This article describes how to effectively monitor the SSL performance of Nginx servers on Debian systems. We will use Nginx Exporter to export Nginx status data to Prometheus and then visually display it through Grafana.
Step 1: Configure Nginx
First, we need to enable the stub_status
module in the Nginx configuration file to obtain the status information of Nginx. Add the following snippet in your Nginx configuration file (usually located in /etc/nginx/nginx.conf
or its include file):
location /nginx_status { stub_status; access_log off; allow 127.0.0.1; # Restrict access, only local access deny all; }
Note: For security reasons, we have added access control, allowing only local IP addresses to access nginx_status
. In production environments, be sure to configure stricter access control according to actual conditions.
After the configuration is complete, run the following command to reload the Nginx configuration:
sudo nginx -t sudo nginx -s reload
Step 2: Install and run Nginx Exporter
Nginx Exporter is a tool for collecting Nginx metrics and converting them into Prometheus readable format.
- Download Nginx Exporter:
wget https://github.com/nginxinc/nginx-prometheus-exporter/releases/download/v0.11.0/nginx-prometheus-exporter_0.11.0_linux_amd64.tar.gz
- Unzip and enter the directory:
tar -zxvf nginx-prometheus-exporter_0.11.0_linux_amd64.tar.gz cd nginx-prometheus-exporter
- Start Nginx Exporter and specify the URL of Nginx
stub_status
:
./nginx-prometheus-exporter -nginx.scrape-uri=http://127.0.0.1/nginx_status
Here we assume that Nginx is running locally with port 80. Please modify the -nginx.scrape-uri
parameter according to your actual situation.
Step 3: Configure Prometheus
Prometheus is an open source monitoring and alarm system. We need to configure it to crawl the data of Nginx Exporter.
Add the following configuration in the Prometheus configuration file (usually located in /etc/prometheus/prometheus.yml
):
scrape_configs: - job_name: 'nginx' scrape_interval: 10s static_configs: - targets: ['localhost:9113'] # Nginx Exporter Default Port
After saving the configuration file, restart the Prometheus service:
sudo systemctl restart prometheus
Step 4: Use Grafana to visualize monitoring data
Import Prometheus' data into Grafana and create a dashboard to show Nginx's SSL performance metrics, such as the number of connections, requests, etc. For specific Grafana configuration steps, please refer to Grafana official documentation.
Through the above steps, you can effectively monitor Nginx's SSL performance on the Debian system. Remember to adjust the relevant configuration according to your actual environment, especially scrape_uri
of Nginx Exporter and targets
parameters of Prometheus.

The core method of building social sharing functions in PHP is to dynamically generate sharing links that meet the requirements of each platform. 1. First get the current page or specified URL and article information; 2. Use urlencode to encode the parameters; 3. Splice and generate sharing links according to the protocols of each platform; 4. Display links on the front end for users to click and share; 5. Dynamically generate OG tags on the page to optimize sharing content display; 6. Be sure to escape user input to prevent XSS attacks. This method does not require complex authentication, has low maintenance costs, and is suitable for most content sharing needs.

To realize text error correction and syntax optimization with AI, you need to follow the following steps: 1. Select a suitable AI model or API, such as Baidu, Tencent API or open source NLP library; 2. Call the API through PHP's curl or Guzzle and process the return results; 3. Display error correction information in the application and allow users to choose whether to adopt it; 4. Use php-l and PHP_CodeSniffer for syntax detection and code optimization; 5. Continuously collect feedback and update the model or rules to improve the effect. When choosing AIAPI, focus on evaluating accuracy, response speed, price and support for PHP. Code optimization should follow PSR specifications, use cache reasonably, avoid circular queries, review code regularly, and use X

User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.

There are three main ways to set environment variables in PHP: 1. Global configuration through php.ini; 2. Passed through a web server (such as SetEnv of Apache or fastcgi_param of Nginx); 3. Use putenv() function in PHP scripts. Among them, php.ini is suitable for global and infrequently changing configurations, web server configuration is suitable for scenarios that need to be isolated, and putenv() is suitable for temporary variables. Persistence policies include configuration files (such as php.ini or web server configuration), .env files are loaded with dotenv library, and dynamic injection of variables in CI/CD processes. Security management sensitive information should be avoided hard-coded, and it is recommended to use.en

The core role of Homebrew in the construction of Mac environment is to simplify software installation and management. 1. Homebrew automatically handles dependencies and encapsulates complex compilation and installation processes into simple commands; 2. Provides a unified software package ecosystem to ensure the standardization of software installation location and configuration; 3. Integrates service management functions, and can easily start and stop services through brewservices; 4. Convenient software upgrade and maintenance, and improves system security and functionality.

To enable PHP containers to support automatic construction, the core lies in configuring the continuous integration (CI) process. 1. Use Dockerfile to define the PHP environment, including basic image, extension installation, dependency management and permission settings; 2. Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction

This article aims to explore how to use EloquentORM to perform advanced conditional query and filtering of associated data in the Laravel framework to solve the need to implement "conditional connection" in database relationships. The article will clarify the actual role of foreign keys in MySQL, and explain in detail how to apply specific WHERE clauses to the preloaded association model through Eloquent's with method combined with closure functions, so as to flexibly filter out relevant data that meets the conditions and improve the accuracy of data retrieval.

The core of using PHP to combine AI to achieve automatic digest is to call AI service APIs, such as OpenAI or cloud platform NLP services; 2. Specific steps include obtaining API keys, preparing plain text, sending POST requests with curl, analyzing JSON responses and displaying the digest; 3. The digest can efficiently filter information, improve readability, assist in content management and adapting to fragmented reading; 4. Selecting a model requires consideration of the abstract type (extracted or generated), cost, language support, document ease of use and data security; 5. Common challenges include rate limiting, network timeout, text length limit, cost out of control and quality fluctuations. The response strategy includes retry mechanism, asynchronous queue, block processing, cache results and optimization prompt words.
