说在前面的话

1、在kali中metasploit默认使用postgresql作为它的数据库；

　　想要开启metasploit服务首先得打开postgresql数据库，

　　命令如下：（或者：/etc/init.d/postgresql start）;

　　因为在kali中所有的服务都不是默认开机自启的，

　　所以想要开机自启，命令如下：update-rc.d postgresql enable。

2、初次使用数据库服务时需初始化，以便创建系统默认的数据库及数据库用户；

　　命令如下：msfdb init（默认创建的数据库名：msf，msf_test;用户名：msf；口令默认为空）

 

3、接下来就是启动metasploit的时候了；

　　在kali2.0之后，只需启动msf控制台即可；

　　命令如下：msfconsole。

　　（kali2.0之前的命令是这样的：service metasploit start；对于2.0之后不管用）

 

 

 

 

　　问题详情

msf > db_status[*] postgresql selected, no connectionmsf >

 

运行  service Metasploit start 无任何反应，提醒报错：Failed to start metasploit.service: Unit metasploit.service failed to load: No such file or directory.

 

 

 

解决办法

　　对于命令解释

　　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
