Installing Plone 4 on Centos 6

Plone 4 is based on Python and Zope and provides its own little database.

Installation on Centos 6.3 was pretty straight forward in the standalone mode. Alternative, mode is as ZEO Cluster or a single running instance.

Step 1: Download the Unified installer (comes with Python and Zope) for Plone.

Download from ( with a file size of approx 50MB.


Step 2: Install dependency files.
Most of these are already installed if Centos was installed with the development tools.
Add the RPMForge repo;

rpm -ivh rpmforge-release-0.5.2-2.el6.rf.i686.rpm

yum install gcc gcc-g++ make tar bzip2 gzip
yum install readline libgsf
yum install wv

If there is problem with the wv package, download wv from EPEL or and install with RPM.

rpm -ivh wv-1.2.7-2.el6.i686.rpm

Step 3: Extract & Install Plone
Enter the directory with the UnifiedInstaller (Download directory).

tar zxvf Plone-4.2.1-UnifiedInstaller.tar.gz
cd plone-4.2.1
./ standalone
cd /usr/local/Plone/zinstance

Identify which port (default 8080) will be used for Plone. If needed, change the port then apply changes by typing


Step 4: Start/Stop Plone
The Plone server can be started or stop with following command (replace the word start)

/usr/local/Plone/zinstance/bin/plonectl start

Step 5: Access Plone
Open a web browser (e.g. Firefox, Chrome) and enter following URL address;


Default password is found in the file /usr/local/Plone/zinstance/adminPassword.txt

Create a Plone instance, then read the instructions at the main page of the Plone instance.

Additional notes:
Install following packages;

  • or libreoffice (headless) for better document conversion
  • msttcorefonts for better formatting compatibility, see previous post

Howto install Alfresco 4, the Community edition on Centos 6

Alfresco provides some very interesting functions. This includes support for networking with CIFS, WebDav and IMAP.


Check following have been done.
  1. Linux must be 64bit. Why? they only provided Alfresco for Linux on 64 bits, thats why.
  2. Install LibreOffice (yum install libreoffice libreoffice-headless), version was installed
  3. Install MySQL (yum install mysql-server), in my case version 5.1.61 was installed.

Following are steps that I have taken to install Alfresco 4 on Centos 6.

Step 1. Create the database
At the CLI, login to MySQL and create database named "alfresco"

# mysql -u root -p

Step 2. Start LibreOffice as headless

soffice "-accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager" \
 -nologo -headless

Step 3. Get the software and install

Download from
Double click on the file alfresco-community....bin and follow the onscreen instructions.

I choose the "Easy" method, and included the "Share"

Alternatively, installation can be done at the Linux CLI, just switch to root user, go to the directory where the file was downloaded and type
# ./alfresco-community-4.0.x-installer-linux-x64.bin ---mode text

Step 4. Start Alfresco, based on the Tomcat server port of 8080.
Alfresco started automatically, but is needed, got the the /opt/alfresco folder and type start

Access the application with a web browser and the following URLs/

and http://localhost:8080/share
