How to configure Go path in VSCode?

Setting GOPATH when configuring the Go environment is key, especially in VSCode, it ensures that the project structure is clear and dependency management is smooth. 1. First, confirm whether the Go environment is installed correctly, run goenv to view GOPATH and GOROOT. If you use Go1.11 and gomodules, the GOPATH function will be weakened but may still be dependent on some tools. 2. Install the official Go plug-in and configure the workspace, open the .go file and install auxiliary tools, and enable Go:UseLanguageServer by setting to reduce dependence on GOPATH. 3. If you need to customize GOPATH, you can add GOPATH and PATH through global settings or shell configuration files.

Python CI/CD Pipeline Automation

Using Python to automate CI/CD requires clearing the process and matching tools. 1. Trigger the CI process through Git, and use GitHubActions, GitLabCI and other tool configuration files to define the construction steps, such as running the test when submitting the code. 2. Automate the testing process, including unit testing (pytest/unittest), type check (mypy), code style check (black/flake8), and security check (bandit). 3. When deploying automation, push it to the test environment first, and use PyPI release, server deployment (Fabric/Ansible), Docker containerization, or CI tool trigger scripts to implement CDs. Through these steps

Use sudoss-tuln to view all listened TCP and UDP ports, which is the most recommended method; 2. If you need to be compatible with old systems, you can install net-tools and use sudonestat-tuln to achieve similar functions; 3. Use sudolsof-i: port number or sudolsof-iTCP-sTCP:LISTEN to view specific ports or all TCP listening processes and their associated services; 4. Run sudofirewall-cmd--list-all or su

What are the advantages of a Linux server over a Windows server?

Linux servers have obvious advantages over Windows servers in terms of flexibility, cost and performance. First, Linux can provide better performance on low-end hardware because it occupies less resources and can choose from lightweight systems such as AlpineLinux; second, it provides higher customization and control rights, and supports replacement of package managers and service components; third, built-in command line tools and scripts support greatly simplifying automation tasks; fourth, its open-source security and stability design ensures long-term operation and policy control; finally, although Windows has advantages in specific scenarios such as .NET applications, Linux is still the preferred solution for web hosting, cloud computing and back-end services.

How to Configure UFW Firewall on an Ubuntu Linux Server

First make sure to allow SSH access, then enable UFW and set the default policy to deny all inbound and all outbound traffic, then open the necessary service ports (such as SSH, HTTP, HTTPS), optionally limit access to the source IP, use speed limit rules to prevent brute force cracking, and verify the configuration through ufwstatus, and finally avoid resetting the firewall.

Setting Up and Using Multiple Git Accounts on One Machine

Use independent SSH keys: Generate an exclusive SSH key (such as personal and work) for each Git account and add it to SSHagent; 2. Configure the SSHconfig file: Set a custom host for different accounts in ~/.ssh/config (such as github.com-personal and github.com-work) to bind the corresponding key; 3. Update the repository remote URL: Use a custom host when cloning or setting remote to ensure that the correct key is automatically matched; 4. Set Git user information according to the repository: Delete the global user.name/email configuration, and execute gitconfig settings separately in each project.

How to Use `grep` for Powerful Pattern Matching in Linux

grep is the core tool used for text search in Linux, which can quickly find content through pattern matching; its basic syntax is grep[options]PATTERN[FILE...], for example, grep"error"/var/log/syslog can find lines containing "error", which is case sensitive by default, and case can be ignored using the -i option, such as grep-i"error"/var/log/syslog; supports regular expressions, 1. Use ^ to match the beginning of the line, such as grep"^Failed"/var/log/a

How to update themes using WP-CLI

It is actually not difficult to update WordPress themes, and using WP-CLI is more efficient and convenient. 1.
