我正在尝试将我的本地 nginx 服务器部署到公众。nginx 服务器作为我的node express 应用程序的反向代理运行,该应用程序也在端口 3000 上本地运行。因此,我创建了一个从 /etc/nginx/sites-available/express 到 /etc/nginx/sites-enabled/express 的符号链接,所以我的配置文件称为 express,看起来像这样。
/etc/nginx/sites-enabled/ express
upstream express_servers{
server 127.0.0.1:3000;
}
server {
listen 80;
location / {
proxy_pass http://express_servers;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
我已经从启用站点的文件夹中删除了默认文件,并且我没有更改我的 nginx.conf 文件,看起来像这样
/etc/nginx/ nginx.conf
user www-data;
worker_processes auto;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}
http {

# server_names_hash_bucket_size 64;
# server_name_in_redirect off;

##
# Virtual Host Configs
##
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
#mail {
# # See sample authentication script at:
# # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
#
# # auth_http localhost/auth.php;
# # pop3_capabilities "TOP" "USER";
# # imap_capabilities "IMAP4rev1" "UIDPLUS";
#
# server {
# listen localhost:110;
# protocol pop3;
# proxy on;
# }
#
# server {
# listen localhost:143;
# protocol imap;
# proxy on;
# }
#}
我还使用 ufw(简单防火墙)更改了我的防火墙设置,以允许 http 访问(尤其是 nginx)。我的 ufw 状态如下所示:
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), disabled (routed)
New profiles: skip
To Action From
-- ------ ----
80/tcp (Nginx HTTP) ALLOW IN Anywhere
80 ALLOW IN Anywhere
80/tcp (Nginx HTTP (v6)) ALLOW IN Anywhere (v6)
80 (v6) ALLOW IN Anywhere (v6)
当我使用 wrk 或 loadtest(npm) 运行负载测试时,一切似乎都正常。例如
wrk -t12 -c50 -d5s http://192.168.178.57/getCats/eng
所以在本地我可以访问 nginx 服务器,但是当我尝试使用我的手机(3G/4G)从公共访问服务器时,我无法访问服务器。我到底错过了什么?
编辑:我试图通过http://PUBLIC_IP_ADDR/getCats/eng访问服务,而不是本地地址。
