有一台云服务器，下载sqlmap运行报错：
python sqlmap.py missing one or more core extensions ('gzip', 'ssl', 'sqlite3', 'zlib')
最初我以为服务器有问题，就没管，因为其它服务器正常，就用其他的了。
今天，不小心又去那台机器执行了sqlmap，又继续报错。我一想，既然碰上了，还是解决下吧。
服务器装了三个版本python，首先确认有是哪个问题版本，发现是2.7.9。
root [~] python
python python2 python2.6 python3 python3.4
root [~] python -V
Python 2.7.9
python python2 python2.6 python3 python3.4
root [~] python -V
Python 2.7.9
然后，提示说缺失库，那么就逐个查看下到底缺少哪个。
root [~] python
Python 2.7.9 (default, Aug 31 2016, 22:04:01)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gzip
>>> import ssl
>>> import zlib
>>> import sqlite3
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named sqlite3

安装sqlite3，重新编译一遍python吧。
root [~] yum install sqlite-devel
root [~] ./configure --enable-loadable-sqlite-extensions
root [~] make
root [~] make install
root [~] ./configure --enable-loadable-sqlite-extensions
root [~] make
root [~] make install
至此，这台机器的sqlmap终于可以用了。
不过很遗憾，目标网站未发现sql注入，哈哈哈。
