以32313133353236313431303231363533e59b9ee7ad9431333365633863root用户运行以下命令来安装vncserver;

yum install tigervnc-server

同样运行以下命令来安装vncviewer;

yum install vnc

停止并禁用防火墙；

systemctl stop firewalld.service

systemctl disable firewalld.service

二.配置

vncviewer基本上不用配置；

vncserver的配置，创建一个新的配置文件，以开启1号窗口为例(也可以同时开启多个窗口，修改数字即可)，方法如下：

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

或者再增加一个窗口：

cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:2.service

编辑/lib/systemd/system/vncserver@:1.service,设置用户root相关参数,最终内容如下：

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

1.设置为非root用户报错：[root@localhost system]# systemctl status -l vncserver@:2.service

3.vnc viewer客户端连接黑屏

改变xstartup的权限

这个问题是很多人容易忽视的问题，也是造成连接成功后黑屏的原因之一。

在CentOS中，xstartup的文件路径为：/root/.vnc/ (可以通过locate xstartup来查看xstartup的文件路径)

所以需要执行：chmod 777 /root/.vnc/xstartup

关闭防火墙

systemctl stop firewalld.service #停止

systemctl disable firewalld.service #禁用

三.应用

更新systemctl以使其生效；

systemctl daemon-reload

设置vncserver的密码；

vncpasswd root

按提示输入密码以及确认密码

启动该服务用来启用vnc的1号窗口；

systemctl start vncserver@:1.service  或者 vncserver :1

关闭1号窗口：

systemctl stop vncserver@:1.service   或者 vncserver -kill :1

设置为开机自动启动；

systemctl enable vncserver@:1.service
