=======================================
You’re done with Asterisk installation here
Now lets get a2Billing for both asterisk server and Master SQL( just gonna use the sql for sql)
# cd /usr/src
# mkdir a2billing
# cd a2billing
Download the a2billing source from the link below ::
http://www.asterisk2billing.org/get-started/direct-download/
Click on download, it will download the source at your local computer and then upload it to your server using SFTP.
Once uploaded. extract it ::
tar -zxvf Star2Billing-a2billing-v1-current-0-g95789f5.tar.gz
cd Star2Billing-a2billing-d960375
then move all the files from Star2Billing-a2billing-d960375 to a2billing
#scp -r -p /usr/src/a2billing/Star2Billing-a2billing-d960375/ /usr/src/a2billing/
Extraction done. Then ::
>> On Master SQL Server do the following
# cd /usr/src/a2billing/DataBase/mysql-5.x
# mysql -u root -p < a2billing-createdb-user.sql;
# mysql -u root -p mya2billing < a2billing-mysql-schema-v1.7.0.sql;
We will need to make a new user on the master SQL server that has permissions remotely.
# mysql> CREATE USER ‘a2bMySQL’@’10.10.10.%’ IDENTIFIED BY ‘yourpassdb’;
# mysql> GRANT ALL ON *.* TO ‘a2bMySQL’@’10.10.10.%’;
Mysql database, user adding and importing the database file is restored.
Now Back to Asterisk Box
#cp /usr/src/a2billing/a2billing.conf /etc/
#nano /etc/a2billing.conf
>> Edit a2billing.conf to the following
===================================
[database]
hostname = 10.10.10.1
port = 3306
user = a2bMySQL
password = yourpassdb
dbname = mya2billing
dbtype = mysql
===================================
>> Edit the file as below ::
# /etc/asterisk/res_mysql.conf Or you can find /etc/asterisk/res_config_mysql.conf
# nano /etc/asterisk/res_mysql.conf Or nano /etc/asterisk/res_config_mysql.conf
===================================
[general]
dbhost = 10.10.10.1
dbname = mya2billing
dbuser = a2bMySQL
dbpass = yourpassdb
;dbport = 3306
dbsock = /var/lib/mysql/mysql.sock
===================================
>> Edit the file as below ::
# nano /etc/asterisk/extconfig.conf
===================================
[settings]
sipusers => mysql,mya2billing,cc_sip_buddies
iaxusers => mysql,mya2billing,cc_iax_buddies
sippeers => mysql,mya2billing,cc_sip_buddies
iaxpeers => mysql,mya2billing,cc_iax_buddies
===================================
>> Once done Fix folder Permissions using commands below ::
#chmod 777 /etc/asterisk
#touch /etc/asterisk/additional_a2billing_iax.conf
#touch /etc/asterisk/additional_a2billing_sip.conf
#echo \#include additional_a2billing_sip.conf >> /etc/asterisk/sip.conf
#echo \#include additional_a2billing_iax.conf >> /etc/asterisk/iax.conf
#chown -Rf apache /etc/asterisk/additional_a2billing_iax.conf
#chown -Rf apache /etc/asterisk/additional_a2billing_sip.conf
>> Copy sound to asterisk folder
#/usr/src/a2billing/addons/sounds/install_a2b_sounds.sh
>> Now Edit the Manger.conf
#nano /etc/asterisk/manager.conf
and add below code ::
==============================================
[myasterisk]
secret=mycode
read=system,call,log,verbose,command,agent,user
write=system,call,log,verbose,command,agent,user
==============================================
and now save and exit the file.
>> Copy AGI files and make executable
#cd /usr/src/a2billing/AGI
#cp a2billing.php /var/lib/asterisk/agi-bin/
#cp -Rf lib /var/lib/asterisk/agi-bin/
#chmod +x /var/lib/asterisk/agi-bin/a2billing.php
#mkdir /var/www/a2billing
#chown apache:apache /var/www/a2billing
#cp -rf /usr/src/a2billing/admin /var/www/a2billing
#cp -rf /usr/src/a2billing/agent /var/www/a2billing
#cp -rf /usr/src/a2billing/customer /var/www/a2billing
#cp -rf /usr/src/a2billing/common /var/www/a2billing
chmod 755 /var/www/a2billing/admin/templates_c
chmod 755 /var/www/a2billing/customer/templates_c
chmod 755 /var/www/a2billing/agent/templates_c
chown -Rf apache:apache /var/www/a2billing/admin/templates_c
chown -Rf apache:apache /var/www/a2billing/customer/templates_c
>> edit apache file that is /etc/httpd/conf/httpd.conf
#nano /etc/httpd/conf/httpd.conf
find DocumentRoot and chane to below:
===================
DocumentRoot “/var/www/a2billing”
===================
Save and exit the file and restart the apache.
# service httpd restart
Its Done.
Now you can go on your A2billing page using below link ::
http://yourip/admin/ Here (your ip will be your server ip )
log in Using the details below ::
======================
user: root
pass: changepassword
======================
Once logged in Change your login passowrd.
Now lets edit asterisk so the AGI works
# nano /etc/asterisk/extensions.conf
Paste below to the bottom of the file.
====================================
[a2billing]
; CallingCard application
exten => _X.,1,DeadAGI,a2billing.php
exten => _X.,2,Wait,2
exten => _X.,3,Hangup
[did]
; CallingCard application
exten => _X.,1,DeadAGI(a2billing.php|1|did)
Now configure httpd to start on boot
#ntsysv
arrow down to httpd and hit the space bar .tab to ok click enter
====================================
Asterisk will already start on boot
Errors and troubelshootings ::
Access Denied while changing the password.
Check the ownership of the /var/lib/php/session and change it to root.
#chown root.root /var/lib/php/session
