how to detect failure and auto restart celery worker

由 只愿长相守 提交于 2021-02-05 08:35:59
问题 I use Celery and Celerybeat in my django powered website. the server OS is Ubuntu 16.04. by using celerybeat, a job is done by a celery worker every 10 minutes. sometimes the worker shuts down without any useful log messages or errors. So, I want to find a way in order to detect status (On/Off) of celery worker (not Beat), and if it's stopped, restart it automatically. how can I do that? thanks 回答1: In production, you should run Celery, Beat, your APP server etc. as daemons [1] using

Audio through Cron Job

由 |▌冷眼眸甩不掉的悲伤 提交于 2021-02-04 20:59:19
问题 Does anyone know why audio wouldn't run through a cron job even though it runs perfectly fine when run through the command line. I have a python script that plays audio through a bluetooth speaker and when I run it on the command line (python helper.py) it plays fine, but running it through cron doesn't seem to work. Extra details: I am doing this on a Raspberry Pi that I have connected to a bluetooth speaker. I have a display connected to the raspberry pi (not doing it headless but that is

Is it possible to set a cron job or bash script to run X minutes from now?

问题 I understand I can set a cron job to run every 5 minutes with crontab -e by adding a line such as: */5 * * * * /path/to/script.sh . Is it possible to get the system time in minutes using date +"%M" for example, and then set a cron job to run at date +"%M" plus 5 minutes? I know I can get date +"%M" + 5 via the following process: $ MIN=`date +"%M"` $ export MIN $ expr $MIN + 5 Is it possible to use this to set a cron job or script to run at "current time in minutes" plus "X minutes"? I could

Google App Engine - Securing url of cron python

由 孤人 提交于 2021-02-04 06:24:07
问题 I'm a newbie to google app engine. I want the security restriction for url of cron so that it shouldn't be accessible by url directly. For this I've already read the docs and some of Q&As ([Google app engine: security of cron jobs). I implemented the login : admin solution suggested in this link. But I failed to implement security as self.request.headers.get('X-AppEngine-Cron') is always None , whether it is cron or accessed via url directly. So I don't know from where is the request coming

写在前面的话： 最近在看一本书，叫效率读书，其中讲述了两种思维，一种是发散性思维，一种是专注性思维，当我们在专注做一件事的时候，其实能持续的时间不是很长，大约在25分钟左右，如果时间过长，那么就会消耗很大，这个时候可以想想其他的事来分散一下注意力，也就是使用发散性思维，一般我是洗个澡，感觉洗了之后，思维比较清晰，各位也可以试试。 1、 前言 在操作系统中，存在着各种各样的事件，那么用什么来记录这些事件发生的时间和相关信息呢？那么就会用日志系统 rsyslog （ RHEL6.X ）。 2 、 日志系统 在 RHEL5.X 的时候，使用的服务如下所示： [root@testDB ~]#ps -ef|grep -E "syslogd|klogd" （ RHEL5.X 记录日志信息服务 ） root 2994 1 0 Sep06 ? 00:00:01 syslogd -m 0 （ 记录非内核产生的信息 ） root 2997 1 0 Sep06 ? 00:00:00 klogd -x （ 记录 kernel 产生的信息 ） 在 RHEL6.X 的时候，使用的服务如下所示： [root@rsyncserverscripts]# ps -ef|grep rsyslogd （ RHEL6.X 记录日志信息服务 ） root 1662 1 0 01:17 ? 00:00:00 /sbin

周一早上刚到办公室，就听到同事说有一台服务器登陆不上了，我也没放在心上，继续边吃早点，边看币价是不是又跌了。 不一会运维的同事也到了，气喘吁吁的说：我们有台服务器被阿里云冻结了，理由：对外恶意发包。 我放下酸菜馅的包子，SSH 连了一下，被拒绝了，问了下默认的 22 端口被封了。 让运维的同事把端口改了一下，立马连上去，顺便看了一下登录名 ：root，还有不足 8 位的小白密码，心里一凉：被黑了！ 查找线索 服务器系统 CentOS 6.X，部署了 Nginx，Tomcat，Redis 等应用，上来先把数据库全备份到本地，然后 Top 命令看了一下，有 2 个 99% 的同名进程还在运行，叫 gpg-agentd。 Google 了一下 GPG，结果是： GPG 提供的 gpg-agent 提供了对 SSH 协议的支持，这个功能可以大大简化密钥的管理工作。 看起来像是一个很正经的程序嘛，但仔细再看看服务器上的进程后面还跟着一个字母 d，伪装的很好，让人想起来 Windows 上各种看起来像 svchost.exe 的病毒。 继续排查： ps eho command -p 23374netstat -pan | grep 23374 查看 pid：23374 进程启动路径和网络状况，也就是来到了图 1 的目录，到此已经找到了黑客留下的二进制可执行文件。 接下来还有 2 个问题在等着我
