It is obtained by the Fermat theorem. For prime p, a ^ P = a (mod P), but for some non-prime p, A relatively small value may satisfy a ^ P = a (mod p). If yes, p is the Pseudo Prime Number Under Condition, ask if p is the Pseudo Prime Number of Condition.
Idea: first use Miller Robin to determine whether P is a prime number. If not, judge whether a ^ P = a (mod P) is true.

Haproxy configuration file is divided into two parts, the first part is the global configuration segment (global setting), the second part is the Agent configuration segment (Proxies). The global configuration segment sets some of the features of the haproxy operation, which are primarily related to process management and security directives, performance-tuning directives, and debug-related directives. And
First, HAProxyHardware-based load balancing devices: F5,BIG-IP, etc.Software-based load balancing products: Haproxy,lvs,nginx, etc.In the software load balancing product, it is divided into system-based soft load implementation and soft load implementation based on third-party software, and LVs is a kind of soft load based on system implementation. HA Proxy is a soft load balancer based on third-party application1.
