This brief tutorial shows students and new users how to install FreePBX on Ubuntu 18.04 | 16.04.
FreePBX is an open-source, web-based application that can be used to manage Asterisk (PBX) platform. We recently showed you how to install Asterisk on Ubuntu.
When you install Asterisk, you’ll get a terminal console where you can manage the system. The problem with managing Asterisk via the terminal is, it can be very difficult to configure complicated phone trees via the terminal.
For a simple-to-use interface, install FreePBX. This post is going to show you how to install FreePBX to manage Asterisk.
To get started with managing FreePBX, follow the steps below:
Install Asterisk PBX
Since you’re going to be managing Asterisk, your first task will be to install it. The good thing is, we’ve shown our users how to install Asterisk on Ubuntu.
Below is a tutorial that showed you how to install Asterisk on Ubuntu.
How to install Asterisk PBX on Ubuntu Linux
After installing the Asterisk above, continue below to install and configure FreePBX.
Apache HTTP Server
Apache2 HTTP Server is the most popular web server in use. so install it since FreePBX needs it.
To install Apache2 HTTP on the Ubuntu server, run the commands below.
sudo apt update sudo apt install apache2
After installing Apache2, the commands below can be used to stop, start and enable the Apache2 service to always start up with the server boots.
sudo systemctl stop apache2.service sudo systemctl start apache2.service sudo systemctl enable apache2.service
To find out if the Apache2 HTTP server is installed, simply open your web browser and type in the server’s IP or hostname.
When you see a page similar to the one below, then Apache2 is installed and working.
http://localhost

After that, run the commands below to remove the Apache2 default index.html file.
sudo rm /var/www/html/index.html
Install MariaDB Database Server
FreePBX also needs a database server to store its content. and MariaDB database server is a great place to start when looking at open-source database servers to use with FreePBX.
To install MariaDB run the commands below.
sudo apt install mariadb-server mariadb-client
After installing MariaDB, the commands below can be used to stop, start and enable the MariaDB service always to start up when the server boots.
Run these on Ubuntu
sudo systemctl stop mariadb.service sudo systemctl start mariadb.service sudo systemctl enable mariadb.service
After that, run the commands below to secure the MariaDB server by creating a root password and disallowing remote root access.
sudo mysql_secure_installation
When prompted, answer the questions below by following the guide.
- Enter current password for root (enter for none): Just press the Enter
- Set root password? [Y/n]: Y
- New password: Enter password
- Re-enter new password: Repeat password
- Remove anonymous users? [Y/n]: Y
- Disallow root login remotely? [Y/n]: Y
- Remove test database and access to it? [Y/n]: Y
- Reload privilege tables now? [Y/n]: Y
Restart MariaDB server
To test if MariaDB is installed, type the commands below to logon into the MariaDB server
sudo mysql -u root -p
To test if MariaDB is installed and working, run the commands below:
sudo systemctl status mariadb
That should display MariaDB’s service status.
● mariadb.service - MariaDB 10.1.44 database server Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2020-04-08 17:08:17 CDT; 1min 54s ago Docs: man:mysqld(8) https://mariadb.com/kb/en/library/systemd/ Main PID: 22363 (mysqld)
By default, on Ubuntu, MariaDB is configured to use the UNIX auth_socket plugin. You’ll want to run the SQL commands below for the root user to use mysql_native_password.
You’ll need a MariaDB root account to set up FreePBX later.
Run the commands below to log on to MariaDB. When prompted for a password, type the root password you created above.
sudo mysql -u root -p
Switch to the MySQL database.
use mysql;
Then update the root account to use mysql_native_password.
UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE User = 'root';
Finally, save your changes and exit.
FLUSH PRIVILEGES; EXIT;
Install PHP 7.2 and Related Modules
PHP 7.2 may not be available in Ubuntu default repositories. to install it, you will have to get it from third-party repositories.
Run the commands below to add the below third-party repository to upgrade to PHP 7.2
sudo apt-get install software-properties-common sudo add-apt-repository ppa:ondrej/php
Then update and upgrade to PHP 7.2
sudo apt update
Next, run the commands below to install PHP 7.2 and related modules.
sudo apt install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-mysql php7.2-gd php7.2-imap php7.2-ldap php-cas php7.2-bcmath php7.2-xml php7.2-cli php7.2-zip php7.2-sqlite3
After installing PHP 7.2, run the commands below to open the PHP default config file for Apache2.
sudo nano /etc/php/7.2/apache2/php.ini
Then make the changes on the following lines below in the file and save. The value below is a great setting to apply in your environment.
file_uploads = On allow_url_fopen = On short_open_tag = On memory_limit = 256M upload_max_filesize = 100M max_execution_time = 360 max_input_vars = 1500 date.timezone = America/Chicago
After making the change above, save the file and close it.
To test PHP 7.2 settings with Apache2, create a phpinfo.php file in the Apache2 root directory by running the commands below
sudo nano /var/www/html/phpinfo.php
Then type the content below and save the file.
<?php phpinfo( ); ?>
Save the file. then browse to your server hostname followed by /phpinfo.php
http://localhost/phpinfo.php
You should see the PHP default test page.

