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;
-
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 environment
-
ExecStartPre=/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.pid
-
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
1.设置为非root用户报错:
-

2.Type=forking报错,改为Type=simple
-
[root@localhost system]# systemctl start 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
