First, in the work because to use the Tomcat cluster deployment, this time involves the session sharing problem, mainly has three kinds of solutions:1. Use database to store session2. Use cookies to store session3. Use Redis to store sesssionSecond, this article mainly talk about the 3rd scenario, that is, using Redis to store Session,github already have the Open

On an article to tell you the installation of Nginx, then this article for you to talk about Nginx+tomcat to achieve load balance. First of all, why use Ngnix to do load balancing, in fact, the most famous for the load balance is F5, F5 is in the hardware facilities, often tens of thousands of, hundreds of thousands of, millions of, for the general small companies, this is a lot of overhead, so can try to use software, or use software, Although the effect will be somewhat poor, but still can pla

Nginx+tomcat+redis Configure session sharing and load balancing Using Nginx as a front-end server, the required session is deposited into the Redis, and the session can be taken from the Redis when one of Tomcat hangs. There are two options here. Scenario One: Use Tomcat-redis-seesion-manager to put the jar package in

Because of the need to use the Bulk Insert feature in the project, it was found on the web that Redis Bulk Insert can be efficiently inserted using pipeline, the sample code is as follows:String key = "key"new Jedis ("xx.xx.xx.xx"= jedis.pipelined (); list// data lists to be inserted for (String data:mydata) { p.hset (key, data);} P.sync (); Jedis.close ();However, the problem is that the Redis used on t

WIN 10:i5 4440, 8GBTest the transaction speed of RedisThe Redis watch mechanism implementation transaction is an optimistic locking form (which should be a spin lock). For scenarios where concurrency is not high, you can conserve CPU resources (lightweight locks). However, when the competition is intense, the probability of failure is greatly increased, and the r

Recently in learning Redis, we deployed a master-slave replication and multi-master multi-slave Redis cluster, however PHP or node is generally a single point, ask how to use PHP and node to do cluster connection, which involves some transactions. Reply content: Recently in learning

server downtime, need to get a cache cluster to avoid this situation.See there is a classic words to describe the occurrence of the outage and not let the user feel, equivalent to "flying aircraft for an engine" but also to let users feel no aircraft shaking, that is, no matter how the background changes in the situation, the user interface for the front-end user experience is better.In the system optimization scheme, we should consider the cache fir
