1. 自动脚本ssh登陆

2. 执行原目录下的stop.sh文件，完成shutdown程序

3. 把原程序拷贝一份作为备份

4. 把本地新的程序通过scp上传到运行目录下

5. 执行start.sh

6. 执行tail，获取最新的日志打印

#!/usr/bin/python# -*- coding: utf-8 -*-import tracebackimport paramikofrom scp import SCPClientdef main():    ssh = paramiko.SSHClient()    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())    key = paramiko.RSAKey.from_private_key_file('F:\pub.key')    ssh.connect(hostname='111.111.111.111',                port=22,                username='root',                pkey=key)    scp = SCPClient(ssh.get_transport())    scp.put('./ssh_upload.py', '/root/ssh_upload.py')    scp.get('/root/ssh_upload.py', './ssh_upload.py.2')    _, stdout, _ = ssh.exec_command("tail -n 20 /var/log/mylog/access.log")    tail_logs = ''.join(stdout.readlines())    scp.close()    ssh.close()    print tail_logsif __name__ == '__main__':    try:        main()    except:        print traceback.format_exc()
