Linux7.6快速安装tigervnc1.8

前置配置：

配置yum环境：确保Linux7.6安装盘存在于光驱中（或虚拟光驱）

mkdir /mnt/linux
mount /dev/cdrom /mnt/linux
cd /etc/yum.repos.d
mkdir bk
mv *.repo bk/
echo "[EL]" >> /etc/yum.repos.d/yuminstall.repo 
echo "name =Linux 7.x DVD" >> /etc/yum.repos.d/yuminstall.repo 
echo "baseurl=file:///mnt/linux" >> /etc/yum.repos.d/yuminstall.repo 
echo "gpgcheck=0" >> /etc/yum.repos.d/yuminstall.repo 
echo "enabled=1" >> /etc/yum.repos.d/yuminstall.repo
cat /etc/yum.repos.d/yuminstall.repo

VNC安装及配置

1.安装X-windows套件（已安装的跳过）

yum groupinstall -y 'Server with GUI'

2. 安装tigervnc-server

yum install -y tigervnc-server

3.配置vnc

// [email protected] 这是模板文件
cat /lib/systemd/system/[email protected]

该模板显示以下内容：

# 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 appropriately
#    (ExecStart=/usr/sbin/runuser -l  -c "/usr/bin/vncserver %i"
#     PIDFile=/home//.vnc/%H%i.pid)
# 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.

参照模板文件中的注释说明，将该文件拷贝至/etc/systemd/system/下，并改名

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

编辑新文件：

vim /etc/systemd/system/vncserver@:1.service

修改如下：
