如何在后台运行太阳黑子重新索引为每四个小时 [英] how to run sunspot reindex in background for every four hours

问题描述

我要执行耙太阳黑子：重新索引RAILS_ENV =为每四个小时生产指挥。要做到这一点我一直在使用shell编程写简单的bash脚本。我将在终端成功运行，但如果我想在crontab中运行它，然后它不工作。它现在用的操作系统是CentOS的。

I want to execute rake sunspot:reindex RAILS_ENV=production command for every four hours. To achieve this i have written simple bash script using shell programming. I will run successfully in terminal but if i tried to run it in crontab then it is not working. Operating system which am using is centos.

下面是我的bash脚本code

Here is my bash script code

#!/bin/bash
#export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin
export PATH=/usr/local/rvm/gems/ruby-1.9.2-p290/bin:/usr/local/rvm/gems/ruby-1.9.2-p290@global/bin:/usr/local/rvm/rubies/ruby-1.9.2-p290/bin:/usr/local/rvm/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin:
echo "started"
cd /var/www/html/spotchase2
pwd
source /usr/local/rvm/environments/ruby-1.9.2-p290
bundle install
if [ "$?" = 0 ]; then
    echo `date`
fi
source /usr/local/rvm/environments/ruby-1.9.2-p290
#/usr/local/rvm/gems/ruby-1.9.2-p290/bin/rake sunspot:reindex RAILS_ENV=production
rake sunspot:reindex RAILS_ENV=production
if [ "$?" = 0 ]; then
    echo "complete"
fi

请帮我解决这个问题。

修改

我重定向输出一个文本文件中。在该文本文件正在逐渐才开始，捆绑安装和日期。我没有得到完整的消息，所以我才知道，它不工作并在该文本文件我没有得到任何错误。

I am redirecting the output one text file. In that text file am getting only started, bundle install and date. Am not getting complete message, therefore i came to know that it is not working and am not getting any error on that text file.

请帮我解决这个问题。

推荐答案

通常情况下，我使用每当宝石来处理这样的事情。我没有写一个bash脚本，耙剧本是好的就够了。 每当将生成的crontab正确的语法。

Usually, I use the whenever gem to handle something like this. I don't have to write a bash script, a rake script is okay enough. Whenever will generate the correct syntax for crontab.

在我的项目，我有几个剧本需要在后台运行所有的时间。这里是产生contab文件的命令。

In my project, I have several script that need to be run in background all the time. Here is the command to generate contab file.

whenever --update-crontab --set environment=production --load-file config/schedule_client.rb --user ubuntu

和它会产生弄成这个样子。

And it will generate into something like this.

0 2 * * * /bin/bash -l -c 'source /home/ubuntu/.rvm/scripts/rvm && cd /var/www/yoolk_statistics_api && RAILS_ENV=production bundle exec rake statistics:generate_clienst --silent >> log/client.log 2>&1'

要确保我的crontab总是工作，我将输出重定向到日志文件，这样我可以看到它的运行与否。在我的Ubuntu的服务器，我通常检查 syslog文件进行调试。

To make sure my crontab always work, I redirect the output to the log file so that i can see it's running or not. In my ubuntu server, I usually check the syslog file for debugging.
