Linux version differences
Linux version differences
One type is the RedHat series maintained by commercial companies, which is characterized by a large number of users and a lot of data; the other type is the RedHat series maintained by commercial companies. Class is the Debian series maintained by community organizations. This series is relatively stable and supports many new technologies.
RedHat series
Redhat should be said to be the most widely used Linux version in China. Some people even equate Redhat with Linux. Therefore, this version is characterized by a large number of users and a lot of information. The implication is that if you don’t understand something, it is easy to find someone to ask. Moreover, the general Linux tutorials on the Internet use Redhat as an example. By the way, the ones used for teaching are generally RedHat. The package management method of the Redhat series uses the YUM package management method based on RPM packages, and the package distribution method is compiled binary files.
Redhat series, including RHEL (Redhat Enterprise Linux, also known as Redhat Advance Server, paid version), Fedora Core (developed from the original Redhat desktop version, free version), CentOS (RHEL's community Clone version, free).
In terms of stability, RHEL and CentOS have very good stability and are suitable for server use. However, Fedora Core has poor stability and is best used only for desktop applications.
Debian Series
Debian, or Debian series, includes Debian and Ubuntu, etc.
Debian is a model of community-based Linux and is the Linux system that most follows GNU specifications so far. Debian was first created by Ian Murdock in 1993 and is divided into three version branches: stable, testing and unstable. Among them, unstable is the latest test version, which includes the latest software packages, but it also has relatively many bugs and is suitable for desktop users. The testing version has been tested in unstable, is relatively stable, and supports many new technologies (such as SMP, etc.). Stable is generally only used on servers. Most of the above software packages are relatively outdated, but the stability and security are very high. The most distinctive feature of Debian is the apt-get/dpkg package management method. In fact, Redhat's YUM also imitates Debian's APT method, but among binary file distribution methods, APT should be the best. Debian’s information is also very rich, and there are many supportive communities. If you have any questions, there are places to go.
Ubuntu is not strictly an independent distribution. Ubuntu is based on the unstable version of Debian and is enhanced. It can be said that Ubuntu is a nearly perfect Linux desktop system that has all the advantages of Debian and its own enhanced advantages. Depending on the desktop system chosen, there are three versions to choose from, Gnome-based Ubuntu, KDE-based Kubuntu and Xfc-based Xubuntu. It is characterized by a very friendly interface, easy to use, and comprehensive hardware support. It is the most suitable Linux distribution for desktop systems.
GentooGentoo, the great Gentoo is the youngest distribution in the Linux world. Because of its youth, it can absorb the advantages of all distributions before it. This is one of the reasons why Gentoo is called the most perfect Linux distribution. Gentoo was originally created by Daniel Robbins (one of the developers of FreeBSD), and the first stable version was released in 2002. Because developers are familiar with FreeBSD, Gentoo has a well-known ports system that is comparable to FreeBSD - the Portage package management system. Unlike package management systems that distribute binary files such as APT and YUM, Portage is distributed based on source code and must be compiled before running. It is relatively slow for large software, but because all software is compiled on the local machine, in After various customized compilation parameter optimizations, the machine's hardware performance can be maximized. Gentoo is the most complex to install among all Linux distributions, but it is also the easiest to manage after installation, and it is also the fastest to run under the same hardware environment.
FreeBSDIt needs to be emphasized that FreeBSD is not a Linux system, but a considerable part of the user groups of FreeBSD and Linux overlap, and the hardware supported by both The environment is also relatively consistent, and the software used is also relatively similar, so FreeBSD can be compared as a Linux version. FreeBSD has two branches: stable and current. As the name suggests, stable is a stable version, while current is a beta version that adds new technologies. FreeBSD uses the Ports package management system, which is similar to Gentoo. It is distributed based on source code and must be compiled on the local machine before it can run. However, the Ports system is not as easy to use as the Portage system and is slightly more complicated to use. The biggest feature of FreeBSD is its stability and efficiency, making it the best choice as a server operating system. However, its hardware support is not as complete as Linux, so it is not suitable as a desktop system.
Linux distribution version selection suggestionsIf you just need a desktop system, and you don’t want to use piracy, nor do you want to spend a lot of money on commercial software, then you need a Linux distribution suitable for desktop use. If you don’t want to customize anything yourself, If you don’t want to waste too much time on the system, it’s very simple. You can choose one of ubuntu, kubuntu and xubuntu according to your own preferences. The difference between the three is just the desktop program. If you need a desktop system, want to customize your Linux system very flexibly, want your machine to run more happily, and don’t mind wasting a little time on Linux system installation, then your only choice is Gentoo, enjoy it Enjoy the freedom Gentoo brings! If what you need is a server system, and you are very tired of various Linux configurations and just want a more stable server system, then your best choice is CentOS. After the installation is complete, you can simply configure it. Can provide very stable service. If what you need is a rock-solid and extremely stable server system, then your only choice is FreeBSD. If you need a stable server system, want to delve into all aspects of Linux, and want to customize a lot of content yourself, then I recommend you use Gentoo.

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

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.

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

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 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

To restart the Apache server, follow these steps: Linux/macOS: Run sudo systemctl restart apache2. Windows: Run net stop Apache2.4 and then net start Apache2.4. Run netstat -a | findstr 80 to check the server status.

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
