Introduction There is a need to use Redis at work recently, so I have a whim to write a Java client. After two days of effort, the client is now basically molded. Unfortunately, because of the number of REDIS commands, the LZ also needs to slowly expand it to support more commands. Share This article only two purpos
number of a node is 6379, then it communicates with other nodes with a port number of 16379. The communication between nodes uses a special binary protocol.For the client, the entire cluster is considered to be a whole, and the client can connect to any node to operate, just as with a single Redis instance, when the client
Using Python to connect to Redis, you need to install Python and redis-py, and in CentOS as an example, introduce Redis-py's client environment setup.No. 0 Step: Prepare for workHuawei Cloud purchased 1 ECS (I chose CentOS 6.3), a distributed cache instance (DCS for Redis),

1. Installation
Redis-py is the Python interface to the Redis Key-value database, installed as follows, and we'll talk about Hiredis this library
Copy Code code as follows:
$ sudo pip install Redis
$ sudo pip install Hiredis

types support Push/pop, Add/remove, and intersection-set and difference sets, and richer operations, and these operations are atomic. Based on this, Redis supports sorting in a variety of different ways. As with memcached, data is cached in memory to ensure efficiency. The difference is that Redis periodically writes the updated data to disk or writes the modified operation to the appended record file, and

The file that corresponds to the Redis network Connection library is networking.c. This file is primarily responsible for client creation and release commands receive and command reply

I analyzed the redis source code for nearly a month, and reached the core, closest to the beginning of the system. I named it the main directory, there are two important files, redis-CLI and redis files, one representing the client's execution file and the other representing the server's files, these two are also the most core modules of the entire system, so I w

When the business needs a large number of connections to Redis or hbase, a large number of connections will cause a large number of sockets, the result is that the server does not have more ports to allocate, in this case the best solution is to implement the client connection of a singleton mode, keep the connection is always the same.
