Installing Octopress on CentOS 6/RedHat/Scientific Linux

Official Octopress website have user-specific installation procedure prone to many errors due to 'rvm' and 'rbenv'. This is the mostly foolproof method to set-up Octopress correctly on Redhat based distros.

Run these as root:

# yum groupinstall 'Development Tools'
# yum install readline-devel zlib zlib-devel openssl openssl-devel libyaml git python-setuptools
# easy_install Pygments

Pygments is not necessary as it uses pygments.rb. (Thanks to @octopress)

Now, run these as normal user:

$ wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2-p320.zip
$ unzip ruby-1.9.2-p320.zip 
$ cd ruby-1.9.2-p320
$ ./configure --prefix=/usr --with-openssl-include=/usr/include/openssl --with-openssl-lib=/usr/lib64/openssl/engines --disable-option-checking --disable-pthread
$ make

If you are using 32-bit, then replace '--with-openssl-lib=/usr/lib64/openssl/engines' to '--with-openssl-lib=/usr/lib/openssl/engines'.

Again, run these as root:

# make install

Again, run these as normal user:

$ git clone git://github.com/imathis/octopress.git octopress
$ cd octopress

Now, as root:

# gem install bundler
# bundle install
# rake install

Lastly, as normal user:

$ rake install

Now, follow Configuring Octopress. That's it. You have installed Octopress on your system. Leak: I will soon be moving this blog to Octopress and will be hosting it on GAE.
