FusionPBX 5 Freeswitch 1.10 Debian 11 PostgreSQL Nginx Install Guide

Submitted by powerpbx on Sat, 02/11/2023 - 17:41

Fusionpbx is a full featured mult-tenant GUI for Freeswitch. This guide covers the installation of Fusionpbx and Freeswitch ® with PostgreSQL and NGINX on Debian 11.

Tested on:

Debian 11 (Bullseye) x64 minimal install
Freeswitch 1.10
FusionPBX 5
Nginx 1.1x
PHP 8.1
PostgreSQL 16

Assumptions:

Console text mode (multi-user.target)
Installation done as root user (su).

Prerequisites

Verify locale is set to C.UTF-8.

locale

If it is not then set it now.

# Select C.UTF-8 UTF-8
apt update && apt -y install locales && dpkg-reconfigure locales

Log out/in or close/open shell for changes to take effect. This should be done before PostgreSQL is installed.

Install base packages

apt update && apt upgrade -y && apt -y remove apache2

apt -y install wget git nano dbus sudo nginx curl dialog qrencode net-tools lsb-release sqlite3 haveged ghostscript libtiff5-dev libtiff-tools at tftpd ssl-cert gnupg2 software-properties-common

SNMP

apt install -y snmpd
echo "rocommunity public" > /etc/snmp/snmpd.conf
systemctl restart snmpd

IPtables

If ufw is not installed, you can ignore any resulting error.

apt install -y iptables
update-alternatives --set iptables /usr/sbin/iptables-legacy
update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
ufw --force disable && ufw --force reset && apt remove -y ufw

sngrep

wget http://packages.irontec.com/public.key -q -O - | apt-key add -
echo "deb http://packages.irontec.com/debian $(lsb_release -sc) main" > \
/etc/apt/sources.list.d/irontec.list

apt update && apt -y install sngrep

PostgreSQL

echo "deb http://apt.postgresql.org/pub/repos/apt/ $(lsb_release -sc)-pgdg main" > \
/etc/apt/sources.list.d/postgresql.list

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
apt update && apt install postgresql-16 postgresql-client-16

PHP

Install Dependencies

# Remove any existing PHP files
apt remove -y php*

# Install dependencies
apt -y install apt-transport-https ca-certificates

Add Repository

# Add php 8.1 repository
wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > \
/etc/apt/sources.list.d/php.list

Install

apt update && apt -y install php8.1 php8.1-cli php8.1-dev php8.1-fpm php8.1-pgsql php8.1-sqlite3 php8.1-odbc php8.1-curl php8.1-imap php8.1-xml php8.1-gd php8.1-mbstring php8.1-ldap

update-alternatives --set php /usr/bin/php8.1

Disable Firewall

It is sometimes helpful to disable the firewall during installation. If the packages are not installed or enabled, you can ignore any resulting errors.

systemctl disable firewalld
systemctl disable iptables
systemctl stop firewalld
systemctl stop iptables

Set Timezone

Using tzselect is one way to find the correct timezone.

## FIND YOUR TIMEZONE
tzselect

## SET TIMEZONE EXAMPLE
timedatectl set-timezone America/Vancouver

## CHECK TIMEZONE
timedatectl status

systemctl restart rsyslog

Install

Freeswitch

Get your signalwire token according to these instructions:
https://freeswitch.org/confluence/display/FREESWITCH/HOWTO+Create+a+SignalWire+Personal+Access+Token

Once you have your signalwire token install freeswitch packages

TOKEN=YOURSIGNALWIRETOKEN
 
apt-get update && apt-get install -y gnupg2 wget lsb-release
 
wget --http-user=signalwire --http-password=$TOKEN -O /usr/share/keyrings/signalwire-freeswitch-repo.gpg https://freeswitch.signalwire.com/repo/deb/debian-release/signalwire-freeswitch-repo.gpg
 
echo "machine freeswitch.signalwire.com login signalwire password $TOKEN" > /etc/apt/auth.conf

echo "deb [signed-by=/usr/share/keyrings/signalwire-freeswitch-repo.gpg] https://freeswitch.signalwire.com/repo/deb/debian-release/ `lsb_release -sc` main" > /etc/apt/sources.list.d/freeswitch.list

echo "deb-src [signed-by=/usr/share/keyrings/signalwire-freeswitch-repo.gpg] https://freeswitch.signalwire.com/repo/deb/debian-release/ `lsb_release -sc` main" >> /etc/apt/sources.list.d/freeswitch.list
 
apt update && apt install -y freeswitch-meta-all

Database

Check that localhost connections are always allowed. This is necessary for the backup script.

nano +125 /etc/postgresql/16/main/pg_hba.conf

host all all 127.0.0.1/32 trust

systemctl restart postgresql

Check PostgreSQL locale

sudo -u postgres psql -l

If Encoding is not UTF8 and Collate & Ctype is not C.UTF-8 then set it now.

