如何使Laravel Queue系统在服务器上运行

问题描述

我最近设置了Laravel Queue系统.基本内容是cronjob，该命令调用将作业添加到队列的命令，并调用第二个发送电子邮件的命令.

当我SSH进入服务器并运行php artisan queue:listen时，系统正常工作，但是如果我关闭终端，则监听器将关闭，并且作业会堆积并排在队列中，直到我ssh重新进入并再次运行监听. /p>

使队列系统在后台运行而不需要通过ssh保持连接打开的最佳方法是什么?

我尝试运行php artisan queue:work --daemon，它完成了队列中的作业，但是当我关闭终端时，它关闭了连接和后台进程.

解决方案

正在运行

nohup php artisan queue:work --daemon &

将防止您注销时退出命令.

结尾的与号(&)导致进程在后台启动，因此您可以继续使用该Shell，而不必等待脚本完成.

请参见 nohup

这会将信息输出到运行命令的目录中名为nohup.out的文件中.如果您对输出不感兴趣，可以将stdout和stderr重定向到/dev/null，或者类似地，也可以将其输出到常规laravel日志中.例如

nohup php artisan queue:work --daemon > /dev/null 2>&1 &

nohup php artisan queue:work --daemon > app/storage/logs/laravel.log &

但是您也应该使用 Supervisord 之类的东西，以确保该服务保持运行并在崩溃/失败后重新启动.

I recently setup a Laravel Queue system. The basics are a cronjob calls a command which adds jobs to a queue and calls a second command which sends an email.

The system works when I ssh into my server and run php artisan queue:listen, but if I close my terminal the listener shuts down and the jobs stack up and sit in queue until I ssh back in and run listen again.

What is the best way to keep my queue system running in the background without needing to keep my connection open via ssh?

I tried running php artisan queue:work --daemon, and it completed the jobs in the queue, but when I closed my terminal it closed the connection and the background process.

解决方案

Running

nohup php artisan queue:work --daemon &

Will prevent the command exiting when you log out.

The trailing ampersand (&) causes process start in the background, so you can continue to use the shell and do not have to wait until the script is finished.

See nohup

This will output information to a file entitled nohup.out in the directory where you run the command. If you have no interest in the output you can redirect stdout and stderr to /dev/null, or similarly you could output it into your normal laravel log. For example

nohup php artisan queue:work --daemon > /dev/null 2>&1 &

nohup php artisan queue:work --daemon > app/storage/logs/laravel.log &

But you should also use something like Supervisord to ensure that the service remains running and is restarted after crashes/failures.
