RHEL7.X配置VNC服务方法与步骤

1、安装X套件，注意大小写；

[root@dazhi /]# yum groupinstall -y 'Server with GUI'

 

2、安装tigervnc-server软件包；

[root@dazhi /]# yum -y install tigervnc-server

 

3、配置VNC；

[root@dazhi /]# cat /etc/sysconfig/vncservers

# THIS FILE HAS BEEN REPLACED BY /lib/systemd/system/vncserver@.service

[root@dazhi /]#

 

查看/lib/systemd/system/vncserver@.service配置示例；

[root@dazhi /]# cat /lib/systemd/system/vncserver@.service

 

# The vncserver service unit file

#

# Quick HowTo:

# 1. Copy this file to /etc/systemd/system/vncserver@.service

# 2. Replace <USER> with the actual user name and edit vncserver

#    parameters appropriately

#    (ExecStart=/usr/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"

#     PIDFile=/home/<USER>/.vnc/%H%i.pid)

# 3. Run `systemctl daemon-reload`

# 4. Run `systemctl enable vncserver@:<display>.service`

#

# DO NOT RUN THIS SERVICE if your local area network is

# untrusted!  For a secure way of using VNC, you should

# limit connections to the local host and then tunnel from

# the machine you want to view VNC on (host A) to the machine

# whose VNC output you want to view (host B)

#

# [user@hostA ~]$ ssh -v -C -L 590N:localhost:590M hostB

#

# this will open a connection on port 590N of your hostA to hostB's port 590M

# (in fact, it ssh-connects to hostB and then connects to localhost (on hostB).

# See the ssh man page for details on port forwarding)

#

# You can then point a VNC client on hostA at vncdisplay N of localhost and with

# the help of ssh, you end up seeing what hostB makes available on port 590M

#

# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.

#

# Use "-localhost" to prevent remote VNC clients connecting except when

# doing so through a secure tunnel.  See the "-via" option in the

# `man vncviewer' manual page.

4、启动VNC服务；

[root@dazhi /]# systemctl daemon-reload

[root@dazhi /]# systemctl enable vncserver@:1.service

[root@dazhi /]# systemctl start vncserver@:1.service

 

5、查看VNC服务（注：要查看某个用户的VNC服务，需要切换到该用户下执行vncserver -list）；

[root@dazhi /]# vncserver -list

 

TigerVNC server sessions:

 

X DISPLAY #    PROCESS ID

:1        25925

[root@dazhi /]# su - dazhi

Last login: Fri Aug  6 14:21:45 CST 2021 on pts/1

[dazhi@dazhi ~]$ vncserver -list

 

TigerVNC server sessions:

 

X DISPLAY #    PROCESS ID

:2        26613

[dazhi@dazhi ~]$ exit

logout

[root@dazhi /]# su - weblogic

Last login: Fri Aug  6 14:20:22 CST 2021 on pts/1

[weblogic@dazhi ~]$ vncserver -list

 

TigerVNC server sessions:

 

X DISPLAY #    PROCESS ID

:3        27576

[weblogic@dazhi ~]$

 

6、关闭VNC服务（注：关闭VNC服务需要切换到对应用户下执行）；

[root@dazhi /]# vncserver -list

 

TigerVNC server sessions:

 

X DISPLAY #    PROCESS ID

:1        25925

[root@dazhi /]# vncserver -kill :1

Killing Xvnc process ID 25925

[root@dazhi /]# vncserver -list

 

TigerVNC server sessions:

 

X DISPLAY #    PROCESS ID

[root@dazhi /]#

 

7、调整VNC界面分辨率，先执行xrandr查看当前服务器支持分辨率情况，然后执行xrandr -s 1920x1080修改自己想要的分辨率。
