Ubuntu 16.04 - Nginx Laravel 500 HTTP錯誤

Question

我正試圖通過nginx啟動一個Laravel項目，但我遇到了HTTP 500錯誤。 我試過sudo chmod 777 -R storage也嘗試用755 。 已經有用戶php artisan cache:clear 。 這是我的config /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我收到錯誤

我有同樣的問題。 我不確定所有細節，但你需要將PHP更新到7.1+版本

我通過這種方式在Ubuntu 16.04上將php更新到7.2：

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

然后刪除舊版本的PHP

sudo apt purge php7.1*

然后通過設置更新/etc/php/7.2/cli/php.ini文件

cgi.fix_pathinfo=0

然后：

sudo systemctl restart php7.1-fpm.service

下一步是通過設置正確版本的fpm sock來更新/etc/nginx/sites-available/example.com文件：

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

最后重啟nginx：

sudo systemctl restart nginx.service
