Run an Asterisk on behalf of the same user

 sed -i 's/ASTARGS=""/ASTARGS="-U asterisk"/g'  /usr/sbin/safe_asterisk

Create an Asterisk user and change own

useradd -m asterisk &&
chown asterisk.asterisk /var/run/asterisk &&
chown -R asterisk.asterisk /etc/asterisk &&
chown -R asterisk.asterisk /var/{lib,log,spool}/asterisk &&
chown -R asterisk.asterisk /usr/lib/asterisk

Let's check Asterisk

/etc/init.d/asterisk start
Starting asterisk (via systemctl):                         [  OK  ]

ps aux | grep asterisk
root       872  0.0  0.0 115300   780 ?        S    12:12   0:00 /bin/sh /usr/sbin/safe_asterisk
asterisk   881  2.4  0.9 1314384 36532 ?       Sl   12:12   0:01 /usr/sbin/asterisk -f -U asterisk -vvvg -c

If the prompt is:

 Unable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?)

just restart the sever and:

 asterisk -vvvr

Configuring ODBC

   yum install -y mysql-connector-odbc unixODBC unixODBC-devel

*for reference, was established during the preparation of the system.

Create a required databases and grant privileges

asteriskcdrdb

 mysqladmin -p create asteriskcdrdb

 mysql -p -e "GRANT ALL PRIVILEGES ON asteriskcdrdb.* to CDR_DB_USER@localhost identified by 'CDR_DB_PASSWORD';"

 mysql -p -e "FLUSH PRIVILEGES;"

asteriskcdrdb.cdr schema

realtimedb

 mysqladmin -p create realtimedb

 mysql -p -e "GRANT ALL PRIVILEGES ON realtimedb.* to RT_DB_USER@localhost identified by 'RT_DB_PASSWORD';"

 mysql -p -e "FLUSH PRIVILEGES;"

realtimedb SQL schema

Where CDR_DB_USER, RT_DB_USER and CDR_DB_PASSWORD, RT_DB_PASSWORD It's YOUR data.

insert into the odbc.ini file (create, if it does not exist)

cat >> /etc/odbc.ini << EOF
[MySQL-asteriskcdrdb]

and

cat >> /etc/odbc.ini << EOF

Reference. What is the correct location of mysql.sock file on linux?

# mysql -e -p "show variables like 'socket';"
+---------------+---------------------------+
| Variable_name | VALUE                     |
+---------------+---------------------------+
| socket        | /var/lib/mysql/mysql.sock |

Asterisk Realtime Configuration

Enabled autoload modules

Hidden because of the length, please read. Important

Restart Asterisk

 asterisk -rx 'core restart now'

Create Asterisk res_odbc config

 touch /etc/asterisk/res_odbc.conf &&
 chown asterisk. /etc/asterisk/res_odbc.conf

cat >> /etc/asterisk/res_odbc.conf << EOF
[realtimedb]
