CentOS7.x安装VNC

1、安装GNOME Desktop

yum groupinstall "GNOME Desktop" 

修改默认启动方式为图形化界面

systemctl set-default graphical.target

如果要换回成命令模式

systemctl set-default multi-user.target

2、安装VNC

yum install tigervnc-server

复制VNC启动脚本

cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service

vncserver@:1.service中的:1表示"桌面号",启动的端口号就是5900+桌面号,即是5901,如果再有一个就是2啦,端口号加1就是5902,以此类推。

编辑服务启动脚本vi /etc/systemd/system/vncserver@\:1.service

# the help of ssh, you end up seeing what hostB makes available on port 590M
#
# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
#
# Use "-localhost" to prevent remote VNC clients connecting except when
# doing so through a secure tunnel.  See the "-via" option in the
# `man vncviewer' manual page.


[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=/usr/bin/vncserver_wrapper <USER> %i
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

[Install]
WantedBy=multi-user.target

找到其中的<USER> ,修改成自己的用户名,如 :root

设置vnc密码

vncpasswd

启动服务

systemctl start vncserver@\:1.service

新增和修改配置文件发生变化时都需要执行daemon-reload子命令重新加载配置文件

systemctl daemon-reload

加入开机启动

systemctl enable vncserver@\:1.service

3、开放防火墙的5901端口:

firewall-cmd --zone=public --add-port=5901/tcp --permanent
