. Lvs scheduling algorithms are very important and you must be familiar with them. Have a detailed explanation on the official website: http://zh.linuxvirtualserver.org/ There are 10 Load Scheduling Algorithms for IPVS: Round Robin) Weighted Round call (Weighted Round Robin) Least Link (Least Connections) Weighted Least Connections) Locality-Based Least Connections) Locality-Based Least Connections with Replication) Destination Hashing)

LVS's working mechanism and scheduling algorithm have been recorded in my previous articles. See hereThe working mechanism of LVS is similar to iptabls. Some work in the user space (ipvsadmin) and some work in the kernel space. user space: used to define some load balancing objects and policies, for example, load the persistent connection to port 80 of the TCP protocol, or

This article describes how to configure Simple Server Load balancer on Docker. The host machine is Ubuntu14.04.2LTS, two CentOS containers, Nginx for the host machine, and tomcat 7 for the two containers. The architecture is as follows: the principle of this solution is to map the host machine port and the docker container port (that is, a port accessing the host machine will be mapped to the corresponding

it to Listener. If you have configured the Remote_listener parameter, the pmon process not only registers the load information to the local Listener, but also registers the Listener of other instances. With the pmon automatic registration mechanism, the Listener of each node in the cluster can master the load information of all nodes. When a client request is received, the connection is allocated to the in

Record Server Load balancer web Service requests based on DNS As a forum site: There are two types of data to be processed:1. structured data, such as user names and user comments, can be stored in relational databases. 2. unstructured data, such as attachments uploaded by users. Stored in the file system. Forum architecture: Use two httpd servers to serve users' access requests. Use the record of DNS for c
