Based on our current situation and requirements, after a brief comparison, our team decided to choose a fourth option Redis+sentinel to achieve dual-machine hot standby. preparatory work 1. Install redis-001

Some days ago, a classmate's computer was infected with a fierce virus and looked at me. The scene was very tragic: in the lower-right corner of the screen, undesirable advertisements, System icon changes, many programs are displayed on the computer, the CPU usage is 100%, and the mouse and keyboard are almost unusable.
The anti-virus process takes a long time, fr

The Redis Sentinel system is used to manage multiple Redis servers, performing three main tasks:1) Monitoring: Sentinel constantly check whether the master-slave server is operating properly;2) Reminder: When a Redis server problems, you can send notifications through the API;3) Automatic failover: When a primary server fails,
Comments: Mcafee, Norton, and Kaspersky are the three major antivirus software in the world. Its monitoring capabilities and protection rules are quite powerful, and it is the best of its kind of software. It is a soft M that I highly recommend.CAfee VirusScan8.5i + Patch5 + 5200 + integrated and optimized Anti Version Download

Redis Redundancy Scheme (keepalived, HAProxy, Redis Sentinel)
If you're looking for a redis redundancy solution, I've found the following scenario, and I think I can try this out.
"highly Available Redis Cluster | Simplicity is the keynote of all true elegance"
Initially, it was considered to be built using pacemaker, because the Redis author launched Sentinel's scenario, so this article uses the Sentinel
First, Protected-mode
By default, Redis node and Sentinel Protected-mode are yes, and if you want to connect a Redis cluster remotely from a remote connection, you need to modify the Protected-mode of Redis node and Sentinel to No, If you only modify Redis node, you will still not be able to use it from the remote Connection Sentinel, and the

2: Modify Redis.conf profile
A: Modify the service port number to ensure that the port number is unique

B: Add from configuration

The redis Server is a one-to-many architecture. The server uses the I/O multiplexing technology to process file events and processes requests from multiple clients in a single thread and single process. struct redisServer {// stores the list * clients;/* List of active clients * // linked list, and stores the list *
Jedis Shard Sentinel Connection Pool experiment 1. CauseAs is known to all, the Redis official Ha Tool Sentinel has been in existence for a long time, but it is puzzling that Jedis officials have been slow to update its connection pool. Until the latest version of 2.7.3 in the Maven library, only shard connection pooling or non-fragmented sentinel connection pool

Redis Sentinel FeatureRedis Sentinel is a set of distributed systems for managing Redis instances, with 3 main tasks to complete:1) Monitoring: Continuously monitor whether Redis master or slave instances are running as expected2) Notification: If the monitored Redis instance is running abnormally, Sentinel will notify the external (person or program) via API3
