INSTALL GUIDE

(for dummmies...I mean novice web developers)

  1. Install dependencies
Install PostgreSQL
sudo apt-get install postgresql postgresql-contrib
Install PHP and NGINX
sudo apt-get install php php-fpm php-bcmath php-sqlite php-pgsql php-mcrypt php-curl php-mbstring
Install npm and gulp (for building frontend)
sudo apt-get install npm
sudo npm install ---global gulp-cli
Install rabbitmq for asynchronous tasks (schema updating etc.)
sudo apt-get install rabbitmq-server
  1. Enable Tracy debugger

To really see what is going wrong, it is VERY helpful to setup debugging environment Tracy. It should suffice to:

cp app/bootstrap.php.debug app/bootstrap.php:

Then you should get extremely nice debug info right in the browser! To see available commands in the app:

php www/index.php list
  1. Configure Postgre

According to a guide for Ubuntu

sudo -u postgres createuser --superuser $USER
sudo -u postgres psql
postgres=# \password $USER
Create the database (name must match config.local.neon)
createdb khanovaskola

(if you create DB under different psql user, you need to execute something like this)

GRANT ALL PRIVILEGES ON DATABASE khanovaskola to khanovaskola;
  1. Configure app/config/config.local.neon Tip: Get the template from:
cp app/config/stages/dev.neon app/config/config.local.neon

Note: the database parameters must match what you did in step 3.

  1. Creating initial database inside PSQL
php www/index.php migrations:migrate --init
php www/index.php migrations:migrate

LOKI: After this step you can import data from KA. See production/crontab to see how.

  • Alternatively, import previous backup
php index.php  backup:list
php index.php  backup:restore TIMESTAMP  (first number form previous command)
  • Clear the data in the database
php www/index.php data:drop

To understand the database schema, look into SQL.md

  1. Setting up NGINX

you may need to execute this for git to ignore these changes:

git config core.fileMode false

  • sudo nginx -s stop

  • Setup the web at localhost via an nginx conf file. For development, you can use (production/nginx-dev.conf) [production/nginx-dev.conf]. For production with HTTPS, look at (production/nginx.conf)[production/nginx.conf]

cp production/nginx-dev.conf /etc/nginx/sites-available/ka-dev.conf
ln -s /etc/nginx/sites-available/ka-dev.conf /etc/nginx/sites-enabled/ka-dev.conf

  • Make sure that user www-data is in the group that you previously used for the repo

  • Modify /etc/hosts , include e.g.

127.0.0.1 ks.cz
  • sudo nginx
  1. TODO: How to setup elasticsearch server
  1. Setting up workers via cron jobs for async tasks (this is supremely important for production servers)
sudo cp production/crontab /etc/cron.d/KA
  1. Granting admin privileges to a user UPDATE USERS SET privileges = '["all"]' WHERE id = '1';

DEBUGGING

(The following are messages from Tracy and corresponding corrective action)

Problem: ERROR in Kdyby/Facebook: Use of undefined constant URLOPT_CONNECTTIMEOUT – assumed ‚CURLOPT_CONNECTTIMEOUT‘

Solution:

sudo apt-get install php-curl

Problem: Missing parameter ‘locale’

Solution: add parameter locale: “en” in app/config/config.local.neon (watch out, must be escaped with a TAB)

Problem: Call to undefined function App\Models\Services\mcrypt_get_iv_size()

Solution: sudo apt-get install php5-mcrypt
