## Install Apache Gravitino from scratch
+### Prerequisites
+
+If you have not installed Java, install it and configure the `JAVA_HOME`
environment variable. After installation, you can run the
`${JAVA_HOME}/bin/java -version` command to check the Java version.
+
:::note
-Apache Gravitino supports running on Java 8, 11, and 17. Make sure you have
Java installed and
-`JAVA_HOME` configured correctly. To confirm the Java version, run the
-`${JAVA_HOME}/bin/java -version` command.
+Gravitino supports running on Java 8, 11, and 17.
:::
-The Gravitino package comprises both the Gravitino server and the Gravitino
Iceberg REST server. You can manage these servers independently or run them
concurrently on a single server.
-
-### Get the Apache Gravitino binary distribution package
-
-Before installing Gravitino, make sure you have the Gravitino binary
distribution package. You can download the latest Gravitino binary distribution
package from [GitHub](https://github.com/apache/gravitino/releases).
-You can also build it yourself by following the instructions in [How to Build
Gravitino](./how-to-build.md).
-
- - If you build Gravitino yourself using the `./gradlew compileDistribution`
command, you can find the Gravitino binary distribution package in the
`distribution/package` directory.
-
- - If you build Gravitino yourself using the `./gradlew assembleDistribution`
command, you can get the compressed Gravitino binary distribution package with
the name `gravitino-<version>-bin.tar.gz` in the `distribution` directory with
sha256 checksum file `gravitino-<version>-bin.tar.gz.sha256`.
-
-The Gravitino binary distribution package contains the following files:

+### Get the Gravitino package
+
+The Gravitino package comprises the Gravitino server and the Gravitino Iceberg
REST server. You can manage these servers independently or run them
concurrently on a single server.
+
+1. Download the latest Gravitino package from
[GitHub](https://github.com/apache/gravitino/releases).
+
+ :::note
+ You can also build Gravitino by following the instructions in [How to
Build Gravitino](./how-to-build.md).
-#### Initialize the RDBMS (Optional)
+ - If you build Gravitino using the `./gradlew compileDistribution`
command, you can find the Gravitino package in the `distribution/package`
directory.
-If you want to use the relational backend storage, you need to initialize the
RDBMS first. For the details on initializing the RDBMS, please check [How to
use relational backend storage](./how-to-use-relational-backend-storage.md).
+ - If you build Gravitino using the `./gradlew assembleDistribution`
command, you can get the compressed Gravitino package with the name
`gravitino-<version>-bin.tar.gz` in the `distribution` directory with sha256
checksum file `gravitino-<version>-bin.tar.gz.sha256`.
+ :::
-#### Configure the Apache Gravitino server
+2. Extract the Gravitino package and you should have these directories and
files:
-The Gravitino server configuration file is `conf/gravitino.conf`. You can
configure the Gravitino server by modifying this file. Basic configurations
have already been added to this file. All the configurations are listed in
[Gravitino Server Configurations](./gravitino-server-config.md).

-#### Configure the Apache Gravitino server log
+### Initialize the RDBMS (Optional)
-The Gravitino server log configuration file is `conf/log4j2.properties`.
Gravitino uses Log4j2 as the Logging system. You can
[Log4j2](https://logging.apache.org/log4j/2.x/) to do the log configuration.
+If you want to use the relational backend storage, you need to initialize the
RDBMS. For details on initializing the RDBMS, see [How to use relational
backend storage](./how-to-use-relational-backend-storage.md).
-#### Configure the Apache Gravitino server environment
+### Configure the Gravitino server
-The Gravitino server environment configuration file is
`conf/gravitino-env.sh`. Gravitino exposes several environment variables. You
can modify them in this file.
+The `conf/gravitino.conf` file provides basic configurations of the Gravitino
server. To configure the Gravitino server, you can update this file. For a full
list of the Gravitino server configurations, see [Gravitino Server
Configurations](./gravitino-server-config.md).
-#### Configure Apache Gravitino catalogs
+### Configure the Gravitino server log
-Gravitino supports multiple catalogs. You can configure the catalog-level
configurations by modifying the related configuration file in the
`catalogs/<catalog-provider>/conf` directory. The configurations you set here
apply to all the catalogs of the same type you create.

configurations. To configure the Gravitino server log, you can update this file.
-For example, if you want to configure the Hive catalog, you can modify the
file `catalogs/hive/conf/hive.conf`. The detailed configurations are listed in
the specific catalog documentation.

`catalogs/hive/conf/hive.conf` file provides configurations for the Hive
catalog. The configurations you set in the catalog configuration file will
apply to all the catalogs of the same type that you created. For detailed
configurations about each catalog, see related catalog documentation.

-Gravitino supports passing in catalog-specific configurations if you add
`gravitino.bypass.`. For example, if you want to pass in the HMS-specific
configuration `hive.metastore.client.capability.check` to the underlying Hive
client in the Hive catalog, add the `gravitino.bypass.` prefix.
