Introduction to ACLs:The Haproxy ACL is used to make forwarding decisions based on the header of the request packet, the content of the response message, or other environmental state information, which greatly enhances its configuration flexibility. The configuration rule is usually divided into two steps, defining an ACL first, defining a test condition, and then executing a specific action when the condition is met, such as blocking the request or f

General Overview:keepalived is a software similar to the Layer3, 4 5 switch, which is what we normally call the 3rd, 4th, and 5th layers of exchange. The role of keepalived is to detect the state of the Web server, if a Web server freezes, or a work failure occurs, keepalived detects and rejects the failed Web server from the system. When the Web server is working properly, Keepalived automatically joins the Web server to the server farm, all of which are automatically completed without human i
