简介：Redis是一个NOSQL数据库，它是一款key-values存储型数据库，也叫“memcached改进版”，它不同与memcached最大特点是它由内存+硬盘来存储数据的，它支持存储的values类型很多，包括string字符串、list链表、set集合、zset有序集合、散列表等。这些数据类型都支持push/pop、add/remove及取交集并集和差集及更丰富的操作，而且这些操作都是原子性的。Redis支持不同方式的排序，与memcached一样，数据都是缓存在内存中的，但会定期把更新的数据写入硬盘，在此基础上实现了master-slave主从同步。Redis还提供了广泛的开发语言客户端，ruby、perl、java、c、c++、PHP、scala、clojure、node.js、objective-C
一、实验环境
1.系统类型
[leo@h4 etc]$ cat issue
CentOS Linux release 6.0 (Final)
Kernel \r on an \m
2.系统位数
[leo@h4 桌面]$ getconf LONG_
32
Linux ISO：CentOS-6.0-i386-bin-DVD.iso 32位
JDK version："1.6.0_25-ea"
虚拟机：Product VMware® Workstation Version 7.0.0 build-203739
3.CentOS需要能连入网络，这个比较简单，可以参考《NOSQL系列-memcached安装管理与repcached高可用性》，这篇文章在一开始就介绍了虚拟机如何连接上网
4.Redis版本：redis.i386 0:2.4.10-1.el5
5.EPLE版本：
6.Ruby 版本：ruby-1.9.2-p180
二、Redis 安装与配置
1.我们使用yum方式安装redis数据库
[root@h4 ~]# ping 202.99.96.68 测试一下，现在我们可以连接到外网
PING 202.99.96.68 (202.99.96.68) 56(84) bytes of data.
64 bytes from 202.99.96.68: icmp_seq=1 ttl=245 time=4.14 ms
64 bytes from 202.99.96.68: icmp_seq=2 ttl=245 time=4.44 ms
64 bytes from 202.99.96.68: icmp_seq=3 ttl=245 time=4.12 ms
64 bytes from 202.99.96.68: icmp_seq=4 ttl=245 time=5.60 ms
注：如果是新启动的VMware系统，有可能会连不上网，没关系，我们重启下network服务即可恢复
[root@h4 ~]# service network restart
[root@h4 ~]# yum install redis

Setting up Install Process
No package redis available. 没有可用的redis包
Error: Nothing to do
CentOS是RedHat企业版（收费）编译过来的社区版（免费），去掉了所有关于版权问题的东西。如果我们想使用收费版yum源（软件包齐全），我们就需要安装EPEL(Extra Packages for Enterprise Linux )即企业版Linux的扩展包，EPLE提供了很多Redhat和Centos共用的组件，安装完这个以后基本常用的rpm包都可以找到了^_^
32位系统选择：（我是32位）
[root@h4 ~]# rpm -ivh ... ease-5-4.noarch.rpm
Retrieving ... ease-5-4.noarch.rpm

1:epel-release ########################################### [100%]
64位系统选择：
rpm -ivh
近水楼台先得月可参考 感谢zhaoyg 童鞋，它是64位
下面我们再次安装redis -> yum install redis
[root@h4 ~]# yum install redis

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 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 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 implement redis counter
Apr 10, 2025 pm 10:21 PM
Redis counter is a mechanism that uses Redis key-value pair storage to implement counting operations, including the following steps: creating counter keys, increasing counts, decreasing counts, resetting counts, and obtaining counts. The advantages of Redis counters include fast speed, high concurrency, durability and simplicity and ease of use. It can be used in scenarios such as user access counting, real-time metric tracking, game scores and rankings, and order processing counting.
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.
How to optimize the performance of debian readdir
Apr 13, 2025 am 08:48 AM
In Debian systems, readdir system calls are used to read directory contents. If its performance is not good, try the following optimization strategy: Simplify the number of directory files: Split large directories into multiple small directories as much as possible, reducing the number of items processed per readdir call. Enable directory content caching: build a cache mechanism, update the cache regularly or when directory content changes, and reduce frequent calls to readdir. Memory caches (such as Memcached or Redis) or local caches (such as files or databases) can be considered. Adopt efficient data structure: If you implement directory traversal by yourself, select more efficient data structures (such as hash tables instead of linear search) to store and access directory information
