By default, the PEM agent is installed in the /home/opt/PEM directory. You can accept the default installation directory, or modify the contents of the Installation Directory field (see Figure 3.45), specifying an alternate installation directory for the PEM agent.
By default, the PEM agent installer places a certificate in ~root/.pem (on Linux) or in the Administrator’s %APPDATA%\pem directory (on Windows). Check the Show advanced options box to indicate that you would like the PEM agent installer to include a dialog that allows you to specify an alternate path for the certificate file.
Check the box next to Register now? to instruct the installer to register the newly installed PEM agent with the PEM server.
Click Next to continue to the PEM Server Installation Details dialog.

Enter the connection details for the PEM server on the PEM server installation details dialog (see Figure 3.46):
Specify the name or IP address of the system on which the PEM database server resides in the Host field. Please note: If the PEM-HTTPD web server and PEM database are hosted on different systems, you must specify the host of the PEM database.
Click Next to continue. The installer will attempt to connect to the server to verify that the details are correct.
Please Note: The PEM server must allow connections from the PEM agent installer. If you encounter a connection error, confirm the connection properties specified on the PEM Server Installation Details dialog are correct, and confirm that the pg_hba.conf file (on the PEM server) will allow a connection to the server described in the error message.

The tree control displayed in the Browser panel of the PEM web interface displays the value entered in the Description field (shown in Figure 3.47) to identify the PEM agent. Specify a descriptive name for the agent, such as the hostname of the machine the agent is installed on, or a name that reflects the host's functionality.
If you checked the Show advanced options checkbox shown in Figure 3.24, the Advanced options dialog opens (shown in Figure 3.48).

By default, the PEM agent installer places the certificate in the /root/.pem directory. Specify an alternate path for the certificate or accept the default and click Next.
The wizard is now ready to install the PEM agent; click Back to amend the installation directory, or Next to continue.
