Using Redis applications in ThinkPHP6
With the rapid development of the Internet and the advent of the big data era, the demand for high-concurrency solutions has become increasingly urgent. As a high-performance non-relational database, Redis is also popular for its excellent performance. In ThinkPHP6, we can also easily integrate Redis, making our applications more scalable and capable of high concurrency processing.
Redis is a key-value NoSQL database that runs based on memory. It is written in C language, so it has excellent performance and efficient data storage capabilities. Compared with traditional relational databases, the advantage of Redis is that it can quickly handle a large number of read and write requests, and supports operations on a variety of data structures, such as string, hash, list, set, sorted set, etc. Therefore, we can use Redis as a data cache to improve application performance.
Using Redis in ThinkPHP6 is very simple. We only need to add the following code to the configuration file:
return [ 'default' => [ // 数据库类型 'type' => 'mysql', // 服务器地址 'hostname' => '127.0.0.1', // 数据库名 'database' => 'test', // 用户名 'username' => 'root', // 密码 'password' => '', // 端口 'hostport' => '', // 连接dsn 'dsn' => '', // 数据库连接参数 'params' => [], // 数据库编码默认采用utf8 'charset' => 'utf8', // 数据库表前缀 'prefix' => '', // 数据库调试模式 'debug' => true, // 添加Redis配置 'redis' => [ 'type' => 'redis', 'hostname' => '127.0.0.1', 'port' => 6379, 'password' => '', 'select' => 0, 'timeout' => 0, ], ], // ... ];
In the above configuration file, we added the Redis configuration item, among which It includes parameters such as Redis host address, port number, password, and selected database number. In the database configuration, we need to specify type as redis so that ThinkPHP6 can recognize that this is a Redis database connection.
After adding the Redis configuration in the configuration file, we can use Redis to operate data in the application. For example, we can use the following code to store data into Redis:
use thinkacadeCache; // 缓存数据 Cache::store('redis')->set('name', 'Tom'); // 获取数据 $name = Cache::store('redis')->get('name');
In the above code, we use the think acadeCache class to operate cached data. We store the cache in Redis through the store method and obtain the cache data through the get method. When fetching data, if the cache does not exist, false will be returned.
In addition, we can also use the rich data structure operation functions provided by Redis to operate data. For example, we can use the following code to operate on list type data:
use thinkacadeCache; use thinkcachedriverRedis; // 存储list数据 $redis = (new Redis())->handler(); $redis->lPush('list', 'Tom'); $redis->rPush('list', 'Jerry'); // 获取list数据 $list = $redis->lRange('list', 0, -1);
In the above example code, we use the lPush and rPush methods provided by Redis to store list data. Among them, the lPush method means inserting data from the left side of the list, and the rPush method means inserting data from the right side of the list. When we get data, we can also use the lRange method to get all the data in the list.
In summary, using Redis in ThinkPHP6 is very simple. We only need to add Redis configuration items in the configuration file. Then you can easily operate cached data through the think acadeCache class and the data structure operation functions provided by Redis. Using Redis's high performance and multiple data structure operation capabilities, we can easily improve the performance and high concurrency processing capabilities of the application.

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: 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.

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.

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).

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.

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.

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.

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)
