Finally have time to tidy up their notes ....First, Introduction REmoteDIctionary Server (Redis) is a key-value Storage System . Similar to memcached, it supports storing more value types, including string (string), list ( linked list ), set (set),

This experiment is based on the successful installation of Redis server. The following steps are required to install the Redis extension:1, open the php.ini file, and find the code: Extension=php_redis.dll, and remove the previous # good, if not

Configuration of Redis Configuration Method Through the redis.conf file The redis.conf configuration can be overridden by command-line arguments The config set command dynamically modifies a subset of Redis configurations without

Redis has two storage methods, the default is the snapshot way, the implementation method is to periodically persist the memory snapshot (snapshot) to the hard disk, the disadvantage is that if the crash occurs after persistence, it will lose a

An interesting question today is that when the system loads a string type of shaping data from MySQL into Redis and then takes it out of Redis, its type becomes an integer type, and the procedure is as follows:The key in the database is a

Set the data expiration time by expire the key seconds command. A return of 1 indicates that the setting was successful, and returning 0 indicates that the key does not exist or the expiration is not successfully set.After the expiration time is set

Although Redis has excellent performance, we can still master/slave this simple architecture, read and write separation, further mining redis performance, improve system availability. How does Redis perform master-slave replication? Redis

SynchronousWhy should Redis implement master-slave synchronization?Master-Slave synchronization, with the following benefits: Realize the backup of data, reduce the loss of single point of failure; Helps to achieve load balancing.

I. What persistence mechanisms are provided by Redis:1). RDB Persistence:The mechanism is to write a snapshot of the in-memory data set to disk within a specified interval of time.2). AoF Persistence:This mechanism will record every write processed

Redis is an open source Key-value data cache, similar to memcached.Redis has multiple types of value, including string (string), list (linked list), set (set), Zset (sorted set-ordered set), and hash (hash type).Jedis is the official Redis-Preferred
