centos7安装vnc远程桌面

 

一：安装GNOME Desktop图形桌面服务

二：安装VNC

三：修改系统运行状态，启动桌面模式

四：设置vnc用systemctl来管理(第一个用户vncserver@:1.service,第二个用户vncserver@:2.service,其他以此类推)

五：修改VNC用户root（其他系统用户也可以这样改）

六：启动，关闭，重启，查看VNC命令

七：下载VNC客户端

---

一：安装GNOME Desktop图形桌面服务

### 关闭防火墙
[root@localhost ~]# systemctl stop firewalld

[root@localhost ~]# yum groupinstall "GNOME Desktop" -y

执行上面命令可能会报错

 解决方案

[root@localhost ~]# yum update grub2-common

[root@localhost ~]# rpm -q grub2-common
grub2-common-2.02-0.81.el7.centos.noarch

[root@localhost ~]# yum install fwupdate-efi

二：安装VNC

[root@localhost ~]# yum install tigervnc-server

三：修改系统运行状态，启动桌面模式

systemctl set-default graphical.target由命令行模式更改为图形界面模式
systemctl set-default multi-user.target由图形界面模式更改为命令行模式

[root@localhost ~]# systemctl get-default

[root@localhost ~]# systemctl set-default graphical.target

[root@localhost ~]# init 5

[root@localhost ~]# ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target

四：设置vnc用systemctl来管理(第一个用户vncserver@:1.service,第二个用户vncserver@:2.service,其他以此类推)

[root@localhost ~]# cp /lib/systemd/system/[email protected] /etc/systemd/system/vncserver@:1.service

五：修改VNC用户root（其他系统用户也可以这样改）

[root@localhost ~]# cat /etc/systemd/system/vncserver@:1.service
# The vncserver service unit file
#
# Quick HowTo:
# 1. Copy this file to /etc/systemd/system/[email protected]
# 2. Replace  with the actual user name and edit vncserver
#    parameters in the wrapper script located in /usr/bin/vncserver_wrapper
# 3. Run `systemctl daemon-reload`
# 4. Run `systemctl enable vncserver@:.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.

WantedBy=multi-user.target


###  刷新systemctl
[root@localhost ~]# systemctl daemon-reload

###  设置vnc密码(第二个用户修改密码，vncpasswd user2,其他以此类推)

[root@localhost ~]# vncpasswd
Password:
Verify:
Would you like to enter a view-only password (y/n)? y
Password:
Verify:

[root@localhost ~]# cat /etc/sysconfig/vncservers
# THIS FILE HAS BEEN REPLACED BY /lib/systemd/system/[email protected]
VNCSERVERS="1:root"
VNCSERVERARGS[1]="-geometry 1024x768 -BlacklistTimeout 0"

六：启动，关闭，重启，查看VNC命令

### 启动
[root@localhost ~]# systemctl start vncserver@:1.service

### 停止
[root@localhost ~]# systemctl stop vncserver@:1.service

### 重启
[root@localhost ~]# systemctl restart vncserver@:1.service

### 查看状态
[root@localhost ~]# systemctl status vncserver@:1.service

七：下载VNC客户端

下载地址

一直点点点就好，安装好之后win+s搜索vnc

 

输入账号密码，连接成功
