我得到这样的错误:

总是一样的。一个url重复使用逗号分隔。不知道是什么引起的。有人知道吗?

更新:另一个错误:

http request count is zero while sending response to client

这是配置。还有其他不相关的东西,但这部分是添加/编辑的

fastcgi_cache_path /var/nginx-cache levels=1:2 keys_zone=WORDPRESS:100m inactive=60m;

            #this should match value of "listen" directive in php-fpm pool
            server unix:/var/run/php5-fpm.sock;
    }

然后在服务器块中: 设置$skip_cache 0;

    # POST requests and urls with a query string should always go to PHP
    if ($request_method = POST) {
            set $skip_cache 1;

当前回答

Plesk指令

我把上面两个答案结合起来

在Plesk 12中,我让nginx作为反向代理运行(我认为这是默认的)。因此,当前顶部的答案不工作,因为nginx也作为代理运行。

我进入订阅|[订阅域]|网站和域(选项卡)|[虚拟主机域]| Web服务器设置。

然后在该页的底部,你可以设置附加nginx指令,我设置为上面两个答案的组合:

fastcgi_buffers         16  16k;
fastcgi_buffer_size         32k;
proxy_buffer_size          128k;
proxy_buffers            4 256k;
proxy_busy_buffers_size    256k;

其他回答

如果你使用Symfony框架: 在搞砸Nginx配置之前,先禁用ChromePHP。

1 -打开app/config/config_dev.yml

注释这些行:

#chromephp:
    #type:   chromephp
    #level:  info

ChromePHP将调试信息json编码在X-ChromePhp-Data头文件中,这对于使用fastcgi的nginx的默认配置来说太大了。

来源:https://github.com/symfony/symfony/issues/8413 # issuecomment - 20412848

我正在使用Symfony,它有一个很好的异常页面(当使用ErrorHandler时)。这将把异常的消息作为创建的响应的头。

vendor/symfony/error-handler/ErrorRenderer/SerializerErrorRenderer.php

头部被称为:X-Debug-Exception

所以要小心,如果你构造了一个非常大的异常消息,无论是nginx还是chrome (limit 256k)还是curl (~128kb)都不能显示你的页面,并且很难调试,输出这些大标题是什么。

我的建议是不要盲目地复制粘贴增加的缓冲区大小到你的nginx配置中,他们治标不治本。

我有这个错误,我找到了3种方法来修复它:

在.env: https://stackoverflow.com/a/69321273/13653732中设置shell_verbose =0或另一个< 3的值。在这种情况下,您将禁用PHP日志,但它们对开发和调试很有用。 fastcgi设置。在php.ini中Logging =0。与上述结果相同。 将Symfony从5.2更新到5.3。我认为旧版本在这方面有问题。

所有的PHP Symfony日志都被认为是Nginx的错误,但PHP工作正常。

我有Nginx 1.17, PHP 8.0.2, PHP- fpm, Symfony 5.2, Xdebug, Docker。

我尝试了新版本Nginx 1.21, PHP 8.0.14,但没有任何结果。这个问题不在于Apache。

我改变了Nginx的配置,但也没有任何结果。

对于Symfony项目,尝试将这一行添加到您的.env文件中:

SHELL_VERBOSITY=0

https://symfony.com/doc/current/console/verbosity.html

我将把它留在这里,因为我花了大量的时间在我的项目中调试这个,只有这个特定的解决方案100%适合我(出于正确的原因),我从未找到与这个主题相关的答案。也许有人会觉得有用。

在我们的例子中,我们得到了这个nginx错误,因为我们的后端生成了一个非常长的URL重定向响应:

HTTP/1.1 301 Moved Permanently 
Location: https://www.example.com/?manyParamsHere...

出于好奇,我们将这个大URL保存到一个文件中,它的大小为4.4 Kb。

在配置文件/etc/nginx/conf.d/some_site.conf中添加两行帮助我们修复了这个错误:

server {
    # ...
    location ~ ^/index\.php(/|$) {
        fastcgi_pass php-upstream;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        # Add these lines:
        fastcgi_buffer_size 32k;
        fastcgi_buffers 4 32k;
    }
}

在nginx官方文档中阅读更多关于这些参数的信息。
