Configure and Start Hue

	Note
	The `su` commands in this section use keywords to represent the Service user. For example, "hdfs" is used to represent the HDFS Service user. If you are using another name for your Service users, you need to substitute your Service user name in each of the `su` commands.

For HDP-2.5.3, use the Hue version shipped with HDP-2.5.3. If you have a previous version of Hue, use the following steps to upgrade Hue.

Migrate hue.ini setting from your old hue.ini configuration file to new hue.ini configuration file.
If you are using the embedded SQLite database, remember to restore your database after upgrade.
To restore the database from a backup, make sure the destination database is empty before copying (if necessary, rename or remove the current destination database), then copy your backup to the destination database. For example:
```
su - hdfs
cd /var/lib/hue
mv desktop.db desktop.db.old 
sqlite3 desktop.db < ~/hue_backup/desktop.bak
exit
```

Synchronize Database

cd /usr/lib/hue
source ./build/env/bin/activate
hue syncdb
deactivate

Start Hue. As a root user, run the following command on the Hue Server:
/etc/init.d/hue start
