redis在windows下安装和PHP中使用,redisphp

1、redis简介
redis是一个key-value存储系统。和Memcached类似,它支持存 储的value类型相对更多,包括string(字符串)、list(链表)、set(集合)、zset(sorted set --有序集合)和hashs(哈希类型)。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。在此基础上,redis支持各种不同方式的排序。与memcached一样,为了保证效率,数据都是缓存在内存中。区别的是redis会周期性的把更新的数据写入磁盘或者把修改操作写入追加的记录文件,并且在此基础上实现了master-slave(主从)同步。

Redis 是一个高性能的key-value数据库。 redis的出现,很大程度补偿了memcached这类key/value存储的不足,在部分场合可以对关系数据库起到很好的补充作用。它提供了Python,Ruby,Erlang,PHP客户端,使用很方便。

2、windows下安装redis
下载地址https://github.com/dmajkic/redis/downloads。下载到的Redis支持32bit和64bit。根据自己实际情况选择,我选择32bit。把32bit文件内容拷贝到需要安装的目录下,比如:D:\dev\redis-2.4.5。

打开一个cmd窗口,使用cd命令切换到指定目录(D:\dev\redis-2.4.5)运行 redis-server.exe redis.conf 。运行以后出现如下界面。

这就说明Redis服务端已经安装成功。

重新打开一个cmd窗口,使用cd命令切换到指定目录(D:\dev\redis-2.4.5)运行 redis-cli.exe -h 127.0.0.1 -p 6379,其中 127.0.0.1是本地ip,6379是redis服务端的默认端口。运行成功如下图所示。
这样,Redis windows环境下搭建已经完成,是不是很简单。

这样,Redis windows环境下搭建已经完成,是不是很简单。

环境已经搭建好,总得测试下吧。比如:存储一个key为test,value为hello word的字符串,然后获取key值。

正确输出 hell word,测试成功!

 

3、PHP中使用

下载 dll文件

http://download.csdn.net/download/bluesky321/5355093

php_redis.dll 扩展 For PHP5.4.x

 

PHP5.4.x 的 redis 扩展 php_redis.dll

测试平台:Windows XPx32 (FastCGI PHP5.4.9 Nginx 1.4.0)

 

包含 Non Thread Safe 和 Thread Safe 两个版本

 

首先把php_redis.dll 和 php_igbinary.dll 放入PHP的ext文件夹,然后在php.ini配置文件里添加如下代码:

 

extension=php_igbinary.dll

extension=php_redis.dll

 

重启web服务器

 

注意:extension=php_igbinary.dll一定要放在extension=php_redis.dll的前面,否则此扩展不会生效

4、PHP中使用

代码如下

<?<span>php
    <span>$redis = <span>new<span> Redis();
    <span>$redis->connect('127.0.0.1',6379<span>);
    <span>$redis->set('test','hello redis'<span>);
    <span>echo <span>$redis->get('test'<span>);
?></span></span></span></span></span></span></span></span></span></span></span>
Copy after login

输出 hello  redis 成功!

How to build the redis cluster mode 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 read redis queue 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 clear redis data 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 configure Lua script execution time in centos redis 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 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 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 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

How to implement redis counter 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.
