All redis data is stored in the memory, but it also provides persistence for the data.6.1 data Snapshot
The principle of data snapshot is to traverse all data stored in redis to a data file with the extension RDB. You can

First, design ideas:
When Master and Slave are operating normally, Master is responsible for service, Slave is responsible for standby;
When Master hangs out, Slave Normal, Slave takes over the service, has the Write permission, simultaneously closes the master-slave copy function;
When Master returns to normal, the data is synchronized from the slave, the master-slave copy function is turned off after the data is synchronized, and the master is restored, while sla

Redis Summary-Redis installation, redis summary Installation
Redis needs to be used in recent projects. We will record the installation of Redis and how to use Redis in. NET within the past two days.
Suppose two redis servers, IP: 192.168.1.101 and 192.168.1.103, how do I access Redis on 101 through REDIS-CLI on the 103? before remote connection 103, let's talk about some key parameters of Redis-cli:Usage: redis-cli [OPTIONS] [cmd [arg [arg ...]]-H -p -A --help, display
, Mac OS X, Solaris, etc. In addition, redis does not rely on any non-standard library, nor does it need to add compilation parameters. Make is the only thing we need to compile and install redis.
1. download the latest redis version 2.2.12.

Wget http://redis.googlecode.com/files/
Assume that the two redis servers have ip addresses 192.168.1.101 and 192.168.1.103 respectively. How can I access redis on redis 101 through redis-cli on redis 103? Before remotely connecting to redis 103, let's talk about severa
Performance-related data indicators
Access the redis server through the redis-cli interface, and then use the info command to obtain all information related to the redis service. This information is used to analyze some performance indicators mentioned later in the article.
The data output by the info command can be divided into 10 categories:
Server
Clients

Redis-load and Redis-stat are two small tools written by the Redis author Antirez, including:
Redis-load is a stress test tool for Redis
Redis-stat is a Redis status
Redis Summary (4) Redis persistence, redis Summary
I have summarized the installation and use of Redis. Today I will talk about Redis persistence.
Similar to memcached, redis is a memory database. However,
Data partitioningRedis clusters store data on multiple nodes, that is, different partitions are stored on different nodes, and each node can store multiple partitions. Each partition is also referred to as a "hash slot" in Redis, with a total of 16,384 partitions planned in the Redis cluster. For example: when there are 3 nodes in a cluster, Node A will contain 0-5460 partitions, Node B will contain 5461-10

If both RDB and AOF are configured, the boot is only loaded with AOF file recovery data;
If only the RDB is configured, startup is the load dump file to recover the data.
