按照默認(rèn)配置文件配置：
<pre>

You should look at the following URL's in order to grasp a solid understanding

of Nginx configuration files in order to fully unleash the power of Nginx.

http://wiki.nginx.org/Pitfalls

http://wiki.nginx.org/QuickStart

http://wiki.nginx.org/Configuration

Generally, you will want to move this file somewhere, and start with a clean

file but keep this around for reference. Or just disable in sites-enabled.

Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

Default server configuration

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;

# 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;//這個(gè)配置有問(wèn)題，出現(xiàn)無(wú)法獲$_SERVER['PHP_SELF']

    # 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;
            include fastcgi.conf;
            include fastcgi_params;

}

# 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/example.com;

index index.html;

location / {

try_files $uri $uri/ =404;

}

}

</pre>
這里root /var/www/html;

配置好重啟nginx
<pre>
nginx -s reload
</pre>
今天遇到一個(gè)奇怪問(wèn)題，配置一直不生效，所有文件都一直顯示404頁(yè)面

最后查了很久發(fā)現(xiàn)：
root /var/www/html;的文件夾沒(méi)有讀寫權(quán)限，最后設(shè)置為777權(quán)限才得以顯示，當(dāng)然不是全部子文件都需要777權(quán)限

希望能幫助更多的人解決這些坑，節(jié)省寶貴的時(shí)間。
