centos 6.8 VNC 搭建(詳細)
背景:考慮有些情況下,需要用到圖形化界面操作(如:配置KVM虛擬化),但是又不想去機房,針對這種情況,我們可以配置vnc服務,使得何時何處都可以輕鬆的辦公(只要網絡可達)
首先檢查是否安裝相應的軟件包
redhat@opman ~]$ rpm -qa |grep tigervnc
[redhat@opman ~]$
[redhat@opman ~]$
沒有,則安裝!
yum -y install tigervnc
已加載插件:fastestmirror, refresh-packagekit, security
設置安裝進程
Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com
* epel: mirrors.aliyun.com
* extras: mirrors.aliyun.com
* updates: mirrors.aliyun.com
再次檢查是否安裝上
[root@opman ~]# rpm -qa |grep tigervnc
tigervnc-1.1.0-24.el6.x86_64
tigervnc-server-1.1.0-24.el6.x86_64
啓動vnc,首次會生成/root/.vnc/xstartup 文件,後面要配置相關參數
[root@opman ~]# vncserver
You will require a password to access your desktops.
Password:
Verify:
Passwords don't match - try again
Password:
Verify:
xauth: file /root/.Xauthority does not exist
New 'opman:1 (root)' desktop is opman:1
Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/opman:1.log
vim /root/.vnc/xstartup
#twm & //註釋該行
gnome-session & //添加該行 如果爲KDE桌面,則修改爲:startkde &
啓動服務,發現報錯,需要修改配置文件
[root@opman ~]# /etc/init.d/vncserver start
正在啓動 VNC 服務器:no displays configured [失敗]
vim /etc/sysconfig/vncservers ;添加末尾3行;作用是設定vnc用戶和對應界面的設置。我設置了兩個用戶分別是redhat 和root
最後啓動vncserver 並設置爲開機啓動,執行以下
# service vncserver start
# chkconfig vncserver on
檢查vnc服務的端口
[root@opman ~]# netstat -tunlp |grep vnc
tcp 0 0 0.0.0.0:5801 0.0.0.0:* LISTEN 3744/Xvnc
tcp 0 0 0.0.0.0:5802 0.0.0.0:* LISTEN 4481/Xvnc
tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 3744/Xvnc
tcp 0 0 0.0.0.0:5902 0.0.0.0:* LISTEN 4481/Xvnc
tcp 0 0 0.0.0.0:6001 0.0.0.0:* LISTEN 3744/Xvnc
tcp 0 0 :::6001 :::* LISTEN 3744/Xvnc
查看vnc 進程
[root@opman ~]# ps -ef |grep vnc
root 3744 1 0 16:56 pts/0 00:00:00 /usr/bin/Xvnc :1 -desktop opman:1 (root) -httpd /usr/share/vnc/classes -auth /root/.Xauthority -geometry 1024x768 -rfbwait 30000 -rfbauth /root/.vnc/passwd -rfbport 5901 -fp catalogue:/etc/X11/fontpath.d -pn
root 3754 3753 0 16:56 pts/0 00:00:00 vncconfig -iconic
root 4481 1 0 17:09 pts/0 00:00:00 /usr/bin/Xvnc :2 -desktop opman:2 (root) -httpd /usr/share/vnc/classes -auth /root/.Xauthority -geometry 800x600 -depth 32 -rfbwait 30000 -rfbauth /root/.vnc/passwd -rfbport 5902 -fp catalogue:/etc/X11/fontpath.d -pn -nolisten tcp
root 4492 4490 0 17:09 pts/0 00:00:00 vncconfig -iconic
root 5090 4787 0 17:25 pts/0 00:00:00 grep vnc
用vncview 連接測試效果:
發現連接超時,在一切都正常的情況下,關閉防火牆。
service iptables stop
[root@opman .vnc]# service iptables stop
iptables:將鏈設置爲政策 ACCEPT:nat mangle filter [確定]
iptables:清除防火牆規則: [確定]
iptables:正在卸載模塊: [確定]
[root@opman .vnc]#
再次連接,ip+:2(ip + 端口)
