运行ansible前，会出现一下Warning。
[WARNING]: The version of gmp you have installed has a known issue regarding
timing vulnerabilities when used with pycrypto. If possible, you should update
it (i.e. yum update gmp).
解决方法：

cp /usr/lib64/python2.6/site-packages/pycrypto-2.6.1-py2.6-linux-x86_64.egg/Crypto/Util/number.py{,.bak}
perl -p -i -e "s/^(if _fastmath is not None .*:)/#\1/" /usr/lib64/python2.6/site-packages/pycrypto-2.6.1-py2.6-linux-x86_64.egg/Crypto/Util/number.py
perl -p -i -e "s/^(\s*_warn.*Not using mpz_powm_sec.*)/#\1/" /usr/lib64/python2.6/site-packages/pycrypto-2.6.1-py2.6-linux-x86_64.egg/Crypto/Util/number.py
