This will enable access logging on your server. You can also configure nginx to log additional information, such as the referrer URL and user agent, by adding the following line:
log_format main ‘$remote_addr – $remote_user [$time_local] “$request” ”$status $body_bytes_sent “$http_referer” ””$http_user_agent” “$http_x_forwarded_for”‘;
Once you’ve made your changes, save the file and restart nginx using the following command:
sudo service nginx restart

FAQs
What is the Difference Between Chef Server and Chef Workstation?
Chef server is a central hub that stores all the configurations and metadata necessary for managing a server infrastructure. Chef workstation, on the other hand, is a tool used for developing, testing, and deploying cookbooks and other Chef resources. While the two tools are related, they serve different functions in the Chef ecosystem.
What is the Chef Client?
The chef client is a tool used to manage the configuration of nodes (servers) in a chef server infrastructure. It runs on each node and communicates with the chef server to download and apply configurations.
How Do I Install Chef Server?
You can install chef server by following the instructions provided by Chef Software, the company behind the tool. The installation process varies depending on your operating system and environment, so be sure to read the relevant documentation carefully.
What Are the Different Types of Nginx Logs?
Nginx generates several different types of logs, including access logs, error logs, and process logs. Access logs record details about every request received by the server, while error logs record details about server errors. Process logs provide information about the Nginx processes running on the server.
How Do I Analyze Nginx Logs?
There are several tools available for analyzing Nginx logs, including grep and awk. These tools enable you to extract valuable information from the logs and highlight potential issues with server performance.