Install Nodejs
After installing the server above, run the commands below to add Nodejs 10 repository to Ubuntu
sudo apt update sudo apt install curl dirmngr apt-transport-https lsb-release ca-certificates curl -sL https://deb.nodesource.com/setup_10.x | sudo bash
Then run the commands below to install Nodejs.
sudo apt-get install gcc g++ make sudo apt install nodejs
Install FreePBX
At this point, you should have everything ready for FreePBX. To download and install FreePBX, run the commands below:
sudo apt install wget cd /tmp wget http://mirror.freepbx.org/modules/packages/freepbx/freepbx-15.0-latest.tgz tar xfz freepbx-15.0-latest.tgz
Finally, run the commands below to install.
cd freepbx sudo ./start_asterisk start sudo ./install -n --dbuser root --dbpass type_root_password_here
If you get an error,
Error!
Unable to read /etc/asterisk/asterisk.conf or it was missing a directories section
run the commands below to resolve:
sudo cp /etc/asterisk/asterisk.conf.old /etc/asterisk/asterisk.conf
If you also get an error:
‘asterisk’ user…bash: line 0: cd: /home/asterisk/: No such file or directory
Run the commands below to resolve:
sudo mkhomedir_helper asterisk
When you have resolved all the errors above, go back and try the installation again.
After installing, you should get a similar message as shown below:
Updating Hooks…Done Done installing all modules Taking too long? Customize the chown command, See http://wiki.freepbx.org/display/FOP/FreePBX+Chown+Conf Setting Permissions… Setting base permissions…Done Setting specific permissions… 11864 [============================] Finished setting permissions Taking too long?

HEEELP!!! )))
You probably have multiple versions of php installed. check in /etc/php. If you have 7.2 and 7.4, you either run sudo apt install php7.4-xml or
1. apt-get purge php7.*
2. apt-get install -y php7.2
3. apt-get install -y php7.2-xml
the latter is preferred, i discovered php7.4 caused an error during the freepbx installation.
cd to /etc/php and see which versions of PHP are installed. In my case, I had 7.2 and 7.4 apparently.
sudo apt install php7.x-xml – where 7.x are the versions listed in /etc/php. You should find that the XML extension for one of the versions wasn’t installed. This should fix your problem.
Hi, i have this problem “The command “/usr/sbin/fwconsole chown” failed.” after i wrote sudo ./install -n –dbuser root –dbpass (pass)
Can anyone help me?
Thanks a lot
Do the following:
1. apt-get purge php7.*
2. apt-get install -y php7.2
3. apt-get install -y php7.2-xml
4. apt-get install -y php7.2-mysql
5. sudo ./install -n –-dbuser root –-dbpass (pass)
It works! Thanks
Worked for me

