說在前面的話
1、在kali中metasploit默認使用postgresql作為它的數據庫；
想要開啟metasploit服務首先得打開postgresql數據庫，
命令如下：（或者：/etc/init.d/postgresql start）;
因為在kali中所有的服務都不是默認開機自啟的，
所以想要開機自啟，命令如下：update-rc.d postgresql enable。
2、初次使用數據庫服務時需初始化，以便創建系統默認的數據庫及數據庫用戶；
命令如下：msfdb init（默認創建的數據庫名：msf，msf_test;用戶名：msf；口令默認為空）
3、接下來就是啟動metasploit的時候了；
在kali2.0之后，只需啟動msf控制台即可；
命令如下：msfconsole。
（kali2.0之前的命令是這樣的：service metasploit start；對於2.0之后不管用）
問題詳情
msf > db_status [*] postgresql selected, no connection msf >
運行 service Metasploit start 無任何反應，提醒報錯：
Failed to start metasploit.service: Unit metasploit.service failed to load: No such file or directory.
解決辦法
對於命令解釋
msfdb init # initialize the database
msfdb reinit # delete and reinitialize the database
msfdb delete # delete database and stop using it
msfdb start # start the database
msfdb stop # stop the database
root@kali:~# msfdb reinit Creating database user 'msf' 為新角色輸入的口令: 再輸入一遍: Creating databases 'msf' and 'msf_test' Creating configuration file in /usr/share/metasploit-framework/config/database.yml Creating initial database schema root@kali:~# msfdb start root@kali:~# msfconsole .~+P``````-o+:. -o+:. .+oooyysyyssyyssyddh++os-````` ``````````````` ` +++++++++++++++++++++++sydhyoyso/:.````...`...-///::+ohhyosyyosyy/+om++:ooo///o ++++///////~~~~///////++++++++++++++++ooyysoyysosso+++++++++++++++++++///oossosy --.` .-.-...-////+++++++++++++++////////~~//////++++++++++++/// `...............` `...-/////...` .::::::::::-. .::::::- .hmMMMMMMMMMMNddds\...//M\\.../hddddmMMMMMMNo :Nm-/NMMMMMMMMMMMMM$$NMMMMm&&MMMMMMMMMMMMMMy .sm/`-yMMMMMMMMMMMM$$MMMMMN&&MMMMMMMMMMMMMh` -Nd` :MMMMMMMMMMM$$MMMMMN&&MMMMMMMMMMMMh` -Nh` .yMMMMMMMMMM$$MMMMMN&&MMMMMMMMMMMm/ `oo/``-hd: `` .sNd :MMMMMMMMMM$$MMMMMN&&MMMMMMMMMMm/ .yNmMMh//+syysso-`````` -mh` :MMMMMMMMMM$$MMMMMN&&MMMMMMMMMMd .shMMMMN//dmNMMMMMMMMMMMMs` `:```-o++++oooo+:/ooooo+:+o+++oooo++/ `///omh//dMMMMMMMMMMMMMMMN/:::::/+ooso--/ydh//+s+/ossssso:--syN///os: /MMMMMMMMMMMMMMMMMMd. `/++-.-yy/...osydh/-+oo:-`o//...oyodh+ -hMMmssddd+:dMMmNMMh. `.-=mmk.//^^^\\.^^`:++:^^o://^^^\\`:: .sMMmo. -dMd--:mN/` ||--X--|| ||--X--|| ........../yddy/:...+hmo-...hdd:............\\=v=//............\\=v=//......... ================================================================================ =====================+--------------------------------+========================= =====================| Session one died of dysentery. |========================= =====================+--------------------------------+========================= ================================================================================ Press ENTER to size up the situation %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%% Date: April 25, 1848 %%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%% Weather: It's always cool in the lab %%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%% Health: Overweight %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%% Caffeine: 12975 mg %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%% Hacked: All the things %%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Press SPACE BAR to continue Validate lots of vulnerabilities to demonstrate exposure with Metasploit Pro -- Learn more on http://rapid7.com/metasploit =[ metasploit v4.12.41-dev ] + -- --=[ 1597 exploits - 912 auxiliary - 274 post ] + -- --=[ 458 payloads - 39 encoders - 8 nops ] + -- --=[ Free Metasploit Pro trial: http://r-7.co/trymsp ] msf > db_status [*] postgresql connected to msf msf >
則，可以成功！
