redis cluster transaction

One, the company is now using the cluster scheme (REDIS+SENTINEL)Monitoring a Redis cluster together with multiple Sentinel detects that Master is not available and polls to determine if master needs to switch. Sentinel detects each other (by writing information in the co-detected master), Sentinel only needs to config

This article original from the http://blog.csdn.net/voipmaker reprint indicate the source. The purpose of the redis cluster is to achieve horizontal data scaling. By storing a piece of data in multiple machines, the database size, bandwidth, and computing capacity can be scaled horizontally. There are roughly three data sharding (cluster) methods: (1) impleme

This article mainly introduces the method of Laravel framework to realize Redis cluster, briefly analyzes the function setting steps, related operation skill and matters needing attention of Redis database cluster in Laravel framework, and needs friends to refer to This paper describes the method of implementing

Redis Study Notes (7)-cluster client (jedis) code example, redisjedis In the previous section, I learned how to build a cluster and operate on the redis-cli terminal. However, a more common scenario is to read and write the cluster in the program code, this requires

In-depth understanding of the use of Spring Redis (II), RedisTemplate transaction support, serialization, redisredistemplate In the previous article, we explained the basic usage of RedisTemplate, obtained the connection through RedisCallback, and then operated Redis. Most of the online tutorials are similar. This is similar to the executeWithNativeSession method

In the previous blog, we discussed how to implement caching in spring boot using Redis. But the database is clearly a single point is not enough, then how to use the Redis database to do the cache cluster it. Let's look into it today. Redis supports Master-slave (master-slave) mode, where

I spent a lot of time looking for a way to push the newly developed code into the production system to be able to 0 downtime and 0 impact on the use of the user.My idea is to use the cluster to do this, by notifying the load Balancer Nginx, remove the Tomcat node in the cluster, and then upgrade the application on Tomcat, and then notify the load Balancer Nginx to reload the Tomcat node. Do this in turn to

Therefore, in order to avoid this phenomenon, we bind the session by setting cookie informationhttpd Server configuration:cattomcat-proxy.confheaderadd set-cookie "routeid=.%{balancer_worker_route}e;path=/" env=BALANCER_ROUTE_CHANGED #设置cookie信息 Tomcat Host Configuration:Vim server.xml Similar modifications are made to the TOMCATB host.This will enable

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 sti
