# The vncserver service unit file
#
# Quick HowTo:
# 1. Copy this file to /etc/systemd/system/vncserver@:.service
# 2. Edit and vncserver parameters appropriately
# ("runuser -l -c /usr/bin/vncserver %i -arg1 -arg2")
# 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.

RHEL7 配置VNC远程桌面工具
初初接触 Linux，想要彻底抛弃图形界面真心不是一件容易的事情，特别需要开启或关闭某些系统功能时，傻瓜的图形化界面总比仍不娴熟的命令行要靠谱一些，学习是 慢慢积累的过程，不可急也急不来，分享一个 Red Hat Enterprise Linux 7 配置 VNC 的教程给正在学习的朋友！
| RHEL7 配置VNC |
第一步
#检查系统是否有安装tigervnc-server软件包
[root@wanghualang ~]# rpm -qa |grep vnc
gtk-vnc2-0.5.2-7.el7.x86_64
gvnc-0.5.2-7.el7.x86_64
tigervnc-server-minimal-1.2.80-0.30.20130314svn5065.el7.x86_64
tigervnc-license-1.2.80-0.30.20130314svn5065.el7.noarch
#当前系统未装tigervnc-server软件包
第二步
#安装tigervnc-server软件包
[root@wanghualang ~]# cd /my/Packages/
[root@wanghualang Packages]# rpm -ivh tigervnc-server-1.2.80-0.30.20130314svn5065.el7.x86_64.rpm
准备中... ################################# [100%]
正在升级/安装...
1:tigervnc-server-1.2.80-0.30.20130################################# [100%]
#已安装tigervnc-server软件包，另外，/my/Packages 这个路径是我自定义的。
第三步
#验证tigervnc-server软件包是否安装
[root@wanghualang ~]# rpm -qa |grep vnc
gtk-vnc2-0.5.2-7.el7.x86_64
tigervnc-server-1.2.80-0.30.20130314svn5065.el7.x86_64
gvnc-0.5.2-7.el7.x86_64
tigervnc-server-minimal-1.2.80-0.30.20130314svn5065.el7.x86_64
tigervnc-license-1.2.80-0.30.20130314svn5065.el7.noarch
第四步
#创建一个新的VNC配置文件，/lib/systemd/system/vncserver@.service，这是一个配置文件模版，可以拷贝一份出来进行相关修改，比如我这里是开启2号窗口作为远程桌面。
[root@wanghualang ~]# cd /lib/systemd/system
[root@wanghualang system]# cp vncserver@.service vncserver@:2.service
第五步
#使用VI编辑器修改vncserver@:2.service，把如下标红的内容修改为你需要的用户名
[Unit]
Description=Remote desktop service (VNC)

# 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 wanghualang -c "/usr/bin/vncserver %i"
PIDFile=/home/wanghualang/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
[Install]
WantedBy=multi-user.target
#VI 编辑器使用参考：
第六步
#更新systemctl，使刚才的修改生效
[root@wanghualang system]# systemctl daemon-reload
第七步
#设置用户vnc的密码（即第六步中的wanghualang）
[root@wanghualang system]# vncpasswd wanghualang
Password:
Verify:
#再次输入密码进行确认
第八步
#使用2号窗口启动VNC服务
[root@wanghualang system]# vncserver :2
New 'wanghualang.com:2 (root)' desktop is wanghualang.com:2
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/wanghualang.com:2.log
第九步
在Windows下，安装VNC Viewer，输入正确IP地址、窗口号和密码，即可远程。
