With the continuous acceleration of urbanization and the rapid development of information technology, smart city construction has gradually become an important strategic direction for the development of global cities. Smart cities use information technology and Internet of Things technology to realize digital and intelligent management of various urban facilities, improving urban operational efficiency and quality of life. However, the construction of smart cities requires strong data support and efficient data management, and the Redis database is an important support in smart cities. This article will introduce the actual application of Redis in smart cities and discuss the important role of the Redis database in the construction of smart cities.
1. Overview of Redis
Redis is an efficient open source memory cache database that supports a variety of data structures (such as strings, hash tables, lists, etc.) and provides rich data Operation commands allow you to quickly store and find data. As a database that pursues high performance and high availability, Redis has been widely used in the industry. The main features of Redis include:
- Efficient data caching: Redis stores data in memory to provide efficient data access and read and write performance, and can meet high traffic and high concurrency application scenarios.
- Supports multiple data structures: Redis supports multiple data structures and can be flexibly used when storing and querying data.
- Provide rich data operation commands: Redis provides rich data operation commands, which can realize a variety of data processing and storage operations.
- Support persistent storage: Redis supports persisting data in memory to disk to achieve persistent storage of data and cold backup of data.
2. Application scenarios of Redis in smart cities
The construction of smart cities requires strong data support and efficient data management, and the Redis database is an important part of smart cities. support. The following introduces several typical application scenarios of Redis in smart cities:
- Smart Traffic Management
Smart traffic management is an important direction in the construction of smart cities. Traffic management departments need to understand urban road conditions in real time, quickly respond to traffic conditions, and implement regulation. Redis can be used as a structured data storage and high-response rate database for smart traffic management to store data such as traffic flow and road smoothness, and can efficiently handle complex query requests.
- Smart Public Management
Smart public management includes digital management of public service facilities, such as facility management for public transportation, garbage disposal, urban management and other departments. Redis can serve as a data repository for these public facilities, quickly storing and querying data, and providing data parsing and statistical analysis capabilities to support better data monitoring and management.
- Smart City Security
Smart city security is an important smart city application field. Redis can be used as a time series signal database for smart city security, supporting high-speed storage and query of massive video signals, image signals, audio signals, etc., providing corresponding support for urban security.
3. Practical application of Redis in smart city construction
Smart city construction requires efficient, reliable, and durable data support and data management, and the Redis database is an important support in smart cities . Below we will introduce practical application cases of Redis in smart city construction projects.
- Real-time traffic monitoring
In smart city traffic management systems, real-time monitoring of traffic condition information is very important. The system needs to store a large amount of traffic data, such as traffic flow, road conditions, vehicle speed information, etc., and perform real-time data processing and query analysis through data aggregation and analysis technology. In order to provide faster query response and higher data processing efficiency, the system uses the Redis database as the core technology for data storage and data operation.
- Garbage Classification Management
The smart city garbage classification management system requires rapid query, classification management and statistical analysis of garbage classification information. As a fast and efficient data cache and query engine, the Redis database is used in the storage and query of garbage classification information to improve the system's query response efficiency and database operation speed.
- Smart grid monitoring
The smart city grid monitoring system needs to monitor and manage the city’s power supply and consumption in real time. This system requires real-time collection, storage, analysis and statistics of power signals. As an efficient in-memory database, Redis supports fast storage and fast query, and is used in smart grid monitoring systems to improve system response speed and data processing efficiency.
4. Summary
As an efficient memory cache database, Redis has high-speed storage, fast query and data statistical analysis capabilities, and can provide strong support for data management in smart city construction. Redis has been widely used in the fields of smart city traffic management, public service management, and urban security, and has broad application prospects and important significance. In the future, as the construction of smart cities continues to deepen, the application of Redis will be more widely expanded and further developed.

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.

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)

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.

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.

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.

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
