NGINX 404 - 反向代理

Question

以下是我在/conf.d

下的nginx反向代理的文件（default.conf）

server {
            listen 80 default_server;
            listen [::]:80 default_server ipv6only=on;

            root /usr/share/nginx/html;
            index index.html index.htm;

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

            location / {
                    proxy_pass http://www.paypal.com;
                    # First attempt to serve request as file, then
                    # as directory, then fall back to displaying a 404.
                    try_files $uri $uri/ =404;
                    # Uncomment to enable naxsi on this location
                    # include /etc/nginx/naxsi.rule
            }

            location /abc/{
                    proxy_set_header Host $host;
                    proxy_pass http://www.google.com;
                    # First attempt to serve request as file, then
                    # as directory, then fall back to displaying a 404.
                    try_files $uri $uri/ =404;
                    # Uncomment to enable naxsi on this location
                    # include /etc/nginx/naxsi.rule
            }

            location /xyz/{
                    proxy_set_header Host $host;
                    proxy_pass http://www.youtube.com;
                    # First attempt to serve request as file, then
                    # as directory, then fall back to displaying a 404.
                    try_files $uri $uri/ =404;
                    # Uncomment to enable naxsi on this location
                    # include /etc/nginx/naxsi.rule
            }

当我直接点击我的ip时，我被重定向到paypal但是当我点击 ip / abc 或 / ip / xyz 时，我得到了404
