Install Nginx Web server on CentOS 8 for Odoo 15 

Create a new configuration file for odoo.

Step 3:- sudo vim /etc/nginx/conf.d/odoo.conf

Modify this configuration snippet to fit your setup.

# Odoo Upstreams
upstream odooserver {
 server 127.0.0.1:8069;
}

server {
    listen 80;
    server_name erpcall.com;
    access_log /var/log/nginx/odoo_access.log;
    error_log /var/log/nginx/odoo_error.log;


    # Proxy settings
    proxy_read_timeout 720s;
    proxy_connect_timeout 720s;
    proxy_send_timeout 720s;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Real-IP $remote_addr;

    # Request for root domain
    location / {
       proxy_redirect off;
       proxy_pass http://odooserver;
    }

    # Cache static files
    location ~* /web/static/ {
        proxy_cache_valid 200 90m;
        proxy_buffering on;
        expires 864000;
        proxy_pass http://odooserver;
    }

    # Gzip
    gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
    gzip on;
}

Replace erpcall with your domain name, then validate Nginx configuration file.

$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

If all looks good, restart Nginx.

sudo systemctl restart nginx
