python实现备份gitlab版本库并更改文件名

脚本的功能是实现备份gitlab版本库，并修改备份后的文件名，成功后发送邮件至相关负责人，脚本如下：

#!/usr/bin/env python
# -*- coding:utf-8 -*-


import time
import os
import commands
import subprocess
import smtplib
from email.mime.text import MIMEText
from email.utils import formataddr


class Svnbackup(object):
    '''
    svn svnbackup and save api for thi class
    '''

    def __init__(self, *arg):
        pass

    def sendmail(self, *arg):
        # mail content
        msg = MIMEText(arg[0], 'plain', 'utf-8')
        # maill address
        msg['From'] = formataddr(["SVN邮件提醒", '发件人邮箱'])
        # receive maill address
        msg['To'] = formataddr(['运维组邮箱', '收件人邮箱'])
        # mail topic
        msg['Subject'] = arg[1]

        # The mail SendServer
        server = smtplib.SMTP("smtp.163.com", 25)
        server.login("发件人邮箱", "发件人邮箱密码")
        server.sendmail('发件人邮箱', ['收件人邮箱', ], msg.as_string())
        server.quit()

    def runback(self):
        # del old version for the svn in the backsvn server
        starttime = time.time()
        back_status = subprocess.call(
            'cd /home/git/gitlab && PATH=/usr/local/bin:/usr/bin:/bin bundle exec rake gitlab:backup:create RAILS_ENV=production CRON=1 >/dev/null 2>&1',
            shell=True)
        endtime = time.time()

        # cost how many seconds
        costtime = (endtime - starttime)

        str_time = str(endtime).split('.')[0]

        float_time = float(str_time)

        ltime = time.localtime(float_time)

        timestr = time.strftime("%Y-%m-%d %H:%M:%S", ltime)

        mail_contentinfo = '%s 总耗时:%d秒 结束时间:%s' % ('研发源gitlab(172.16.50.44)备份成功,请确认!', costtime, timestr)
        mail_error_contentinfo = '%s ' % ('研发源SVN(172.16.50.44)备份失败,请联系SA刘辉煌!')
        if os.path.exists("/home/git/gitlab/tmp/backups/%s_gitlab_backup.tar" % (str_time)):
            os.rename("/home/git/gitlab/tmp/backups/%s_gitlab_backup.tar" % (str_time),
                      "/home/git/gitlab/tmp/backups/%s_gitlab_backup.tar" % (timestr))

        if back_status == 0:
            self.sendmail('%s' % mail_contentinfo, 'Gitlab备份成功!')
        else:
            self.sendmail('%s' % mail_error_contentinfo, 'Gitlab备份失败')

    def runserver(self):
        self.runback()


if __name__ == '__main__':
    backupsvn = Svnbackup()
    backupsvn.runserver()
    # backupsvn.modify_name()

 运行结果如下：
