Running the BDD installer

After you update bdd.conf, you can run the installer to install BDD.

Before you run the installer, you should verify that all of BDD's prerequisites have been satisfied. Specifically, make sure that:

You satisfied all requirements described in Prerequisites.
The bdd user meets the requirements described in OS user requirements.
You are working on the install machine, which is properly set up.
The Studio database (including its username, password, and schema) is set up.
If you are installing with any existing Dgraph databases, the files are on either HDFS or the NFS, and DRAPH_INDEX_DIR points to the correct location.
If you want to run the script in silent mode, you set the environment variables described in Silent installation.
bdd.conf is available and properly configured for your deployment.
The following Hadoop components are running:
- Cloudera Manager/Ambari
- ZooKeeper
- HDFS
- Hive
- Spark on YARN
- YARN
- Hue
- NFS Gateway (if required)

To run the BDD installer:

On the install machine, open a new terminal window and go to the installer directory.
Run the installer:
```
./setup.sh
```
If you are not running the script in silent mode, enter the following information when prompted:
- The username and password for the cluster manager.
- A username and password for the WebLogic Server admin. The password must contain at least 8 characters, one of which must be a number, and can't begin with a number.
- The username and password for the Studio database.
- The password for the Studio admin. This must contain at least 6 characters, one of which must be a non-alphanumeric character.
- The absolute path to the installation source directory, if you didn't set the INSTALLER_PATH property in bdd.conf.

If the script succeeded, BDD is now installed and ready for you to begin working with it. See Post-Installation Tasks to learn more about your installation and how to verify it.

If the script failed, see Troubleshooting a Failed Installation.
