用easy_install pyOpenSSL安装的是pyOpenSSL-0.13版本，没安装成功，于是手动下载.011版本来进行安装。

[root@zxy-websgs opt]# wget http://launchpadlibrarian.net/58498441/pyOpenSSL-0.11.tar.gz -P /opt
[root@zxy-websgs opt]# tar zxvf pyOpenSSL-0.11.tar.gz 
[root@zxy-websgs pyOpenSSL-0.11]# python2.7 setup.py install

pyOpenSSL:http://launchpadlibrarian.net/58498441/pyOpenSSL-0.11.tar.gz

8.安装scrapy 1.0

[root@zxy-websgs pyOpenSSL-0.11]# easy_install -U Scrapy
