Load Balancing

[ajitekno]

hi,

i have already a vicidial server up and running fine. i want to setup load balancing. I am wrtiting the process plz let me know if anything else i need to do.


Let us say you already have an Vicidial setup


prepare a server install all things and assume it

as your web and database server.

Copy all file .conf file of asterisk from 1

server and paste it to new server.

Take backup of databse from 1st server and delete

database.

restore database to this new database server.

In your 1st server change AST_SERVER-conf.pl

change database server ip.


remove these files from first server.

- AST_VDhopper.pl
- AST_cleanup_agent_log.pl
- ADMIN_adjust_GMTnow_on_leads.pl
- AST_DB_optimize.pl


2. The two servers need to be registered to each

other as IAX2 friends:
SERVER ONE(ASTtest1-10.10.10.15)
iax.conf:
register => ASTtest1:test@10.10.10.16

[ASTtest2]
type=friend
accountcode=IAXtrunk2
context=default
auth=plaintext
host=dynamic
permit=0.0.0.0/0.0.0.0
secret=test
qualify=yes

SERVER TWO(ASTtest2-10.10.10.16)
iax.conf:
register => ASTtest2:test@10.10.10.15

[ASTtest1]
type=friend
accountcode=IAXtrunk1
context=default
auth=plaintext
host=dynamic
permit=0.0.0.0/0.0.0.0
secret=test
qualify=yes


3. The two servers need to have wildcard

extensions assigned to the other server in the

dialplan:
SERVER ONE(ASTtest1-10.10.10.15)
extensions.conf:
[globals]
TRUNKIAX2=IAX2/ASTtest1:test@10.10.10.16

[default]
exten =>

_010*010*010*016*8600XXX,1,Dial(${TRUNKIAX2}/${EX

TEN:16},55,o)
exten =>

_010*010*010*016*8600XXX,2,Hangup

SERVER TWO(ASTtest2-10.10.10.16)
extensions.conf:
[globals]
TRUNKIAX1=IAX2/ASTtest2:test@10.10.10.15

[default]
exten =>

_010*010*010*015*8600XXX,1,Dial(${TRUNKIAX1}/${EX

TEN:16},55,o)
exten =>

_010*010*010*015*8600XXX,2,Hangup


4. For BOTH servers the VDAD extens need to be

setup there as well for the Load-Balance and

Load-Balance-Overflow AGI scripts, as well as

setting up the closer and inbound extens if

needed:

; VICIDIAL_auto_dialer transfer script

Load Balance Overflow:
exten =>

8367,1,AGI(call_log.agi,${EXTEN})
exten =>

8367,2,AGI(agi-VDAD_LO_transfer.agi,${EXTEN})
exten =>

8367,3,AGI(agi-VDAD_LO_transfer.agi,${EXTEN})
exten =>

8367,4,AGI(agi-VDAD_LO_transfer.agi,${EXTEN})
exten => 8367,5,Hangup

; VICIDIAL_auto_dialer transfer script

Load Balanced:
exten =>

8368,1,AGI(call_log.agi,${EXTEN})
exten =>

8368,2,AGI(agi-VDAD_LB_transfer.agi,${EXTEN})
exten =>

8368,3,AGI(agi-VDAD_LB_transfer.agi,${EXTEN})
exten =>

8368,4,AGI(agi-VDAD_LB_transfer.agi,${EXTEN})
exten => 8368,5,Hangup

; parameters for agi-VDAD_LB_closer.agi

(2 fields separated by five dashes "-----"):
; 1. the full extension formatted by

VICIDIAL for internal transfers * separated
; 2. the word START to denote the

beginning of the acceptance of the transfer
; inbound VICIDIAL transfer calls

5. Reload both Asterisk servers and for outbound

change the VDAD exten to 8367 or 8368 and kill

the AST_VDauto_dial.pl scripts on both servers so

they can restart and you can now look at the

AST_timeonVDADall.php page(per campaign

time-on-VDAD available from the STATS and REPORTS

link on the vicidial admin screen) that will allo

you to see the server_ip of the agent and the

server_ip of the call per campaign across all

campaigns.

Hi

You do not require anything else other than the

3 Servers, 1 for database and apache
2nd server for vicidial
3rd server for vicidial


Follow the Loadbalance.txt

your load balance setup is up and running


check 2 and 3rd servers are registered each other with IAX trunk

Note: make sure you replace the ip address according to your setup.

i want to setup on 2 servers only 1 for database and another for asterisk vicidial.


In this case should i install vicidial and asterisk on both servers. if yes , then what should i put in sip.conf extensions.conf . same config as first server?

Hi

you want to do only 2 servers

you need to install mysql+apache in one server

second server only Vicidial thats all.

just configure vicidial server as mentioned in the scratch_install and astconf point the database settings to mysql server ip address


ram

[angelos]

there is yet another way of doing it . Set everything up on one server.

Then install asterisk and the agi-scripts on the second server
and point the asterisk ip on the first server's astguiclient.conf file.

Warning , this will work for only a single asterisk setup, Not any more
but will allow you to have a cheap asterisk box

and remove some of the crontab entries.

[enjay]

If you have 2 servers and 1 is Asterisk/VICIDIAL and the other is Apache/MySQL then you are not load balancing anything. You are purely offloading the DB/WEB Processes to another server.

i think thats called multi server set up
