RHEL7.x 기반 데스크탑 환경 구축 하기

작성일 : 2015년 12월 8일
작성자 : 서진우 (시스존)

1. RHEL7.x 설치

소프트웨어 구성에서 서버GUI 모드로 설치함.

2. NVIDIA Graphic Driver 설치

# vi /boot/grub2/grub.cfg
menuentry ‘Red Hat Enterprise Linux Server 7.1 (Maipo) …{

.
linux16 /boot/vmlinuz-3.10.0-229.el7.x86_64 root=UUID=0df416bd-ae66-4cc6-b1fa-2b4c2dd7c342 ro crashkernel=auto rhgb quiet LANG=ko_KR.UTF-8 rdblacklist=nouveau

;; 커널 옵션 마지막에 rdblacklist=nouveau 추가

# vi /etc/modprobe.d/nvidia-installer-disable-nouveau.conf
blacklist nouveau
options nouveau modeset=1

기본 부팅 runlevel 을 3 로 변경

# systemctl set-default multi-user.target

리부팅 후 NVIDIA Drive 설치

# sh NVIDIA-Linux-x86_64-358.16.run

runlevel 5 로 변경

# systemctl set-default graphical.target

3. 폰트 설치 및 글꼴 변경

적용할 폰트를 아래 위치에 복사한다.

$ mkdir .local/share/fonts
$ cp <font ttf file> .local/share/fonts

폰트 변경

Gnome Menu 에서 프로그램>유틸리티>Tweak Tool>글꼴

4. 주요 yum repo 설정

# rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

# vi /etc/yum.repos.d/centos.repo

# yum repolist
# yum install hdparm

# rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm
# yum repolist

# yum –enablerepo=nux-dextop install <package-name>

5. Mate Desktop 설치하기 및 설정하기

RHEL7 에서는 gnome-shell을 이요할 수 있는 gnome3  혹은 gnome classic이 기본
환경으로 제공된다.

gnome2 기반의 UI에 익숙한 사용자의 경우 mate desktop을 설치하면 거의 동일한
UI 환경으로 사용이 가능하다.

또한 이전에 compiz 와 같은 3D desktop 효과를 이용한 사용자라면 xfce 혹은
mate desktop 으로 데스크탑 환경을 변경해야 한다. gnome3 는 자체적으로 3D 관련
효과가 기본적으로 제공되기 때문에 compiz 를 실행하면 충돌이 발생하게 된다.

개인적으로 compiz-fusion 환경을 선호하는 관계로 mate desktop 을 설치하도록
한다.

# yum groupinstall “MATE Desktop”

현재 접속된 gnome 세션에서 로그오프 하고 다시 GDM 로그인 창의 설정아이콘을 클릭하면
하단에 표시된 “그놈” 을 선택한다.

이제 RHEL5~6 환경에서의 gnome desktop 과 유사한 UI 가 나타난다.

– 한영전환 방식 : ibus-setup 실행, 일반탭>다음입력 방식 : <Shift>space 로 변경

– 폰트변경 : gnome 메뉴>기본설정>시스템>모양새>모양>글꼴

– GTK Themes 설치 : Mac4Lin, Paper 추천

$ wget http://jaist.dl.sourceforge.net/project/mac4lin/mac4lin/ver.1.0/Mac4Lin_Install_v1.0.zip
$ mkdir Mac4Lin
$ mv Mac4Lin_Install_v1.0.zip Mac4Lin
$ cd Mac4Lin
$ unzip Mac4Lin_Install_v1.0.zip
$ cd Mac4Lin_Install_v1.0/
$ sudo ./Mac4Lin_Install_v1.0.sh

# rpm -ivh paper-gtk-theme-3.9.2-1.20150205giteefb7ea.fc20.noarch.rpm
# paper-icon-theme-3.9.2-1.20150205gitaca8802.fc20.noarch.rpm

$ wget http://faenza-icon-theme.googlecode.com/files/faenza-icon-theme_1.3.zip
$ mkdir faeza ; mv faenza-icon-theme_1.3.zip faeza; cd faeza
$ unzip faenza-icon-theme_1.3.zip

우측작업공간으로 창이동 > Ctrl + Alt + Right

6. Compiz 설치하기 및 설정하기

compiz 관련 패키지는 yum repo 구성 시 nux 사이트에서 제공하게 된다.

# yum install compiz compiz-manager compiz-mate compizconfig-python libcompizconfig emerald-themes* ccsm compiz-plugin-main* compiz-plugins-extra* compiz-manager fusion-icon fusion-icon-gtk emerald emerald-devel

# yum install Pyrex

만일 Nux 사이트가 더이상 접속이 불가한 경우엔 Fedora 19, 20 버전에서 제공하는
compiz 관련 Source RPM 를 rebuild 하여 적용이 가능하다.

compiz-fusion 의 세부적인 설정은 RHEL6_install 문서를 참고하길 바람.

– compiz-fusion 접근성 설정하기

기본 zoom 기능의 경우 화면만 확대되고, 확대된 화면을 제어할수 없다.
하지만 enhanced zoom 은 확대된 화면을 제어할 수가 있다.

7. 주요 응용 S/W 설치

# yum install xulrunner

– google chrome browser

# wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm

google chrome 을 설치하고 인터넷에 접속하면 google 이나 naver 등의 검색 input box 에
한글글자가 거칠게 나올 수 있다.

이때는 google chrome 의 확장 프로그램 중 webfont css 관련 확장 프로그램을 설치하여
해결이 가능하다.

크롬 웹스토어에서 확장프로그램 Font Changer with google web font를 설치합니다.
(크롬 브라우저에서 https://chrome.google.com/webstore/category/extensions?hl=ko

주소창 우측상단에 FC라는 로고 아이콘이 생성됩니다.
클릭하여 Font name 아래의 Edit Custom Font를 클릭
나눔고딕 폰트 추가..

이 방법을 사용할 경우 간혹 기호 문자가 깨지는 경우가 있음.

이런 경우는 확장프로그램으로 Font Chager 대신 stylebot을 설치하고,
Stylebot Option>Styles>Global Sttylesheet>”Edit Global Stylesheet” 버튼 선택

input {
font-family: Nanum Gothic;
text-shadow: #fff 0px 1px 1px;
text-stroke: 1px rgba(0,0,0,0.1);
font-size: 15px;
}

body, td, textarea, select, div, p, span, code,font {
font-family: Nanum Gothic;
text-shadow: 1px 1px 1px rgba(0,0,0,0.1);
text-stroke: 0.6px;
font-size: 12px;
}

입력하여 해결 가능하다.
