Configuring Password-free Login to an ECS

This section describes how to configure an ECS to enable password-free login to it.

$: indicates performing an operation as a common user.

#: indicates performing an operation as an administrator.

Run the sudo su command to switch from a common user to an administrator.

An ECS has been created successfully and an EIP has been bound to it.

Use PuTTY and a key pair to log in to an ECS in the cluster.
Run the following command to disable user logout upon system timeout:
# TMOUT=0
Copy the ECS private key file (for example *.pem) to the .ssh directory and name it as id_rsa.
$ cd ~/.ssh

$ mv *.pem id_rsa
Run the following command to configure permissions of the key file:
$ sudo chmod 600 id_rsa
Run the following command to query the host name:
# hostname
Run the following command to add the private network IP address and name of the host:
# vi /etc/hosts

An example command is as follows:

192.168.0.1 ecs-ff-0001
Run the following commands to log in to the node using SSH and check whether you can log in to the ECS without a password:
For example, if the hostname is hostname1, run the following commands:

$ ssh localhost

$ ssh hostname1
