Tengo que configurar un servidor NGINX para poder equilibrar la carga de 2 o más sitios web https.
Escribí este código:
user nginx;
#worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
# sendfile on;
#tcp_nopush on;
# keepalive_timeout 65;
upstream servers_mito {
least_conn;
#server 10.200.0.43:801 max_fails=3 fail_timeout=30s;
server 10.200.0.43:443 max_fails=3 fail_timeout=30s;
#server 10.200.0.70:801 max_fails=3 fail_timeout=30s;
server 10.200.0.141:443 max_fails=3 fail_timeout=30s;
}
server {
#listen 80;
listen 443 ssl;
#ssl on;
ssl_certificate /etc/nginx/ssl/proxy1/server.crt;
ssl_certificate_key /etc/nginx/ssl/proxy1/server.key;
ssl_dhparam /etc/nginx/ssl/dhparam.pem;
server_name proxy1;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';
# access_log logs/domain2.access.log main;
location / {
proxy_pass https://servers_mito;
proxy_max_temp_file_size 0;
#proxy_set_header Host $host;
#proxy_set_header X-Real-IP $remote_addr;
#proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_ssl_server_name on;
}
location /nginx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
# allow 10.200.0.111;
allow 10.5.1.101;
deny all;
}
}
#location / {
# root /usr/share/nginx/html;
# index index.html index.htm;
# }
}
Los 2 servidores que estoy usando en este ejemplo son: 10.200.0.43 --> Spacewalk 10.200.0.141 --> Ansible
Si navego por esos sitios directamente, no hay problemas, los sitios están bien y son navegables. Si paso por NGINX los sitios están incompletos y no funcionan: inútiles, inutilizables, como se puede ver en las imágenes:

Este es el archivo de acceso:

Mientras que el error.log:

¿Puedes decirme qué estoy haciendo mal?
ps: si redirecciono en http funciona bien
Agregué esas líneas en el bloque http, pero lamentablemente nada cambió:

¿Crees que es correcto poner el número de puerto en el parámetro del servidor?
upstream servers_mito {
least_conn;
#server 10.200.0.43:801 max_fails=3 fail_timeout=30s;
server 10.200.0.43**:443** max_fails=3 fail_timeout=30s;
#server 10.200.0.70:801 max_fails=3 fail_timeout=30s;
server 10.200.0.141**:443** max_fails=3 fail_timeout=30s;
}
Y luego escribe httpsen el bloque de ubicación?
location / {
proxy_pass https://servers_mito;
proxy_max_temp_file_size 0;
Respuesta1
Debe establecer explícitamente el client_max_body_sizeparámetro en 0(ilimitado) en lugar del valor implícito de 1M:
http {
. . . . .
client_max_body_size 0;
client_body_timeout 180;
send_timeout 180;
proxy_send_timeout 180;
proxy_read_timeout 180;
. . . . .
