Method 1: Official AWS CLI Installer (Recommended) The official AWS CLI installer is the most reliable and recommended method for installing AWS CLI v2 on Linux systems. Step 1: Download the AWS CLI Installer ```bash For x86_64 architecture curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip" For ARM64 architecture (e.g., ARM-based EC2 instances) curl "https://awscli.amazonaws.com/awscli-exe-linux-aarch64.zip" -o "awscliv2.zip" ``` Step 2: Extract the Installer ```bash unzip awscliv2.zip ``` Step 3: Run the Installation ```bash System-wide installation (requires sudo) sudo ./aws/install Custom installation path sudo ./aws/install --bin-dir /usr/local/bin --install-dir /usr/local/aws-cli User-specific installation (no sudo required) ./aws/install -i ~/.local/aws-cli -b ~/.local/bin ``` Step 4: Verify Installation ```bash aws --version ``` Expected output: ``` aws-cli/2.x.x Python/3.x.x Linux/x.x.x exe/x86_64.distro ``` Step 5: Clean Up Installation Files ```bash rm -rf aws awscliv2.zip ``` Method 2: Package Manager Installation Ubuntu/Debian Systems Using apt Package Manager ```bash Update package index sudo apt update Install AWS CLI sudo apt install awscli Verify installation aws --version ``` Using snap (Ubuntu) ```bash Install AWS CLI via snap sudo snap install aws-cli --classic Verify installation aws --version ``` CentOS/RHEL/Fedora Systems Using yum (CentOS 7/RHEL 7) ```bash Install EPEL repository sudo yum install epel-release Install AWS CLI sudo yum install awscli Verify installation aws --version ``` Using dnf (Fedora/CentOS 8+/RHEL 8+) ```bash Install AWS CLI sudo dnf install awscli Verify installation aws --version ``` Amazon Linux ```bash Amazon Linux 2 sudo yum install awscli Amazon Linux 2023 sudo dnf install awscli ``` Method 3: pip Installation Installing with pip3 ```bash Install for current user pip3 install awscli --user System-wide installation sudo pip3 install awscli Install specific version pip3 install awscli==2.x.x --user ``` Adding to PATH (User Installation) If you installed AWS CLI with `--user` flag, add the following to your shell profile: ```bash Add to ~/.bashrc or ~/.zshrc export PATH=$PATH:~/.local/bin Reload your shell configuration source ~/.bashrc ``` Method 4: Docker Installation Running AWS CLI in Docker ```bash Pull the official AWS CLI Docker image docker pull amazon/aws-cli Run AWS CLI commands docker run --rm -it amazon/aws-cli --version Create an alias for easier usage echo 'alias aws="docker run --rm -it -v ~/.aws:/root/.aws amazon/aws-cli"' >> ~/.bashrc source ~/.bashrc ``` Initial Configuration After successful installation, configure AWS CLI with your credentials and preferences. Basic Configuration ```bash aws configure ``` You'll be prompted to enter: - AWS Access Key ID: Your access key - AWS Secret Access Key: Your secret key - Default region name: e.g., us-east-1 - Default output format: json, yaml, text, or table Configuration Files AWS CLI stores configuration in two files: - `~/.aws/credentials` - Contains access keys - `~/.aws/config` - Contains configuration settings Multiple Profiles Set up multiple profiles for different AWS accounts or roles: ```bash Configure a named profile aws configure --profile production Use a specific profile aws s3 ls --profile production Set default profile export AWS_PROFILE=production ``` Environment Variables Configure AWS CLI using environment variables: ```bash export AWS_ACCESS_KEY_ID=your_access_key export AWS_SECRET_ACCESS_KEY=your_secret_key export AWS_DEFAULT_REGION=us-east-1 export AWS_DEFAULT_OUTPUT=json ``` Verification and Testing Test Basic Functionality ```bash List S3 buckets aws s3 ls Get caller identity aws sts get-caller-identity List EC2 instances aws ec2 describe-instances Check AWS CLI help aws help ``` Version Management ```bash Check current version aws --version List installed versions (if multiple) ls -la /usr/local/bin/aws* ``` Updating AWS CLI Updating Official Installer Version ```bash Download latest version curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip" unzip awscliv2.zip Update installation sudo ./aws/install --bin-dir /usr/local/bin --install-dir /usr/local/aws-cli --update Clean up rm -rf aws awscliv2.zip ``` Updating Package Manager Versions ```bash Ubuntu/Debian sudo apt update && sudo apt upgrade awscli CentOS/RHEL sudo yum update awscli Fedora sudo dnf update awscli ``` Updating pip Versions ```bash Update to latest version pip3 install --upgrade awscli --user Update system-wide sudo pip3 install --upgrade awscli ``` Common Issues and Troubleshooting Issue 1: Command Not Found Problem: `aws: command not found` after installation Solutions: ```bash Check if AWS CLI is in PATH echo $PATH Find AWS CLI location which aws whereis aws Add to PATH manually export PATH=$PATH:/usr/local/bin echo 'export PATH=$PATH:/usr/local/bin' >> ~/.bashrc ``` Issue 2: Permission Denied Problem: Permission errors during installation Solutions: ```bash Use sudo for system-wide