Installing and Configuring Asterisk CentOS 7

You will need a Linux OS to install Asterisk.



The above is version 7 32 or 64 depending on CPU and is a minimal install


  • Stuff to do once Linux OS is installed
  • vi /etc/sysconfig/network-scripts/ifcfg-eth0
  • Make sure onboot=yes change that from disabled
  • service network restart
  • ip addr show ( should show an ip address for eth0 )
  • yum -y update ( update the system without prompting )
  • shutdown -r now ( reboot system after updating to apply )
  • cd /usr/src
  • yum -y install wget ( install wget package to download files from the internet)
  • You can either wget Asterisk from up above or use CentOS repos to install Asterisk ( A word of caution is to make sure it is a LTS version or certified version of Asterisk)
  • yum method: yum -y install asterisk ( this will install asterisk with all dependencies )
  • It is also a good idea with CentOS to install the epel-release repo
  • yum -y install epel-release; yum repolist ( should install the epel-release and then list repos and should see epel)
  • If you download asterisk using wget
  • wget url-for-asterisk.tgz
  • tar zxfv name.of.file.tgz
  • cd name.of.folder
  • ** Have to install some custom files to run asterisk if you just run ./configure it’ll error out and complain**
  • yum -y install gcc gcc-c++ libxml2-devel sqlite-devel ncurses-devel
  • ./configure
  • make menuselect
  • make
  • make install
  • make samples ( install sample configuration files )
  • Have Asterisk start as a service
  • cd /usr/src/name-of-folder; cp contrib/init.d/rc.redhat.asterisk /etc/init.d/asterisk
  • vi /etc/init.d/asterisk ( locate AST_SBIN= ) replace that with AST_BIN=/usr/sbin/
  • service asterisk start ( if it complains about 64bit libraries do the following)
  • ┬áln -s /usr/lib/ /usr/lib64/ ( only if it complaines about 64bit .so file)
  • Disable selinux by vi /etc/selinux/config ( change SELINUX=enabled to SELINUX=disabled
  • shutdown -r now ( need to reboot otherwise selinux will enforce still )
  • chkconfig asterisk on ( enable to start on reboot ) or if chkconfig does not exist because of systemctl then use systemctl enable asterisk
  • systemctl status iptables or service iptables status ( if iptables is running need to disable )
  • systemctl disable iptables ( or firewalld ) service iptables stop systemctl stop iptables
  • chkconfig iptables off systemctl disable firewalld
