Question

我正在服务器上运行ubuntu 17.10，已经安装并正在运行nginx

sudo systemctl restart nginx

和

sudo /etc/init.d/nginx status

可以执行并返回运行状态

但是，当我访问我的IP：8080（因为我将8080放在nginx配置上）或我的IP：80（我刚刚尝试）或我的IP：8082（因为我在{{3上构建了我的有角度的前端和配置apiBaseUrl时） }}）显示

This site can’t be reached
ERR_CONNECTION_RESET

在Chrome和 safari can't open the page, ...because server where this page is located isn't responding在Safari上。

我试图检查防火墙：

sudo ufw status

它显示：

Status: active

8080/tcp (v6)              ALLOW       Anywhere (v6)

和其他检查：

netstat -natup | grep LISTEN

显示：

tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      -

tcp6       0      0 :::80                   :::*                    LISTEN      -                   
tcp6       0      0 :::86                   :::*                    LISTEN      -

和sudo netstat -tanpl|grep nginx显示：

tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      99228/nginx: master 
tcp6       0      0 :::8080                 :::*                    LISTEN      99228/nginx: master

这是我的/etc/nginx/sites-available/default文件内容：

> server {
>     listen 80 default_server;
>     listen [::]:80 default_server;
>  
>     root /var/www/html;
>     index index.html index.htm index.nginx-debian.html;
>  
>     server_name _;
>  
>     location / {
>         try_files $uri $uri/ /index.html =404;
>     } }

我已经通过ng build --prod构建了前端站点，并将生成的文件夹（位于“ dist”文件夹下）下的所有内容复制到/var/www/html/文件夹（其中也包含“ index.nginx-debian.html” “文件）

其他信息：我的后端在nodejs pm2上运行。在mongodb上运行的数据库。更新：根据需要我的nginx.conf文件：

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    gzip on;

    # gzip_http_version 1.1;

    ##
    # 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;
#   }
#}

我观察到的另一件事：如果我从服务器curl -I http://localhost:8080运行此命令，则会得到：

HTTP/1.1 200 OK
Server: nginx/1.14.0
Date: Fri, 31 May 2019 06:58:26 GMT
Content-Type: text/html
Content-Length: 700
Last-Modified: Fri, 31 May 2019 02:44:47 GMT
Connection: keep-alive
ETag: "5cf0951f-2bc"
Accept-Ranges: bytes

但是如果我用myserver IP替换localhost：

curl -I http://my.server.ip.address:8080

然后我得到了

curl: (7) Failed to connect to 13.67.51.66 port 8080: Connection timed out

我的服务器也使用Azure云服务，这会阻止ICMP，然后我不能使用IP从外部连接到我的服务器吗？那我该怎么办呢？

我期望从本地笔记本电脑尝试这些尝试之一，至少我可以获得： http://localhost:8082

但不是。

请问您知道有什么原因吗？我该怎么做呢？非常感谢你！

即使Nginx在Ubuntu上运行也无法访问默认页面
