If your data center does not provide unlimited internet access and has a proxy server in place to control HTTP, HTTPS or FTP traffic, you may need to configure your management nodes to be able to access external resources; for example for the purpose of performing software updates.
The following instructions must be followed for each of the two management nodes in your environment.
Adding Proxy Settings for a Management Node
Gain command line access to the management node. Usually this is achieved using SSH and logging in as the root user with the global Oracle Private Cloud Appliance password.
Use the CLI, as described in Chapter 3, The Oracle Private Cloud Appliance Command Line Interface (CLI), to view or modify your proxy settings. The CLI safely reads and edits the
/etc/ovca.conf
file, to prevent the possibility of configuration file corruption.To view the current values for the configurable settings in the configuration file run the CLI as follows:
# pca-admin show system-properties
To set an HTTP proxy:
# pca-admin set system-property http_proxy http://
IP
:PORT
Where
IP
is the IP address of your proxy server, andPORT
is the TCP port on which it is listening.CautionIf your proxy server expects a user name and password, these should be provided when the proxy service is accessed. Do not specify credentials as part of the proxy URL, because this implies that you send sensitive information over a connection that is not secure.
To set an HTTPS proxy:
# pca-admin set system-property https_proxy https://
IP
:PORT
To set an FTP proxy:
# pca-admin set system-property ftp_proxy ftp://
IP
:PORT
Setting any single parameter automatically rewrites the configuration file and the proxy settings become active immediately.
