配置虛擬機器

    1.
 
 下載virtualbox的yum源 請訪問http://www.92wiki.com

    切換到/etc/yum.repos.d/ 並下載 VirtualBox repo到當前目錄.

    [[email protected] ]# cd /etc/yum.repos.d/
    [[email protected] ]# wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo  

    2.確認當前源內容中gpgcheck is enabled (gpgcheck=1)並修正gpg key路徑: 想知道更多內容:

    [
 
[email protected] ]# cat virtualbox.repo
    [virtualbox]
    name=RHEL/CentOS-$releasever / $basearch - VirtualBox
    baseurl=http://download.virtualbox.org/virtualbox/rpm/rhel/$releasever/$basearch
    enabled=1
    gpgcheck=1
    gpgkey=http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc 

    * yum search virtualbox

    * yum install virtualbox-xxx

    * usermod -a -G vboxusers yzf

    * 安裝好windows之後，預設ctrl+F是全屏

    * 然後預設按住ctrl切換host(主機)
 

安裝chrome

    http://www.tecmint.com/install-google-chrome-on-redhat-centos-fedora-linux/

    * step1: vim /etc/yum.repos.d/google-chrome.repo, 新增下面內容

        ```
           [google-chrome]
           name=google-chrome
           baseurl=http://dl.google.com/linux/chrome/rpm/stable/$basearch
           enabled=1
           gpgcheck=1
           gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub
        ```

    * step2: yum info google-chrome-stable

    * step3: yum install google-chrome-stable --nogpgcheck (因為gpg驗證的網站被牆了)

    * step4: 輸入命令google-chrome & 開啟chrome瀏覽器, 如果是在root使用者下，會報錯。所以看step5

        ```
            報錯相關：
            [1:1:0106/102918:ERROR:nacl_fork_delegate_linux.cc(315)] Bad NaCl helper startup ack (0 bytes)
        ```

    * step5: http://superuser.com/questions/971922/google-chrome-on-a-fresh-centos-7-1-not-starting-up

    * 或者可以直接去：https://www.google.com/chrome/browser/desktop/index.html下載chrome，前提是要翻牆。

    * 由於chrome54後不再內建flashplayer，這裡有解決辦法:http://tieba.baidu.com/p/4844331767

 mkdir -p tools

4 進入到目錄 /usr/local/tools 中：
 cd tools/

5 下載 jdk-8u91-linux-x64.tar.gz：(任選一個)

 wget --no-check-certificate --no-cookies --header "Cookie: Oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u71-b14/jdk-7u71-linux-x64.rpm

 tar -zxvf jdk-8u91-linux-x64.tar.gz


7 返回到上一級並建立 /usr/local/jdk 目錄：

 cd ..
 mkdir -p jdk


8 進入到 tools 目錄後將 jdk1.8.0_91 移動到 jdk 目錄中：
