500 服务器错误:脚本头过早结束: [英] 500 Server error: Premature end of script headers:

问题描述

我有一个使用 solr 索引服务器的 php 网站，基于 CodeIgniter.

I have a website in php that works with a solr indexation server, based on CodeIgniter.

我们得到了很多新内容，所以我们刷新了数据库，并且不得不重新索引内容(大约 168,000 个元素).我创建了一个脚本来按 500 个切片对内容进行索引 - 脚本完成后，我们启动下一个索引.

We got a lot of new content, so we flushed the database, and had to reindex the content (about 168,000 elements). I created a script to index the contents by slices of 500 – when the script finishes, we launch the next indexing.

它在我的本地测试环境中运行良好，但在生产环境中出现 500 错误:

It works perfectly on my local test environment, but on production I get this 500 error:

[Thu Dec 02 ...] [error] [client IP] Premature end of script headers: index.php

在我的 php.log 中绝对没有任何内容，只有返回它的 apache error_log.我曾在网站的其他页面上看到它发生过一两次，但它是在编制索引期间发生的.

There is absolutely nothing in my php.log, just the apache error_log that returns it. I've seen it happen on other pages of the website once or twice, but it was during this indexing.

有什么想法吗?

推荐答案

此错误通常(有时)由 FcgidIOTimeout 指令(旧名称:IPCCommTimeout).

This error is usually (sometimes) caused by the FastCGI setup of the FcgidIOTimeout directive (old name: IPCCommTimeout).

即 IO 超时的秒数，默认为 40 秒.超时意味着

That is the number of seconds for IO timeout, default is 40 seconds. Timeout means that

FastCGI 应用程序必须在这段时间内开始生成响应.根据需要增加此指令以处理需要相对较长时间响应的应用程序."

您可以尝试将其放入 vhost.conf 来解决:

You can try to solve it putting this into your vhost.conf:

<IfModule mod_fcgid.c>
  # 5 minutes for IO timeout, default is 40 seconds
  FcgidIOTimeout 300
</IfModule>

您可以根据需要增加它，然后在重新索引过程完成后恢复原始值.

You can increase it as you need and then restore the original value once the reindexing process is complete.
