如何让nginx显示错误日志？
如何让nginx显示错误日志？
我正在使用docker开发我的项目，使用了一个安装了nginx的镜像，如果发生任何错误，我只能看到这个：
502 Bad Gateway nginx/1.4.6 (Ubuntu)
目前，唯一能看到发生了什么的方式是检查storage/logs，这样也可以，但是难道不能在浏览器中看到日志错误，而不仅仅看到502 Bad Gateway吗？
在我的.env文件中：
APP_ENV=local APP_DEBUG=true
有什么想法吗？

如果我的应用程序没有错误，我会在浏览器中正常看到它，只有当Laravel应用程序出现错误时，我才会看到502 Bad Gateway错误。
错误会是：

nginx配置：

listen 80 default_server;
root /share/public/;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ /index.php$is_args$args;

# pass the PHP scripts to FastCGI server listening on /var/run/php5-fpm.sock

}
nginx错误发生在PHP之中，因此你在浏览器中无法看到这些错误。
您可以在/var/log/nginx/文件夹中检查nginx日志以查找错误，并清空storage/logs文件夹，以确保其中没有新的错误。
一旦您修复了nginx错误，您可以根据https://stackoverflow.com/a/5438125/50475的说明，配置PHP将所有错误显示到浏览器中。
问题的出现原因：502 Bad Gateway错误是由于错误的web服务器配置造成的。您的请求由Nginx处理，但它无法将其重定向到PHP或Laravel。这个错误的原因很可能是在Nginx配置中缺少或错误的代理转发到PHP。
解决方法：这些错误只会记录在Nginx错误日志（/var/log/nginx/error.log）中，而不会记录在Laravel日志中，因为您的应用程序和PHP并未处理该请求。因此，以前提到的"当前唯一的方法是检查storage/logs，这是可以的"让我困惑了，但是一个错误的网关从来不会由PHP或Laravel处理，所以他永远不会在存储日志目录中看到任何问题的记录，相信我 😉
噢，好的，那样说得通。我忘记了应用程序中的这种异常会触发502错误。但是感觉Nginx的配置仍然不正确。您的代理的nginx配置是什么？您能贴出来吗？
