最近，由於專案需要，必須要在centos下進行操作。習慣了圖形介面的我，通過黑框框來遠端操作伺服器，著實讓人難受。但是，windows自帶的遠端桌面工具貌似不能直接連centos。所以，只能藉助其他工具來實現這一目的。好了，廢話不多說，下面，就把我的成功方案總結一下。
注：centos版本為7，windows版本為8

1.伺服器端（centos）

安裝元件

yum install -y vnc-server

配置檔案

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

檔案[email protected]:1.service的內容：

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

# 3. Run `systemctl daemon-reload`
# 4. Run `systemctl enable [email protected]:<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)
#
# [[email protected] ~]$ 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.


[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=/usr/sbin/runuser -l admin -c "/usr/bin/vncserver %i"
PIDFile=/home/admin/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

[Install]
WantedBy=multi-user.target

需要修改的部分：

[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=/usr/sbin/runuser -l <User> -c "/usr/bin/vncserver %i"
PIDFile=/home/<User>/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

把這部分中的<User>都改成admin，即遠端登入的使用者名稱

重新載入[email protected]:1.service

[root@localhost /]# systemctl daemon-reload

設定密碼

[root@localhost /]# vncpasswd

設定開機啟動

[root@localhost /]# systemctl enable [email protected]:1.service

啟動服務

[root@localhost /]# systemctl start [email protected]:1.service

防火牆設定

關閉防火牆

[root@localhost /]# systemctl stop firewalld

OR
新增埠

關閉服務

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

2.客戶端（windows）

檔案下載

軟體配置
