This is a short video tutorial on the installation of Asterisk 11, I have included the blog and video in one place for ease of viewing
First, you will want to be sure that your server OS is up to date.
yum update -y
Disable SELinux by changing “enforcing” to “disabled” in /etc/selinux/config. Use a text editor or copy and paste this command.
sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config
After you update and disable SELinux, you’ll need to reboot.
Next, you will want to resolve basic dependencies. (More information on Asterisk dependencies.)
yum install -y make wget openssl-devel ncurses-devel newt-devel libxml2-devel kernel-devel gcc gcc-c++ sqlite-devel
Change into the /usr/src/ directory to store your source code.
Download the source tarballs. These commands will get the current release of DAHDI 2.6, libpri 1.4 and Asterisk 11.
Extract the files from the tarballs.
tar zxvf dahdi-linux-complete*
tar zxvf libpri*
tar zxvf asterisk*
For the next set of commands it is important to follow the proper order: DAHDI first, then libpri, then Asterisk.
make && make install && make config
make && make install
Change to the Asterisk directory.
In the next step, running the “configure” script will vary depending on whether your system is 32-bit or 64-bit. (Watch the video for more details.) When the menuselect command runs, select your options, then choose “Save and Exit” and the install will continue.
Use this command if you are installing Asterisk on 32bit CentOS.
./configure && make menuselect && make && make install
Use this command if you are installing Asterisk on 64bit CentOS.
./configure --libdir=/usr/lib64 && make menuselect && make && make install
Optional: If you ran into errors you will want to clean the install directory before recompiling.
make clean && make distclean
Once you have an error-free install, copy the sample files from the configs subdirectory into /etc/asterisk.
Then add the Asterisk start script to the /etc/init.d/ directory
service dahdi start
service asterisk start
Connect to the Asterisk CLI.
And now you have Asterisk 11 running on CentOS 6!
