CentOS 7 vncserver 설치

TigerVNC is a high-performance, platform-neutral implementation of VNC (Virtual Network Computing), a client/server application that allows users to launch and interact with graphical applications on remote machines. TigerVNC provides the levels of performance necessary to run 3D and video applications, and it attempts to maintain a common look and feel and re-use components, where possible, across the various platforms that it supports. TigerVNC also provides extensions for advanced authentication methods and TLS encryption

client 에는 tigervnc site 에서 다운받을수 있습니다.

http://tigervnc.org/

 

vncserver접속 vncport 의 경우 5901 port 를 사용하며 vnc-client 에서는 편의상 1 로 입력합니다.

password 입력후 vnc접속 확인을 할수 있습니다. 

 

vnc-server 가 정상적으로 동작을 하지 않을 경우

/root/.vnc 디렉토리의 *.log 및 *.pid 삭제

/tmp/.X11-unix 디렉토리의 X로 시작하는 파일을 삭제후 재시작 하시면 됩니다.

ex)

[root@test-machine ~]# cd .vnc/
[root@test-machine .vnc]# rm -f test-machine\:6.*
[root@test-machine .vnc]# cd /tmp/
[root@test-machine tmp]# rm .X11-unix/ -rf

CentOS 의 경우 Desktop 의 경우 yum groupinstall 로 간단하게 설치 할수 있습니다.

Runlevel 의 경우 기존에는 /etc/inittab 에서 지정을 하였지만 CentOS7 에서는 systemctl set-default 로 지정 할수 있습니다.

 

 

패키지 설치

[root@centos74 ~]# yum groupinstall "GNOME Desktop" -y

 

runlevel 확인 및 runlevel 변경후 시스템 리부팅

[root@centos74 ~]# systemctl get-default
multi-user.target
[root@centos74 ~]# systemctl set-default graphical.target
Removed symlink /etc/systemd/system/default.target.
Created symlink from /etc/systemd/system/default.target to /usr/lib/systemd/system/graphical.target.
[root@centos74 ~]#
[root@centos74 ~]# init 6

 

최소설치 에서 gnome desktop 을 설치 하면 아래와 같은 화면을 볼수 있습니다.

1을 눌러 License information 을 선택 합니다.

 

2를 눌러 I accept the license agreement 를 선택 합니다.

 

c를 눌러 설정을 마무리 합니다.
