It has been several months since reids was studied and used. I have summarized a lot of documents and related materials. In the next time, I will share some relevant materials, this article also describes how to use it in our applications. The following is an introduction to redis (refer to redis. io ): I. Use of things 1. Redis transactions start with the MULTI

Redis + keepalived master-slave cluster construction and failover Design ideas:When Master and Slave are working normally, master is in charge of the service, Slave is responsible for standby; When Master hangs up, Slave is normal, Slave takes over the service while shutting down the master-slave copy function; When Master returns to normal, the data is synchronized from Slave , after synchronizing the dat

Copy these jars to the Lib directory of Tomcat.Configure your Commons-pool, Jedis, and Tomcat versions in Tomcat-redis-session-manager Build.gradle and rebuild the project to build the results Tomcat-redis-session-manager-1.2.jar copied to the Tomcat Lib dire

Springboot redis (single-host/cluster), springbootredisPreface Redis has done so much to use in the project. Here, let's take a look at the usage of the standalone version and the cluster version in springboot. In this example, I will also post the Jedis version for comparison. 　　Standalone Edition 1. pom. xml 2. app

ObjectiveThere are so many redis in front of you to use in the project.Here, to see separately, stand-alone version and the cluster version in the use of springboot. Inside, I will also post the Jedis version, as a comparison.　　Stand-alone version1. Pom.xmlHttps://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-redis -Dependency> g

Precautions:1. If you are building a cluster using the REDIS-TRIB.RB tool, do not configure the password before the cluster is built, and set the password by the config set + config rewrite command on a per machine basis.2. If the password is set for the cluster, then both Requirepass and Masterauth need to be set, oth

start as the slave node for data synchronization. 3. and so on Both master and slave are DownMachine status: 1. This problem is not planned and is generally not considered. 2. Scheduled restart: save dump master database data through O M before restart. Pay attention to the sequence: 1. Shut down all redis on one of the machines, so that the master node is switched to another machine (deployed on multiple instances, where both the master and s

Redis's current support for transactions is relatively straightforward, and redis guarantees that commands in a client-initiated transaction can be executed consecutively without inserting other client commands; When a client initiates a multi command in a connection, The connection goes into the transaction context, and the subsequent commands are not executed i

Twemproxy is a proxy server that can be used to reduce the number of connections opened by the memcached or redis server.The following article describes how to deploy a redis cluster using twemproxy in the laravel project. The sample code in this article is very detailed, for more information, see the preface. twemproxy is a
