This guide explains how to set up the necessary environment variables for Linqra components.

​
Setting Up Environment Variables

To configure the environment variables on macOS: 
nano ~/.zshrc

​
Required Variables

Below are the essential environment variables grouped by their purpose. These variables should be added to your profile configuration file.

​
Java and Maven Setup

# Java and Maven
export JAVA_HOME=$(/usr/libexec/java_home -v 21)
export PATH=$JAVA_HOME/bin:$PATH
export M2_HOME="/Applications/IntelliJ IDEA CE.app/Contents/plugins/maven/lib/maven3"
export PATH="$M2_HOME/bin:$PATH"

​
SSL Certificate Paths

The default location for SSL certificates is the “keys” folder, but you can specify any location by adjusting the KEY_BASE_DIR.
# Base directory for SSL keys
export KEY_BASE_DIR="/etc/keys"

# Eureka Discovery Server
export EUREKA_KEY_STORE="$KEY_BASE_DIR/eureka-keystore.jks"
export EUREKA_KEY_STORE_PASSWORD="123456"

# API Gateway
export GATEWAY_KEY_STORE="$KEY_BASE_DIR/gateway-keystore.jks"
export GATEWAY_KEY_STORE_PASSWORD="123456"
export GATEWAY_TRUST_STORE="$KEY_BASE_DIR/gateway-truststore.jks"
export GATEWAY_TRUST_STORE_PASSWORD="123456"

# Client Microservices
export CLIENT_KEY_STORE="$KEY_BASE_DIR/client-keystore.jks"
export CLIENT_KEY_STORE_PASSWORD="123456"
export CLIENT_TRUST_STORE="$KEY_BASE_DIR/client-truststore.jks"
export CLIENT_TRUST_STORE_PASSWORD="123456"

​
Authentication Configuration

# OAuth2 Settings
export OAUTH2_REDIRECT_URI="https://localhost:3000/callback"

​
Notification Settings

🚧 Notification features are currently under development. These variables are reserved for future use.
# Slack Integration (Coming Soon)
export SLACK_ENABLED=false
export SLACK_WEBHOOK_URL=https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX

# SMTP Configuration (Coming Soon)
export SMTP_ENABLED=false
export SMTP_PASSWORD=123456
export SMTP_USERNAME=abcdef

​
Keycloak Gateway Configuration

# Keycloak Gateway Settings
export KEYCLOAK_GATEWAY_URL=localhost
export KEYCLOAK_GATEWAY_PORT=8281
export KEYCLOAK_GATEWAY_SECRET=r4MBE75Axgsiu143HGvgQ1qlK6B9LCj5

​
Complete Environment Variables

Here’s the complete set of environment variables in a single block: 
# Java and Maven
export JAVA_HOME=$(/usr/libexec/java_home -v 21)
export PATH=$JAVA_HOME/bin:$PATH
export M2_HOME="/Applications/IntelliJ IDEA CE.app/Contents/plugins/maven/lib/maven3"
export PATH="$M2_HOME/bin:$PATH"

# Base directory for SSL keys
export KEY_BASE_DIR="/etc/keys"

# Eureka Discovery Server
export EUREKA_KEY_STORE="$KEY_BASE_DIR/eureka-keystore.jks"
export EUREKA_KEY_STORE_PASSWORD="123456"

# API Gateway
export GATEWAY_KEY_STORE="$KEY_BASE_DIR/gateway-keystore.jks"
export GATEWAY_KEY_STORE_PASSWORD="123456"
export GATEWAY_TRUST_STORE="$KEY_BASE_DIR/gateway-truststore.jks"
export GATEWAY_TRUST_STORE_PASSWORD="123456"

# Client Microservices
export CLIENT_KEY_STORE="$KEY_BASE_DIR/client-keystore.jks"
export CLIENT_KEY_STORE_PASSWORD="123456"
export CLIENT_TRUST_STORE="$KEY_BASE_DIR/client-truststore.jks"
export CLIENT_TRUST_STORE_PASSWORD="123456"

# OAuth2 Settings
export OAUTH2_REDIRECT_URI="http://localhost:3000/callback"

# Notification Settings (Coming Soon)
export SLACK_ENABLED=false
export SLACK_WEBHOOK_URL=https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX
export SMTP_ENABLED=false
export SMTP_PASSWORD=123456
export SMTP_USERNAME=abcdef

# Keycloak Gateway Settings
export KEYCLOAK_GATEWAY_URL=localhost
export KEYCLOAK_GATEWAY_PORT=8281
export KEYCLOAK_GATEWAY_SECRET=r4MBE75Axgsiu143HGvgQ1qlK6B9LCj5

​
Applying Changes

After setting the variables, apply the changes: 
source ~/.zshrc

​
Verification

Verify your configuration by checking the certificate paths: 
echo $EUREKA_KEY_STORE
echo $GATEWAY_KEY_STORE
echo $CLIENT_KEY_STORE
The output should show the full paths to your certificate files based on your KEY_BASE_DIR setting.

​
Important Notes

  • Ensure all certificate files exist in the specified locations before starting the services
  • Default password for all keystores is 123456
  • Notification services (Slack and SMTP) are disabled by default
  • Adjust the OAuth2 redirect URI according to your frontend application’s configuration
