NyaaV2

Setup:

• Create your virtualenv, for example with pyvenv venv
• Enter your virtualenv with source venv/bin/activate
• Install dependencies with pip install -r requirements.txt
• Run python db_create.py to create the database
• Start the dev server with python run.py

Updated Setup (python 3.6.1):

• Install dependencies https://github.com/pyenv/pyenv/wiki/Common-build-problems
• Install pyenv https://github.com/pyenv/pyenv/blob/master/README.md#installation
• Install pyenv-virtualenv https://github.com/pyenv/pyenv-virtualenv/blob/master/README.md
• pyenv install 3.6.1
• pyenv virtualenv 3.6.1 nyaa
• pyenv activate nyaa
• Install dependencies with pip install -r requirements.txt
• Copy config.example.py into config.py
• Change TALBE_PREFIX to nyaa_ or sukebei_ depending on the site

Setting up MySQL/MariaDB database for advanced functionality

• Enable USE_MYSQL flag in config.py
• Install latest mariadb by following instructions here https://downloads.mariadb.org/mariadb/repositories/
  • Tested versions: mysql Ver 15.1 Distrib 10.0.30-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
• Run the following commands logged in as your root db user:
  • CREATE USER 'test'@'localhost' IDENTIFIED BY 'test123';
  • GRANT ALL PRIVILEGES ON * . * TO 'test'@'localhost';
  • FLUSH PRIVILEGES;
  • CREATE DATABASE nyaav2 DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;
• To setup and import nyaa_maria_vx.sql:
  • mysql -u <user> -p nyaav2
  • DROP DATABASE nyaav2;
  • CREATE DATABASE nyaav2 DEFAULT CHARACTER SET utf8 COLLATE utf8_bin;
  • SOURCE ~/path/to/database/nyaa_maria_vx.sql

Finishing up

• Run python db_create.py to create the database
• Load the .sql file
  • mysql -u user -p nyaav2
  • SOURCE cocks.sql
  • Remember to change the default user password to an empty string to disable logging in
• Start the dev server with python run.py
• Deactivate source deactivate

Enabling ElasticSearch

Basics

• Install jdk sudo apt-get install openjdk-8-jdk
• Install elasticsearch https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html
• sudo systemctl enable elasticsearch.service
• sudo systemctl start elasticsearch.service
• Run curl -XGET 'localhost:9200' and make sure ES is running
• Optional: install Kabana as a search frontend for ES

Enable MySQL Binlogging

• Add the [mariadb] bin-log section to my.cnf and reload mysql server
• Connect to mysql
• SHOW VARIABLES LIKE 'binlog_format';
  • Make sure it shows ROW
• Connect to root user
• GRANT REPLICATION SLAVE ON *.* TO 'test'@'localhost'; where test is the user you will be running sync_es.py with

Setting up ES

• Run ./create_es.sh and this creates two indicies: nyaa and sukebei
• The output should show akncolwedged: true twice
• The safest bet is to disable the webapp here to ensure there's no database writes
• Run python import_to_es.py with SITE_FLAVOR set to nyaa
• Run python import_to_es.py with SITE_FLAVOR set to sukebei
• These will take some time to run as it's indexing

Setting up sync_es.py

• Sync_es.py keeps the ElasticSearch index updated by reading the BinLog
• Configure the MySQL options with the user where you granted the REPLICATION permissions
• Connect to MySQL, run SHOW MASTER STATUS;.
• Copy the output to /var/lib/sync_es_position.json with the contents {"log_file": "FILE", "log_pos": POSITION} and replace FILENAME with File (something like master1-bin.000002) in the SQL output and POSITION (something like 892528513) with Position
• Set up sync_es.py as a service and run it, preferably as the system/root
• Make sure sync_es.py runs within venv with the right dependencies

Good to go!

• After that, enable the USE_ELASTIC_SEARCH flag and restart the webapp and you're good to go

Code Quality:

• Remember to follow PEP8 style guidelines and run ./lint.sh before committing.
