Recently I went through installation process of Bareos on openSUSE. Bareos seems to be interesting solution for backups in heterogeneous  environments.

Ok,let’s start and see how to deploy in 5 steps:

• Step 1: Add repository with Beros and Beros WebUI; Install Beros
• Step 2: Create Bareos database and Tables on MySQL
• Step 3: Configuring Bareos (few config files)
• Step 4: Starting services and accessing WebUI portal
• Step 5: Enable/Autostart Bareos services (optional)

In case you want to deploy MediaWiki 1.25.1 with VisualEditor use following components:

• MediaWiki 1.25.1 http://releases.wikimedia.org/mediawiki/1.25/mediawiki-1.25.1.tar.gz – stable
• VisualEditor REL1_25 http://extdist.wmflabs.org/dist/extensions/VisualEditor-REL1_25-c1ed854.tar.gz – stable
• UniversalLanguageSelector REL1_25 http://extdist.wmflabs.org/dist/extensions/UniversalLanguageSelector-REL1_25-7661826.tar.gz – stable

Configuration details for LocalSettings.php for these components can be found here:

• http://www.mediawiki.org/wiki/Extension:VisualEditor
• http://www.mediawiki.org/wiki/Extension:UniversalLanguageSelector

When you download VisualEditor from Git repository installation with MediaWiki 1.25.1 is more likely to fail.

I just found vi reference from Santa Cruz Operation (SCO) 🙂 Nice piece of memorabilia as well as handy reference for vi beginners.

If you use CentOS and want to add some extra packages you can use EPEL.

Extra Packages for Enterprise Linux is project created by Fedora.

In order to use repositories on CentOS first download and install RPM appropriate for your version of CentOS from here:

Method 1

http://dl.fedoraproject.org/pub/epel/

• epel-release-latest-5.noarch.rpm – CentOS 5.x
• epel-release-latest-6.noarch.rpm – CentOS 6.x
• epel-release-latest-7.noarch.rpm – CentOS 7.x

Then install it and enjoy more packages from new repo.

Method 2

[root@localhost ~]# yum install epel-release

Here is example from CenOS 7 how to add EPEL repositories:

Current expectations from all type of systems and services is to be available without any disruption. One of mission critical systems is gateway/firewall. Of course you can use multiple products available on the market. One of them is openSUSE, which is perfect to act as gateway/firewall between Internet and production systems. So, how to provide redundancy for openSUSE and same time be able to keep it up-to-date without any disruption for production systems?

openSUSE 13.2 with keepalived provides all technology required to make your firewall high-available.

Here is diagram of Lab created to configure and test openSUSE with keepalived:
