Supports deployment on Linux and Mac OS environments. Windows deployment is not supported.

1. Install MariaDB

Install MariaDB on Linux

On Linux, different distributions have different installation methods:

Ubuntu/Debian

sudo apt update
sudo apt install mariadb-server
sudo systemctl start mariadb
sudo systemctl enable mariadb
sudo mysql_secure_installation

When running the mysql_secure_installation command, follow the prompts for security settings.

CentOS/RHEL

sudo yum update
sudo yum install mariadb-server
sudo systemctl start mariadb
sudo systemctl enable mariadb
sudo mysql_secure_installation

When running the mysql_secure_installation command, follow the prompts for security settings.

Install MariaDB on Mac OS

On Mac OS, you can use Homebrew to install MariaDB:

brew update
brew install mariadb
brew services start mariadb

After installation, you can use the mysql_secure_installation command for security settings.

2. Deploy Public Key

To enable secure, password-less SSH access between the CelerBuild deployment machine and your remote servers, you need to set up public key authentication. Follow these steps:

  1. Generate an SSH key pair (if you haven't already):
ssh-keygen -t rsa -b 4096 -C "[email protected]"

Press Enter to accept the default file location and optionally set a passphrase.

  1. Display and copy the public key:
cat ~/.ssh/id_rsa.pub

Manually select and copy the entire output.

Alternative methods for copying (if needed):

  • On macOS:
pbcopy < ~/.ssh/id_rsa.pub
  • On Linux with graphical interface:
cat ~/.ssh/id_rsa.pub | xclip -selection clipboard

Note: If you encounter the error "Command 'xclip' not found", you can install it using:

sudo apt install xclip  # For Ubuntu/Debian
# or
sudo yum install xclip  # For CentOS/RHEL
  1. Add the public key to the remote server:

a. If you have ssh-copy-id available:

ssh-copy-id user@remote_server

b. If you prefer manual setup or don't have ssh-copy-id:

  • SSH into your remote server:
ssh user@remote_server
  • Create the .ssh directory if it doesn't exist and set permissions:
mkdir -p ~/.ssh
chmod 700 ~/.ssh
  • Open or create the authorized_keys file with vim:
vim ~/.ssh/authorized_keys
  • Press 'i' to enter insert mode, then paste the copied public key.
  • Press 'Esc', then type ':wq' and press Enter to save and exit vim.
  • Set proper permissions for the authorized_keys file:
chmod 600 ~/.ssh/authorized_keys
  1. Test the connection:
ssh user@remote_server

You should be able to log in without entering a password.

Troubleshooting:

  • If you encounter "Permission denied (publickey)" errors, ensure the permissions on both the local and remote .ssh directories and files are correct.
  • For AWS EC2 instances, you may need to use the .pem file for initial access:
ssh -i /path/to/your/key.pem [email protected]

Note: While RSA keys are sufficient for most uses, Ed25519 keys offer enhanced security. Using a strong passphrase is recommended but optional.
