Other Technical Documentation

Both Anaconda and CentOS systems use a common set of software components. For detailed information on key technologies, see the web sites listed below.

Boot Loader: CentOS uses the GRUB2 boot loader. See the corresponding chapter in the RRed Hat Enterprise Linux 7 System Administrator’s Guide.
Storage Management: Logical Volume Management (LVM) provides administrators with a range of facilities to manage storage. By default, the CentOS installation process formats drives as LVM volumes. For further details about LVM, see the Red Hat Enterprise Linux 7 Logical Volume Manager Administration Guide.
Remote Displays: CentOS and Anaconda include VNC (Virtual Network Computing) software to enable remote access to graphical displays. For more information about VNC, see the TigerVNC chapter in the Red Hat Enterprise Linux 7 System Administrator’s Guide.
Remote System Access: CentOS incorporates the OpenSSH suite to provide remote access to the system. The SSH service enables a number of functions, which include access to the command-line from other systems, remote command execution, and network file transfers. During the installation process, Anaconda might use the scp feature of OpenSSH to transfer crash reports to remote systems. For further details about OpenSSH, see the corresponding section in the Red Hat Enterprise Linux 7 System Administrator’s Guide.
Access Control: SELinux provides Mandatory Access Control (MAC) capabilities that supplement the standard Linux security features. See the Red Hat Enterprise Linux 7 SELinux User’s and Administrator’s Guide for further information.
Firewall: CentOS uses firewalld to provide firewall features. For further information, see the corresponding chapter in the Red Hat Enterprise Linux 7 SELinux User’s and Administrator’s Guide.
Software Installation: CentOS uses yum to manage the RPM packages that make up the system. See the corresponding chapter in the Red Hat Enterprise Linux 7 Administrator’s Guide for further information.
Virtualization: Virtualization provides the capability to simultaneously run multiple operating systems on the same computer. CentOS also includes tools to install and manage the secondary systems on a CentOS host. You can select virtualization support during the installation process, or at any time thereafter. See the Red Hat Enterprise Linux 7 Virtualization Deployment and Administration Guide for more information.
