ejabberd 16.04 archiving messages in mysql database

These are some of the key points of my ejabberd.yml

auth_method: odbc

## MySQL server:

odbc_type: mysql
odbc_server: "localhost"
odbc_database: "chat"
odbc_username: "admin"
odbc_password: "admin"

## If you want to specify the port:
odbc_port: 3306


modules
...
mod_mam:
db_type: odbc


Full ejabberd.yml

###
###' ejabberd configuration file
###
###

### The parameters used in this configuration file are explained in more detail
### in the ejabberd Installation and Operation Guide.
### Please consult the Guide in case of doubts, it is included with
### your copy of ejabberd, and is also available online at
### http://www.process-one.net/en/ejabberd/docs/

### The configuration file is written in YAML.
### Refer to http://en.wikipedia.org/wiki/YAML for the brief description.
### However, ejabberd treats different literals as different types:
###
### - unquoted or single-quoted strings. They are called "atoms".
### Example: dog, 'Jupiter', '3.14159', YELLOW
###
### - numeric literals. Example: 3, -45.0, .0
###
### - quoted or folded strings.
### Examples of quoted string: "Lizzard", "orange".
### Example of folded string:
### > Art thou not Romeo,
### and a Montague?

###. =======
###' LOGGING

##
## loglevel: Verbosity of log files generated by ejabberd.
## 0: No ejabberd log at all (not recommended)
## 1: Critical
## 2: Error
## 3: Warning
## 4: Info
## 5: Debug
##
loglevel: 4

##
## rotation: Describe how to rotate logs. Either size and/or date can trigger
## log rotation. Setting count to N keeps N rotated logs. Setting count to 0
## does not disable rotation, it instead rotates the file and keeps no previous
## versions around. Setting size to X rotate log when it reaches X bytes.
## To disable rotation set the size to 0 and the date to ""
## Date syntax is taken from the syntax newsyslog uses in newsyslog.conf.
## Some examples:
## $D0 rotate every night at midnight
## $D23 rotate every day at 23:00 hr
## $W0D23 rotate every week on Sunday at 23:00 hr
## $W5D16 rotate every week on Friday at 16:00 hr
## $M1D0 rotate on the first day of every month at midnight
## $M5D6 rotate on every 5th day of the month at 6:00 hr
##
log_rotate_size: 10485760
log_rotate_date: ""
log_rotate_count: 1

##
## overload protection: If you want to limit the number of messages per second
## allowed from error_logger, which is a good idea if you want to avoid a flood
## of messages when system is overloaded, you can set a limit.
## 100 is ejabberd's default.
log_rate_limit: 100

##
## watchdog_admins: Only useful for developers: if an ejabberd process
## consumes a lot of memory, send live notifications to these XMPP
## accounts.
##
## watchdog_admins:
## - "admin@jabber.local"

###. ===============
###' NODE PARAMETERS

##
## net_ticktime: Specifies net_kernel tick time in seconds. This options must have

## - "example.org"
##
hosts:
- "jabber.local"

##
## route_subdomains: Delegate subdomains to other XMPP servers.

I've executed mysql.sql script on phpmyadmin and the database is correctly setted up.

The problem is that I'm not able to link ejabberd with mysql because when I register a user with ejabberd web admin it doesn't store it in sql database.
Since I can't store the user I'm not able to check for the messaging storage neither.

Am I missing something?

Regards!

EDIT:

user on .yml

admin:
user:
- "admin": "jabber.local"
- "admin": "localhost"

Answer

You have an issue with your database configuration. ejabberd cannot connect to it, as stated in error message:

Failed connecting to "localhost":3306 : {error,econnrefused}

You are saying that it stores users in SQL db, but you are likely mistaken as ejabberd cannot connect to the database.

I think it should be actually storing data in Mnesia. This is confirmed by your config (auth_method: internal)
