Logging In to a Linux ECS from a macOS Server
Scenario
This section describes how to log in to a Linux ECS from a macOS server.
Prerequisites
- The target ECS is running.
- You have obtained the username and password for logging in to the ECS. If the password is forgotten, reset the password by referring to Resetting the Password for Logging In to an ECS on the Management Console.
- You have bound an EIP to the ECS. For details, see Binding an EIP.
- Port 22 is allowed in the inbound direction of the security group which the ECS belongs to. For details, see Configuring Security Group Rules.
Procedure
You can log in to the Linux ECS through the terminal included in the macOS.
- Using an SSH password
- Open the terminal of the macOS and run the following command to log in to the ECS:
ssh Username@EIP
If a public image is used (including CoreOS), the username is root.
- Open the terminal of the macOS and run the following command to log in to the ECS:
- Using an SSH key
- Open the terminal of the macOS and run the following command to change permissions. The following operations use private key file kp-123.pem as an example. Replace it with your actual private key file.
chmod 400 /path/kp-123.pem
In the preceding command, path refers to the path where the key file is saved.
- Run the following command to log in to the ECS:
ssh -i /path/kp-123.pem Username@EIP
- The username is core for a CoreOS public image.
- The username is root for a non-CoreOS public image.
- Open the terminal of the macOS and run the following command to change permissions. The following operations use private key file kp-123.pem as an example. Replace it with your actual private key file.
Follow-up Procedure
- After logging in to the ECS using the SSH key, you can set a password (by using the passwd command) to log in to the ECS using VNC.
