Can Linux systems directly execute .sh scripts?

Linux is suitable for servers, development environments, and embedded systems. 1. As a server operating system, Linux is stable and efficient, and is often used to deploy high-concurrency applications. 2. As a development environment, Linux provides efficient command line tools and package management systems to improve development efficiency. 3. In embedded systems, Linux is lightweight and customizable, suitable for environments with limited resources.

Using Docker on Linux can improve development and deployment efficiency. 1. Install Docker: Use scripts to install Docker on Ubuntu. 2. Verify the installation: Run sudodockerrunhello-world. 3. Basic usage: Create an Nginx container dockerrun-namemy-nginx-p8080:80-dnginx. 4. Advanced usage: Create a custom image, build and run using Dockerfile. 5. Optimization and Best Practices: Follow best practices for writing Dockerfiles using multi-stage builds and DockerCompose.

When the Apache 80 port is occupied, the solution is as follows: find out the process that occupies the port and close it. Check the firewall settings to make sure Apache is not blocked. If the above method does not work, please reconfigure Apache to use a different port. Restart the Apache service.

The steps to start Apache are as follows: Install Apache (command: sudo apt-get install apache2 or download it from the official website) Start Apache (Linux: sudo systemctl start apache2; Windows: Right-click the "Apache2.4" service and select "Start") Check whether it has been started (Linux: sudo systemctl status apache2; Windows: Check the status of the "Apache2.4" service in the service manager) Enable boot automatically (optional, Linux: sudo systemctl

The steps to start an Oracle listener are as follows: Check the listener status (using the lsnrctl status command) For Windows, start the "TNS Listener" service in Oracle Services Manager For Linux and Unix, use the lsnrctl start command to start the listener run the lsnrctl status command to verify that the listener is started

This article describes how to effectively monitor the SSL performance of Nginx servers on Debian systems. We will use NginxExporter to export Nginx status data to Prometheus and then visually display it through Grafana. Step 1: Configuring 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

This article introduces two methods of configuring a recycling bin in a Debian system: a graphical interface and a command line. Method 1: Use the Nautilus graphical interface to open the file manager: Find and start the Nautilus file manager (usually called "File") in the desktop or application menu. Find the Recycle Bin: Look for the Recycle Bin folder in the left navigation bar. If it is not found, try clicking "Other Location" or "Computer" to search. Configure Recycle Bin properties: Right-click "Recycle Bin" and select "Properties". In the Properties window, you can adjust the following settings: Maximum Size: Limit the disk space available in the Recycle Bin. Retention time: Set the preservation before the file is automatically deleted in the recycling bin

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
