Installation: Create and configure the yml files

Notes

The YML files store the confidential information needed to connect the HydraDAM code to the other elements of the system, including Fedora, Solr, and Redis.

Steps

You may review the sample .yml files for MySQL, Fedora, Redis, and Solr in the/opt/$HYDRA_NAME/config directory. If you choose to edit them directly, use only the spacebar to create indentation as tabs are not allowed in YML syntax and will trigger a "found token that cannot start any token while scanning for the next token" error.

1. Create a production database.yml file that points to your MySQL database by entering the commands below.

   cat > /opt/$HYDRA_NAME/config/database.yml <<EOF
   production:  
     adapter: mysql2
     host: localhost
     database: hd_production
     username: hdProd
     password: hdProd
     pool: 5
     timeout: 5000
   EOF

2. Create a production fedora.yml file that points to your Fedora by entering the commands below.

   cat > /opt/$HYDRA_NAME/config/fedora.yml <<EOF
   production:
     user: fedoraAdmin
     password: fedoraAdmin
     url: http://127.0.0.1:8080/fedora
   EOF

3. Create a production redis.yml file that points to your Redis server by entering the commands below.

   cat > /opt/$HYDRA_NAME/config/redis.yml <<EOF
   production:
     host: localhost
     port: 6379
   EOF

4. Create a production solr.yml file that points to your Solr by entering the commands below.

   cat > /opt/$HYDRA_NAME/config/solr.yml << EOF
   production:
     url: http://127.0.0.1:8080/hydradam/
   EOF

Verification Steps

1. Enter the command ls -la /opt/$HYDRA_NAME/config in the terminal window. This should return (among other files) database.yml, fedora.yml, redis.yml, and solr.yml. If you want to view the contents of each file, enter the command less filename.yml. To exit and return to the terminal window, type 'q'.
