VNC Server (CentOS 7 GNOME)

1. 安装VNC服务

sudo yum install tigervnc-server -y

2. 启动VNC服务，设置密码，然后停止

vncserver :1

vncserver -kill :1

3. 配置为开机启动

sudo cp /lib/systemd/system/vncserver@.service /etc/systemd/system/

sudo vim /etc/systemd/system/vncserver@.service

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

[Service]
Type=forking
ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
ExecStart=/usr/sbin/runuser -l USERNAME -c "/usr/bin/vncserver %i"
PIDFile=/home/USERNAME/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

[Install]
WantedBy=multi-user.target

sudo systemctl daemon-reload

sudo systemctl enable vncserver@:1.service

经过实验，vnc连上后黑屏可以通过修改xstartup文件解决，只保留前面几行：

#!/bin/sh

unset SESSION_MANAGER

unset DBUS_SESSION_BUS_ADDRESS

exec /etc/X11/xinit/xinitrc
