《LINUX教程：CentOS安裝使用VNC進行遠程桌面登錄》要點：
本文介紹了LINUX教程：CentOS安裝使用VNC進行遠程桌面登錄，希望對您有用。如果有疑問，可以聯系我們。

以下先容在CentOS 7下安裝vncserver并使用vnc-viewer進行登錄(使用root權限)：

1、運行敕令yum install tigervnc-server安裝vncserver；

2、運行敕令yum install vnc安裝vnc；//感覺不安裝也可以,安裝一下也很快,不要在意這些細節

3、運行命令yum groupinstall "X Window System"安裝X-Window；//之前安裝發現經常無法啟動vncserver,后面通過網上查資料介紹可以安裝X-Window辦理這個 問題

4、安裝中文字符以辦理界面中文亂碼的問題：yum install dejavu-lgc-sans-fonts、yum groupinstall "Fonts" -y

5、禁用防火墻,假如已經禁用防火墻可以跳過這一步：systemctl stop firewalld.service、systemctl disable firewalld.service

6、配置vncserver：
拷貝創建一個新的配置文件,以開啟1號窗口為例,如果必要開啟多個則創建多個配置文件即可：
[root@localhost ~]# cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:1.service
修改配置文件內容
[root@localhost ~]# vi /lib/systemd/system/vncserver@:1.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
# ("User=<USER>" and "/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.

[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target

[Service]
Type=forking
User=root

# Clean any existing files in /tmp/.X11-unix environment
ExecStartPre=-/usr/bin/vncserver -kill %i
ExecStart=/usr/bin/vncserver %i
PIDFile=/root/.vnc/%H%i.pid
ExecStop=-/usr/bin/vncserver -kill %i

[Install]
WantedBy=multi-user.target

7、運行敕令systemctl daemon-reload更新systemctl；

8、運行命令vncpasswd root設置vncserver的暗碼；

9、運行敕令systemctl start vncserver@:1.service(可以運行systemctl enable vncserver@:1.service敕令設置為默認啟動服務)；//啟動不了則重啟一下系統或則查看啟動日志

10、重啟系統后使用VNC-Viewer連接：192.168.10.100:1,輸入設置的暗碼即可登錄.
