我们先来说一种方法，直接从github来下载：

git clone --depth=1  git://github.com/rapid7/metasploit-framework metasploit

然后：

结果是这样的：

[email protected]:~/metasploit$ ls
app		    features			  msfconsole  script
CODE_OF_CONDUCT.md  Gemfile			  msfd	      scripts
config		    Gemfile.local.example	  msfrpc      spec
CONTRIBUTING.md     Gemfile.lock		  msfrpcd     test
COPYING		    HACKING			  msfupdate   tools
data		    lib				  msfvenom    Vagrantfile
db		    LICENSE			  plugins
documentation	    metasploit-framework.gemspec  Rakefile
external	    modules			  README.md

然后直接msfconsole就可以运行了。另外就是更新也在这里：msfupdate(执行的时候注意权限问题)

第二种方法：

首先我们来下载一下这个文件，并且保存的文件名称为msfinstall

curl https://raw.githubusercontent.com/rapid7/metasploit-omnibus/master/config/templates/metasploit-framework-wrappers/msfupdate.erb > msfinstall

结果是这样的：

[email protected]:/home/magic/tools/metasploit# curl https://raw.githubusercontent.com/rapid7/metasploit-omnibus/master/config/templates/metasploit-framework-wrappers/msfupdate.erb
#!/bin/sh

msfinstall

没错这个就是别人写好的下载脚本。你可以直接保存为msfinstall，然后赋予这个文件可执行权限就可以了。

然后来执行：

然后我们就可以运行metasploit了：
