把kali的軟件源寫進了ubunt的軟件源
第一步
（此源為1.0版本，不適用於現在2.0版）阿裡雲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
修改軟件更新源配置文件：
vim /etc/apt/sources.list
將新的Kali源粘貼進去，同時將官方源用#號注釋掉。
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數據庫，連接數據庫要這樣
sudo -s #切換到root用戶
su postgres #切換到postgresql，實際上已經進入了數據庫管理了
然後
createuser msf -P -S -R -D #創建用戶
createdb -O msf msf #創建數據庫
exit
exit
然後在metasploit的安裝目錄：/usr/share/metasploit-framework下新建database.yml文件寫入以下信息
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 #連接數據庫
這樣數據庫就成功連接上了
msf > db_status
[*] postgresql connected to msf
至此，msf成功安裝上並且已經連上數據庫
