CentOS 6<\/h1>\n

In this section, the GNOME desktop will be added to a new server running CentOS 6.2 (x86_64) after performing a “Minimal” install.<\/p>\n

Install Desktop Packages<\/h2>\n\n\n\n
\n

# yum -y groupinstall \"Desktop\" \"Desktop Platform\" \"X Window System\" \"Fonts\"<\/b><\/pre>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
You can also install the following optional GUI packages.<\/p>\n\n\n\n
\n

# yum -y groupinstall \"Graphical Administration Tools\"<\/b>\r\n\r\n# yum -y groupinstall \"General Purpose Desktop\"<\/b>\r\n\r\n# yum -y groupinstall \"Office Suite and Productivity\"<\/b>\r\n\r\n# yum -y groupinstall \"Graphics Creation Tools\"<\/b><\/pre>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Finally, if you wanted to add the K Desktop Environment (KDE).<\/p>\n\n\n\n
\n

# yum -y groupinstall kde-desktop<\/b><\/pre>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
When using\u00a0yum groupinstall<\/tt>, the\u00a0groupinstall<\/tt>\u00a0option only installs\u00a0default<\/i>\u00a0and\u00a0mandatory<\/i>\u00a0packages from the group. There are times when you also want to include\u00a0optional<\/i>\u00a0packages within a group. I have not figured out (yet) how to control which package types to install (group package “policy”) from the command-line using\u00a0yum<\/tt>. The only method I know of to also includeoptional<\/i>\u00a0packages is to edit the\u00a0\/etc\/yum.conf<\/tt>\u00a0file and add the following to the\u00a0[main]<\/tt>\u00a0section:<\/p>\n\n\n\n
\n

group_package_types=default mandatory optional<\/span><\/pre>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
The reason I mention this is because I wanted to install “Terminal emulator for the X Window System” (xterm<\/tt>) which is under the group “Legacy X Window System compatibility”.\u00a0xterm<\/tt>\u00a0happens to be an optional package and did not get installed until I addedgroup_package_types=default mandatory optional<\/tt>\u00a0to\u00a0\/etc\/yum.conf<\/tt>.<\/p>\n\n\n\n
\n

# yum -y groupinstall \"Legacy X Window System compatibility\"<\/b><\/pre>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
I did find a plug-in for\u00a0yum<\/tt>\u00a0that allows users to specify which package types within a package group should be installed when using\u00a0yum groupinstall<\/tt>.<\/p>\n

Enable GNOME<\/h2>\n
Since the server was previously running on CLI mode, we need to change the initialization process for the machine to boot up in GUI mode.<\/p>\n
Open\u00a0\/etc\/inittab<\/tt>\u00a0using a text editor and change following line:<\/p>\n\n\n\n
\n

id:3:initdefault:<\/pre>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
To:<\/p>\n\n\n\n
\n

id:5<\/span>:initdefault:<\/pre>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
After making the change, reboot the machine.<\/p>\n\n\n\n
\n

# init 6<\/b><\/pre>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Note that you can switch from GUI to CLI mode manually by using following method:<\/p>\n
\n
GUI to CLI<\/b>:\u00a0Ctrl + Alt + F6<\/tt>
CLI to GUI<\/b>:\u00a0Ctrl + Alt + F1<\/tt><\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"
