Overall design architecture diagram

1. Nginx load balancing

http { upstream tomcats { server localhost:19997; server localhost:19998; server localhost:19999; } server { listen 80; location / { proxy_pass http://shopservice.api; }}}Copy the code

2. Product service configuration requests shall not exceed three times within 60 seconds