sudo -u postgres psql

update pg_database set encoding = 6, datcollate = 'C.UTF-8', datctype = 'C.UTF-8' where datname = 'template0';
update pg_database set encoding = 6, datcollate = 'C.UTF-8', datctype = 'C.UTF-8' where datname = 'template1';

Create databases and user

cd /tmp

# Set the DB password variable.
password=fusionpbx

sudo -u postgres psql -c "SET client_encoding = 'UTF8';"
sudo -u postgres psql -c "CREATE DATABASE fusionpbx;" 
sudo -u postgres psql -c "CREATE DATABASE freeswitch;"
sudo -u postgres psql -c "CREATE ROLE fusionpbx WITH SUPERUSER LOGIN PASSWORD '$password';"
sudo -u postgres psql -c "CREATE ROLE freeswitch WITH SUPERUSER LOGIN PASSWORD '$password';"
sudo -u postgres psql -c "GRANT ALL PRIVILEGES ON DATABASE fusionpbx to fusionpbx;"
sudo -u postgres psql -c "GRANT ALL PRIVILEGES ON DATABASE freeswitch to fusionpbx;"
sudo -u postgres psql -c "GRANT ALL PRIVILEGES ON DATABASE freeswitch to freeswitch;"

Fusionpbx

There may be enhancements and fixes in our repository that are not in the official repository. We also strive to merge updates from the official repository on a regular basis.

mkdir -p /etc/fusionpbx
mkdir -p /var/www/fusionpbx
mkdir -p /var/cache/fusionpbx
git clone -b 5.1 https://github.com/powerpbx/fusionpbx.git /var/www/fusionpbx

Copy Directories

Replace default freeswitch conf files with fusionpbx conf files

mv /etc/freeswitch /etc/freeswitch.orig
mkdir /etc/freeswitch
cp -R /var/www/fusionpbx/app/switch/resources/conf/* /etc/freeswitch

Copy music directories to default location

mkdir -p /usr/share/freeswitch/sounds/music/default
mv /usr/share/freeswitch/sounds/music/*000/ /usr/share/freeswitch/sounds/music/default/

Enable services

systemctl daemon-reload
systemctl enable freeswitch
systemctl restart freeswitch

Browse to the public IP address of the server

http://xx.xx.xx.xx

to complete the install using the following:

Username: superadmin (or whatever you want)
Password: someSuperAdminPassword

Database Name: fusionpbx
Database Username: fusionpbx
Database Password: fusionpbx (The database user password created earlier)

The install may take a minute or two on slower servers.

Post install tasks are optional but recommended.

Post Install

Enable freeswitch database connection

This optional configuration changes FreeSWITCH's internal data storage from SQLite to PostgreSQL. SQLite is suitable for testing, troubleshooting, and moderate usage but may not be optimal for busy servers requiring high performance. Additionally, SQLite has a tendency to become corrupted if the server experiences an unclean shutdown.

nano +185 /etc/freeswitch/autoload_configs/switch.conf.xml

<param name="core-db-dsn" value="pgsql://hostaddr=127.0.0.1 dbname=freeswitch user=fusionpbx password='fusionpbx'" />

systemctl restart freeswitch

TFTP

If you plan to use hardware SIP phones you may want to enable TFTP.

Create tftp config

apt -y install xinetd

cat >> /etc/xinetd.d/tftp << EOF
service tftp
{
protocol        = udp
port            = 69
socket_type     = dgram
wait            = yes
user            = nobody
server          = /usr/sbin/in.tftpd
server_args     = /tftpboot
disable         = no
}
EOF

Make the directory and restart the daemon to start tftp.

mkdir /tftpboot
chmod 777 /tftpboot
systemctl restart xinetd

firewall-cmd --permanent --zone=public --add-port=69/udp
firewall-cmd --reload

Go to GUI Advanced > Default Settings > Provision. About 20 rows down set enabled = Trueand reload

Add a new subcategory in Provision category by pressing the + icon and fill in as follows:

Category = provision
Subcategory = path
type = text
Value = /tftpboot
Enabled = True

systemctl restart fail2ban

If connecting from external LANs, it is a good idea to add their public IP addresses in fail2ban to prevent accidental banning of the entire LAN.

nano /etc/fail2ban/jail.conf

# "ignoreip" can be a list of IP addresses, CIDR masks or DNS hosts. Fail2ban
# will not ban a host which matches an address in this list. Several addresses
# can be defined using space (and/or comma) separator.
[DEFAULT]
ignoreip = 127.0.0.1/8 ::1

systemctl restart fail2ban

Email Queue

cp /var/www/fusionpbx/app/email_queue/resources/service/debian.service /etc/systemd/system/email_queue.service
systemctl daemon-reload
systemctl enable email_queue
systemctl start email_queue

Event Guard

cp /var/www/fusionpbx/app/event_guard/resources/service/debian.service /etc/systemd/system/event_guard.service
systemctl daemon-reload
systemctl enable event_guard
systemctl start event_guard

Troubleshooting the Dialplan

To view the dyamically generated xml files.
