How to use Nginx Proxy Manager to collect and analyze website access logs

Introduction:
With the rapid development of the Internet, website log analysis has become important of a link. By collecting and analyzing website access logs, we can understand users' behavioral habits, optimize website performance, and improve user experience. This article will introduce how to use Nginx Proxy Manager to collect and analyze website access logs, including specific steps such as configuring Nginx Proxy Manager, collecting website access logs, and storing and analyzing log data. At the same time, relevant code examples are provided for reference.

1. Configure Nginx Proxy Manager

1. Install Nginx Proxy Manager
   First, we need to install Nginx Proxy Manager. You can download the latest version of Nginx Proxy Manager through the official website (https://nginxproxymanager.com/) and install it according to the documentation.
2. Configuring Nginx
   After the installation is completed, Nginx needs to be configured. In the Nginx configuration file, add the following configuration section:

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        # 其他代理相关配置...
    }
}

Among them, example.com is the domain name to be proxied, http://localhost:8080 is the actual web server address.

3. Configure SSL certificate
   If you need to enable HTTPS access, you need to configure an SSL certificate. Certificate configuration and management can be completed through the web interface of Nginx Proxy Manager.

2. Collect website access logs

1. Enable Nginx access logs
   In the Nginx configuration file, add the following configuration section:

http {
    access_log /var/log/nginx/access.log;
    # 其他日志相关配置...
}

Among them, /var/log/nginx/access.log is the path of the log file.

2. Configure log format
   In order to facilitate analysis and storage, you can configure a custom log format. In the Nginx configuration file, add the following configuration section:

http {
    log_format main '$remote_addr - $remote_user [$time_local] "$request" '
                    '$status $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for"';

    access_log /var/log/nginx/access.log main;
    # 其他日志相关配置...
}

3. Restart Nginx
   After completing the above configuration, restart the Nginx service to make the configuration take effect.

3. Store and analyze log data

1. Install ELK Stack
   In order to store and analyze log data, you can use ELK Stack (Elasticsearch, Logstash, Kibana). You can download the latest version of ELK Stack through the official website (https://www.elastic.co/) and install it according to the documentation.
2. Configuring Logstash
   In the Logstash configuration file, add the following configuration section:

input {
    file {
        path => "/var/log/nginx/access.log"
        start_position => "beginning"
        sincedb_path => "/dev/null"
        ignore_older => 0
    }
}

filter {
    # 数据过滤配置...
}

output {
    elasticsearch {
        hosts => ["localhost"]
        index => "nginx-%{+YYYY.MM.dd}"
    }
}

Among them, /var/log/nginx/access.logThe path to the Nginx access log file.

3. Configuring Kibana
   In the Kibana configuration file, modify the following configuration items:

elasticsearch.hosts: ["http://localhost:9200"]

4. Log analysis and visualization

1. Access Kibana
   Access Kibana’s address in the browser (default is http://localhost:5601).
2. Create index
   In Kibana, create an index named "nginx-*" so that Nginx access logs can be queried and visualized.
3. Application Query and Visualization
   In Kibana, you can create various queries and visualization charts to analyze Nginx access logs. For example, you can create a dashboard that includes charts such as number of visits, visit sources, visit frequency, and more.
