This article mainly explains "how to experience Redis in the Windows environment". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to experience Redis in the Windows environment".

Redis is a high-performance key-value database, using memory as the main storage, data access speed is very fast, of course, it also provides two mechanisms to support persistent data storage. Unfortunately, the Redis project does not directly support the Windows,Windows version of the project, which is an experimental project established and maintained by Microsoft's open technical team (which supports 32jue 64-bit), so it is not suitable for production environment, but can be used for development and testing in Windows environment.

1. Download and install

Poke here to the open source home page, download the source package, decompress the ZIP package and enter the msvs\ bin\ release folder. There are three files corresponding to 32 release 64 bits and three versions of windows service. Here we choose 64 bits as an example to extract redisbin64.zip to D:\ redis2.4, where redis-server.exe and redis-cli.exe are mainly used, redis-server is used to run Redis server, redis-cli is a command line client, and Redis server is connected through it. And use the Redis command to perform various operations.

two。 Service startup configuration

Copy redis.conf to D:\ redis2.4 under the root directory of the source package, open the CMD command prompt, and enter the following command to start the redis service.

Start:

Redis-server redis.conf

Thus, the redis service starts successfully.

Configuration:

Changing the configuration of redis requires modifying the redis.conf file, and here are some of its main configuration comments:

# whether to run daemonize no#Redis as a daemon, the default listening port port 637 is idle for how many seconds, disconnect timeout 30 log display level loglevel verbose# specifies the file name of log output, or you can specify the number of databases to be set to the standard output port logfile redis.log#. The default is 16, and the default connected database is 0.

Master-slave replication

Configure slaveof in the slave server configuration file and fill in the server IP and port. If the master server has set the connection password, specify the password after masterauth.

Persistence

Redis provides two types of persistent copy, Dump persistence and AOF log file persistence.

Dump persistence is to write all the data in memory to the data file, which is triggered by the configuration policy. If the trigger condition is not reached after the data change, part of the data will be lost due to failure.

AOF persistence is stored in logs and is in the form of increments, recording every action of data operations, and data recovery is generated based on these logs.

3. Command line operation

Use the CMD command prompt to open redis-cli to connect to the redis server, or you can use the telnet client

# redis-cli-h server-p port-a password

Redis-cli.exe-h 127.0.0.1-p 6379

After the connection is successful, you can add, delete, modify and query redis data, such as string operation:

Here are some common server management commands:
