cron

问题 Hi so right now I have a basic cron that runs my stuff twice a day at 1 and 6. Something like: H 1,18 * * * The problem is I have like 100 things kicking off at this time which is clogging up my machine. I want to randomly generate a time once a day for each job to run. It's ok if 5-7 are going at once. So I guess my question is. For one is this possible? If so is there a best practice for this? I'm loading everything up in groovy so I was just thinking about generating a number between 1-24

问题 I am deploying my Laravel application to ElasticBeanstalk environment. I am trying to run a command in the Scheduling Task on the server. But it is not working. This is what I have done.

Then I tried two different approaches. First Approach: Using Laravel AWS Worker package , https://packagist.org/packages/dusterio

问题 Does any body know where is the STDOUT and STDERR of a normal crontab job output in CentOS? I checked the /var/log/cron file, but it only record the time and command of a cron job executed, no STDOUT or STDERR content found there. 回答1: Have a look on /etc/rsyslog.d/ there you should can change loglevel of cron . #cron.* /var/log/cron.log removing the # = maximum logging cron.err /var/log/cron.log only error log 来源： https://stackoverflow.com/questions/28067714/where-is-the-stdout-and-stderr

问题 Here issue in R scripts I am trying to understand how would here() work in a portable way. Found it: See what works later under Final answer - TL;DR - the bottom line, here() is not really that useful running a script.R from commandline. The way I understand it with help from JBGruber: here() looks for the root directory of a project (e.g., an RStudio project, Git project or other project defined with a .here file) starting at the current working directory and moving up until it finds any

问题 I have got a page which queues up emails in beanstalked. The script works as intended, the emails get fired when i have a queue listener, ie. php artisan queue:listen But when i remove the listener and add it to the crob job * * * * * /usr/bin/php /var/www/huge/artisan queue:listen The emails don't get fired. Any ideas? 回答1: Had this exact same issue the other day, you probably just need to cd in to the directory where Artisan is located first. Try the following: * * * * * cd /var/www/huge/ &

问题 i have a node(v0.7.3-pre) server with node-cron(0.3.2) and node-time(0.8.2): var cronJob = require('cron').CronJob; var cronJ = new cronJob({ cronTime: "00 29 16 6 * *", onTick: function() { console.log("Tick"); }, start:true, timeZone: "America/Los_Angeles" }); console.log(cronJ); it runs, but the Cron is allways working with the server time(UTC), and the returned cron is: { _callbacks: [ [Function] ], onComplete: undefined, cronTime: { source: '00 29 16 6 * *', zone: undefined, second: { '0
