CentOS 5 and Asterisk 1.4.x installation





CentOS 5 and Asterisk 1.4.x installation



Base Install of Asterisk on an i386 CentOS


For reasons detailed elsewhere, you're best not using a GUI, so do the installation from the command line ('linux-text' at the GRUB prompt). When you select the packages, the only one you need is 'server'. Disk partitioning, networking etc. is all entirely up to you!



At your first login, you'll be presented with a simple administration screen. Disable SELinux and (for now) the firewall.

Dependencies




The first thing to do is to get your box up to date. If you have CentOS 5.1 or lower, you may want to upgrade to CentOS 5.2. Try:



yum -y upgrade



and then reboot. Otherwise, to update all the installed packages, at the shell, run



yum -y update



When you've done either of the above, reboot the machine when it's finished (as it'll install a new kernel) and then run



yum -y update


again and repeat until there are no more updates.



Quick method:


Do you trust me? If so, the line below will install all the dependencies you need (and then some!) - cut and paste from here if you're happy to install things you may or may not need. If not, then have a look at this page's history as some of the dependencies are listed separately.

Download and install Asterisk and components


Download


Download the latest asterisk version /usr/src/asterisk and untar the files as follows:

mkdir -p /usr/src/asterisk

cd /usr/src/asterisk

wget http://downloads.digium.com/pub/asterisk/asterisk-1.4-current.tar.gz

wget http://downloads.digium.com/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz

wget http://downloads.digium.com/pub/libpri/libpri-1.4-current.tar.gz

wget http://soft-switch.org/downloads/spandsp/spandsp-0.0.5.tgz

tar -zxf dahdi-linux-complete-current.tar.gz

tar -zxf asterisk-1.4-current.tar.gz

tar -zxf libpri-1.4-current.tar.gz

tar -zxf spandsp-0.0.5.tgz



You'll end up with four tar files and four directories in the directory '/usr/src/asterisk'.



SpanDSP (optional)


cd /usr/src/asterisk/spandsp-0.0.5

make clean

./configure

make

make install

cat > /etc/ld.so.conf.d/spandsp.conf << EOF

/usr/local

EOF

ldconfig





Libpri (optional)


If you are using E1 cards you need to install LIBPRI. If you do want to use LIBPRI, make sure you compile and install it before you compile Asterisk. Replace 'VERSION' with the correct details.

cd /usr/src/asterisk/libpri-VERSION

make clean

make

make install





DAHDI


You're pretty much going to need DAHDI. If not for any hardware then for the dummy timer anyway. Note that the stock CentOS kernels come with a 1000HZ timer and so don't need recompiling (phew!). Replace 'VERSION' with the correct details.

cd /usr/src/asterisk/dahdi-linux-complete-VERSION

make all

make install

make config



Edit /etc/dahdi/modules.conf, /etc/dahdi/system.conf and /etc/asterisk/chan_dahdi.conf for your site.

Set DAHDI to start automatically and then start it.

chkconfig dahdi on

service dahdi start





Asterisk


cd /usr/src/asterisk/asterisk-VERSION

make clean

./configure



Choose which options to install (audio files, voicemail storage, codecs etc.)

make menuselect

make

make install



Install sample files in /etc/asterisk, install docs/manpages and set to start on boot.

make samples

make progdocs

make config

chkconfig asterisk on



Check Asterisk starts properly:

asterisk -vvvvvvvvvvvvvvvvvvvc

stop now



If not, you've probably not been following these instructions carefully! Assuming it does start properly, you probably want to start it in the background:

service asterisk start



Then edit the following files in /etc/asterisk:

indications.conf - Change default country

modules.conf - Uncomment the line 'preload => res_odbc.so'

modules.conf - Add 'noload => pbx_ael.so' to bottom of file

modules.conf - Add 'noload => codec_dahdi.so' to the bottom of the file



Tidy up a bit (you can cut and paste all of this to the command line)

Configure MySQL (optional)


The information below shows table definitions for all of the tables Asterisk can use with MySQL or ODBC.



Notes


The UniqueID field in the CDR table is not necessarily unique! Due to the very very dodgy way Asterisk handles unique IDs, if you set the field to be the primary key (as advised elsewhere), you will lose data.



SQL


Note that the SIP 'qualify' field has a default value set to 'yes'. This is for two reasons. Firstly, I wrote these notes because it's how I use and want to use Asterisk. Secondly, whether qualification is enabled or not in realtime is controlled by the 'rtcachefriends' setting in sip.conf - if it's 'no', then whether 'qualify' is 'yes' or 'no' in the database is irrelevant. It makes sense therefore to enable it in the database and then turn it on or off with the 'rtcachefriends' setting.



SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";
