一.安装

以root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；

1. systemctl stop firewalld.service

2. 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：

1. [Unit]

2. Description=Remote desktop service (VNC)

3. After=syslog.target network.target

4. [Service]

5. Type=forking

6. #Clean any existing files in /tmp/.X11-unix environment

7. ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

8. ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i"

9. PIDFile=/root/.vnc/%H%i.pid

10. ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

1.设置为非root用户报错：

1. [root@localhost system]# systemctl status -l vncserver@:2.service

2. vncserver@:2.service - Remote desktop service (VNC)

3. Loaded: loaded (/etc/systemd/system/vncserver@:2.service; enabled; vendor preset:

2. Job for vncserver@:2.service failed because the control process exited with error code. See

3. "systemctl status vncserver@:2.service" and "journalctl -xe" for details.

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
