系统环境设置


> 开始阶段,首先,用vnc软件进行和服务器的连接



  • vnc软件提供桌面共享服务,是服务端! Server



    用户用的是vncviewver,是客户端Client



    属于C-S 模型 (即:客户端-服务端模型)

打开vnc:

Applications—–>internel——>vncviewer

输入服务器地址: 172.25.254.250:8

点击虚拟机:

root ——>not list——–>root 密码 ##以管理员进入

student ——–>student 密码 ##以student用户进入

打开命令行(Terminal:bash/shell):

1: Applications ——->Utilities ——–> Terminal ##进入到用户目录下

2 : 右键 ——-> Open in Terminal ##进入到用户桌面目录下

3 : 打开命令行后输入:


[kiosk@foundation77 Desktop]$ gnome-terminal


##再次打开命令行 进入到用户桌面目录下

    gnome-session-quit --force          // 退出虚拟机
    exit                                //退出命令行
    4)系统关机,重启
    重启
    reboot | init 6 |shutdown -r now
    关机
    poweroff | init 0 | shutdown -h now


tips:


Applications ———-> System Tools———>Settings——>Shortcuts

自己设置快捷键添加快捷方式

//可以添加的命令如:

gnome-session-quit   --force    //关闭虚拟机
gnome-terminal                  //打开命令行
gnome-control-center            //打开控制中心


虚拟机控制

[kiosk@foundation9 ~]$ rht-vmctl view desktop           ##显示desktop
Error: unable to view desktop - not currently running.  ##报错,未运行虚拟机
[kiosk@foundation9 ~]$ rht-vmctl start desktop          ##开启虚拟机
Starting desktop.
[kiosk@foundation9 ~]$ rht-vmctl view desktop 
[kiosk@foundation9 ~]$ rht-vmctl status desktop         ##查看虚拟机状态
desktop RUNNING
[kiosk@foundation9 ~]$ rht-vmctl poweroff desktop       ##关闭虚拟机
Powering off desktop..
[kiosk@foundation9 ~]$ rht-vmctl reset desktop          ##重置desktop虚拟机
Are you sure you want to reset desktop? (y/n) y         ##询问是否重置y表示yes

报错解释

[kiosk@foundation9 ~]$ rth-vmctl view desktop    
bash: rth-vmctl: command not found...            ##命令出错,未找到
[kiosk@foundation9 ~]$ rht-vmctl strt desktop
Error: bad option, strt                          ##选项出错

This utility manages the Red Hat Training supplied VMs on the local
hypervisor.

Usage: rht-vmctl [-q|--quiet] VMCMD VMNAME
       rht-vmctl -h|--help

  where VMCMD is one of:
    reset      - poweroff, return to saved or original state, start VMNAME
    view       - launches console viewer of VMNAME
    start      - obtain and start up VMNAME
    stop       - stop a running VMNAME
    poweroff   - if running, force stop VMNAME
    save       - stop, backup image, start VMNAME
    restore    - poweroff, restore image, start VMNAME
    fullreset  - poweroff, reobtain from server, start VMNAME (bad save/image)
    get        - if not here, obtain VMNAME from server
    status     - display libvirt status of VMNAME
[kiosk@foundation9 ~]$ rht-vmctl start 17-07            
Error: unrecognized VMNAME specified, 17-07.  ##名称出错,没有这个名称的虚拟机

linux中的快捷键 :




*

一个非常重要的键——tab键:

在系统中table键可以自动补齐存在的命令,文件名称和某些命令的参数

  a+TAB x2  显示系统中所有a开有的命令


**所以它合理的使用可以大幅度的提高工作效率!!!
