怎么在linux上安装vnc

1.首先检查是否安装了VNC服务输入命令：rpm -qa | grep vnc

2.安装VNC，首次执行vncserver需要设置密码，可以创建多个桌面，执行多次vncserver命令即可。

[root@node04 ~]# yum install vnc vnc-server
[root@node04 ~]# yum install tightvnc-server

[root@node04 ~]# vncserver

3.配置防火墙，如果不配置防火墙，客户端VNC就没有办法连接到Linux。

[root@node04 ~]# iptables -I INPUT -p tcp --dport 5901 -j ACCEPT

[root@node04 ~]# iptables -I INPUT -p tcp --dport 5801 -j ACCEPT

在这里是添加了两个桌面，桌面与端口对应关系是：桌面1对应5901，桌面2对应5801，也可以自己设置。

4.配置桌面客户端

[root@node04 ~]# vi /root/.vnc/xstartup

#!/bin/sh

unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
/etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r HOME/.Xresources ] && xrdbHOME/.Xresources ] && xrdbHOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title “$VNCDESKTOP Desktop” &
gnome-session &
# Assume either Gnome or KDE will be started by default when installed
# We want to kill the session automatically in this case when user logs out. In case you modify
# /etc/X11/xinit/Xclients or ~/.Xclients yourself to achieve a different result, then you should
# be responsible to modify below code to avoid that your session will be automatically killed
if [ -e /usr/bin/gnome-session -o -e /usr/bin/startkde ]; then
vncserver -kill $DISPLAY
fi

此步骤前提是Linux中安装了gnome桌面环境,查看是否安装Gnome桌面环境

[root@node04 ~]# yum grouplist

There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
