1. 安裝圖形化界面

# yum check-update
# yum groupinstall "X Window System"
# yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts

或者直接

yum groupinstall "GNOME Desktop" "Graphical Administration Tools"

### 設(shè)置默認(rèn)啟動(dòng)圖形界面
# unlink /etc/systemd/system/default.target
# ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
# reboot

2.安裝 tigervnc server and X11 fonts

yum install tigervnc-server xorg-x11-fonts-Type1

拷貝VNC server configuration 文件到 /etc/systemd/system 下進(jìn)行配置。VNC默認(rèn)端口為5900，你可以直接通過5900端口登錄VNC，也可以自己設(shè)置一個(gè)子端口。比如，我將子端口設(shè)成5，那么登錄的端口就是5905,你可以通過ipaddress:sub-port(192.168.1.1:5或者192.168.1.1:5905)來登錄。

# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:5.service
# vi /etc/systemd/system/vncserver@:5.service

默認(rèn)配置文件的內(nèi)容

[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target
[Service]
Type=forking
# Clean any existing files in /tmp/.X11-unix environment
ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
ExecStart=/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"

ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
[Install]
WantedBy=multi-user.target

將<USER>替換成你的用戶名字，例如 archie

[Unit]

After=syslog.target network.target
[Service]
Type=forking
# Clean any existing files in /tmp/.X11-unix environment
ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
ExecStart=/sbin/runuser -l archie-c "/usr/bin/vncserver %i"
PIDFile=/home/archie/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
[Install]
WantedBy=multi-user.target

添加防火墻規(guī)則

# firewall-cmd --permanent --zone=public --add-port=5905/tcp
# firewall-cmd --reload

3. 配置啟動(dòng)vncserver

切換到archie用戶, 啟動(dòng)vncserver 并配置密碼

[archlie@server ~]$ vncserver
You will require a password to access your desktops.

Password:
Verify:
xauth:  file /home/archie/.Xauthority does not exist

New 'localhost.localdomain:1 (raj)' desktop is server.itzgeek.com:1

Creating default startup script /home/archie/.vnc/xstartup
Starting applications specified in /home/archie/.vnc/xstartup
Log file is /home/archie/.vnc/server.itzgeek.com:1.log

切換到root用戶，重啟systemctl daemon,啟動(dòng)vncserver

systemctl daemon-reload
systemctl start vncserver@:5.service
systemctl enable vncserver@:5.service

然后通過ipaddress:5905 or ipaddress:5登錄遠(yuǎn)程服務(wù)器
