Re: NGINX load balancing - Proxy

February 15, 2022 10:18AM
Hi Francis,
Thanks for the reply and willingness to help me.

[root@proxy conf.d]# cat teste.conf
upstream webgateway {
server 192.168.239.151:9090;
server 192.168.239.152:9090;
}

server {
listen 9191;
proxy_pass webgateway;
}
[root@proxy conf.d]#

I cannot start NGINX.

Feb 15 01:56:24 proxy.lab.local systemd[1]: Starting The nginx HTTP and
reverse proxy server...
Feb 15 01:56:24 proxy.lab.local nginx[12274]: nginx: [emerg] "proxy_pass"
directive is not allowed here in /etc/nginx/conf.d/teste.conf:8
Feb 15 01:56:24 proxy.lab.local nginx[12274]: nginx: configuration file
/etc/nginx/nginx.conf test failed

Feb 15 01:56:24 proxy.lab.local systemd[1]: Failed to start The nginx HTTP

Feb 15 01:56:24 proxy.lab.local systemd[1]: Unit nginx.service entered
failed state.
Feb 15 01:56:24 proxy.lab.local systemd[1]: nginx.service failed.

I can only start NGINX if the file is as below.

upstream webgateway {
server 192.168.239.151:9090;
server 192.168.239.152:9090;
}

server {
listen 9191;

location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://webgateway;
}
}

The behavior on the client is the same.
I can load HTTP page and cannot HTTPS. On the Web Gateway, I view the
access logs with the client's IP.

In tests, I noticed that the "http_pass" below the "listen", I can't start
NGINX.
I had to also put it as "http" or http://webgateway;

If you don't put the parameters below, the proxy tries to load the page
http://webgateway.
proxy_set_header Host $host;

The parameter below registers the IP-Real of the client in the proxy.
proxy_set_header X-Real-IP $remote_addr;

Any tips? Thank You.
