4.10.3 Connecting to a remote host

To configure a cluster, you must configure the local host and remote host to connect with SSH. On the local host, you can establish the SSH connection using the setup-ssh subcommand of the asadmin utility command.

Prerequisites

The domain administration server (DAS) is running.
Application Server has been set up on the localhost.
The remote host is running.
Installation of Application Server is complete on the remote host.
The remote host and local host can be connected using SSH.

Intended users

System engineers

Procedure

To resolve the name of the host with the DAS (local host) on a remote host, edit the host file.
On the local host, create a password file.
```
AS_ADMIN_SSHPASSWORD=remote_host_password
```
To create the code key (SSL key), run the setup-ssh subcommand of the asadmin utility command on the localhost.
```
asadmin --passwordfile password_file_path setup-ssh 
--sshuser remote_host_SSH_user_name remote_host_name
```
When this command is run, the result is displayed as follows:
```
Command setup-ssh executed successfully.
```
To set an alias for the password, run the create-password-alias subcommand of the asadmin utility command on the local host.
```
asadmin create-password-alias password_alias_name
```
Specify the password of the remote host when it is requested.
When this command is run, the result is displayed as follows:
```
Command create-password-alias executed successfully.
```
Restart the domain administration server.
```
asadmin restart-domain
```
When this command is run, the result is displayed as follows:
```
Command restart-domain executed successfully.
```
Edit the password file available on the local host created in Step 2.
```
AS_ADMIN_SSHPASSWORD=${ALIAS=password_alias_name}
```
For each remote host to be configured as a distribution location of a request, repeat the procedure from steps 1 through 6 on each remote host.
