如何重新启动scrapyd守护程序？ [英] How do I restart the scrapyd daemon?

问题描述

我已经完全按照文档。现在，我已经更改了 /etc/scrapyd/conf.d/000-default 中的一些配置变量。

I've installed the scrapyd daemon on an EC2 server exactly as described in the documentation. Now I've changed some of the configuration variables in /etc/scrapyd/conf.d/000-default.

如何做我不敢承认那些变化？我以为它涉及到重新启动守护程序，但是我找不到如何重新启动该守护程序的良好指导。

How do I get scrapyd to recognize those changes? I assume it involves restarting the daemon, but I can't find any good guidance on how to do so.

一个复杂的因素：我排队等待一堆爬网， d宁愿不失去他们。我认为scrapy知道如何退出并恢复正常运行，但是此功能没有充分的文档说明。

One complicating factor: I have a bunch of crawls queued up, and I'd rather not lose them. I think scrapy knows how to quit and resume them gracefully, but this feature isn't well-documented. Any guidance?

推荐答案

事实证明这很简单。

像这样杀死进程：

kill -INT $(cat /var/run/scrapyd.pid)

然后像这样重新启动它：

Then restart it like this:

/usr/bin/python /usr/local/bin/twistd -ny /usr/share/scrapyd/scrapyd.tac -u scrapy -g nogroup --pidfile /var/run/scrapyd.pid -l /var/log/scrapyd/scrapyd.log &

据我所知，两个命令都必须以root用户身份运行。

As far as I can tell, both commands need to be run as root.
