Installing FreePBX 13 on CentOS 7
READ FIRST
Manual installations of FreePBX is considered an EXPERTS ONLY exercise. This method of installation is enough to get CORE functionality of FreePBX. Non-commercial modules may not function as expected or detailed in the Wiki's. Certain modules and features may require additional software to be installed and configured on the server.
**** COMMERCIAL MODULES CANNOT BE INSTALLED ON THIS OS ****
Install Centos 7
Initial System Setup
You MUST run all of these commands as the root user!
You MUST disable selinux. selinux can cause strange behavior during the install
Disable selinux
In /etc/sysconfig/selinux , change the following lines:
sed -i 's/\(^SELINUX=\).*/\SELINUX=disabled/' /etc/sysconfig/selinux sed -i 's/\(^SELINUX=\).*/\SELINUX=disabled/' /etc/selinux/config |
reboot, and verify the selinux status by running 'sestatus'. It should say:
SELinux status: disabled |
Update Your System
yum -y update yum -y groupinstall core base "Development Tools" |
Install Additional Required Dependencies
yum -y install lynx mariadb-server mariadb php php-mysql php-mbstring tftp-server \ httpd ncurses-devel sendmail sendmail-cf sox newt-devel libxml2-devel libtiff-devel \ audiofile-devel gtk2-devel subversion kernel-devel git php-process crontabs cronie \ cronie-anacron wget vim php-xml uuid-devel sqlite-devel net-tools gnutls-devel php-pear unixODBC mysql-connector-odbc |
Install Legacy Pear requirements
pear install Console_Getopt |
Firewalld Basic Configuration
You must open port 80 so that you can access the administration interface
firewall-cmd --zone=public --add-port=80/tcp --permanent firewall-cmd --reload |
Enable and Start MariaDB
You must have MariaDB running for freepbx to operate normally. It must start automatically, and be running continuously.
systemctl enable mariadb.service systemctl start mariadb |
Now that our MariaDB database is running, we want to run a simple security script that will remove some dangerous defaults and lock down access to our database system a little bit
mysql_secure_installation |
The prompt will ask you for your current root password. Since you just installed MySQL, you most likely won’t have one, so leave it blank by pressing enter. Then the prompt will ask you if you want to set a root password. Do not set a root password. We secure the database automatically, as part of the install script. Apart from that you can chose yes for the rest. This will remove some sample users and databases, disable remote root logins, and load these new rules so that MySQL immediately respects the changes we have made.
Enable and Start Apache
FreePBX uses the Apache web server, so this must be started and running.
systemctl enable httpd.service systemctl start httpd.service |
Install Dependencies for Google Voice (if required)
Install iksemel
cd /usr/src wget https://iksemel.googlecode.com/files/iksemel-1.4.tar.gz tar xf iksemel-*.tar.gz rm -f iksemel-1.4.tar.gz cd iksemel-* ./configure make make install |
Add the Asterisk User
adduser asterisk -m -c "Asterisk User" |
Install and Configure Asterisk
Download Asterisk source files.
cd /usr/src wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz wget http://downloads.asterisk.org/pub/telephony/libpri/libpri-current.tar.gz wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-13-current.tar.gz wget -O jansson.tar.gz https://github.com/akheron/jansson/archive/v2.7.tar.gz wget http://www.pjsip.org/release/2.4/pjproject-2.4.tar.bz2 |
Compile and install DAHDI
If you don't have any physical PSTN hardware attached to this machine, you don't need to install DAHDI (For example, a T1 or E1 card, or a USB device). Most smaller setups will not have DAHDI hardware, and this step can be safely skipped.
