Use the following steps to install PCC in a Linux headless environment:

Required Action

The '#' sign in command examples denotes running the command as the root user. All command lines preceded by the '>' sign are the example output of that command, where applicable.

Step 1 - Download Prizm Content Connect (PCC)

Before you download PCC, note that packages are only available for 64-bit systems.

Before downloading PCC, you will need to purchase a license key or request a Trial Evaluation by filling out the following form: www.accusoft.com/products/prizm-content-connect-pcc/get-self-hosted/.

Once you have purchased a license key or filled out the form for a Trial Evaluation, you can download PCC by:

  1. Following the link provided in the response email and selecting the desired Linux Distribution.

OR

  1. Downloading directly to the Linux server using the 'wget' command for the specific distribution as shown below:

Red Hat, Fedora, CentOS, and Older Linux Distributions

Example
Copy Code 
wget http://products.accusoft.com/PCC/<version>/prizmcc_<version>.x86_64.rpm.tar.gz

Debian and Ubuntu Linux Distributions

Example
Copy Code 
wget http://products.accusoft.com/PCC/<version>/prizmcc_<version>.amd64.deb.tar.gz

Generic .tar.gz Distribution

Example
Copy Code 
wget http://products.accusoft.com/PCC/<version>/prizmcc_<version>.x86_64.tar.gz

For license, fill out the form at http://www.accusoft.com/products/prizm-content-connect-pcc/get-self-hosted/ or http://www.accusoft.com/contact/. 

Step 2 - Unpack & Install the Downloaded Archive

Open a command line and change to the location where you downloaded the tarball. Use the following command line examples appropriate for your distribution to:

  1. Decompress and unpack the downloaded file. After you have unpacked the archive, the contents will have been decompressed into a directory named "prizmcc_<version>_rpm(or _deb)". 
  2. Change to the unpacked directory and install the packages.

Red Hat, Fedora, CentOS, and Older Linux Distributions

The following example is for Red Hat, Fedora, CentOS, and older Linux distributions:

Example
Copy Code 
# tar –xzvf prizmcc_<version>_rpm.tar.gz
 # cd prizmcc_<version>_rpm
 # yum install –nogpgcheck *.rpm

Note: For CentOS 5.x, the following additional dependencies must be installed prior to PCC RPM installation:

  • openjpeg-libs-1.3-7.el5.x86_64.rpm
  • pixman-0.22.0-2.2.el5_10.x86_64.rpm

The Prizm installer does not install them automatically. Please download and install them manually using --nogpgcheck flag as follows:

Example
Copy Code 
# yum install --nogpgcheck ./openjpeg-libs-1.3-7.el5.x86_64.rpm
# yum install --nogpgcheck ./pixman-0.22.0-2.2.el5_10.x86_64.rpm

Debian (Ubuntu) Linux Distributions

The following example is for Debian (Ubuntu) Linux distributions:

Example
Copy Code 
# tar –xzvf prizmcc_<version>_deb.tar.gz
 # cd prizmcc_<version>_deb
 # sudo dpkg –i *.deb
 # sudo apt-get –f install

Generic .tar.gz Distribution

We also provide a generic .tar.gz package. You will need to install the dependencies described in the Requirements section. Once the dependencies are installed, you can install the .tar.gz with the following commands as root:

Example
Copy Code 
# tar -xzvf prizm-contentconnect*.tar.gz
 # tar -xzvf prizm-services*.tar.gz
 # cp -R prizm /usr/share/

 

Step 3 - Setup

  1. Run the following commands to initiate setup:
Example
Copy Code 
# cd /usr/share/prizm
# sh ./setup.sh

The setup script will now invoke a text-based wizard for licensing:

To install a license at the end of the evaluation period, (for example, a deployment license), run the following command:

Example
Copy Code 
# ./setup.sh eval get youremail@example.com
If you already have a license for PCC, you can use one of the other licensing options, detailed in the Command Line Mode Licensing section of the help.
  1.  To confirm the licensing has succeeded, run the following command, which will output your license key:   
Example
Copy Code 
# cat ./conf/proxyserver_jar.properties | grep license_key
> license_key=<long string>
       
  1. If PCC has started and no errors have been reported, then the installation process is complete.
However, if you have an error in the log stating that it cannot connect to the Office converter Worker-1 instance, then you must continue to the 'Step 4 - Running an X Virtual Framebuffer' section below.