installation sudo ./aws/install Or install for current user only ./aws/install -i ~/.local/aws-cli -b ~/.local/bin ``` Issue 3: SSL Certificate Errors Problem: SSL certificate verification failures Solutions: ```bash Update CA certificates sudo apt update && sudo apt install ca-certificates For CentOS/RHEL sudo yum update ca-certificates Temporary workaround (not recommended for production) aws configure set default.ca_bundle /etc/ssl/certs/ca-certificates.crt ``` Issue 4: Python Version Conflicts Problem: Incompatible Python versions Solutions: ```bash Check Python version python3 --version Install specific Python version (Ubuntu) sudo apt install python3.8 python3.8-pip Use specific pip version python3.8 -m pip install awscli --user ``` Issue 5: AWS CLI v1 vs v2 Conflicts Problem: Multiple versions causing conflicts Solutions: ```bash Remove AWS CLI v1 pip3 uninstall awscli Check for multiple installations which -a aws Remove old installations sudo rm /usr/local/bin/aws sudo rm -rf /usr/local/aws-cli ``` Issue 6: Configuration Errors Problem: Invalid credentials or configuration Solutions: ```bash Reconfigure AWS CLI aws configure Check configuration aws configure list Test credentials aws sts get-caller-identity Debug with verbose output aws s3 ls --debug ``` Best Practices and Professional Tips Security Best Practices 1. Use IAM Roles: When possible, use IAM roles instead of access keys 2. Rotate Credentials: Regularly rotate access keys 3. Principle of Least Privilege: Grant minimal required permissions 4. Secure Storage: Protect credential files with appropriate permissions ```bash Set secure permissions for credential files chmod 600 ~/.aws/credentials chmod 600 ~/.aws/config ``` Performance Optimization 1. Configure Output Format: Use appropriate output format for your use case 2. Use Pagination: Handle large result sets efficiently 3. Enable CLI Pager: For better output readability ```bash Configure CLI pager aws configure set cli_pager less Disable pager aws configure set cli_pager "" ``` Automation and Scripting 1. Use Profiles: Organize multiple AWS accounts 2. Environment Variables: Use for CI/CD pipelines 3. Error Handling: Implement proper error handling in scripts ```bash #!/bin/bash Example script with error handling if ! aws sts get-caller-identity > /dev/null 2>&1; then echo "AWS credentials not configured properly" exit 1 fi echo "AWS CLI is properly configured" ``` Version Management 1. Pin Versions: Use specific versions in production 2. Test Updates: Test CLI updates in non-production environments 3. Documentation: Document CLI version requirements Advanced Configuration Custom Configuration Settings ```bash Set custom configuration options aws configure set default.region us-west-2 aws configure set default.output table aws configure set default.cli_pager less Configure retry settings aws configure set max_attempts 10 aws configure set retry_mode adaptive ``` Using Configuration Files Directly Edit `~/.aws/config`: ```ini [default] region = us-east-1 output = json cli_pager = less [profile production] region = us-west-2 output = table role_arn = arn:aws:iam::123456789012:role/ProductionRole source_profile = default ``` Command Completion Enable command completion for better productivity: ```bash For bash echo 'complete -C aws_completer aws' >> ~/.bashrc For zsh echo 'autoload bashcompinit && bashcompinit && complete -C aws_completer aws' >> ~/.zshrc ``` Integration with Development Workflows IDE Integration Most modern IDEs support AWS CLI integration: - VS Code: AWS Toolkit extension - IntelliJ: AWS Toolkit plugin - Vim: AWS CLI integration plugins CI/CD Integration ```yaml Example GitHub Actions workflow name: Deploy to AWS on: [push] jobs: deploy: runs-on: ubuntu-latest steps: - uses: actions/checkout@v2 - name: Configure AWS credentials uses: aws-actions/configure-aws-credentials@v1 with: aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }} aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }} aws-region: us-east-1 - name: Deploy to S3 run: aws s3 sync . s3://my-bucket/ ``` Monitoring and Logging Enable CloudTrail Logging ```bash Create CloudTrail for API call logging aws cloudtrail create-trail --name my-trail --s3-bucket-name my-logs-bucket ``` CLI History and Logging ```bash Enable CLI history aws configure set cli_history enabled View command history aws history list ``` Uninstalling AWS CLI Remove Official Installer Version ```bash Remove AWS CLI v2 sudo rm /usr/local/bin/aws sudo rm /usr/local/bin/aws_completer sudo rm -rf /usr/local/aws-cli ``` Remove Package Manager Versions ```bash Ubuntu/Debian sudo apt remove awscli CentOS/RHEL sudo yum remove awscli Fedora sudo dnf remove awscli ``` Remove pip Versions ```bash Remove user installation pip3 uninstall awscli Remove system-wide installation sudo pip3 uninstall awscli ``` Conclusion and Next Steps You have successfully learned how to install, configure, and troubleshoot AWS CLI on Linux systems.
