linux tigervnc-server安装使用

一,安装tigervnc-server VNC软件包

[root@localhost ~]# yum install tigervnc-server

[root@localhost ~]# rpm -qc tigervnc-server

/etc/sysconfig/vncservers

[root@localhost ~]# chkconfig --level 35 vncserver on

二.目的:以vistor用户启动第一个端口,即5901,以student用户启动第二个端口,即5902

[root@localhost ~]# vim /etc/sysconfig/vncservers

VNCSERVERS="1:visitor 2:student"

以vnc使用用户登录系统,创建vnc密码,vncpasswd

[root@localhost ~]# su - visitor

[visitor@localhost ~]$ vncpasswd

Password: 输入密码

Password must be at least 6 characters - try again

Password: 再次输入密码

Verify:

启动服务一次,生成 /home/visitor/.vnc/xstartup

[visitor@localhost ~]$ vncserver 

New 'localhost.localdomain:1 (visitor)' desktop is localhost.localdomain:1

Starting applications specified in /home/visitor/.vnc/xstartup

Log file is /home/visitor/.vnc/localhost.localdomain:1.log

查看已经打开的vnc服务,关闭服务

[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

Starting applications specified in /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,启动服务

[root@localhost ~]# /etc/init.d/vncserver start

正在启动 VNC 服务器：1:visitor 

New 'localhost.localdomain:1 (visitor)' desktop is localhost.localdomain:1

Starting applications specified in /home/visitor/.vnc/xstartup

Log file is /home/visitor/.vnc/localhost.localdomain:1.log

2:student 

New 'localhost.localdomain:2 (student)' desktop is localhost.localdomain:2

Starting applications specified in /home/student/.vnc/xstartup

Log file is /home/student/.vnc/localhost.localdomain:2.log

                                                           [确定]

四.添加防火墙配置

[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  ]

iptables: Applying firewall rules:                         [  OK  ]

五.远程访问

六.使用安全的SSH进行连接

VNC 是明文的,不安全的.连接过程可能会被窃听,干扰.可以使用SSH通道加密,然后再由远程主机的回环地址通信,加大了安全性.

[root@localhost ~]# vim /etc/sysconfig/vncservers

VNCSERVERARGS[1]="-localhost"

[11:30:18 talen@BJB0300 ~ ]$ vncviewer -via visitor@172.31.0.128 localhost:1

这里的localhost是远程主机的回环地址,由远程主机解析

七.生成密码文件,无输入密码登录

[root@localhost ~]# vncpasswd virtual

Password:

Verify:

[13:43:02 talen@BJB0300 study ]$ vncviewer -passwd ~/study/virtual -via root@172.31.0.128 localhost:3

八.多用户配置

 VNCSERVERS="3:root 2:student"

 VNCSERVERARGS[2]="-geometry 800x600 -localhost"

 VNCSERVERARGS[3]="-geometry 1024x768 -localhost"
