为了要在VPC的CentOS7系统中使用firefox首先需要安装图形界面VNC,按一下操作进行安装:

首先安装VNC服务器:
    yum groupinstall -y xfce
    yum install -y tigervnc tigervnc-server
安装完成之后:运行桌面系统
/usr/bin/startxfce4
安装火狐浏览器
yum -y install firefox

启动VNC服务
[root@li1602-78 ~]# vncserver

You will require a password to access your desktops.

Password:  //设置远程登陆密码
Verify:        //确认远程登陆密码
Would you like to enter a view-only password (y/n)? n
xauth:  file /root/.Xauthority does not exist

New 'li1602-78.members.linode.com:1 (root)' desktop is li1602-78.members.linode.com:1

Creating default startup script /root/.vnc/xstartup
Creating default config /root/.vnc/config
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/li1602-78.members.linode.com:1.log
好了,可以使用WIN版本 的tigerviewer连接了
