centos 7配置vnc并解決黑屏問題

yum grouplist  
yum groupinstall -y "GNOME Desktop" 
systemctl set-default graphical.target  
yum install tigervnc-server -y

cp /lib/systemd/system/[email protected] /etc/systemd/system/[email protected]:1.service

           

修改/etc/systemd/system/[email protected]:1.service檔案為：

[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target

[Service]
Type=simple

# 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 root -c "/usr/bin/vncserver %i -geometry 1280x720"
PIDFile=/root/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

[Install]
WantedBy=multi-user.target
           

儲存後，執行vncpasswd，配置vnc密碼

systemctl daemon-reload
systemctl start [email protected]\:1.service

#防火牆開放端口
iptables -I INPUT -p tcp --dport 5901 -j ACCEPT
           

如果vnc用戶端連接配接黑屏的話，通過下面方法解決：

#安裝MATE桌面
yum groups install "MATE Desktop"
           

修個配置檔案~/.vnc/xstartup為：

#!/bin/sh                   
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources 
xsetroot -solid grey 
vncconfig -iconic & 
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & 
mate-session & 
           

重新開機vnc服務：

systemctl restart [email protected]\:1.service
