2019独角兽企业重金招聘Python工程师标准>>> 
【pre:】
CentOS release 6.10 |Python 2.6.6
step1:安装 git
#yum install git
step2:安装依赖
yum install gcc python-devel zlib-devel zlib openssl openssl-devel
setp3:pip安装(python2.6安装pip)
#wget https://bootstrap.pypa.io/2.6/get-pip.py
#python get-pip.py
step4:沙盒安装
#pip install virtualenv
step5:下载&安装python2.7
#wget https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tgz
# tar xvf Python-2.7.8.tgz
#cd Python-2.7.8
# ./configure --prefix=/usr/local/python/py278/ --with-zlib
# make && make install
step6:安装主程序依赖twist
#cd /opt
# virtualenv py278 --python=/usr/local/python/py278/bin/python2.7
# . py278/bin/activate
# wget https://files.pythonhosted.org/packages/0f/88/18bb0eddb483033e35b1b84bdf9de4cedb8906ece178e2d921451282b3c8/Twisted-14.0.2.tar.bz2
# tar -xvf Twisted-14.0.2.tar.bz2
# cd Twisted-14.0.2
#python setup.py install
step7:安装主程序
# pip install opencanary
修改配置文件
#vim /root/.opencanary.conf
修改sshd端口号位：8000
#vim /etc/ssh/sshd_config
重启sshd服务
#/etc/init.d/sshd start
step8:启动opencanaryd&验证
# opencanaryd --start
验证是否启动
# ps -ef|grep opencanary
step9:核实蜜罐是否生效
#telnet 192.168.213.130 22
查看日志
#vim /var/tmp/opencanary.log
{"dst_host": "192.168.213.130", "dst_port": 22, "local_time": "2018-09-12 15:27:02.657861", "logdata": {"SESSION": "1"}, "logtype": 4000, "node_id": "opencanary-1", "src_host": "192.168.213.1", "src_port": 58605}
step10:编写opencanary定时任务，并启动定时任务
* * * * * /root/opencanary/opencanary.sh
【编写opencanary.sh，并将此脚本放到定时任务中每分钟执行一次，对三次握手行为监控】

continuestep12:用nmap验证step10、step11联动效果
#nmap -sS 192.168.213.130 -p 22
当不启动cap.py脚本时，我们收不到报警邮件，启动后，在执行nmap扫描端口程序，则会收到报警信息。