cd /usr/src tar xvfz dahdi-linux-complete-current.tar.gz tar xvfz libpri-current.tar.gz rm -f dahdi-linux-complete-current.tar.gz libpri-current.tar.gz cd dahdi-linux-complete-* make all make install make config cd /usr/src/libpri-* make make install |
Compile and install pjproject
cd /usr/src tar -xjvf pjproject-2.4.tar.bz2 rm -f pjproject-2.4.tar.bz2 cd pjproject-2.4 CFLAGS='-DPJ_HAS_IPV6=1' ./configure --prefix=/usr --enable-shared --disable-sound\ --disable-resample --disable-video --disable-opencore-amr --libdir=/usr/lib64 make dep make make install |
Compile and Install jansson
cd /usr/src tar vxfz jansson.tar.gz rm -f jansson.tar.gz cd jansson-* autoreconf -i ./configure --libdir=/usr/lib64 make make install |
Compile and install Asterisk
BUG:
Some versions of Asterisk will crash with a missing ari.conf https://issues.asterisk.org/jira/browse/ASTERISK-27026
You may wish to "mkdir -p /etc/asterisk && touch /etc/asterisk/ari.conf" after compiling Asterisk
cd /usr/src tar xvfz asterisk-13-current.tar.gz rm -f asterisk-13-current.tar.gz cd asterisk-* contrib/scripts/install_prereq install ./configure --libdir=/usr/lib64 contrib/scripts/get_mp3_source.sh make menuselect |
You will be prompted at the point to pick which modules to build. Most of them will already be enabled, but if you want to have MP3 support (eg, for Music on Hold), you need to manually turn on 'format_mp3' on the first page.
After selecting 'Save & Exit' you can then continue
make make install make config ldconfig chkconfig asterisk off |
Install Asterisk Soundfiles.
The 'make install' above installs a standard low-quality base sound file by default. This is suitable if you are on a small, underpowered system (such as a Rasberry Pi), but on a larger system you should install higher quality soundfiles. Note that this installs the (8khz) 'wav' soundfiles and G722 (High Definition 'Wideband') audio.
cd /var/lib/asterisk/sounds wget http://downloads.asterisk.org/pub/telephony/sounds/asterisk-core-sounds-en-wav-current.tar.gz wget http://downloads.asterisk.org/pub/telephony/sounds/asterisk-extra-sounds-en-wav-current.tar.gz tar xvf asterisk-core-sounds-en-wav-current.tar.gz rm -f asterisk-core-sounds-en-wav-current.tar.gz tar xfz asterisk-extra-sounds-en-wav-current.tar.gz rm -f asterisk-extra-sounds-en-wav-current.tar.gz # Wideband Audio download wget http://downloads.asterisk.org/pub/telephony/sounds/asterisk-core-sounds-en-g722-current.tar.gz wget http://downloads.asterisk.org/pub/telephony/sounds/asterisk-extra-sounds-en-g722-current.tar.gz tar xfz asterisk-extra-sounds-en-g722-current.tar.gz rm -f asterisk-extra-sounds-en-g722-current.tar.gz tar xfz asterisk-core-sounds-en-g722-current.tar.gz rm -f asterisk-core-sounds-en-g722-current.tar.gz |
Set Asterisk ownership permissions.
chown asterisk. /var/run/asterisk
chown -R asterisk. /etc/asterisk
chown -R asterisk. /var/{lib,log,spool}/asterisk
chown -R asterisk. /usr/lib64/asterisk
chown -R asterisk. /var/www/

Install and Configure FreePBX
A few small modifications to Apache.
sed -i 's/\(^upload_max_filesize = \).*/\120M/' /etc/php.ini sed -i 's/^\(User\|Group\).*/\1 asterisk/' /etc/httpd/conf/httpd.conf sed -i 's/AllowOverride None/AllowOverride All/' /etc/httpd/conf/httpd.conf systemctl restart httpd.service |
Download and install FreePBX.
cd /usr/src wget http://mirror.freepbx.org/modules/packages/freepbx/freepbx-13.0-latest.tgz tar xfz freepbx-13.0-latest.tgz rm -f freepbx-13.0-latest.tgz cd freepbx ./start_asterisk start ./install -n |
That's it!
You can now start using FreePBX. Open up your web browser and connect to the IP address or hostname of your new FreePBX server. You will see the Admin setup page, which is where you set your 'admin' account password, and configure an email address to receive update notifications.
We hope you enjoy using FreePBX 13!
Automatic Startup
Please note you need to set up FreePBX to start asterisk (and it's associated services) on bootup. You can view an example systemd startup script here.
