Configure Ejabberd chat server to use PostgreSQL

Date: 2016-04-04 19:58:00

In order to make data persistent with in any application, we can link it to a PostgreSQL relational database.

To change the default to use a postgres database we first need to create a new postgresql database on the server

huazhang@zhoutekiMacBook-Air:~/ejabberd-15.09/bin$ psql
psql (9.4.4)
huazhang=# run ./createdb ejabberd
```

2. Create the tables using the supplied script

huazhang-# ./psql ejabberd < ~/ejabberd-15.09/lib/ejabberd-15.09/priv/sql/pg.sql

3. Add a user for the database

~/ejabberd-15.09/bin$ createuser -P -s -e admin

Enter password for new role: root123

Enter it again: root123

CREATE ROLE testadmin PASSWORD ‘md55ebf4663bc3108d036c91bc4bbcfd599’ SUPERUSER CREATEDB CREATEROLE INHERIT LOGIN;

4. Configure ODBC options in ejabberd.cfg:

Scroll down to the section headed Database setup.

edit the following, remove the %% commenting

PostgreSQL server:

odbc_type: pgsql

odbc_server: “localhost”

odbc_database: “ejabberd”

odbc_username: “admin”

odbc_password: “root123”

5. Add _odbc to modules you wish to use the odbc database, and store messages into archive table

e.g. mod_offline_odbc instead of mod_offline.

full list in ejabberd user guide

Modules enabled in all ejabberd virtual hosts.

modules:

#By default mod_mam does not store messages. If you like to store messages, simply add this mod_mam option:

mod_mam:

default: always

db_type: odbc

“`

Under authentication comment out internal authentication:

“`

auth_method: internal

Then un comment auth_method: odbc

“`

Register a new user and appear online using PSI client or similar application

Add a user to allowed admin access control list in ejabberd.cfg

{acl, admin, {user, "username", "server"}}.

Confirm registered user and status in web admin:

http://serverIP:5280/admin/

Connect to database using PgAdmin to view tables with data and confirm ejabberd is now using PostgreSQL
