    • Windows

      docker-compose-down.bat
      

      Caution: As per the default configuration in the docker-compose-mentoring.yml file, using the down command will lead to data loss since the database container does not persist data. To persist data across down commands and subsequent container removals, refer to the "Persistence of Database Data in Docker Containers" section of this documentation.

Enable Citus Extension

MentorEd relies on PostgreSQL as its core database system. To boost performance and scalability, users can opt to enable the Citus extension. This transforms PostgreSQL into a distributed database, spreading data across multiple nodes to handle large datasets more efficiently as demand grows.

For more information, refer Citus Data.

To enable the Citus extension for mentoring and user services, follow these steps.

1. Create a sub-directory named mentoring and download distributionColumns.sql into it.

   mkdir mentoring && curl -o ./mentoring/distributionColumns.sql -JL https://github.com/ELEVATE-Project/mentoring/raw/master/documentation/2.6.1/distribution-columns/mentoring/distributionColumns.sql
   

2. Create a sub-directory named user and download distributionColumns.sql into it.

   mkdir user && curl -o ./user/distributionColumns.sql -JL https://github.com/ELEVATE-Project/mentoring/raw/master/documentation/2.6.1/distribution-columns/user/distributionColumns.sql
   

3. Set up the citus_setup file by following the steps given below.

   • Ubuntu/Linux/Mac

     1. Download the citus_setup.sh file.

        curl -OJL https://github.com/ELEVATE-Project/mentoring/raw/master/documentation/2.6.1/dockerized/scripts/mac-linux/citus_setup.sh
        

     2. Make the setup file executable by running the following command.

        chmod +x citus_setup.sh
        

     3. Enable Citus and set distribution columns for mentoring database by running the citus_setup.shwith the following arguments.

        ./citus_setup.sh mentoring postgres://postgres:postgres@citus_master:5432/mentoring
        

     4. Enable Citus and set distribution columns for user database by running the citus_setup.shwith the following arguments.

        ./citus_setup.sh user postgres://postgres:postgres@citus_master:5432/user
        

   • Windows

     1. Download the citus_setup.bat file.

         curl -OJL https://github.com/ELEVATE-Project/mentoring/raw/master/documentation/2.6.1/dockerized/scripts/windows/citus_setup.bat
        

     2. Enable Citus and set distribution columns for mentoring database by running the citus_setup.batwith the following arguments.

        citus_setup.bat mentoring postgres://postgres:postgres@citus_master:5432/mentoring
        

     3. Enable Citus and set distribution columns for user database by running the citus_setup.batwith the following arguments.

        citus_setup.bat user postgres://postgres:postgres@citus_master:5432/user
        

        Note: Since the citus_setup.bat file requires arguments, it must be run from a terminal.

Persistence Of Database Data In Docker Container

To ensure the persistence of database data when running docker compose down, it is necessary to modify the docker-compose-mentoring.yml file according to the steps given below:

1. Modification Of The docker-compose-mentoring.yml File:

   Begin by opening the docker-compose-mentoring.yml file. Locate the section pertaining to the Citus container and proceed to uncomment the volume specification. This action is demonstrated in the snippet provided below:

   citus:
       image: citusdata/citus:11.2.0
       container_name: 'citus_master'
       ports:
           - 5432:5432
       volumes:
           - citus-data:/var/lib/postgresql/data

2. Uncommenting Volume Names Under The Volumes Section:

   Next, navigate to the volumes section of the file and proceed to uncomment the volume names as illustrated in the subsequent snippet:

   networks:
       elevate_net:
           external: false
   
   volumes:
       citus-data:

By implementing these adjustments, the configuration ensures that when the docker-compose down command is executed, the database data is securely stored within the specified volumes. Consequently, this data will be retained and remain accessible, even after the containers are terminated and subsequently reinstated using the docker-compose up command.

Sample User Accounts Generation

During the initial setup of MentorEd services with the default configuration, you may encounter issues creating new accounts through the regular SignUp flow on the MentorEd portal. This typically occurs because the default SignUp process includes OTP verification to prevent abuse. Until the notification service is configured correctly to send actual emails, you will not be able to create new accounts.

In such cases, you can generate sample user accounts using the steps below. This allows you to explore the MentorEd services and portal immediately after setup.

Warning: Use this generator only immediately after the initial system setup and before any normal user accounts are created through the portal. It should not be used under any circumstances thereafter.

