一,安裝tigervnc-server vnc軟體包
[root@localhost ~]# yum install tigervnc-server
設定開機自啟動
[root@localhost ~]# chkconfig --level 35 vncserver on
檢視配置檔案所在位置
[root@localhost ~]# rpm -qc tigervnc-server
/etc/sysconfig/vncservers
二.目的:以vistor使用者啟動第乙個埠,即5901,以student使用者啟動第二個埠,即5902
[root@localhost ~]# vim /etc/sysconfig/vncservers
vncservers="1:visitor 2:student"
vncserverargs[1]="-geometry 1400x900 -nolisten tcp -localhost
vncserverargs[2]="-geometry 1400x900 -nolisten tcp -localhost
以vnc使用使用者登入系統,建立vnc密碼,vncpasswd
[root@localhost ~]# su - visitor
[visitor@localhost ~]$ vncpasswd
password: 輸入密碼
password must be at least 6 characters - try again
password: 再次輸入密碼
verify:
啟動服務一次,生成 /home/visitor/.vnc/xstartup
[visitor@localhost ~]$ vncserver
new 'localhost.localdomain:1 (visitor)' desktop is localhost.localdomain:1
log file is /home/visitor/.vnc/localhost.localdomain:1.log
檢視已經開啟的vnc服務,關閉服務
[visitor@localhost ~]$ vncserver -list
tigervnc server sessions:
x display # process id
:1 5567
[visitor@localhost ~]$ vncserver -kill :1
killing xvnc process id 5567
[visitor@localhost ~]$ exit
logout
[root@localhost ~]# su - student
[student@localhost ~]$ vncpasswd
password:
verify:
[student@localhost ~]$ vncserver
xauth: creating new authority file /home/student/.xauthority
new 'localhost.localdomain:1 (student)' desktop is localhost.localdomain:1
creating default startup script /home/student/.vnc/xstartup
log file is /home/student/.vnc/localhost.localdomain:1.log
[student@localhost ~]$ vncserver -list
tigervnc server sessions:
x display # process id
:1 8764
[student@localhost ~]$ vncserver -kill :1
killing xvnc process id 8764
[student@localhost ~]$ exit
logout
三,啟動服務
[root@localhost ~]# /etc/init.d/vncserver start
正在啟動 vnc 伺服器：1:visitor
new 'localhost.localdomain:1 (visitor)' desktop is localhost.localdomain:1
log file is /home/visitor/.vnc/localhost.localdomain:1.log
2:student
new 'localhost.localdomain:2 (student)' desktop is localhost.localdomain:2
log file is /home/student/.vnc/localhost.localdomain:2.log
[確定]
四.新增防火牆配置
[root@localhost ~]# vim /etc/sysconfig/iptables
-a input -m state --state new -m tcp -p tcp --dport 5901 -j accept
-a input -m state --state new -m tcp -p tcp --dport 5902 -j accept
[root@localhost ~]# service iptables restart
iptables: flushing firewall rules: [ ok ]
iptables: setting chains to policy accept: filter [ ok ]
iptables: unloading modules: [ ok ]
五.遠端訪問
六.使用安全的ssh進行連線
vnc 是明文的,不安全的.連線過程可能會被竊聽,干擾.可以使用ssh通道加密,然後再由遠端主機的回環位址通訊,加大了安全性.
[root@localhost ~]# vim /etc/sysconfig/vncservers
vncserverargs[1]="-localhost"
[11:30:18 talen@bjb0300 ~ ]$ vncviewer -via [email protected] localhost:1
這裡的localhost是遠端主機的回環位址,由遠端主機解析
七.生成密碼檔案,無輸入密碼登入
[root@localhost ~]# vncpasswd virtual
password:
verify:
[13:43:02 talen@bjb0300 study ]$ vncviewer -passwd ~/study/virtual -via [email protected] localhost:3
八.多使用者配置
vncservers="3:root 2:student"
vncserverargs[2]="-geometry 800x600 -localhost"
vncserverargs[3]="-geometry 1024x768 -localhost"
VNC的安裝和配置
服務端環境 centos 6.7 客戶端環境 windows 7 可以直接rpm安裝vnc的服務端 rpm ivh tigervnc server 1.1.0 16.el6.x86 64.rpm如果rpm安裝時發現有依賴，建議直接使用yum安裝，輕鬆解決依賴問題 yum install tigerv...
