php - 在Ubuntu中使用nginx和php7.0-fpm的Laravel 5.4的502错误网关

我在Laravel 5.4服务器中安装了Ubuntu 16.04和nginx的php7.0-fpm应用程序，它提供了

502 Bad Gateway

Nginx virtualhost配置，

server {
    listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default ipv6only=on; ## listen for ipv6

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

    # Make site accessible from http://localhost/
    server_name localhost;

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

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

尝试了以下方法，但仍然无法正常工作，

将fastcgi_pass unix:/var/run/php7.0-fpm.sock;更改为fastcgi_pass 127.0.0.1:9000;
将try_files $uri $uri/ /index.php?$query_string;更改为try_files $uri $uri/ /index.php$is_args$args;
每次更改后重新启动服务，

service nginx restart
service php7.0-fpm restart

我只能使用此配置访问主路由，

server {
        listen   80; ## listen for ipv4; this line is default and implied
        #listen   [::]:80 default ipv6only=on; ## listen for ipv6

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

        # Make site accessible from http://localhost/
        server_name localhost;

        location / {
                try_files $uri $uri/ =404;
        }

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        }

        location ~ /\.ht {
                deny all;
        }
}

最佳答案

使用默认的基于php的配置更新一行，

server {
        listen   80; ## listen for ipv4; this line is default and implied
        #listen   [::]:80 default ipv6only=on; ## listen for ipv6

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

        # Make site accessible from http://localhost/
        server_name localhost;

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

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        }

        location ~ /\.ht {
                deny all;
        }
}

在这里将try_files $uri $uri/ =404;更改为try_files $uri $uri/ /index.php?$query_string;
