redis 7.4 安装

### Redis 7.4 Installation Guide For the installation of Redis version 7.4 within a Node.js environment, one can utilize NPM (Node Package Manager), which comes bundled with Node.js installations. The command to install the `redis` package via NPM is as follows: ```bash ./npm install redis ``` This command installs the latest compatible version of the Redis client library for use in Node.js applications at the time of writing this guide; however, specific versions like Redis 7.4 might require additional steps or direct downloads from official sources since NPM packages may not always correspond directly to server-side Redis versions[^1]. To ensure compatibility and functionality when working with a specified version such as Redis 7.4, consider downloading it directly from the official website or repository suitable for your operating system. After obtaining the desired version, follow the platform-specific instructions provided by the Redis documentation. #### Verifying Installation on Linux Systems After installing Redis through appropriate channels, verify its successful setup using commands tailored towards checking service status and running instances. For systems based on CentOS or similar distributions where YUM is available, managing OpenStack components could provide insights into handling services but does not apply specifically here unless integrating with cloud infrastructure[^3]. Instead, focus on basic verification methods applicable across Unix-like environments: ```bash systemctl start redis.service systemctl enable redis.service systemctl status redis.service ``` These commands initiate the Redis service, set it to launch upon boot, and display current operational details about the process respectively. #### Configuring Access Credentials When configuring access credentials for databases connected over HTTP interfaces—such as those mentioned while setting up web-based platforms—it's important to adhere closely to security best practices rather than default settings that expose sensitive information publicly[^2]. Ensure strong passwords are used instead of examples given (`root/root`) during actual deployments. #### Customizing Backend Paths In scenarios involving e-commerce solutions built atop frameworks requiring backend configuration files—for instance, Magento—the ability to customize admin URLs enhances both usability and security measures against unauthorized access attempts[^4]. While this customization pertains more so to application-level configurations post-installation, understanding how paths influence overall architecture remains beneficial knowledge.
