    My first time installing CentOS 7.0 so decided to install it on a local VirtualBox Guest server using the CentOS 7.0 x86_64 64bit ISO dvd.


    Will use this for my base test server for Centmin Mod testing just as I did with CentOS 5.x and 6.x :)

    Screenshots below.

    First part loading the CentOS 7.0 64bit ISO dvd file and starting the VirtualBox guest server

    Now to do Centmin Mod Nginx, PHP-FPM and MariaDB MySQL compatibility tests for CentOS 7.0 64bit. FYI, CentOS 7.0 64bit already defaults to MariaDB MySQL when installed, so will see what differences there are from CentOS 7 64bit installed MariaDB MySQL and MariaDB official YUM repository installs :)

    CentOS 7 and systemd replacing init.d (SysVinit) will take some time getting use to found a cheat sheet for Fedora's systemd wonder if it's exactly same as CentOS 7 https://fedoraproject.org/wiki/SysVinit_to_Systemd_Cheatsheet ?

    Code:
    systemctl is-active crond.service
    active
    CentOS 7 systemd replaces init.d start/stop system !

    MariaDB MySQL defaults out of the box is MariaDB 5.5.35 with 5.5.37 update available so maybe better to use MariaDB official YUM repo as we are doing with Centmin Mod as it's already at MariaDB 5.5.38 and soon MariaDB 10.0.x ? :)

    #  This is the default, if you make this bigger yum won't see if the metadata

    # information.
    #  It is esp. important, to have correct metadata, for distributions like
    # Fedora which don't keep old packages around. If you don't like this checking
