Centos7 采用mini安装，如果想远程桌面，那就需要安装图形界面
# yum check-update# yum groupinstall "X Window System"# yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts# unlink /etc/systemd/system/default.target# ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target# reboot
下面开始安装：
1、安装tigervnc# yum install tigervnc-server -y
2、从VNC备份库中复制service文件到系统service服务管理目录
# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service
3、修改配置文件
# vim /etc/systemd/system/vncserver@:1.service
#改成root用户启动，配置文件看起来这样的
[Unit]Description=Remote desktop service (VNC)After=syslog.target network.target[Service]Type=forkingUser=root# Clean any existing files in /tmp/.X11-unix environmentExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'ExecStart=/usr/sbin/runuser -l root -c "/usr/bin/vncserver %i"PIDFile=/root/.vnc/%H%i.pidExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'[Install]WantedBy=multi-user.target
4、启动服务
重启进程# systemctl daemon-reload
设置VNC密码
[root@local ~]# vncpasswdPassword:Verify:Would you like to enter a view-only password (y/n)? nA view-only password is not used
设置开机启动及启动进程
[root@local ~]# systemctl enable vncserver@:1.serviceCreated symlink from /etc/systemd/system/multi-user.target.wants/vncserver@:1.service to /etc/systemd/system/vncserver@:1.service.[root@local ~]# systemctl start vncserver@:1.service[root@local ~]# systemctl status vncserver@:1.service● vncserver@:1.service - Remote desktop service (VNC) Loaded: loaded (/etc/systemd/system/vncserver@:1.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2019-02-05 00:06:57 GMT; 7s ago Process: 58790 ExecStart=/usr/sbin/runuser -l root -c /usr/bin/vncserver %i (code=exited, status=0/SUCCESS) Process: 58778 ExecStartPre=/bin/sh -c /usr/bin/vncserver -kill %i > /dev/null 2>&1 || : (code=exited, status=0/SUCCESS) Main PID: 58831 (Xvnc) CGroup: /system.slice/system-vncserver.slice/vncserver@:1.service ‣ 58831 /usr/bin/Xvnc :1 -auth /root/.Xauthority -desktop cfl-lab.communit...Feb 05 00:06:53 cfl-lab.communityfibre.co.uk systemd[1]: Starting Remote desktop ser....Feb 05 00:06:57 cfl-lab.communityfibre.co.uk systemd[1]: Started Remote desktop serv....Hint: Some lines were ellipsized, use -l to show in full.
5、防火墙设置
关闭防火墙，或者放行5901端口。6、VNC远程连接
现在用VNC可以远程连接了，VNC Server那里填写的是<服务器IP地址>:5901
