Haproxy configuration for Server Load balancer and haproxy configuration for Server Load balancerCommon Open-Source Software load balancers include Nginx, LVS, and Haproxy. Comparison of three major software load balancers (LVS Nginx VS Haproxy) I. LVS:1. Strong load resistance. Strong load resistance and high performa

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 d

combinations of policies, namely the third. The SSL connection is terminated at the Server Load balancer, adjusted as needed, and then acts as a new SSL connection proxy to the backend server. This may provide maximum security and the ability to send client information. The cost of doing so is more CPU power consumption and slightly more complicated configuration. The policy you select depends on your needs and application requirements. The SSL termi

configuration file needs to be created manually)Add:on UNIX class operating systems, Rsyslog is widely used in system logs . Rsyslog log messages can be either recorded in a local file or sent over a network to a server receiving a syslog. The server receiving the Syslog can store the syslog messages of multiple devices uniformly, or parse the contents of them to do the corresponding processing. The common application scenarios are network management tools,

Haproxy compared to the use of LVS is much simpler, functional aspects are also very rich. Currently, Haproxy supports two main proxy modes: "TCP" is also 4 layers (mostly for mail servers, internal protocol communications Servers, etc.), and 7 tiers (HTTP). In 4-tier mode, Haproxy only forwards bidirectional traffic between the client and the server. In 7-tier m
