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 apt install linux-headers*

Asterisk

To install Asterisk v14, set VERSION=14 .  To switch versions, it is best to run  rm -rf /usr/lib64/asterisk/modules first.

# Select Asterisk VERSION=14 or
VERSION=13
cd /usr/src
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-${VERSION}-current.tar.gz
tar zxvf asterisk-${VERSION}-current.tar.gz
cd /usr/src/asterisk-${VERSION}*/
make distclean

Install additional dependencies

cd /usr/src/asterisk-${VERSION}*/
./contrib/scripts/install_prereq install

Configure

cd /usr/src/asterisk-${VERSION}*/
./configure --libdir=/usr/lib64 --with-pjproject-bundled

To view results type nano -v config.log.

Set compile options

cd /usr/src/asterisk-${VERSION}*/
make menuselect

# Select additional compile options or leave at default and save.
# 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 /sbin/nologin -c "Asterisk User"
make && make install && chown -R asterisk. /var/lib/asterisk

Freepbx

systemctl restart mariadb
cd /usr/src
git clone -b release/14.0 --single-branch https://github.com/freepbx/framework.git freepbx
cd /usr/src/freepbx
./start_asterisk start

./install -n

If you get a Could not determine Asterisk version error do the following: 

# Replace line 266 of freepbx/installlib/installcommand.class.php to be like the following:

$lastline = exec("runuser" . $answers['user'] . ' -s /bin/bash -c "cd ~/ && asterisk -rx \'core show version\' | grep ^Asterisk 2>&1"', $tmpout, $ret);

Module install

fwconsole ma upgrade framework core voicemail sipsettings infoservices \
featurecodeadmin logfiles callrecording cdr dashboard music conferences
fwconsole chown
fwconsole reload

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

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

fwconsole ma installall
fwconsole chown
fwconsole reload

Set 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
ExecStop=/usr/sbin/fwconsole stop
 
[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

Make sure database and web server are set to start on boot.

systemctl enable mariadb
systemctl enable httpd

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/*log
/var/log/asterisk/full
/var/log/asterisk/dtmf
/var/log/asterisk/freepbx_dbug
/var/log/asterisk/fail2ban {
        weekly
        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
}

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/asterisk/res_odbc_additional.conf to test connectivity to the DB via ODBC. 

isql -v MySQL-asteriskcdrdb someusername 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
