ln -sf /lib/systemd/system/runlevel5.target /etc/systemd/system/default.target

# ln -sf /lib/systemd/system/runlevel3.target /etc/systemd/system/default.target

yum install tigervnc-server

cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:2.service

vi /etc/systemd/system/vncserver@:2.service

(유저부분을 2군데 바꿔준다.)

firewall-cmd --permanent --zone=public --add-service vnc-server

firewall-cmd --reload

vncserver

systemctl daemon-reload

4) VNC 서버 시작 

systemctl start vncserver@:2.service

디스플레이번호 2번의 VNC서버를 시작한다. 

서버 부팅 시 자동으로 서비스가 실행될 수 있게 다음과 같이 설정한다.

~]# systemctl enable vncserver@:2.service

VNC 서버 재시작

systemctl daemon-reload

6) VNC 서버 비활성화

~]# systemctl stop vncserver@:2.service 

디스플레이번호 2번의 VNC서버 서비스를 종료한다.

서버 부팅 시 자동으로 서비스가 실행되는 부분을 다음과 같이 제거한다.

~]# systemctl disable vncserver@:2.service

VNC서버 프로그램을 설치하였다면 VNC 서버 설정을 해야 한다.

CentOS 6 이하 버전은 /etc/sysconfig/vncservers 파일을 편집기로 열어 설정하였지만 

CentOS 7 부터는 /lib/systemd/system/vncserver@.server으로 변경되었고 

vncserver@.service 파일을 vncserver@:디스플레이번호.service 형식으로 복사하여 사용한다.

예를 들면 디스플레이 번호 2번을 사용하고자 한다면 다음과 같이 복사한다.

cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:2.service