 

Step 4 - Running an X Virtual Framebuffer Server

A full version of the X11 server is not required to run PCC. However, the minimum requirement is the X Virtual Framebuffer Server, which you can install and run separately from an entire X11 instance.

  1. To install the X Virtual Framebuffer Server, run the following command:

Debian/Ubuntu

Example
Copy Code 
# sudo apt-get install xvfb
   

Red Hat / CentOS

Example
Copy Code 
# yum install xorg-x11-server-Xvfb
  1. Start the service by running the following command, and then export the instance to the DISPLAY environment variable expected by the Prizm service:
Example
Copy Code 
# Xvfb :20 >/dev/null 2>&1 &
# export DISPLAY=:20

  1. Start PCC:
Example
Copy Code 
# /usr/share/prizm/scripts/pccis.sh start

Required:

The X Virtual Framebuffer Server must be running any time that the Prizm service is running.

Suggested:

It may be appropriate to create a script that will start the Xvfb service and Prizm Services (the 3 lines above) to execute whenever the machine is restarted.

 

Step 5 - Configure on CentOS 5.x (Optional)

If you aren't running CentOS 5.x, you can skip to Step 6 below.

PCC will not work on a CentOS 5.x system with the default LibreOffice. For this purpose you need to download and install LibreOffice from libreoffice.org as described below:

  1. Install the latest stable version of LibreOffice for your OS. Download and install it from this location: www.libreoffice.org/download
  2. Follow LibreOffice Installation instructions from this location: www.libreoffice.org/get-help/documentation/

LibreOffice Desktop Integration for Linux is not needed; you do not need to complete those steps.

The LibreOffice installation might fail if you have LibreOffice or any other application already listening on any of the following ports: 18580, 18584, 18585, 18586, 18590, 18591, 18592, 18593, 18680.

By default, Prizm Content Connect installs the proxy service on port 18680 and uses 3 of the following ports for conversion purposes: 18580, 18584, 18585, 18586, 18591, 18592, 18593. You can add more ports as your traffic increases.
  1. Locate root folder of your LibreOffice installation. The LibreOffice is usually located in the following directory: /opt/libreoffice4.x
  1. Edit <prizm-install>/conf/proxyserver_jar.properties and change following parameter to fit the root location of LibreOffice:
Example
Copy Code 
Office Document converter installation base directory
#odc_installation=/usr/share/prizm/libreoffice
odc_installation=/opt/libreoffice4.3
  1. Change the watchdog.config OCS officeInstallPath to point to a community version of LibreOffice:

By default this value is:

Example CS
Copy Code
"officeInstallPath":"../libreoffice/program"

or

Example
Copy Code 
"officeInstallPath":"/usr/share/prizm/libreoffice/program"

Example of fixed path:

Example
Copy Code 
"officeInstallPath":"/opt/libreoffice4.4/program"
  1. Save proxyserver_jar.properties, restart Prizm service and check proxyserver.log to make sure PCC uses the installed LibreOffice.

Step 6 - Verify that the Installation was Successful   

  1. Browse to the following either via URL or through browser http://localhost:18681/admin:
 
It may take several minutes for the Services to become completely healthy. The page will auto-refresh as the Services come online.
  1. Your installation is now complete.

 

Enabling Upload of Larger Files Through nginx on Linux

By default /usr/share/prizm/nginx/nginx.conf contains the following limitation:

/usr/share/prizm/nginx/nginx.conf
http {client_max_body_size 100m; ... }

which limits maximum document file size to 100Mb, and so nginx will return HTTP-500 when larger files are uploaded to the service.

If you are dealing with larger files it will necessary to change "client_max_body_size" option to a more appropriate value.
