nginx解析不到laravel/public里的index.php文件

Question

我将/etc/nginx/sites-available/default里面把root路径改成里/var/www/html/laravel/public了,但是运行结果是403,一开始以为是文件夹权限不够，照着网上说都storage和vendor都权限都可以读写里还是不行。 哪位大神帮我看看啊！
下面是我的nginx配置文件：

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

    # SSL configuration
    #
    # listen 443 ssl default_server;
    # listen [::]:443 ssl default_server;
    #
    # Note: You should disable gzip for SSL traffic.
    # See: https://bugs.debian.org/773332
    #
    # Read up on ssl_ciphers to ensure a secure configuration.
    # See: https://bugs.debian.org/765782
    #
    # Self signed certs generated by the ssl-cert package
    # Don't use them in a production server!
    #
    # include snippets/snakeoil.conf;

    root /var/www/html/laravel/public;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name _;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
    
    #   With php7.0-cgi alone:
    #    fastcgi_pass 127.0.0.1:9000;
    #   With php7.0-fpm:
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    location ~ /\.ht {
        deny all;
    }
}


# Virtual Host configuration for example.com
#
# You can move that to a different file under sites-available/ and symlink that
# to sites-enabled/ to enable it.
#
#server {
#    listen 80;
#    listen [::]:80;
#
#    server_name example.com;
#
#    root /var/www/html/laravel/public;
#    index index.html;
#
#    location / {
#        try_files $uri $uri/ =404;
#    }
#}

Answer 1

root下面一行的index后面加入一个index.php

Answer 2

问题找到了， 还是配置文件写错了

root /var/www/html/laravel/public;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html ;  ------>这里面要加上index.php

    server_name _;------------>这里要把域名写成127.0.0.1或者local    但是后来我测试里下用下划线 貌似也是可以正常显示的
