Install Asterisk on AlmaLinux 8

Step 1. First, let’s start by ensuring your system is up-to-date.

sudo dnf update
sudo dnf install epel-release
sudo dnf config-manager --set-enabled powertools
sudo dnf group install "Development Tools"
sudo dnf install git wget vim net-tools sqlite-devel psmisc ncurses-devel libtermcap-devel newt-devel libxml2-devel libtiff-devel gtk2-devel libtool libuuid-devel subversion kernel-devel kernel-devel-$(uname -r) crontabs cronie-anacron libedit libedit-devel

Step 2. Disable SELinux on the CentOS system.

Set SELinux in Permissive mode by running the commands below:

sudo setenforce 0
sudo sed -i 's/\(^SELINUX=\).*/\SELINUX=permissive/' /etc/selinux/config

Step 3. Setup Hostname.

Set the static hostname for your system using the following command:

sudo hostnamectl set-hostname asterisk.idroot.us

Next, we need to set the correct timezone for our system:

sudo timedatectl set-timezone Indonesia/Jakarta

Now download and install Jansson using the following command below:

sudo git clone https://github.com/akheron/jansson.git
cd jansson
autoreconf -i
./configure --prefix=/usr/

git clone https://github.com/pjsip/pjproject.git
cd pjproject
./configure CFLAGS="-DNDEBUG -DPJ_HAS_IPV6=1" --prefix=/usr --libdir=/usr/lib64 --enable-shared --disable-video --disable-sound --disable-opencore-amr
make dep
make
sudo make install
sudo ldconfig

sudo useradd -r -d /var/lib/asterisk -g asterisk asterisk
sudo usermod -aG audio,dialout asterisk
sudo chown -R asterisk.asterisk /etc/asterisk /var/{lib,log,spool}/asterisk /usr/lib64/asterisk

Then, set Asterisk default user:

sudo nano /etc/sysconfig/asterisk

Add the following file:

AST_USER="asterisk"
AST_GROUP="asterisk"

Also, edit/etc/asterisk/asterisk.conf file by using the below command:

sudo nano /etc/asterisk/asterisk.conf

Add the following command:

runuser = asterisk ; The user to run as.
rungroup = asterisk ; The group to run as.
