By | September 30, 2018

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 :

  • Fulfil 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 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 Procedure :

  • 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 system 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 attachment in ME21n/ME22n/ME23n/ME51n/ME52n/ME53n from “Service for object’. Which is available at left top corner of the screen.
  • That’s it.

To Start/Stop 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 user. Then go to sapcs user home directory. Then go 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
