4.關閉防火牆
| 1 2 |
[root@s10 ~]# systemctl stop firewalld
[root@s10 ~]# systemctl disable firewalld
|
5.複製配置檔案
| 1 |
[root@s10 ~]# cp /lib/systemd/system/[email protected] /etc/systemd/system/vncserver@:1.service
|
6.修改配置檔案

[root@s10 ~]# vim /etc/systemd/system/vncserver@\:1.service
1# The vncserver service unit file

5# 2. Replace <USER> with the actual user name and edit vncserver

8# PIDFile=/home/<USER>/.vnc/%H%i.pid)
9# 3. Run `systemctl daemon-reload`
10# 4. Run `systemctl enable vncserver@:<display>.service`
11#
12# DO NOT RUN THIS SERVICE if your local area network is
13# untrusted! For a secure way of using VNC, you should
14# limit connections to the local host and then tunnel from
15# the machine you want to view VNC on (host A) to the machine
16# whose VNC output you want to view (host B)
17#
18# [user@hostA ~]$ ssh -v -C -L 590N:localhost:590M hostB
19#
20# this will open a connection on port 590N of your hostA to hostB's port 590M
21# (in fact, it ssh-connects to hostB and then connects to localhost (on hostB).
22# See the ssh man page for details on port forwarding)
23#
24# You can then point a VNC client on hostA at vncdisplay N of localhost and with
25# the help of ssh, you end up seeing what hostB makes available on port 590M
26#
27# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
28#
29# Use "-localhost" to prevent remote VNC clients connecting except when
30# doing so through a secure tunnel. See the "-via" option in the
31# `man vncviewer' manual page.

將第43、44行中的<USER>修改為root或者你想通過vnc登入的賬號，如tom 或jerry 如下所示：

43 ExecStart=/usr/sbin/runuser-l root -c"/usr/bin/vncserver %i"
44 PIDFile=/root/.vnc/%H%i.pid
