如何使Laravel Queue系统在服务器上运行 [英] How to keep Laravel Queue system running on server

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

nohup-运行不受挂断影响的命令，并输出到非tty

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

nohup - run a command immune to hangups, with output to a non-tty

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.
