# Configuring the Liferay DXP Service¶

There are several methods available to configure Liferay DXP: through the in DXP System Settings and through the use of config and property files. DXP property and configuration files for your Liferay DXP instance in DXP Cloud are deployed by being placed inside of one of the configs/ folders in the Liferay DXP service directory in your repository.

liferay
├── configs
│   ├── common
│   ├── dev
│   ├── local
│   ├── prd
│   └── uat
└── LCP.json


With the exception of the common/ directory, changes added to an environment-specific folder (e.g., dev, uat, prod) will only be propagated when deploying to the corresponding environment. Changes added to a common/ directory will always be deployed, regardless of the target deployment environment. This applies to all subfolders within the configs/ directory, for all services.

Note

If you are using version 3.x.x services, then these configuration files instead belong in the appropriate lcp/liferay/config/{ENV}/ folder. See Understanding Service Stack Versions_ for more information on checking the version.

## Portal Properties¶

Portal properties are properties saved in a portal-ext.properties file. They are used to configure your Liferay DXP environment.

For an on-premises Liferay DXP instance, this file belongs inside of $LIFERAY_HOME. When using Liferay DXP Cloud, place portal properties file into the appropriate configs/{ENV}/ folder(s) for them to be copied into $LIFERAY_HOME for the Liferay DXP instance on deployment.

For example, the properties in a dev environment will result from the property files in the configs/common directory and the properties in the configs/dev directory. If any files have the same name, the file in the environment specific directory will overwrite the file from the common directory.

Note

If you are using version 3.x.x services, then these configuration files instead belong in the appropriate lcp/liferay/config/{ENV}/ folder. See Understanding Service Stack Versions for more information on checking the version.

### Splitting Portal Properties into Multiple Files¶

By default, Liferay will only read properties directly from the portal-ext.properties file, but it can be helpful to organize your properties into different files in your repository, such as environment-specific files. You can define additional files to override your portal properties:

• portal-all.properties: Contains the properties that change Liferay DXP across environments

• portal-env.properties: Contains the properties that only affect the current environment (for example, credentials and URL endpoints for external services that differ from environment to environment)

To use these files, the portal-ext.properties file must explicitly import portal-all.properties and portal-env.properties using the include-and-override property:

include-and-override=/opt/liferay/portal-all.properties
include-and-override=/opt/liferay/portal-env.properties


You can then organize your properties with the following structure:

liferay
├── configs
│   ├── common
│   │   ├── portal-ext.properties
│   │   └── portal-all.properties
│   ├── dev
│   │   └── portal-env.properties
│   ├── local
│   │   └── portal-env.properties
│   ├── prd
│   │   └── portal-env.properties
│   └── uat
│       └── portal-env.properties
└── LCP.json


The portal-ext.properties and portal-all.properties files are shared across all environments. You can add any shared properties there and add environment specific properties in each respective portal-env.properties file. For more information, see Portal Property Priority.

Note

Portal properties may also be defined as environment variables. See the environment variables reference for more information.

## OSGi Configurations¶

OSGi configurations (.cfg or .config files) are used to configure OSGi components in Liferay DXP.

These configuration files belong in the osgi/configs/ folder inside of \$LIFERAY_HOME. When using Liferay DXP Cloud, place these files into the appropriate configs/{ENV}/osgi/ folder(s) for them to be copied into /osgi/configs for the Liferay DXP instance on deployment.

Note

If you are using version 3.x.x services, then OSGi configuration files instead belong in the appropriate config/{ENV}/ folder within the Liferay service directory. See Understanding Service Stack Versions for more information on checking the version.

## Tomcat Configurations¶

Configure your Liferay service’s Tomcat server by deploying files in the appropriate environment’s liferay/configs/{ENV} folder to override the configuration files. For example, you can override the {TOMCAT HOME}/conf/web.xml file in your Liferay container’s file system by placing the customized file in the appropriate liferay/configs/{ENV}/tomcat/conf/ folder in your repository and deploying the changes.

Note

Two tomcat folders exist in the Liferay container in DXP Cloud: a generic tomcat folder, and a versioned folder (tomcat-x.x.x). The tomcat folder has a symbolic link to the versioned tomcat-x.x.x folder, so overriding a file in the generic tomcat folder ensures the new file reflects in both folders.

Warning

Keep in mind when overriding the default Tomcat configuration that the Liferay service in DXP Cloud exists in a closed network on the Cloud platform. Some network configurations that can be changed in an on-premises Liferay installation cannot be changed from the default values in a Cloud environment, or it may cause issues in your environment.

## Environment Variables¶

The Liferay service in DXP Cloud uses environment variables (or secrets) in place of some configurations that are done differently with an on-premises instance, such as JVM memory settings or database connection settings. Environment variables can also be used to override or replace portal properties.
