How to build a redis cluster under windows
Foreword:
Clustering refers to providing the same service by adding the number of servers, so as to achieve a stable and efficient state. Why use redis cluster? The redis cluster can enhance the reading and writing capabilities of redis.
Now let’s formally learn about redis cluster.
Preparation work:
Requires 4 components: Redis, Ruby language runtime environment, Redis Ruby driver redis-xxxx.gem, and the tool to create a Redis cluster redis-trib.rb. Use the redis-trib.rb tool to create a Redis cluster. Since this file is written in ruby language, you need to install the Ruby development environment and drive redis-xxxx.gem.
1) Download the Redis installation file: https://github.com/MSOpenTech/redis/releases/, Redis provides download files in msi and zip formats, download zip here Format Redis-x64-3.2.100 version.
2) Download the Ruby installation file: http://dl.bintray.com/oneclick/rubyinstaller/rubyinstaller-2.2.4-x64.exe
3) Download Redis in the Ruby environment Driver: https://rubygems.org/gems/redis/versions/3.2.2. Considering compatibility, the 3.2.2 version is downloaded here.
Note: Download the related link in the lower right corner of the page.中
4) Download the ruby script file redis-trib.rb officially provided by Redis to create a Redis cluster. The path is as follows: https://raw.githubusercontent.com/MSOpenTech /redis/3.0/src/redis-trib.rb
Install Redis
Just decompress the downloaded Redis-x64-3.2.100.zip. For ease of use, it is recommended to put it in In the root directory of the drive letter, such as: D:\Redis-Cluster\Redis-x64-3.2.100.
Install Redis and run 3 instances (Redis cluster requires at least 3 nodes, less than 3 cannot be created);
Start 6 different Redis instances through configuration files, Since the default port of Redis is 6379, 6380, 6381, 6382, 6383, 6384, and 6385 are used here to run 6 Redis instances.
Note:
(1) In order to avoid unnecessary errors, try to save the configuration file in utf8 format and do not include comments;
(2) The following in the configuration file There are two ways to save logs (save in files and save in System Log). Please choose one according to your needs:
loglevel notice #日志的记录级别，notice是适合生产环境的 logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6380_log.txt" #指定log的保持路径,默认是创建在Redis安装目录下，如果有子目录需要手动创建，如此处的Logs目录 syslog-enabled yes #是否使用系统日志 syslog-ident redis6380 #在系统日志的标识名
The method of saving in files is used here, so first save in the Redis directory Create a new Logs folder under D:\Redis-Cluster\Redis-x64-3.2.100.
In the root directory of the Redis installation, create configuration files with encoding format utf-8: redis.6380.conf, redis.6381.conf, redis.6382.conf, redis.6383.conf, redis. 6384.conf, redis.6385.conf.
redis.6380.conf、
port 6380 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6380_log.txt" appendonly yes appendfilename "appendonly.6380.aof" cluster-enabled yes cluster-config-file nodes.6380.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6381.conf、
port 6381 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6381_log.txt" appendonly yes appendfilename "appendonly.6381.aof" cluster-enabled yes cluster-config-file nodes.6381.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6382.conf、
port 6382 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6382_log.txt" appendonly yes appendfilename "appendonly.6382.aof" cluster-enabled yes cluster-config-file nodes.6382.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6383.conf、
port 6383 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6383_log.txt" appendonly yes appendfilename "appendonly.6383.aof" cluster-enabled yes cluster-config-file nodes.6383.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6384.conf、
port 6384 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6384_log.txt" appendonly yes appendfilename "appendonly.6384.aof" cluster-enabled yes cluster-config-file nodes.6384.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6385.conf
port 6385 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6385_log.txt" appendonly yes appendfilename "appendonly.6385.aof" cluster-enabled yes cluster-config-file nodes.6385.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
(Learning video sharing: redis video tutorial)
The configuration is explained as follows:
port 6380 #端口号 loglevel notice #日志的记录级别，notice是适合生产环境的 logfile "Logs/redis6380_log.txt" #指定log的保持路径,默认是创建在Redis安装目录下，如果有子目录需要手动创建，如此处的Logs目录 syslog-enabled yes #是否使用系统日志 syslog-ident redis6380 #在系统日志的标识名 appendonly yes #数据的保存为aof格式 appendfilename "appendonly.6380.aof" #数据保存文件 cluster-enabled yes #是否开启集群 cluster-config-file nodes.6380.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
Save the above configuration files to the Redis directory, and use these configuration files to install 6 A redis service, the command is as follows:
