can't wget from my nginx web server - nginx

I configured an nginx webserver.
I created index.html inside ~/www/public
and I configured nginx to go for this location
like this
server {
listen 80;
server_name webserver1.net;
root /home/anasbarg/www;
index index.html;
}
of course I added this line to /etc/hosts:
192.168.8.101 webserver1.net
obviously, 192.168.8.101 is my nginx web server IP
the problem is, when I try to open from firefox it works fine.
However when I try wget command to download the index page the output is this:
--2017-10-22 08:19:30-- http://webserver1.net/
Resolving webserver1.net (webserver1.net)... 192.168.8.101
Connecting to webserver1.net (webserver1.net)|192.168.8.101|:80... connected.
HTTP request sent, awaiting response... 404 Not Found
2017-10-22 08:19:30 ERROR 404: Not Found.
so can any one explain it to me, I know that it's a basic question but I'm newbie :p so please I need your help.
thank you

rewrite is not working as desired for redirect URL in NGINX

I have an Nginx problem and after reading a lot and trying multiple combinations, I do not find the solutions to my problem.
I have a Jira server behind a reverse proxy using Nginx. My problem is that I want to have jira.mydomain.com as the default url but when using support.mydomain.com I want it to redirect to https://jira.mydomain.com/servicedesk/customer/portal/1 because is where the Service Desk. This is what I do not make.
The result that I have now is that both jira.mydomain.com and support.mydomain.com go to the same place which probably is the normal behavior and I do not know how to configure it but if anyone can help would be very appreciated.
Thanks to all of you and the hivemind.
This is what I have right now
/etc/nginx/conf.d/default.conf
upstream jira {
server jira_ip_adress:8081;
}
server {
server_name jira.mydomain.com;
server_name support.mydomain.com;
rewrite ^/support.mydomain.com https://jira.mydomain.com/servicedesk/customer/portal/1;
[...]
location / {
proxy_pass http://jira;
[...]
}
Nginx uses the server_name directive to match the domain name part of a URL. You need to use two server blocks, one for each of the domain names.
For example:
server {
server_name support.mydomain.com;
return 301 https://jira.mydomain.com/servicedesk/customer/portal/1;
}
server {
server_name jira.mydomain.com;
...
}
Obviously, if these are https services, you will need to add the appropriate listen statements to both server blocks.
Use nginx -T (uppercase T) to test the configuration file and view the entire configuration across all included files.
Many many thanks. I tried this yesterday but I had the next error when using nginx -T
nginx: [emerg] unexpected "E" in /etc/nginx/conf.d/default.conf:183
nginx: configuration file /etc/nginx/nginx.conf test failed
I have tried again after your help, and you spotted me in the right direction because today have been able to know what the error was telling to me and fixed.
So know, with your suggestion, is working like a charm.
Thanks a lot!

How to setup nginx for a Flask app on a server with Plesk installed

I want to deploy a little Flask webapp on a root cloud server with Plesk installed. I followed this tutorial as it uses Nginx and Gunicorn, like proposed by the developer of Flask: Miguel Grinberg.
The problem is that Plesk has a modified variant of nginx pre-installed named sw-nginx and I've absolutely no clue on how to implement that line of code:
server {
listen 80;
server_name my.subdomain.com;
location / {
include proxy_params;
proxy_pass http://unix:/var/www/vhosts/mydomain.com/my.subdomain.com/myproject/app.sock;
}
}
If I just put in in a .conf file, the configtest of Nginx fails:
$ nginx -t
nginx: [emerg] open() "/etc/nginx/proxy_params" failed (2: No such file or directory) in /etc/nginx/conf.d/myproject.conf:6
nginx: configuration file /etc/nginx/nginx.conf test failed
Maybe the syntax of the proxy_pass value is wrong (I tried many, here I put one of them), or maybe the proxy_pass param isn't supported or has to be implemented somewhere else?
PS: I also found this answer How to deploy Flask project on Plesk subdomain
But I read somewhere, that replacing sw-nginx by the standard nginx wouldn't be supported by Plesk. Don't want to break anything...
Thanks for your help.

