redis实现点击量浏览量,该如何处理
redis实现点击量浏览量
业务描述
CMS文章浏览量(标题被加载量)，点击量统计(文章被点击开的量)
以下是本人设计的统计业务，主要技术redis,nodejs，redis应用点击量缓存以减少数据库压力，nodejs通过异步非阻塞机制实现CMS业务逻辑和统计功能区分
传入参数cateid(分类id),articleid(文章id)，sourceip(请求源ip)
一、存储策略
1、按时间粒度记录
redis以hash进行存储
HASH
KEY VALUE
time his
0 0
1 10
cateid_arvicleid_t . .
. .
. .
23 230
2、按来源统计
redis同样以hash进行存储，来源区分到省份
HASH
KEY VALUE
provinc his
HEBEI 0
HENAN 10
cateid_arvicleid_p . .
. .
. .
SHANDONG 230
二、数据同步机制
现在只想到通过linux计划任务定时将redis数据同步到数据库
三、缓存数据过期机制
方案一 通过redis自动过期时间
此方案需要在数据同步机制晚一些执行，保证数据入库后，清理过期缓存，现在考虑同步在每日0时执行，那么redis缓存就需要设置24小时多一点
方案二 通过数据库同步机制同时清除
此方案即把同步和清理缓存做在一起，弃用redis过期机制
小弟希望各位大神给指出不妥和优化的地方
在10000在线用户，1000并发的基础上上述redis的存储机制对内存压力是否可行
同步机制和缓存过期机制是否有更好的解决的方案
在此拜谢
------解决思路----------------------
KEY 最好设置成 2014_10_30. cateid_arvicleid_t形式
选择方案二 通过数据库同步机制同时清除 在每天凌晨的2~4点进行同步 因为脚本1.同步脚本可能失败 2.数据量大的时候昨天的0时数据会被今天的0时覆盖
号称1秒10W请求的redis 不惧1000的并发

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 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 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 configure Lua script execution time in centos redis
Apr 14, 2025 pm 02:12 PM
On CentOS systems, you can limit the execution time of Lua scripts by modifying Redis configuration files or using Redis commands to prevent malicious scripts from consuming too much resources. Method 1: Modify the Redis configuration file and locate the Redis configuration file: The Redis configuration file is usually located in /etc/redis/redis.conf. Edit configuration file: Open the configuration file using a text editor (such as vi or nano): sudovi/etc/redis/redis.conf Set the Lua script execution time limit: Add or modify the following lines in the configuration file to set the maximum execution time of the Lua script (unit: milliseconds)
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 use the redis command line
Apr 10, 2025 pm 10:18 PM
Use the Redis command line tool (redis-cli) to manage and operate Redis through the following steps: Connect to the server, specify the address and port. Send commands to the server using the command name and parameters. Use the HELP command to view help information for a specific command. Use the QUIT command to exit the command line tool.
How to set the redis expiration policy
Apr 10, 2025 pm 10:03 PM
There are two types of Redis data expiration strategies: periodic deletion: periodic scan to delete the expired key, which can be set through expired-time-cap-remove-count and expired-time-cap-remove-delay parameters. Lazy Deletion: Check for deletion expired keys only when keys are read or written. They can be set through lazyfree-lazy-eviction, lazyfree-lazy-expire, lazyfree-lazy-user-del parameters.
