Install requirements

• Install Python 3 (version >= 3.6.9) and python3-pip. For example, sudo apt install python3
• Install PostgreSQL (any version) and postgresql-server-dev-all. For example, sudo apt install postgresql postgresql-server-dev-all
• Start PosgreSQL, create a new user login, and configure database information in server_config.yaml. Example commands are:
  • sudo su
  • su - postgres
  • psql
  • create user optimizer with password '123456';
  • create database optimizerdb owner optimizer;
  • \q then exit twice
• Clone/Download this repository: git clone https://github.com/minhhpham/MASS-webserver
• cd MASS-webserver
• pip3 install -r requirements.txt
• Run server in development mode: python3 MASS-webserver.py
• If seeing a bug that says Peer authentication failed for user "optimizer" , do the following:
  • Navigate to file Postgres' config file named pg_hba.conf, usually located at /etc/postgresql/10/main/pg_hba.conf
  • Open file with root privilege: sudo nano /etc/postgresql/10/main/pg_hba.conf
  • Navigate to end of file, there will be a table. Change the entire last column to 'md5'
  • Save file and restart Postgres service with sudo systemctl restart postgresql

Setup the Optimizer

• Clone this repository in the parent directory of MASS-webserver and follow the instruction in the README.md file. For examlpe, you can run:
  • cd ..
  • git clone https://github.com/ZulqarnainHaider/MASS-Optimizer
  • cd MASS-Optimizer and follow the instructions in README.
• Add julia to PATH:
  • sudo nano ~/.bashrc
  • Add this line to the file: export PATH=<path_to_julia>${PATH:+:${PATH}}
• After setting up MASS-Optimizer, the directory tree should look like this:
