Install

DAHDI

Only required if using a physical server and installing telecom hardware.  At this time, versions newer than 2.10.2 (2.11.0 and 2.11.1) do not install correctly.

cd /usr/src
wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-2.10.2+2.10.2.tar.gz
tar zxvf dahdi-linux-complete-2.10*
cd /usr/src/dahdi-linux-complete-2.10*/
make all && make install && make config
systemctl restart dahdi

If make all fails try reboot and run yum install kernel-devel

Asterisk

If upgrading an existing install with older asterisk it is best to run  rm -rf /usr/lib64/asterisk/modules first.

cd /usr/src
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-16-current.tar.gz
tar zxvf asterisk-16-current.tar.gz
cd /usr/src/asterisk-16*/
make distclean

Install release specific dependencies

cd /usr/src/asterisk-16*/
./contrib/scripts/install_prereq install

Configure

cd /usr/src/asterisk-16*/
./configure --libdir=/usr/lib64 --with-jansson-bundled

To view results type nano -v config.log.

Set compile options

cd /usr/src/asterisk-16*/
make menuselect

# Go to Applications and make sure app_macro is checked.
# To add/change compile options afterwards just run make menuselect and make && make install again.

Create Asterisk User, compile, install and set preliminary ownership.

adduser asterisk -s /bin/bash -c "Asterisk User"
make && make install && chown -R asterisk. /var/lib/asterisk

Freepbx

systemctl restart mariadb

cd /usr/src
git clone -b release/16.0 --single-branch https://github.com/freepbx/framework.git freepbx
touch /etc/asterisk/modules.conf
cd /usr/src/freepbx
./start_asterisk start

./install -n

Module install

fwconsole ma downloadinstall framework core voicemail sipsettings infoservices \
featurecodeadmin logfiles callrecording cdr dashboard music soundlang recordings conferences pm2

fwconsole chown
fwconsole reload

Additional modules can be installed via GUI > Admin > Module Admin.

Optionally, install all modules (not recommended).  You may need to run the following commands twice.

fwconsole ma installall
fwconsole chown
fwconsole reload

Configure Freepbx to start on boot

cat >> /etc/systemd/system/freepbx.service << EOF
[Unit]
Description=Freepbx
After=mariadb.service
 
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/sbin/fwconsole start -q
ExecStop=/usr/sbin/fwconsole stop -q
 
[Install]
WantedBy=multi-user.target

EOF
systemctl enable freepbx

Post-install tasks

Lock down the database server.

mysql_secure_installation

Answer Y to everything.

Change apache web server settings.

sed -i 's/\(^upload_max_filesize = \).*/\120M/' /etc/php.ini
sed -i 's/^\(User\|Group\).*/\1 asterisk/' /etc/httpd/conf/httpd.conf
sed -i ':a;N;$!ba;s/AllowOverride None/AllowOverride All/2' /etc/httpd/conf/httpd.conf

Set required services are set to start on boot.

systemctl enable mariadb
systemctl enable httpd
systemctl enable postfix

Finally, reboot for all changes to take effect

reboot

Optional

Log File Rotation

If this is not done the log files will keep growing indefinitely.

nano /etc/logrotate.d/asterisk
/var/spool/mail/asterisk
/var/log/asterisk/full
/var/log/asterisk/dtmf
/var/log/asterisk/fail2ban {
        size 50M
        dateformat -%Y%m%d-%H
        missingok
        rotate 4
        #compress
        notifempty
        sharedscripts
        create 0640 asterisk asterisk
        postrotate
        /usr/sbin/asterisk -rx 'logger reload' > /dev/null 2> /dev/null || true
        endscript
        su root root
}

Set daily log rotate script to run hourly.  Based on above settings they will rotate if larger than 50 MB.  The rotated file will be datestamped and include the hour.  The hourly part prevents duplicate file errors from occurring when multiple rotations are attempted on the same day.

cp /etc/cron.daily/logrotate /etc/cron.hourly

Firewall

systemctl enable firewalld
systemctl restart firewalld
firewall-cmd --permanent --zone=public --add-service={http,https}
firewall-cmd --permanent --zone=public --add-port=5060-5061/tcp
firewall-cmd --permanent --zone=public --add-port=5060-5061/udp
firewall-cmd --permanent --zone=public --add-port=10000-20000/udp
firewall-cmd --reload

TFTP

If you plan to use hardware SIP phones you will probably want to set up TFTP.

yum -y install tftp-server
nano /etc/xinetd.d/tftp

change server_args = -s /var/lib/tftpboot
to server_args = -s /tftpboot

change disable=yes
to disable=no

mkdir /tftpboot
chmod 777 /tftpboot
systemctl restart xinetd
firewall-cmd --permanent --zone=public --add-port=69/udp
firewall-cmd --reload

Test ODBC

odbcinst -s -q

Use username & password in /etc/freepbx.conf to test connectivity to the DB via ODBC. 

isql -v MySQL-asteriskcdrdb freepbxuser somepassword

Test asterisk ODBC access

asterisk -vvvr
CLI> odbc show

Misc. settings

Set php memory_limit = 256M .

sed -i 's/memory_limit = .*/memory_limit = 256M/g' /etc/php.ini

systemctl restart httpd
