It is possible to run E.F.A. on a VPS that only grants you the option to do a bare installation of CentOS.

Note that this is only for experienced users and should be avoided for normal usage unless you really have to.

**Warning: Building E.F.A. should only be done by users with extensive Linux knowledge.**


===== Requirements =====

You will need the following requirements:
  * Centos 6 x64 minimal installation pre-installed
    * If you have the option partition the disk as:
      * 512MB EXT3 /boot
      * LVM Physical volume for the rest (call it vg_00):
        * 8GB /     (call it lv_root)
        * 10GB /tmp  (call it lv_tmp)
        * 4GB SWAP  (call it lv_swap)
        * xxGB /var (call it lv_var) (the reset of your disk space)
  * Atleast 30GB of harddrive space
  * 4GB memory
  * Active internet connection (About 0.5 ~ 1GB will be downloaded, depending on the needed updates.)
  * Root access
  * Free access over the internet (minimum is http/https access)
  * A bunch of free time

===== Start building =====
  - Make sure you have root access to the system and login as the root user (or su - root)
  - Make sure the system is fully updated: 
    - ''yum -y update''
  - Install wget & screen:
    - ''yum -y install wget screen''
  - Get the installation script:
    - ''wget https://raw.githubusercontent.com/E-F-A/v3/master/build/prepare-build-without-ks.bash''
  - Make the script executable:
    - ''chmod 700 prepare-build-without-ks.bash''
  - Start a screen session:
    - ''screen''
  - Start the installation:
    - ''./prepare-build-without-ks.bash''
  - The system is now installed, depending on the speed of your internet connection and the speed of the system this can take a while, so sit back and let it run.

==== After building ====
After building the system you will need to follow the normal [[initial_configuration|Initial Configuration]].
