Dear Sir,

 

Dear sir,

So Do you need my vps information to check?
Thank you

 

Dear sir,

Code:

tcp        0      0 0.0.0.0:http            0.0.0.0:*               LISTEN      4463/nginx: master
tcp        0      0 0.0.0.0:webcache        0.0.0.0:*               LISTEN      4463/nginx: master
tcp        0      0 0.0.0.0:https           0.0.0.0:*               LISTEN      4463/nginx: master

i see webcache. i think it's using port 80...

 

Dear Sir,

Code:

[root@li1777-43 ~]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

 

Dear sir,

Code:

[root@li1777-43 ~]# netstat -plant | grep nginx
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      4249/nginx: master
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      4249/nginx: master
tcp        0      0 0.0.0.0:443             0.0.0.0:*               LISTEN      4249/nginx: master

 

Dear Sir,
I just disable "#include /usr/local/nginx/conf/conf.d/*.conf;" in nginx.conf.
then i use

Code:

netstat -plant | grep nginx

Output nothing

 

i know which file config use port 80, but i changed listen 8080 but i don't know why it's using 80

Code:

server {
            listen   8080;
            server_name csdldoanhnghiep.com;
            return 301 $scheme://www.doanhnghiep.com$request_uri;
       }

server {
  server_name csdldoanhnghiep.com www.doanhnghiep.com;
