Hello. I try to do my own dispatcher with redis db. I have problem with disconnecting
module wrom redis. Redis server is remote microsoft public server. This good solution for
many companies and it works stable
THe FIrst Isuue I saw when used
modparam("ndb_redis", "server",
"name=srv1;addr=non_local_serv;port=6379;db=4;pass=mypass")
[TOASTERISK]
redis_cmd("srv1", "EXISTS $si", "s");
xlog("L_INFO","ASTERISK with ip $si is {$redis(s=>value)}");
$var(setid)=0;
if ($redis(s=>value) == 0) {
xlog("L_INFO","Request {$rm} from $si != {$var(dest)} It means call
NOT from ASTRISK");
}
And when this call begins I get <null> s value. But If I EXISTS it from redis
comsole there is successfull reply.
Sometimes I see this at kamailio log
redisc_exec(): Redis error: Server closed the connection
I tried MONITOR redis from cli, but nothing happends when disconnect. (nothing means
-nothing at the cli)
So I tried one more thing:
I have some pools of requests
1. When options recieved to kam from asterisk
if (is_method("OPTIONS"))
{
if ($sp == 50600) {
redis_cmd("srv1", "AUTH mylonglongpass"","r")
redis_cmd("srv1", "SET $si $TS", "r");
redis_cmd("srv1", "EXPIRE $si 20", "r");
}
}
It works fine (Intresting that this works fine with the PASS through modparam key too)
Second pool when KAmailio choose ASTERISK to send INVITE from redis
#DISPATCHER_NEW
#$setid - is another var that gets from sql db.
$var(priority)=1;
redis_cmd("srv1", "AUTH mylonglongpass", "p");
while ($redis(b=>value) == 0)
{
xlog("L_INFO","{$rm} priority now is $var(priority) and setid
$var(setid)\n");
redis_cmd("srv1", "EXISTS $var(setid):$var(priority)",
"e");
xlog("L_INFO","ASTERISK with customer $var(setid) and priority
$var(priority) id {$redis(e=>value)} (if 1 - exists, 0 - not exisits)");
## Regis correctly get reply always
if ($redis(e=>value) == 1)
{
redis_cmd("srv1", "GET $var(setid):$var(priority)", "a");
#get IP of asterisk. Always get right value too
xlog("L_INFO","ASTERISK with customer $var(setid) and priority
$var(priority) is {$redis(a=>value)} (if 0 - not exisits)");
redis_cmd("srv1", "GET $redis(a=>value)", "b"); #check
timestamp that set at redis OPTION request
## There are I have truble when use AUTH command because redis return <null> after
GET. If i do GET from cli - all ok.
xlog("L_INFO","ASTERISK with customer $var(setid) and priority
$var(priority) have timestamp {$redis(b=>value)} (if null - no timestamp. This means it
down. Get new asterisk)");
if ($redis(b=>value) == 1){
$du="sip:"+$redis(a=>value)+":50600";
}
else{
$var(priority)=$var(priority)+1;
}
}
Offcource I checked all parameteres - database name and another connection attrs of
modparam
