laravel - Laradock(docker)不断抛出http错误500

Question

无论我尝试什么，当我访问我的 docker-machine IP 时，我都会收到 HTTP 错误代码 500。

我通过 Docker 工具箱运行 laradock(操作系统:Windows 10)并运行默认虚拟机。我已经按照视频中的说明设置了 laradock。

我已成功将所需的文件夹安装到虚拟机中，并根据虚拟机中代码的位置更改了 docker-compose.yml:

这是我的 docker-compose.yml 文件:

当我登录工作区并更改文件时，它们会反射(reflect)到主机中，因此我在这方面很擅长。

这是我的工作容器中的文件夹结构(正如视频所示):

所有 nginx.conf 文件等都被加载到容器中，正如我从 docker exec -it 看到的到我的 nginx 容器中一样。

作为引用，这是我的 laravel.conf

server { listen 80 default_server; listen [::]:80 default_server ipv6only=on;

root /var/www/laravel/public;
index index.php index.html index.htm;

server_name laravel.dev www.laravel.dev;

location / {
     try_files $uri $uri/ /index.php$is_args$args;
}

location ~ \.php$ {
    try_files $uri /index.php =404;
    fastcgi_pass php-upstream;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

location ~ /\.ht {
    deny all;
}

}

和 nginx.conf:

user www-data; worker_processes 4; pid /run/nginx.pid;

events { worker_connections 2048; multi_accept on; use epoll; }

http { server_tokens off; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 15; types_hash_max_size 2048; client_max_body_size 20M; include /etc/nginx/mime.types; default_type application/octet-stream; access_log on; error_log on; gzip on; gzip_disable "msie6"; include /etc/nginx/conf.d/.conf; include /etc/nginx/sites-available/; open_file_cache max=100; }

daemon off;

这是我的 laravel 根目录的 .env 文件:

APP_ENV=local APP_DEBUG=true APP_KEY=SomeRandomString APP_URL=http://localhost

DB_CONNECTION=mysql DB_HOST=192.168.99.100 DB_PORT=3306 DB_DATABASE=homestead DB_USERNAME=homestead DB_PASSWORD=secret

CACHE_DRIVER=file SESSION_DRIVER=file QUEUE_DRIVER=sync

REDIS_HOST=192.168.99.100 REDIS_PASSWORD=null REDIS_PORT=6379

MAIL_DRIVER=smtp MAIL_HOST=mailtrap.io MAIL_PORT=2525 MAIL_USERNAME=null MAIL_PASSWORD=null MAIL_ENCRYPTION=null

我还通过登录工作区容器并键入以下内容来设置文件夹的权限:

chmod -R 777 storage bootstrap/cache

但我仍然在 docker-machine ip 上收到 http 500 错误。我错过了什么？

Answer 1

我发现的一个潜在问题是您在 .env 中使用服务主机(DB_HOST、REDIS_HOST)的 IP 地址。这些 IP 地址可能会更改，因此使用容器名称作为主机地址更安全。在您的情况下，您需要使用“DB_HOST=mysql”和“REDIS_HOST=redis”。

http 500 意味着您的 nginx 配置可能没有任何问题，听起来更像是 Laravel 配置问题。我建议您检查 Laravel 日志文件 (storage/logs/laravel.log) 以获取更多信息。
