Ubuntu 16.04 - Nginx Laravel 500 HTTP错误

Question

I'm trying to startup a Laravel project through nginx but I'm stuck at the HTTP 500 error. I tried sudo chmod 777 -R storage also tried with 755 . Have already user php artisan cache:clear . Here is my 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;
    }
}

In my /var/log/nginx/error.log I get the error

2018/03/06 20:33:16 [error] 4090#4090: *10 FastCGI sent in stderr: "PHP message: PHP Parse error: syntax error, unexpected '?', expecting variable (T_VARIABLE) in /home/enthys/workspace/CodeBattles/vendor/symfony/finder/Comparator/NumberComparator.php on line 42 PHP message: PHP Fatal error: Exception thrown without a stack frame in Unknown on line 0 PHP message: PHP Parse error: syntax error, unexpected '?', expecting variable (T_VARIABLE) in /home/enthys/workspace/CodeBattles/vendor/symfony/finder/Comparator/NumberComparator.php on line 42 PHP message: PHP Fatal error: Exception thrown without a stack frame in Unknown on line 0" while reading response header from upstream, client: 127.0.0.1, server: cbattles.com, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/run/php/php7.0-fpm.sock:", host: "cbattles.com"

I had the same problem. I am not sure about all the specifics, but you need to update php to version 7.1+

I updated php to 7.2 on Ubuntu 16.04 this way:

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

Then removed the old version of php

sudo apt purge php7.1*

Then updated /etc/php/7.2/cli/php.ini file by setting

cgi.fix_pathinfo=0

Then:

sudo systemctl restart php7.1-fpm.service

Next step is to update /etc/nginx/sites-available/example.com file by setting the right version of fpm sock:

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

Finally restarting nginx:

sudo systemctl restart nginx.service
