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 || :'
上述内容中最好设置为root用户，否则可能会看到以下报错：
vncserver@:1.service - Remote desktop service (VNC) Loaded: loaded (/usr/lib/systemd/system/vncserver@:1.service; enabled) Active: failed (Result: exit-code) since Tue 2015-04-14 10:09:24 CST; 1min 36s ago Process: 3258 ExecStart=/sbin/runuser -l sysadmin -c /usr/bin/vncserver %i (code=exited, status=1/FAILURE) Process: 3254 ExecStartPre=/bin/sh -c /usr/bin/vncserver -kill %i > /dev/null 2>&1 || : (code=exited, status=0/SUCCESS) Apr 14 10:09:24 F1A-VMHOST-SWPE systemd[1]: Starting Remote desktop service (VNC)...
