How to connect to linux remotely
Linux is mostly used in servers, and servers cannot be placed in offices like PCs. They are placed in IDC computer rooms, so I usually log in to the Linux system through remote login.
In the Linux system, the remote login function is implemented through the ssh service. By default, the ssh service opens port 22, and when we install the system, this service is already installed and started at boot. So we can directly log in to the Linux system remotely without any additional configuration. (Recommended learning: linux operation and maintenance)
The configuration file of the ssh service is /etc/ssh/sshd_config. You can modify this configuration file to achieve the ssh service you want. . For example, you can change the startup port to 36000.
If you are running a Windows operating system, Linux remote login requires an additional terminal software to be installed on our machine. Currently, the more common terminal login software includes SecureCRT, Putty, SSH Secure Shell, etc. Many friends like to use SecureCRT because of its powerful functions, while the author likes to use Putty just because of its compact size and very beautiful color display. No matter which client software you use, there is only one ultimate goal, which is to log in to the Linux server remotely. There are many free versions of these software online. You can download one and try it out. The author below introduces how to use Putty to log in to a remote Linux server.
If you downloaded putty, please double-click putty.exe and the following window will pop up. The putty used by the author is the English version. If you feel that the English version is awkward, you can download the Chinese version.
Because it is a remote login, the server you want to log in to must have an IP or host name. Please enter the IP address of the remote server you want to log into in the box below Host Name (or IP address) (if your Linux does not have an IP yet, please set an IP yourself. Please find out how to set it up in the subsequent chapters), and then press Enter.
At this time, we are prompted to enter the user name to log in.
Enter root and press Enter, then enter the password to log in to the remote Linux system.
The above is the detailed content of How to connect to linux remotely. For more information, please follow other related articles on the PHP Chinese website!

Unable to log in to mysql as root
Apr 08, 2025 pm 04:54 PM
The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.
C language conditional compilation: a detailed guide for beginners to practical applications
Apr 04, 2025 am 10:48 AM
C language conditional compilation is a mechanism for selectively compiling code blocks based on compile-time conditions. The introductory methods include: using #if and #else directives to select code blocks based on conditions. Commonly used conditional expressions include STDC, _WIN32 and linux. Practical case: Print different messages according to the operating system. Use different data types according to the number of digits of the system. Different header files are supported according to the compiler. Conditional compilation enhances the portability and flexibility of the code, making it adaptable to compiler, operating system, and CPU architecture changes.
【Rust Self-study】Introduction
Apr 04, 2025 am 08:03 AM
1.0.1 Preface This project (including code and comments) was recorded during my self-taught Rust. There may be inaccurate or unclear statements, please apologize. If you benefit from it, it's even better. 1.0.2 Why is RustRust reliable and efficient? Rust can replace C and C, with similar performance but higher security, and does not require frequent recompilation to check for errors like C and C. The main advantages include: memory security (preventing null pointers from dereferences, dangling pointers, and data contention). Thread-safe (make sure multi-threaded code is safe before execution). Avoid undefined behavior (e.g., array out of bounds, uninitialized variables, or access to freed memory). Rust provides modern language features such as generics
What are the 5 basic components of Linux?
Apr 06, 2025 am 12:05 AM
The five basic components of Linux are: 1. The kernel, managing hardware resources; 2. The system library, providing functions and services; 3. Shell, the interface for users to interact with the system; 4. The file system, storing and organizing data; 5. Applications, using system resources to implement functions.
How to solve mysql cannot be started
Apr 08, 2025 pm 02:21 PM
There are many reasons why MySQL startup fails, and it can be diagnosed by checking the error log. Common causes include port conflicts (check port occupancy and modify configuration), permission issues (check service running user permissions), configuration file errors (check parameter settings), data directory corruption (restore data or rebuild table space), InnoDB table space issues (check ibdata1 files), plug-in loading failure (check error log). When solving problems, you should analyze them based on the error log, find the root cause of the problem, and develop the habit of backing up data regularly to prevent and solve problems.
Where is the C language function library? How to add the C language function library?
Apr 03, 2025 pm 11:39 PM
The C language function library is a toolbox containing various functions, which are organized in different library files. Adding a library requires specifying it through the compiler's command line options, for example, the GCC compiler uses the -l option followed by the abbreviation of the library name. If the library file is not under the default search path, you need to use the -L option to specify the library file path. Library can be divided into static libraries and dynamic libraries. Static libraries are directly linked to the program at compile time, while dynamic libraries are loaded at runtime.
Can mysql run on android
Apr 08, 2025 pm 05:03 PM
MySQL cannot run directly on Android, but it can be implemented indirectly by using the following methods: using the lightweight database SQLite, which is built on the Android system, does not require a separate server, and has a small resource usage, which is very suitable for mobile device applications. Remotely connect to the MySQL server and connect to the MySQL database on the remote server through the network for data reading and writing, but there are disadvantages such as strong network dependencies, security issues and server costs.
Solutions to the errors reported by MySQL on a specific system version
Apr 08, 2025 am 11:54 AM
The solution to MySQL installation error is: 1. Carefully check the system environment to ensure that the MySQL dependency library requirements are met. Different operating systems and version requirements are different; 2. Carefully read the error message and take corresponding measures according to prompts (such as missing library files or insufficient permissions), such as installing dependencies or using sudo commands; 3. If necessary, try to install the source code and carefully check the compilation log, but this requires a certain amount of Linux knowledge and experience. The key to ultimately solving the problem is to carefully check the system environment and error information, and refer to the official documents.
