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

We know that the most important feature of the second kill system is the instantaneous high concurrency and high traffic volume system. We also want to make sure it's high availability.Here we develop a second-kill system using the Python Django Integrated Redis Sentinel (Sentinel) cluster.Redis Sentinel (Sentinel) clusterRedis Sentinel provides high availability for Redis clusters. In fact, this means that

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

---restore content starts---Redis SentinelSentinel (Sentinel) is a tool for monitoring the Master state in a Redis cluster, which has been integrated into the redis2.4+ versionFirst, Sentinel role:1): Master Status Detection2): If Master is abnormal, the master-slave switch is performed, one of the slave as master and the previous master as the Slave3): After the

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
