Redis read-write separation and sentinel mechanism configuration
1. Use the commands cp redis.conf /redis63791.conf, cp redis.conf /redis63792.conf, cp redis.conf /redis63793.conf in /etc/redis/ to The root directory is ready
vim redis63792.conf --->修改配置文件 daemonize yes 守护进程 port 63792 端口 bind 192.168.0.3 绑定内网地址 databases 16 开启16个数据库 save ---> 每多少个文件执行一次保存 (主人不需要以下操作) slaveof 116.196.107.20 63791 --> 作为该ip该端口的奴隶 masterauth '123456789' --> 认证主人的密码 ---------------------- appendonly yes 开启这个增强数据的安全性 (以上为正常的redis.conf里面的配置文件,所有的slave都要去连接主人的服务器,只能读,不能写,自动同步数据,读写分离可以大大的增强服务器的性能能,因为在正常的数据操作中, 读的时候往往比写的时候的情况要多的多, 一般情况下主从机按1:3进行分配)
2. Sentinel configuration, find the sentinel.conf file in /etc/redis (if you don’t have such a configuration file), copy cp sentinel.conf /mysentinel .conf
vim mysentinel.conf sentinel monitor mymaster 116.196.107.20 63791 1 -->分别的意思是 哨兵监听主人:116.196.107.20的 端口:63791 哨兵数量1个, 一般情况下哨兵的数量越多, 投票选举通过的几率越小, 在投票选举出新主人花费的时间就越多, 不利于快速切换主从机制 sentinel down-after-milliseconds mymaster 5000 主机掉线以后5s进行认证,如果无法连接则重新由哨兵从slave中选出新的主人 sentinel auth-pass mymaster 123456789 哨兵通过密码连接主人
3. After the configuration is completed, you can turn on the master-slave mechanism, separate reading and writing, and provide a sentinel mechanism. After the master is down for 5 seconds, a new master will be randomly selected from the slave. Previously After the master is connected, he can only work as a slave! !
redis操作命令: redis-server redis63791.conf & -->以该配置文件在后台运行服务器 redis-cli -h 116.196.107.20 -p 63791 远程连接服务器 auth 123456789 --->在redis中验证密码 redis-server mysentinel.conf --sentinel 启动哨兵模式开始监听, 如下:

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 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 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 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.
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 view all keys in redis
Apr 10, 2025 pm 07:15 PM
To view all keys in Redis, there are three ways: use the KEYS command to return all keys that match the specified pattern; use the SCAN command to iterate over the keys and return a set of keys; use the INFO command to get the total number of keys.
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 start the server with redis
Apr 10, 2025 pm 08:12 PM
The steps to start a Redis server include: Install Redis according to the operating system. Start the Redis service via redis-server (Linux/macOS) or redis-server.exe (Windows). Use the redis-cli ping (Linux/macOS) or redis-cli.exe ping (Windows) command to check the service status. Use a Redis client, such as redis-cli, Python, or Node.js, to access the server.
