Configuring Ranger

Describes how to set up Ranger services and run the configuration script.

Use these steps:

Set up Ranger services:
1. In the install.properties file in the Ranger Admin home directory (/opt/mapr/ranger/ranger-<version>/ranger-admin/install.properties), modify the properties using one of the following options:
  - If you have skipped Step 1. and 2. in Installing Ranger procedure, modify the following properties:
```
db_root_user=root 
db_root_password=<root_db_password> 

db_name=<created_db_name> 
db_user=<created_db_user> 
db_password=<created_db> 

rangerAdmin_password=<min_8_char_with_numeric_and_min_one_capital> 
rangerTagsync_password=<min_8_char_with_numeric_and_min_one_capital> 
rangerUsersync_password=<min_8_char_with_numeric_and_min_one_capital> 
keyadmin_password=<min_8_char_with_numeric_and_min_one_capital>
```
  - If you have performed Step 1. and 2. in Installing Ranger procedure, modify the following properties:
```
db_name=<created_db_name> 
db_user=<created_db_user> 
db_password=<created_db> 

rangerAdmin_password=<min_8_char_with_numeric_and_min_one_capital> 
rangerTagsync_password=<min_8_char_with_numeric_and_min_one_capital> 
rangerUsersync_password=<min_8_char_with_numeric_and_min_one_capital> 
keyadmin_password=<min_8_char_with_numeric_and_min_one_capital>
```
  Later you will use the keyadmin_password to log on to the Ranger web UI.
2. Run the setup script:
```
sudo /opt/mapr/ranger/ranger-<version>/ranger-admin/setup.sh
```
  The /ranger-admin/setup.sh script copies some basic ugsync-related properties to the ugsync install.properties and then runs the ugsync script. However, to custom configure ugsync, you must edit /opt/mapr/ranger/ranger-2.3.0/ranger-usersync/install.properties and then run sudo /opt/mapr/ranger/ranger-2.3.0/ranger-usersync/setup.sh.
Run the configuration script as root. Running configure.sh restarts the Ranger Admin and Ranger UserSync services:
```
/opt/mapr/server/configure.sh -R
```
