Login Overview (Linux)

Scenarios

After an ECS is created, you can log in to the ECS and deploy websites or applications on it. Before logging in to an ECS, you need to establish a connection between the local device and the ECS. The connection method depends on the ECS OS and the tool used by the local device.

This section describes the tools and requirements for connecting to a Linux ECS in different methods. You can select a proper method to log in to a Linux ECS as needed.

Constraints

Only a running ECS can be logged in to.
The username for logging in to a Linux ECS is root.
If the login password is forgotten, reset the password on the ECS console.