Could you please help
Same issue for me. Would really like some help with this please.
Hi, i’ve followed the procedures but http://localhost/admin/config.php is a white page
I am getting the same thing, no errors during the entire process other than the ones outlined above, and by using the procedures I was able to get past the point where I was getting hung up previously, but when i go to http://localhost/ i get auto-redirected to http://localhost/admin/config.php, which is a blank (white with no text) website. I am running Ubuntu 20.04.
Hi, i’ve followed the procedures but http://localhost/admin/config.php is a white page with HTTP ERROR 500
Same for me…
Hello mates, I have been investigating about that error (because I have it too) and I found some interesting information in this link:
https://community.freepbx.org/t/yet-another-error-500-on-fresh-install/16731/11
Maybe something could work.
Please if someone tries it, tell us how to solve that error.
Also, in my investigation i got an answer that maybe the time zone hast to be changed
If you are on Ubuntu 20.04. installing php 7.4 worked for me. I used:
sudo apt install php
sudo sed -i ‘s/\(^upload_max_filesize = \).*/\120M/’ /etc/php/7.4/apache2/php.ini
sudo sed -i ‘s/\(^upload_max_filesize = \).*/\120M/’ /etc/php/7.4/cli/php.ini
sudo a2enmod rewrite
sudo systemctl restart apache2
i meet the same problem with,Did you solve it?
Everything worked but http://localhost/admin/config.php is blank. Can anyone help? Thx
same for me, help us
Thanks
+1
For me, the error 500 looks like it is caused by a permissions issue. I have checke the file called error.log located in /var/log/apache2/ and it says PHP Warning: include_once(/etc/freepbx.conf): failed to open stream: Permission denied in /var/www/html/admin/config.php on line 126
Still researching on a solution
sudo chmod 664 /etc/freepbx.conf
sudo ufw allow proto tcp from any to any port 80,443
sudo add-apt-repository ppa:ondrej/php
Not working, have you an alternative?
Anyone find a solution here? My /admin/config.php is also giving me a HTTP ERROR 500
I do the same this page , it working but http://localhost/admin/config.php is blank please help me !!!
I’m on ubuntu 18.04 and 127.0.0.1 redirects to blank page 🙁

https://stackoverflow.com/questions/38839544/php-is-missing-mysql-pdo-driver
for the blank page and permission denied on error log, you can try this one
/etc/apache2/envvars
change this line
# export APACHE_RUN_USER=www-data
# export APACHE_RUN_GROUP=www-data
export APACHE_RUN_USER=asterisk
export APACHE_RUN_GROUP=asterisk
Excellent… Good.
Works for me thanks a lot
This is the perfect solution.
There’s quite a few problems with this guide.
1. I had to use PHP 7.3 to avoid installation issues. Both 7.2 and 7.4 gave errors.
2. The biggest mistake in the instructions is including php-cas in the php installs. This will by default install PHP 7.4 as well, causing conflicts if you are using another version of PHP.
3. Basically for people starting out with this, make sure whatever PHP library you install, it should coincide with your particular PHP version. Otherwise it will break stuff.
Good luck guys, don’t give up! It works. I encountered almost every error mentioned in the comments and managed to fix them all.
If you get a blank screen try setting the permissions again:
sudo chmod 777 /var/www/html
sudo chmod 777/var/log/asterisk
Worked for me 🙂
didnt work
This doesn’t work at all. I was excited to have a PBX, I could spoof calls with scammers. I’m a scambaiting in need of a PBX on my VPS. They don’t allow mounting, but I need some help. Since I can’t get this guild to work, almost at my ends wits with this stuff. if anyone to could reach out to me with help, I would be in debt to you and also will share the spoofing macro with you.
http://localhost/admin/config.php is a blank screen
I do everything according to the instructions but I have php version 8.0.11
After successfully installation, http://localhost/admin/config.php shows a blank page. Could anyone help please?
Thanks
