把kali的軟體源寫進了ubunt的軟體源
第一步
（此源為1.0版本，不適用於現在2.0版）阿里雲Kali源為：
deb http://mirrors.aliyun.com/kali kali main non-free contrib
deb-src http://mirrors.aliyun.com/kali kali main non-free contrib
deb http://mirrors.aliyun.com/kali-security kali/updates main contrib non-free

在2016.1版本kali-linux（也就是kali滾動更新版）更新慢解決辦法：
（此源為2.0版本）中科大kali滾動更新版源（即kali2.0源）
#kali官方源
deb http://http.kali.org/kali kali-rolling main non-free contrib
#中科大的源
deb http://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib

修改軟體更新源配置檔案：
vim /etc/apt/sources.list

將新的Kali源貼上進去，同時將官方源用#號註釋掉。
再:
    apt-get update & apt-get upgrade
    apt-get dist-upgrade
    apt-get clean
sudo apt-get install metasploit-framework
這樣就把神器msf成功裝上了，然後我進去發現沒有連上資料庫，連線資料庫要這樣
sudo -s        #切換到root使用者  
su postgres    #切換到postgresql，實際上已經進入了資料庫管理了
然後
createuser msf -P -S -R -D #建立使用者  
createdb -O msf msf        #建立資料庫  
exit
exit
然後在metasploit的安裝目錄：/usr/share/metasploit-framework下新建database.yml檔案寫入以下資訊
production:  
   adapter: postgresql  
   database: msf  
   username: msf  
   password:  
   host: 127.0.0.1  
   port: 5432  
   pool: 75  
   timeout: 5
 
然後進入msf
msf > db_connect -y /usr/share/metasploit-framework/database.yml #連線資料庫
這樣資料庫就成功連線上了
msf > db_status  
[*] postgresql connected to msf
至此，msf成功安裝上並且已經連上資料庫
