installations. But don’t use the default directory : ‘/usr/local/’.
  • Assign the user to sapsys & sapinst groups.
  • If your are trying to install the Cache server as well, then create another user like ‘sapcsc’ with different home directory like ‘/home/sapcsc’.
  •  Now set the required environmental variable as per the note 664384 in your Unix Hardware. Also make sure that required RPM packages available.
  • Now move the downloaded Apache Httpd  zip file to respective user home directory. You can unzip files by using below commands.
    • gunzip -c httpd-2.4.35.tar.bz2 | tar xvf –
  • Make sure that, you have to install the web server separately for both Content & Cache server.
  • You can deploy the Apache server with below configuration script.
    • ./configure –prefix=/usr/users/sapcs –enable-modshared=MODULE-LIST=most -with-mpm=MPM=prefork -eith-expat=builtin –with-included-apr
    • make
    • make install
  • Install content server with the web server home directory as /usr/users/sapcs as  like below steps.

Step by Step Content server installation :

  • Run the Software Provision Manager (SWPM) by using command  ./sapinst.
  • Then select the Content Server for installation in generic options.
    apache
  • Select the Content or Cache Server as per requirement.
  • Then provide Label.asc file of software packages.
    apache
  • Now provide the Apache server home directory as a Content web server root.
    Apache
  • Then provide the content server repository root directory. Here, by default it is available with Apache home directory.  If required, you can change it.
    Apache
  • Finally review the all selected parameters again & complete the installation.

Content-Server Running status :

  • Once installation completed, restart the Apache-server as explained in the next steps.
  • If it is working fine, then the running status will show you in the below URL.
    http://<host name>:1090/ContentServer/ContentServer.dll?serverinfo

Back end ABAP System Configuration :

  • Before doing to configuration, make sure that CS port 1090 is listening in your SAP ABAP server. Also do the Host entries in /etc/host file.
  • Then create a repository object like ZDMS_C1 for respective abap_system in OAC0 transaction. Provide all below inputs for the same.
    • Content Rep.  : ZDMS_C1
    • Description     : SAP_Content_Server
    • Storage type    : 04 HTTP Content Server
    • Version no.      : 0047
    • HTTP Server   : <CS Host Name>
    • Port Number   : 1090
    • HTTP Script    : /ContentServer/ContentServer.dll
  • After that go to ‘CSADMIN’ transaction. Then select settings tab & add the created object by providing the below CS server details
    • ContentStorageHost : <Host Name>
    • Security                       : 0
    • FullTrace                     : 0
    • ContRepRoot              : /SAP/ContRep
    • ContentSorageName : SAP
    • Storage                         : FileSystemStorage.dll
    • ContRepDescription : SAP Content Server
  • Once provided the above details, execute it. Then automatically added with green light & running status.
  • Then cross verify by adding an attachment in the below transactions from “Service for object’. Which is available at left top corner of the screen.
    ME21n/ME22n/ME23n/ME51n/ME52n/ME53n
  • That’s it.

To Start/Stop Apache – Content Server :

  • Here, to start or stop CS, just start or stop the Apache-Server only as like below.
  • First of all login to the dms server with root or <sid>adm user. Then go to sapcs user home directory. Then switch to /bin directory.
  • In that bin directory, your able to see ‘Apachectl'(.exe) file. By using that file, you can start/stop as per below commands.
    • ./apachectl start
    • ./apachectl stop
