1.出现问题
安装后，到/metasploit/apps/pro/msf3目录，运行msfcli，但出现错误提示，意思是无法编译本地的一个模块。
查了下，发现是没有安装ruby1.9.1-dev，安装后，运行budle install仍然报错，错误提示变成缺少类库。
2.安装类库
于是逐个安装缺失的类库。安装记录如下，我的是安装这些后，成功运行msfconsole了。
sudo apt-get install ruby1.9.1-dev
bundle install
sudo apt-get install postgresql
sudo apt-get install ruby-all-dev
apt-cache search libpq
sudo apt-get install libpq-dev
apt-cache search pcap
sudo apt-get install libpcap-dev
apt-cache search libsqlite
sudo apt-get install libsqlite3-dev
bundle install
3.创建数据库
现在，工作已经基本就绪，但为了更好地发挥其性能，还是要对数据库进行基本设置。现在，msf只支持postgreSQL，这个 数据库的操作其mySQL有较大的不同。
下面是我在shell中的操作记录，目的在于建立一个名为msfbook的数据库，同时建立一个用户msf来操作该数据库：
23:42:47@~/Downloads$sudo -u postgres createuser --superuser msf //建立超级用户msf
[sudo] password for westnorth:
23:46:35@~/Downloads$sudo -u postgres psql //进入postgreSQL的shell
psql (9.3.4)
Type "help" for help.
postgres=# \password msf //给该用户赋予密码
Enter new password://用户msf的密码
Enter it again:
postgres=# \q
could not save history to file "/var/lib/postgresql/.psql_history": No such file or directory
23:47:13@~/Downloads$
23:47:26@~/Downloads$sudo -u postgres createdb -O msf msfbook //创建数据库msfbook，并将其所有者指定为msf
4.设置msf与数据库的连接
一般来说，设置数据库以写配置文件比较理想。配置文件编辑命令如下，将xx换成自己的安装目录：
sudo gvim ××/metasploit/apps/pro/msf3/config/database.yml
在其中设置数据库名与用户、密码后，就可使用db_connect命令连接数据库了。命令如下：
msf > db_connect -y config/database.yml
[*] Rebuilding the module cache in the background...
msf > db_status
[*] postgresql connected to msfbook
5.使用数据库
下面是在msf中使用数据库的例子：
msf > sudo nmap -Pn -sS -A -oX hosts.xml 192.168.1.0/24 ***将扫描结果写入hosts.xml
[*] exec: sudo nmap -Pn -sS -A -oX hosts.xml 192.168.1.0/24