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6380.conf --service-name redis6380 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6381.conf --service-name redis6381 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6382.conf --service-name redis6382 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6383.conf --service-name redis6383 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6384.conf --service-name redis6384 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6385.conf --service-name redis6385
Note:
1) It is best to use the full path for configuration files such as redis.6380.conf to avoid problems when restarting the Redis cluster
2) The uninstall command is:
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6380.conf --service-name redis6380 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6381.conf --service-name redis6381 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6382.conf --service-name redis6382 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6383.conf --service-name redis6383 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6384.conf --service-name redis6384 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6385.conf --service-name redis6385
Start these 6 services. The command is as follows:
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6380 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6381 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6382 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6383 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6384 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6385
Execution result:

How to build the redis cluster mode
Apr 10, 2025 pm 10:15 PM
Redis cluster mode deploys Redis instances to multiple servers through sharding, improving scalability and availability. The construction steps are as follows: Create odd Redis instances with different ports; Create 3 sentinel instances, monitor Redis instances and failover; configure sentinel configuration files, add monitoring Redis instance information and failover settings; configure Redis instance configuration files, enable cluster mode and specify the cluster information file path; create nodes.conf file, containing information of each Redis instance; start the cluster, execute the create command to create a cluster and specify the number of replicas; log in to the cluster to execute the CLUSTER INFO command to verify the cluster status; make
How to clear redis data
Apr 10, 2025 pm 10:06 PM
How to clear Redis data: Use the FLUSHALL command to clear all key values. Use the FLUSHDB command to clear the key value of the currently selected database. Use SELECT to switch databases, and then use FLUSHDB to clear multiple databases. Use the DEL command to delete a specific key. Use the redis-cli tool to clear the data.
How to use the redis command
Apr 10, 2025 pm 08:45 PM
Using the Redis directive requires the following steps: Open the Redis client. Enter the command (verb key value). Provides the required parameters (varies from instruction to instruction). Press Enter to execute the command. Redis returns a response indicating the result of the operation (usually OK or -ERR).
How to use redis lock
Apr 10, 2025 pm 08:39 PM
Using Redis to lock operations requires obtaining the lock through the SETNX command, and then using the EXPIRE command to set the expiration time. The specific steps are: (1) Use the SETNX command to try to set a key-value pair; (2) Use the EXPIRE command to set the expiration time for the lock; (3) Use the DEL command to delete the lock when the lock is no longer needed.
How to read redis queue
Apr 10, 2025 pm 10:12 PM
To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.
How to use single threaded redis
Apr 10, 2025 pm 07:12 PM
Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.
How to implement the underlying redis
Apr 10, 2025 pm 07:21 PM
Redis uses hash tables to store data and supports data structures such as strings, lists, hash tables, collections and ordered collections. Redis persists data through snapshots (RDB) and append write-only (AOF) mechanisms. Redis uses master-slave replication to improve data availability. Redis uses a single-threaded event loop to handle connections and commands to ensure data atomicity and consistency. Redis sets the expiration time for the key and uses the lazy delete mechanism to delete the expiration key.
How to read the source code of redis
Apr 10, 2025 pm 08:27 PM
The best way to understand Redis source code is to go step by step: get familiar with the basics of Redis. Select a specific module or function as the starting point. Start with the entry point of the module or function and view the code line by line. View the code through the function call chain. Be familiar with the underlying data structures used by Redis. Identify the algorithm used by Redis.
