MySQL is a relational database that can be used to store user generated content (UGC).

These instructions describe how to connect to the MySQL server and establish the UGC database.

Requirements requirements

Latest Communities feature pack
JDBC driver for MySQL
A relational database:
- MySQL server Community Server version 5.6 or later
  - May run on same host as AEM or run remotely
- MySQL workbench

Installing MySQL installing-mysql

MySQL should be downloaded and installed following the instructions for the target OS.

Lower case table names lower-case-table-names

As SQL is case insensitive, for case sensitive operating systems, it is necessary to include a setting to lower case all table names.

For example, to specify all lower case table names on a Linux OS:

Edit file /etc/my.cnf
In the [mysqld] section, add the following line:

lower_case_table_names = 1

UTF8 character set utf-character-set

To provide better multilingual support, it is necessary to use the UTF8 character set.

Change MySQL to have UTF8 as its character set:

mysql > SET NAMES ‘utf8’;

Change the MySQL database to default to UTF8:

Edit file /etc/my.cnf
In the [client] section, add the following line:

default-character-set=utf8
In the [mysqld] section, add the following line:

character-set-server=utf8

Installing MySQL Workbench installing-mysql-workbench

MySQL Workbench provides an UI for executing SQL scripts which install the schema and initial data.

MySQL Workbench should be downloaded and installed following the instructions for the target OS.

Communities Connection communities-connection

When the MySQL Workbench is first launched, unless already in use for other purposes, it will not yet show any connections:

mysqlconnection

New Connection Settings new-connection-settings

Select the + icon to the right of MySQL Connections.
In the dialog Setup New Connection, enter values appropriate for your platform

For demonstration purposes, with the author AEM instance and MySQL on the same server:
- Connection Name: Communities
- Connection Method: Standard (TCP/IP)
- Hostname: 127.0.0.1
- Username: root
- Password: no password by default
- Default Schema: leave blank
Select Test Connection to verify the connection to the running MySQL service

Notes:

The default port is 3306
The Connection Name chosen is entered as the datasource name in JDBC OSGi configuration

New Communities Connection new-communities-connection

community-connection

Database Setup database-setup

Open the Communities connection to install the database.

install-database

Obtain the SQL Script obtain-the-sql-script

The SQL script is obtained from the AEM repository:

Browse to CRXDE Lite
- For example, http://localhost:4502/crx/de
Select the /libs/social/config/datastore/dsrp/schema folder
Download init-schema.sql

One method for downloading the schema is to:

Select the jcr:content node for the sql file
Notice the value for the jcr:data property is a view link
Select the view link to save the data to a local file

Create the DSRP Database create-the-dsrp-database

Follow the steps below to install the database. The default name of the database is communities.

If the database name is changed in the script, be sure to also change it in the JDBC config.

Step 1: open SQL file step-open-sql-file

In the MySQL Workbench

From the File pulldown menu, select the Open SQL Script option
Select the downloaded init_schema.sql script

select-sql-script

Step 2: execute SQL Script step-execute-sql-script

In the Workbench window for the file opened in Step 1, select the lightening (flash) icon to execute the script.

In the following image, the init_schema.sql file is ready to be executed:

execute-sql-script

Refresh refresh

Once the script is executed, it is necessary to refresh the SCHEMAS section of the Navigator to see the new database. Use the refresh icon to the right of ‘SCHEMAS’:

refresh-schema

Configure JDBC Connection configure-jdbc-connection

The OSGi configuration for Day Commons JDBC Connections Pool configures the MySQL JDBC Driver.

All publish and author AEM instances should point to the same MySQL server.

When MySQL runs on a server different from AEM, the server hostname must be specified in place of ‘localhost’ in the JDBC connector.

On each author and publish AEM instance.
Signed in with administrator privileges.
Access the web console.
- For example, http://localhost:4502/system/console/configMgr
Locate the Day Commons JDBC Connections Pool
Select the + icon to create a connection configuration.
Enter the following values:
- JDBC driver class: com.mysql.jdbc.Driver
- JDBC connection URI: jdbc:mysql://localhost:3306/communities?characterEncoding=UTF-8
  
  Specify server in place of localhost if MySQL server is not the same as ‘this’ AEM server communities is the default database (schema) name.
- Username: root
  
  Or enter the configured Username for the MySQL server, if not ‘root’.
- Password:
  
  Clear this field if no password set for MySQL,
  
  else enter the configured password for the MySQL Username.
- Datasource name: name entered for the MySQL connection, for example, ‘communities’.
Select Save
