CentOS7下安装配置vncserver

Posted 2021-10-22

一.安装
1、以root用户运行以下命令来安装vncserver和gnome;
yum install tigervnc-server tigervnc-server-module
yum groupinstall -y "GNOME Desktop"
2、同样运行以下命令来安装vncviewer;
yum install vnc

3、停止并禁用防火墙
systemctl stop firewalld.service
systemctl disable firewalld.service

vi /etc/selinux/config

set "SELINUX=disabled" and comment the rest lines.

二.配置
1、vncviewer基本上不用配置；
2、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/[email protected] /lib/systemd/system/[email protected]:1.service
编辑/lib/systemd/system/[email protected]: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：
[email protected]:1.service - Remote desktop service (VNC)

Loaded: loaded (/usr/lib/systemd/system/[email protected]:1.service; enabled)

Active: failed (Result: exit-code) since Tue 2015-04-14 10:09:24 CST; 1min 36s ago

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)...

Apr 14 10:09:24 F1A-VMHOST-SWPE systemd[1]: Unit [email protected]:1.service entered failed state.

Warning: Unit file changed on disk, ‘systemctl daemon-reload‘ recommended.

三.应用
1、更新systemctl以使其生效；
systemctl daemon-reload

2、设置vncserver的密码；
vncpasswd root
按提示输入密码以及确认密码

3、启动该服务用来启用vnc的1号窗口；
systemctl start [email protected]:1.service 或者 vncserver :1
关闭1号窗口：
systemctl stop [email protected]:1.service 或者 vncserver -kill :1

4、设置为开机自动启动；
systemctl enable [email protected]:1.service

5、若发现启动失败，则重启一次系统，然后重新启动1号窗口
6、在windows上安装客户端软件VNCView
假设linux服务器IP为192.168.1.24,开的窗口为1，则连接时如下：