Redirect default (80) port to 5000 - Flask + NGINX + Ubuntu

I'm successfully able to run a flask app on my IP:5000 path. A simple Hello World program that shows the output on my browser.
Now, what I would like to do is to configure NGINX with a proxy so that if I access only IP which apparently runs on a default port 80, it should navigate to port 5000 and show output of my application.
In other words...
This is working : IP:5000 -> Output = Hello world
This isn't working: IP -> This site can’t be reached
The server settings that I want to add would be something like this.
server {
listen 80;
server_name MY_IP;
location / {
proxy_pass http://127.0.0.1:5000;
}
}
However, I'm not sure where to add this? Should it be inside http block inside /etc/nginx/nginx.conf?
Updates: Based on the answers given below, I've managed to do the following.
I did restart nginx after this. However, I'm still facing the same issue. App works on IP:5000 but does not work on IP
The configuration you have mentioned should be in a separate file, assume example.com.conf under /etc/nginx/conf.d. You can put all the configuration in /etc/nginx/nginx.conf and it'll work, it's just that for readability we create separate configuration files which would be auto included when you add it inside conf.d.
Ok, the problem is fixed. As #senaps and #Mukanahallipatna had mentioned, I created the new configuration file under conf.d.
However, the most imp step that I was missing was this part mentioned in the below link.
It is recommended that you enable the most restrictive profile that will still allow the traffic you've configured. Since we haven't configured SSL for our server yet, in this guide, we will only need to allow traffic on port 80.
Reference Link
sudo ufw allow 'Nginx HTTP'
Now, everything is working fine.
Put the working blocks in a file with any_name.conf inside the folder named /etc/nginx/conf.d and it will be loaded automatically.
You will need to restart your nginx.
update:
What are you using to serve flask? if you are using uwsgi, then you should use configurations like this:
include uwsgi_params;
uwsgi_pass unix:path_to_your.sock;
Other options for uwsgi_pass are:
uwsgi_pass localhost:9000; #normal
uwsgi_pass uwsgi://localhost:9000;
uwsgi_pass suwsgi://[2001:db8::1]:9090; #uwsgi over ssl
If you are using gunicorn to serve your flask app, then your current configs should be fine, check if your app is running and if you can get your index page or not using 5000 port, then check for other problems. your configs looks good, maybe it's a problem on flask not being run?

How to manage many URLs / domains

I would like to get following situation:
I have domains: xxx.com zzz.com and yyy.com
I have one server: xxx.yyy.zz.qq
I would like to configure glassfish to start listening on port 80, and basing on the URL choose proper base catalog for my sites i.e.:
Scenario 1: Visitor is entering url xxx.com or www.xxx.com -> Glassfish receive request on port 80 and pick up catalog: ./glassfish4/myXXXcom/ where index.html for xxx.com is placed.
Scenario 2: Visitor is entering url zzz.com or www.zzz.com -> Glassfish receive request on port 80 and pick up catalog: ./glassfish4/anotherSite/ where index.html for zzz.com is placed.
What have I done:
Installed glassfish 4.1 on my server.
Changed A field of my domains to my server address.
Created virtual server:
glassfish4/bin/asadmin/create-virtual-server --hosts xxx.com xxx
Created http listener:
glassfish4/bin/asadmin create-http-listener --listeneraddress xxx.com --listenerport 80 --default-virtual-server xxx xxx
I think that I am doing something completely wrong here. How do I fix this problem?
If I understand correctly, what you need to do is, create two domains in glassfish or create a cluster and assign two instances of local glassfish instances. One running in port 28080 and another domain in 28081 and use nginx as the load balancer to forward the request to appropriate ports when requests comes from different domains. To make it clear, I am writing step by step
Create a new cluster in glassfish admin console
Create and assign a new local glassfish instance to cluster. This instance will be running in port 28080 and handles requests coming from example1.com
Create another glassfish domain 28081 as the port no for handling example2.com
Install nginx, this acts as proxy and forward request to appropriate
domains. Nginx will be running in port 80.
Start the cluster
Configure nginx as below. This is the crucial part
server {
listen 80;
server_name example1.com;
location / {
proxy_pass http://127.0.0.1:28080;
}
}
server {
listen 80;
server_name example2.com;
location / {
proxy_pass http://127.0.0.1:28081;
}
}
Start nginx
I hope you are familiar with creating clusters and domains in glassfish. If you are unfamiliar with creating clusters in commandline. Glassfish admin console is there, where you can achieve everything. If you need more info, please feel free to write in comments.

Using nginx to serve local files instead of remote files

Say I'm accessing www.mywebsite.com.
This website fetches the following asset:
http://www.mywebsite.com/styles/app.css
I want to access the website exactly as I normally would, with one exception:
Whenever my browser makes a request to /styles/app.css, instead of fetching it from http://www.mywebsite.com, I want to fetch it from http://localhost:3000/mywebsite/.
So instead it should be fetching:
http://localhost:3000/mywebsite/styles/app.css
Is this possible with nginx?
I tried to do it using the following server config:
{
...
server {
listen 80;
server_name mywebsite.com;
location /styles/ {
proxy_pass http://localhost:3000/mywebsite/styles/;
}
}
But even after restarting nginx (sudo nginx -s quit, sudo nginx), nothing seems to have changed.
When I browse to www.mywebsite.com/styles/app.css, I still get the same old app.css being retrieved from the server, rather than my local one.
