Here is the minimum configuration to enable SSL

Load the module and configure the certificate

Pre-requisites:

1. Disable your /etc/httpd/conf.d/ssl.conf by renaming it to ssl.conf.disabled (otherwise, Apache will take the properties from this file, and it can get quite confusing).
2. Open your firewall for https protocol
3. Get a certificate (Godaddy have the cheapest one, especially for wildcard ones)

CSR-Generation Instructions

To generate a triple-DES encrypted key pair and a Certificate Signing Request (CSR):

Enter the following commands:

1. cd /usr/bin/ (/your path to openssl/)
   Enter a passphrase when prompted to.
2. openssl genrsa -des3 -out <name of your certificate>.key 1024
3. openssl req -new -key <name of your certificate>.key -out <name of your certificate>.csr

If you are requesting a Wildcard certificate, please add an asterisk (*) on the left side of the Common Name (e.g., “*.domainnamegoes.com” or “www*.domainnamegoeshere.com”). This will secure all subdomains of the Common Name.

(source: Godaddy’s help)

BTW, Godaddy has the cheapest certificates you can find (with great support).

Make sure you have the EPEL Repository installed in your yum repository, do the following:

Install Git with

> yum install git

You should get something like:

Make sure the git package comes from EPEL and not RPMForge. If it comes from RPMForge, then, install yum-priorities:

> yum install priorities

Make sure that yum-priorities is enabled by editing the /etc/yum/pluginconf.d/priorities.conf file, and ensuring that it contains the following lines:

[main]
enabled=1

Add a priority=3 line in the /etc/yum.repos.d/rpmforge.repo
Add a priority=1 lines in each of the three repo sections in the /etc/yum.repos.d/elrepo.repo

Then, do the “yum install git”

Steps:

1. Download OpenOffice (Linux RPM)
2. Copy the .gz file to /tmp/
3. Unpack: tar -zxvf OOo_3.0.0_LinuxX86-64_install_en-US.tar.gz
4. Check if you have already an OpenOffice installed
   > rpm -qa | grep office
   openoffice.org-writer-2.0.4-5.4.17.1
   openoffice.org-core-2.0.4-5.4.17.1
   openoffice.org-calc-2.0.4-5.4.17.1
   openoffice.org-draw-2.0.4-5.4.17.1
   openoffice.org-impress-2.0.4-5.4.17.1
   openoffice.org-math-2.0.4-5.4.17.1
   openoffice.org-xsltfilter-2.0.4-5.4.17.1
   openoffice.org-graphicfilter-2.0.4-5.4.17.1
5. If yes, uninstall all rpms with:
   rpm -e openoffice.org-writer-2.0.4-5.4.17.1
   rpm -e openoffice.org-calc-2.0.4-5.4.17.1
   rpm -e openoffice.org-draw-2.0.4-5.4.17.1
   rpm -e openoffice.org-impress-2.0.4-5.4.17.1
   rpm -e openoffice.org-math-2.0.4-5.4.17.1
   rpm -e openoffice.org-xsltfilter-2.0.4-5.4.17.1
   rpm -e openoffice.org-graphicfilter-2.0.4-5.4.17.1
   rpm -e openoffice.org-core-2.0.4-5.4.17.1

   Note: remove the ..-core.. last

6. go to the RPMS/
   cd /tmp/OOO300_m9_native_packed-1_en-US.9358/RPMS/
7. Install all RPMs (in the /opt/ directory
   > rpm -ivh *.rpm

   or in a specific directory

   > rpm -ivh –prefix /mycoolerdir/ *.rpm
8. You should see something like: (probably in bigger font)
