最近想持續監伺服器的測硬碟容量，但是又不想在伺服器上東搞西搞，發現python有個paramiko可以連線linux,

# -*- coding: utf-8 -*-
# @Author  : mlp
# @File    : linux_email.py
import paramiko,re,time,smtplib
import smtplib
from email.mime.text import MIMEText
from email.header import Header
# HostIP = 地址
# username = 登入名
# passwd = 密碼
#埠一般預設為22
 
def run(HostIP, username, passwd):
    try:
        ssh = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh.connect(HostIP, 22, username, passwd)

        #連線測試
        #ssh.exec_command('ls')
        #print(u"%s 連線成功"%HostIP)

        #執行命令獲取結果
 stdin, stdout, stderr = ssh.exec_command('df -h'
 
)

        #result = stdout.read().decode()
 err = stderr.read()
        result = stdout.read()
        ssh.close()
        #print(stdin, err)
        #print(stdout.read())
 aa = re.findall("[0-9]{1,2}%", result)
        #print result   #直接檢視伺服器返回結果
 if int(aa[0].strip("%")) >= 50:
            #print(u"************【注意】{0}伺服器硬碟容量目前已使用{1}************\n".format(HostIP, aa[0]))
 
            # 輸入Email地址和口令:
 from_addr = "[email protected]"
 password = "mlp123456"
 # SMTP伺服器地址:
 smtp_server = "smtp.163.com"
 # 收件人地址:
 to_addr = "[email protected]"

 msg = MIMEText(u"************【注意】{0}伺服器硬碟容量目前已使用{1}************\n".format(HostIP, aa[0]), 'plain', 'utf-8')
            msg['From'] = "mlp<********@163.com>"
 msg['To'] = "***<******@qq.com>"

 subject = u'【注意】硬碟容量預警'
 msg['Subject'] = Header(subject, 'utf-8')

            server = smtplib.SMTP(smtp_server, 25)  # SMTP協議預設埠是25
 server.set_debuglevel(1)
            server.login(from_addr, password)
            server.sendmail(from_addr, [to_addr], msg.as_string())
            print(u"郵件傳送成功")
            server.quit()

        else:
            print(u"{}硬碟容量目前已使用{}\n".format(HostIP, aa[0]))

    except Exception as ex:
        print "\tError %s\n" % ex

if __name__ == '__main__':
    print("--------------------------------------------------------------")
    print u"開始連線"+time.strftime(u"當前日期:%Y年%m月%d日 %H:%M:%S",time.localtime(time.time()))
    #把地址和密碼放在下面
    serverlist = {“***”：“******”}
    for hostip in serverlist:
        run(HostIP=hostip, username="root", passwd=serverlist[hostip])

ok，湊活能用