1. Download The sampleData.sql Files:

   • Ubuntu/Linux/Mac

     mkdir -p sample-data/mentoring sample-data/user && \
     curl -L https://raw.githubusercontent.com/ELEVATE-Project/mentoring/master/documentation/2.6.1/sample-data/mac-linux/mentoring/sampleData.sql -o sample-data/mentoring/sampleData.sql && \
     curl -L https://raw.githubusercontent.com/ELEVATE-Project/mentoring/master/documentation/2.6.1/sample-data/mac-linux/user/sampleData.sql -o sample-data/user/sampleData.sql
     

   • Windows

     mkdir sample-data\mentoring 2>nul & mkdir sample-data\user 2>nul & ^
     curl -L "https://raw.githubusercontent.com/ELEVATE-Project/mentoring/master/documentation/2.6.1/sample-data/windows/mentoring/sampleData.sql" -o sample-data\mentoring\sampleData.sql & ^
     curl -L "https://raw.githubusercontent.com/ELEVATE-Project/mentoring/master/documentation/2.6.1/sample-data/windows/user/sampleData.sql" -o sample-data\user\sampleData.sql
     

2. Download The insert_sample_data Script File:

   • Ubuntu/Linux/Mac

     curl -L -o insert_sample_data.sh https://raw.githubusercontent.com/ELEVATE-Project/mentoring/master/documentation/2.6.1/dockerized/scripts/mac-linux/insert_sample_data.sh && chmod +x insert_sample_data.sh
     

   • Windows

     curl -L -o insert_sample_data.bat https://raw.githubusercontent.com/ELEVATE-Project/mentoring/master/documentation/2.6.1/dockerized/scripts/windows/insert_sample_data.bat
     

3. Run The insert_sample_data Script File:

   • Ubuntu/Linux/Mac

     ./insert_sample_data.sh user postgres://postgres:postgres@citus_master:5432/user && \
     ./insert_sample_data.sh mentoring postgres://postgres:postgres@citus_master:5432/mentoring
     

   • Windows

     insert_sample_data.bat user postgres://postgres:postgres@citus_master:5432/user & ^
     insert_sample_data.bat mentoring postgres://postgres:postgres@citus_master:5432/mentoring
     

   After successfully running the script mentioned above, the following user accounts will be created and available for login:

   Email ID	Password	Role
   [email protected]	Password1@	Mentee
   [email protected]	Password1@	Mentor
   [email protected]	Password1@	Organization Admin

Natively Installed Services & Dependencies

PM2 Managed Services & Natively Installed Dependencies

Expectation: Upon following the prescribed steps, you will achieve a fully operational MentorEd application setup. Both the portal and backend services are managed using PM2, with all dependencies installed natively on the host system.

Prerequisites

Before setting up the following MentorEd application, dependencies given below should be installed and verified to be running. Refer to the steps given below to install them and verify.

• Ubuntu/Linux

  1. Download dependency management scripts:

     curl -OJL https://github.com/ELEVATE-Project/mentoring/raw/master/documentation/2.6.1/native/scripts/linux/check-dependencies.sh && \
     curl -OJL https://github.com/ELEVATE-Project/mentoring/raw/master/documentation/2.6.1/native/scripts/linux/install-dependencies.sh && \
     curl -OJL https://github.com/ELEVATE-Project/mentoring/raw/master/documentation/2.6.1/native/scripts/linux/uninstall-dependencies.sh && \
     chmod +x check-dependencies.sh && \
     chmod +x install-dependencies.sh && \
     chmod +x uninstall-dependencies.sh
     

  2. Verify installed dependencies by running check-dependencies.sh:

     ./check-dependencies.sh
     

     Note: Keep note of any missing dependencies.

  3. Install dependencies by running install-dependencies.sh:

     ./install-dependencies.sh
     

     Note: Install all missing dependencies and use check-dependencies script to ensure everything is installed and running.

  4. Uninstall dependencies by running uninstall-dependencies.sh:

     ./uninstall-dependencies.sh
     

     Warning: Due to the destructive nature of the script (without further warnings), it should only be used during the initial setup of the dependencies. For example, Uninstalling PostgreSQL/Citus using script will lead to data loss. USE EXTREME CAUTION.

     Warning: This script should only be used to uninstall dependencies that were installed via installation script in step 3. If same dependencies were installed using other methods, refrain from using this script. This script is provided in-order to reverse installation in-case issues arise from a bad install.

• MacOS

  1. Install Node.js 20:

     brew install node@20
     

     brew link --overwrite node@20
     

  2. Install Kafka:

     brew install kafka
     

  3. Install PostgreSQL 16:

     brew install postgresql@16
     

  4. Install PM2:

     sudo npm install pm2@latest -g
     

  5. Install Redis:

     brew install redis
     

  6. Download check-dependencies.sh file:

     curl -OJL https://github.com/ELEVATE-Project/mentoring/raw/master/documentation/2.6.1/native/scripts/macos/check-dependencies.sh && \
     chmod +x check-dependencies.sh
     

  7. Verify installed dependencies by running check-dependencies.sh:

     ./check-dependencies.sh
     

• Windows

  1. Install Node.js 20:

     Download and install Node.js v20 for Windows platform (x64) from official Node.js download page.

