How to Install Full Script of API on a Fresh Linux Server

When you install an api on a fresh server, you need to follow a careful process. You must prepare your environment before you install the full script of the api, especially when deploying on Hong Kong hosting. You should check all dependencies for the api and confirm they work. After you set up the api, you need to verify the api runs as expected. Pay attention to security and harden your system to protect your api from threats, following best practices suitable for Hong Kong hosting environments.

Key Takeaways

• Choose a compatible Linux distribution like Ubuntu or Debian for strong support and easy management.

• Always update your server packages to protect against vulnerabilities before installing the API.

• Verify that all required tools are installed to ensure a smooth API installation process.

• Download the API script from a trusted source and check its integrity to avoid security risks.

• Regularly review logs and test API endpoints to ensure your installation runs smoothly and securely.

Prepare Linux Server

Choose Compatible Distribution

You should start by selecting a linux distribution that matches your needs. Many users prefer Ubuntu or Debian because they offer strong community support and easy package management. CentOS and RHEL also work well for enterprise environments. Make sure your chosen distribution supports the API script you want to install. This step helps avoid compatibility issues later.

Initial Setup and Updates

After you set up your server, you need to update all packages. Keeping your system up to date protects it from known vulnerabilities. For Ubuntu or Debian, run:

• sudo apt update && sudo apt upgrade -y

If you use CentOS or RHEL, use:

• sudo yum update -y

Next, create a new admin user to improve security. Follow these steps:

1. Create a new user called admin with adduser admin.

2. Set a password for the new user.

3. Add the user to the sudo group using adduser admin sudo.

4. Log in as the admin user with ssh admin@<your-server-ip>.

You should always use a non-root user for daily tasks. This practice reduces the risk of accidental system changes.

Install Required Tools

Before you install the API script, check that your server has all the essential tools. These tools help you manage, monitor, and troubleshoot your system:

• curl: Checks if an API is available from the command line.

• make, cron: Handles simple automation tasks.

• ssh, rsync: Connects to other machines and syncs data.

• bat: Displays files with formatting.

• tail: Views the end of large files.

• which: Locates programs in your path.

• grep: Searches through outputs and environment variables.

• ps aux, htop: Monitors running processes.

• rg, fzf: Searches and finds content in files quickly.

Tip: Always verify that each tool is installed before you continue. This step ensures a smooth install process for your API script.

You can also use a package manager to automate installation and updates for these tools. This approach keeps your linux server consistent and secure.

Install Full Script of API

Download Installation Files

You need to download the installation files before you install full script of the api. Start by finding the official source for the api script. Most developers provide a link to download the latest release. You can use curl or wget to download files from the source. Always check the source for authenticity. If you download from an unofficial source, you risk installing malware or outdated scripts.

You can follow these steps to download the api script:

1. Visit the official source for the api.

2. Locate the download section and find the install full script.

3. Use the command line to download the script:

   curl -O https://source.com/api/install.sh
   

4. Check the file integrity by comparing the hash from the source with your downloaded file.

Tip: Downloading from a trusted source protects your server from security threats. Always verify the source before you download.

You may need to download supporting files or dependencies. Some api scripts require you to download configuration files or extra modules from the source. Read the documentation from the source to understand what you need to download.

Make Script Executable

After you download the install full script, you must make it executable. Linux servers require you to set permissions before you run scripts from the source. Use the chmod command to configure the script:

chmod +x install.sh

Making scripts executable creates security risks. You should understand these risks before you configure permissions:

• Script-based malware can bypass traditional security tools like antivirus software.

• These attacks are on the rise due to the ease of embedding scripts in documents, emails, or websites.

Interpreted executables blur the traditional boundaries between data and code, creating additional security challenges for organizations seeking to control executable content.

You must configure permissions carefully. Only allow trusted users to execute the install full script. Never configure scripts from an unknown source.

Run install.sh Script

You can now run the install.sh script to install full script of the api. Use the following command:

./install.sh

The script will configure the api and install dependencies from the source. You may encounter errors during this step. Common errors include:

• Error related to missing Ansible role: community.mongodb.mongodb_repository.

• Command ansible-galaxy collection list fails due to invalid choice error.

• Versioning issues with Ansible on Ubuntu Focal.

• Installation script finishes but no access URL is displayed.

• Docker containers are missing or not running.

• Insufficient permissions leading to “Permission denied” errors.

• Script shows success but web interface is not accessible.

• Docker images failed to pull.

If you see errors, check the configuration files and permissions. Review the source documentation for troubleshooting tips. You may need to configure dependencies or update your server before you install full script.

Note: Running install.sh from the source may require you to configure environment variables or install extra modules. Always read the configuration instructions from the source.

Configure Environment Variables

You must configure environment variables to ensure the api script works as expected. Environment variables control how the script interacts with the source and handles configuration. You can configure these variables in your shell or add them to a configuration file.

Here is a table showing typical environment variables for api scripts:

You should configure each variable based on your source and api requirements. For example, set OUTPUT_DIR to a secure location. Configure API_KEY and API_SECRET with values from your organization. Never share these secrets with untrusted sources.

You can configure environment variables using the export command:

export OUTPUT_DIR=/var/api/output
export API_KEY=your_api_key
export API_SECRET=your_api_secret

You may need to configure other variables depending on the source and api configuration. Always check the documentation from the source for a complete list of variables to configure.

Tip: Proper configuration of environment variables improves security and performance. Review your configuration before you install full script of the api.

You must configure permissions for each variable. Only trusted users should access sensitive configuration data. Store secrets in a secure source and never expose them in public configuration files.

You can configure environment variables in a .env file for easier management. Many api scripts support loading configuration from a source file. This approach simplifies configuration and keeps your install full script organized.

You should review your configuration after you install full script. Test the api to confirm that the configuration works. If you see errors, check your source and configuration files. Update your configuration as needed to match the requirements of the api.

Note: Always configure environment variables before you run the api. Incorrect configuration can cause the api to fail or expose sensitive data to untrusted sources.
