CentOS 5.2 and Asterisk 1.6.x installation

Reference : http://www.voip-info.org/wiki/view/CentOS+5.2+and+Asterisk+1.6.x+installation

This is a work in progress - copied from my CentOS 5 and Asterisk 1.4.x installation page

Base Install of Asterisk on an i386 CentOS/RHEL box:

More as an aide memoir for us than anything else, but if somebody does find it useful, then that's good too!

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. 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.

yum -y install gcc gcc-c++ kernel-devel bison \
openssl openssl-devel perl perl-Net-SSLeay perl-Crypt-SSLeay \
libtermcap-devel ncurses-devel doxygen curl-devel newt-devel \
mlocate lynx tar wget nmap bzip2 mod_ssl crontabs vixie-cron \
speex speex-devel unixODBC unixODBC-devel libtool-ltdl \
libtool-ltdl-devel mysql-connector-odbc mysql mysql-devel \
mysql-server php-mysql php-mbstring php-mcrypt flex screen \
libtiff-devel

Individual application specific dependencies

Asterisk

We've got to be able to compile it!

yum -y install gcc gcc-c++

Note that you may need to use the following if you are running a Xen enabled kernel:

yum -y install kernel-xen-devel

If you want the 'zttool' application, you'll need to:

yum -y install newt-devel

Other things you may find useful (if they're not already installed):

yum -y install mlocate lynx tar wget nmap bzip2 mod_ssl crontabs vixie-cron

Speex (optional)

Speex support depends on 'speex_preprocess_ctl' which is not available in the standard Speex packages. It may be possible to compile an older version of Speex if required.

ODBC stuff (optional)

Note that if you have already installed Asterisk, you will need to run 'configure', 'make' and 'make install' to detect ODBC and compile it in.

yum -y install unixODBC unixODBC-devel libtool-ltdl libtool-ltdl-devel

MySQL ODBC interface/connector (optional, but required if using ODBC and MySQL)

yum -y install mysql-connector-odbc

And then edit the file '/etc/odbcinst.ini' (or '/usr/local/odbcinst.ini') and replace 'Driver = /usr/lib/libmyodbc.so' with 'Driver = /usr/lib/libmyodbc3.so'

MySQL (optional)

yum -y install mysql mysql-devel mysql-server
chkconfig mysqld on
service mysqld start

PHPMyAdmin (optional)

Download the latest version from http://www.phpmyadmin.net/, unzip/unbzip/untar into /var/www/htdocs/phpmyadmin (for the time being). Make sure Apache starts on boot.

yum -y install php-mysql php-mbstring php-mcrypt
chkconfig httpd on
service httpd start

Surf to https://i.p.address/phpmyadmin and check it works.

Webmin (optional)

If SSL is required, ensure that the correct bits are installed

yum -y install openssl openssl-devel perl perl-Net-SSLeay perl-Crypt-SSLeay

Download the latest version of the RPM from http://www.webmin.com/

rpm -i webmin-VERSION
chkconfig webmin on
service webmin start

Surf to https://i.p.address:10000 and check it works.

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.asterisk.org/pub/telephony/asterisk/asterisk-1.6.1-current.tar.gz
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-addons-1.6.1-current.tar.gz
wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz
wget http://soft-switch.org/downloads/spandsp/spandsp-0.0.6pre18.tgz (or most current version)
wget http://downloads.digium.com/pub/libpri/libpri-1.4-current.tar.gz
tar -zxf dahdi-linux-complete-current.tar.gz
tar -zxf asterisk-1.6.1-current.tar.gz
tar -zxf spandsp-0.0.6pre18.tgz
tar -zxf libpri-1.4-current.tar.gz
tar -zxf asterisk-addons-1.6.1-current.tar.gz

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

SpanDSP (optional)

cd /usr/src/asterisk/spandsp-0.0.6
make clean
./configure
make
make install
cat > /etc/ld.so.conf.d/spandsp.conf << EOF
/usr/local
/usr/local/lib
EOF
ldconfig -v

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, /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

Asterisk-addons

cd /usr/src/asterisk/asterisk-addons-VERSION

make clean
./configure
make menuselect

Choose what you do and don't want. Unless you really need oh323, deselect it as it can be the cause of compilation woes.

make
make install

Install sample files in /etc/asterisk

make samples

Edit /etc/asterisk/cdr_mysql.conf and add 'loguniqueid=yes' to the global section.

mISDN drivers for Digium B410P (optional)

Removed - have yet to test installation with DAHDI

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";

Configure various files

Set up CDR to MySQL

Edit /etc/asterisk/cdr_mysql.conf
[global]
hostname=localhost
dbname=asterisk
table=cdr
password=MYPASS
user=astrealtime
port=3306
sock=/var/lib/mysql/mysql.sock
userfield=1

Set up realtime

Edit res_mysql.conf
[general]
dbhost = localhost
dbname = asterisk
dbuser = astrealtime
dbpass = MYPASS
dbport = 3306
dbsock = /var/lib/mysql/mysql.sock

If you are using version 1.6.0 or lower

Edit /etc/asterisk/extconfig.conf
[settings]
queues => mysql,asterisk,queues
queue_members => mysql,asterisk,queue_members
sippeers => mysql,asterisk,sip
sipusers => mysql,asterisk,sip
voicemail => mysql,asterisk,voicemail_users

If you are using version 1.6.1 or higher

Edit /etc/asterisk/extconfig.conf
[settings]
queues => mysql,asterisk,queues
queue_members => mysql,asterisk,queue_members
sippeers => mysql,asterisk,sip
sipusers => mysql,asterisk,sip
voicemail => mysql,asterisk,voicemail_users

If mysql db resides on a different host than asterisk, you will want to use "general" for the database parameter, instead of "asterisk" in extconfig.conf

Note - You may see documentation stating that whatever is in the [] section of res_mysql.conf is to be used for the "database" field in these extconfig parameters. For example
queues => mysql,general,queues ... This seems to be false, at least in version 1.6.2.10, and you should in fact use the database name referenced in "dbname" in res_mysql.config

ODBC configuration (using settings from above)

/etc/odbcinst.ini

[MySQL]
Description = ODBC for MySQL
Driver = /usr/lib/libmyodbc3.so
;For x64 systems
;Driver = /usr/lib64/libmyodbc3.so
Setup = /usr/lib/libodbcmyS.so
FileUsage = 1
(Note the '3' which isn't in the original sample file!)

/etc/odbc.ini

; DSN definitions
[astrealtime]
Description = Asterisk realtime and other FUNC_ODBC access
Driver = MySQL
Socket = /var/lib/mysql/mysql.sock
Server = localhost
User = astrealtime
Pass = MYPASS
Database = asterisk
Option = 3

/etc/asterisk/res_odbc.conf

; Environment variables
[ENV]

; Connections
[astrealtime]
enabled => yes
dsn => astrealtime
username => astrealtime
password => MYPASS
pre-connect => yes
idlecheck => 3600

/etc/asterisk/func_odbc.conf

This really depends on why you need database access from the dialplan!

Setting up Asterisk on a vserver

Removed - have yet to test installation with DAHDIn

Troubleshooting:

If sip phones are not registering to asterisk and you receive 408 request timeout, you may need to alter iptables.
iptables -I RH-Firewall-1-INPUT -p udp --dport 5060 -j ACCEPT
iptables -I RH-Firewall-1-INPUT -p udp --dport 10000:20000 -j ACCEPT
service iptables save