  2. Install Kafka 3.5.0:

     1. Adapt the instructions given in the following "Apache Kafka on Windows" documentation to install Kafka version 3.5.0.

        Note: As per the instructions, Kafka server and Zookeeper has to be kept active on different WSL terminals for the entire lifetime of MentorEd services.

        Note: Multiple WSL terminals can be opened by launching Ubuntu from start menu.

     2. Open a new WSL terminal and execute the following command to get the IP of the WSL instance.

        ip addr show eth0
        

        Sample Output:

        2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1492 qdisc mq state UP group default qlen 1000
        link/ether 11:56:54:f0:as:vf brd ff:ff:ff:ff:ff:ff
        inet 172.12.46.150/20 brd 172.24.79.255 scope global eth0
            valid_lft forever preferred_lft forever
        inet6 fe80::215:5dff:fee7:dc52/64 scope link
            valid_lft forever preferred_lft forever
        

        Keep note of the IP address shown alongside inet. In the above case, 172.12.46.150 is IP address of the WSL instance.

     3. In the same WSL terminal, navigate to config directory of Kafka from step 1 and make the following changes to server.properties file.

        • Uncomment listeners=PLAINTEXT://:9092 line and change it to listeners=PLAINTEXT://0.0.0.0:9092 to allow connections from any IP.

        • Uncomment advertised.listeners line and set it to advertised.listeners=PLAINTEXT://172.12.46.150:9092. Replace 172.12.46.150 with the actual IP address of your WSL instance.

     4. Restart the Zookeeper and Kafka Server from their own WSL terminals from step 1.

  3. Install Redis:

     1. Follow the instructions given in the official Redis Documentation to install Redis using WSL.

     2. Using the WSL terminal, open the Redis configuration file in a text editor, such as nano:

        sudo nano /etc/redis/redis.conf
        

     3. Find the line containing bind 127.0.0.1 ::1 and change it to bind 0.0.0.0 ::.. This change allows Redis to accept connections from any IP address. Then save and exit the file.

     4. Restart Redis to apply the changes:

        sudo service redis-server restart
        

  4. Install PM2:

     npm install pm2@latest -g
     

  5. Install PostgreSQL 16:

     1. Download and install PostgreSQL 16 from EnterpriseDB PostgreSQL download page.

        Note: Set username and password for the default database to be 'postgres' during installation.

     2. Once installed, Add C:\Program Files\PostgreSQL\16\bin to windows environment variables. Refer here or here for more information regarding how to set it.

   Note: Modify the environment files as necessary for your deployment using any text editor, ensuring that the values are appropriate for your environment. The default values provided in the current files are functional and serve as a good starting point. Refer to the sample env files provided at the Mentoring, User, Notification, Scheduler, and Interface repositories for reference.

   Caution: While the default values in the downloaded environment files enable the MentorEd Application to operate, certain features may not function correctly or could be impaired unless the adopter-specific environment variables are properly configured.

   For detailed instructions on adjusting these values, please consult the MentorEd Environment Variable Modification Guide.

   Important: As mentioned in the above linked document, the User SignUp functionality may be compromised if key environment variables are not set correctly during deployment. If you opt to skip this setup, consider using the sample user account generator detailed in the Sample User Accounts Generation section of this document.

Sample User Accounts Generation

During the initial setup of MentorEd services with the default configuration, you may encounter issues creating new accounts through the regular SignUp flow on the MentorEd portal. This typically occurs because the default SignUp process includes OTP verification to prevent abuse. Until the notification service is configured correctly to send actual emails, you will not be able to create new accounts.

In such cases, you can generate sample user accounts using the steps below. This allows you to explore the MentorEd services and portal immediately after setup.

Warning: Use this generator only immediately after the initial system setup and before any normal user accounts are created through the portal. It should not be used under any circumstances thereafter.

• Ubuntu/Linux

  curl -o insert_sample_data.sh https://raw.githubusercontent.com/ELEVATE-Project/mentoring/master/documentation/2.6.1/native/scripts/linux/insert_sample_data.sh && \
  chmod +x insert_sample_data.sh && \
  ./insert_sample_data.sh
  

• MacOS

  curl -o insert_sample_data.sh https://raw.githubusercontent.com/ELEVATE-Project/mentoring/master/documentation/2.6.1/native/scripts/macos/insert_sample_data.sh && \
  chmod +x insert_sample_data.sh && \
  ./insert_sample_data.sh
  

• Windows

  curl -o insert_sample_data.bat https://raw.githubusercontent.com/ELEVATE-Project/mentoring/master/documentation/2.6.1/native/scripts/windows/insert_sample_data.bat && ^
  insert_sample_data.bat
  

After successfully running the script mentioned above, the following user accounts will be created and available for login:

Email ID	Password	Role
[email protected]	Password1@	Mentee
[email protected]	Password1@	Mentor
[email protected]	Password1@	Organization Admin
