Security and technical architecture:

• RSA encryption protection: The system uses high-standard RSA encryption technology to ensure user data security.
• technology stack: Based on PHP8.1 and Swoole5 network driver engine, ensuring efficient operation and rapid response of the system.

System configuration requirements:

1. Low configuration requirements:

   • Two 4-core 8GB servers
   • Operating system: CentOS 7.9
   • Bandwidth: Exclusive 5M+
   • Depending on the number of trading pairs, the number of servers can be increased.

2. Recommended configuration:

   • Two 8-core 16GB servers
   • Operating system: CentOS 7.9
   • Bandwidth: Exclusive 5M+

Deployment steps and environment settings:

1. Install Pagoda environment, to ensure the stability of the server environment.
2. Install PHP8.1And configure the necessary extensions:
   • Redis、Fileinfo、GMP、Swoole5.0+
   • Modify the PHP configuration and remove all disabled functions.
3. Database and service settings:
   • Database: MySQL 8.x, Redis 5.x
   • CURL: Version 8.x or above.
4. Start the service:
   • Use commandnohup php -d swoole.use_shortname=’Off’ bin/hyperf.php start >/dev/null 2>&1 &Start the service.
   • Service stopped:ps -ef | grep -v grep | grep Exchange | awk '{print $2}' | xargs kill -9
   • Update currency prices:php -d swoole.use_shortname=’Off’ bin/hyperf.php load:currency(Service needs to be restarted).
   • Generate RSA key pair:php -d swoole.use_shortname=’Off’ bin/hyperf.php gen:key, the key is stored inconfigTable of contents.

Service configuration and deployment:

• Enter the server directory and edit.envConfiguration files for service deployment.

Security management of user private keys:

• Generate and properly keep the RSA key pair to ensure that the private key is safe and not stored on the server.
• The private key is used to view the address and private key on the user’s chain. To change the private key, the service needs to be restarted.

Nginx configuration:

• Configure multiple subdomains:
  • H5 domain name: h5.xxx.com
  • Official website domain name: web.xxx.com
