Ubuntu 16.04 - Nginx Laravel 500 HTTP 错误

Question

我正在尝试通过 nginx 启动一个 Laravel 项目，但我遇到了 HTTP 500 错误。我试过sudo chmod 777 -R storage 也试过755。已有用户php artisan cache:clear。这是我的配置/etc/nginx/sites-enabled/default

server {
    listen 80;
    listen [::]:80;

    server_name cbattles.com www.cbattles.com;

    root /home/enthys/workspace/CodeBattles/public;
    index index.php index.html index.htm;

    location / {
            try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass unix:/run/php/php7.0-fpm.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
    }
}

在我的/var/log/nginx/error.log 中出现错误

我遇到了同样的问题。我不确定所有细节，但您需要将 php 更新到版本 7.1+

我以这种方式在 Ubuntu 16.04 上将 php 更新为 7.2：

sudo add-apt-repository ppa:ondrej/php
sudo apt install php7.2 php7.2-common php7.2-cli php7.2-fpm

然后去掉旧版本的php

sudo apt purge php7.1*

然后通过设置更新/etc/php/7.2/cli/php.ini文件

cgi.fix_pathinfo=0

然后：

sudo systemctl restart php7.1-fpm.service

下一步是通过设置正确的 fpm sock 版本来更新 /etc/nginx/sites-available/example.com 文件：

fastcgi_pass unix:/run/php/php7.2-fpm.sock;

终于重启了nginx：

sudo systemctl restart nginx.service
