Installing a binary distribution of Asterisk makes it easier to maintain your system. Using the package management tools that are included with your Linux distribution, you can install and update software without manually managing dependencies (libraries and utilities on which applications rely). Currently Asterisk is available for automated binary installation using the ‘yum’ utility on CentOS 5 Linux and for RedHat Enterprise Linux 5.
The first step is to add the Asterisk yum repositories to your CentOS or RedHat system. This is done by creating an entry in the yum configuration directory (/etc/yum.repos.d by default).
Use the text editor of your choice to create a new file named “centos-asterisk.repo” in the “/etc/yum.repos.d” folder. Add the following text to the file:
[asterisk-tested] name=CentOS-$releasever - Asterisk - Tested baseurl=http://packages.asterisk.org/centos/$releasever/tested/$basearch/ enabled=0 gpgcheck=0 #gpgkey=http://packages.asterisk.org/RPM-GPG-KEY-Digium [asterisk-current] name=CentOS-$releasever - Asterisk - Current baseurl=http://packages.asterisk.org/centos/$releasever/current/$basearch/ enabled=1 gpgcheck=0 #gpgkey=http://packages.asterisk.org/RPM-GPG-KEY-Digium
Save the new file and create another named “centos-digium.repo” and insert the following text:
[digium-tested] name=CentOS-$releasever - Digium - Tested baseurl=http://packages.digium.com/centos/$releasever/tested/$basearch/ enabled=0 gpgcheck=0 #gpgkey=http://packages.digium.com/RPM-GPG-KEY-Digium [digium-current] name=CentOS-$releasever - Digium - Current baseurl=http://packages.digium.com/centos/$releasever/current/$basearch/ enabled=1 gpgcheck=0 #gpgkey=http://packages.digium.com/RPM-GPG-KEY-Digium
At this point your system has been updated to use the Asterisk and Digium repositories in addition to the base CentOS repositories. You are now ready to install Asterisk. To star the installation, execute the following at the Linux command line:
[root@localhost~]# yum install asterisk16 asterisk16-configs asterisk16-voicemail dahdi-linux dahdi
Once its completed so your installation is complete
