I have box1 (primary), box2, box3, and an arbiter, boxbal.
box1 also is the web server.
My connection string is:
mongodb://box1:27017,box2:27017
with the slaveOkay=true option
If box2 goes down, a php error is thrown and the site won't load.
What's the proper way to connect to the replica set to avoid this type
of failure?

If a machine goes down, you will probably get an exception thrown in
the PHP driver, which you should catch. Then you can retry and it
should work. What version are you using?

Cool, thank you. Should it be?
I also found https://groups.google.com/d/topic/mongodb-user/WwhOnk0aKE4/discussion , but I couldn't find clear direction or a best practice with regard to whether or not an arbiter should be in the list of hosts to connect to. http://www.mongodb.org/display/DOCS/Replica+Set+Internals#ReplicaSetInternals-NodeTypes seems to imply that it shouldn't be in the list.

No, it shouldn't. It won't cause any harm if you're not using
authentication. If you are using auth, arbiters don't hold any data
(including user info) so the driver won't be able to log in, wasting
time on connection.

Actually, it looks like this hasn't been fixed yet:

I don't have a solid repro, but while testing failover today I found
that including the arbiter in my connection string did cause harm to my
application (and I do not use MongoDB authentication). See
http://stackoverflow.com/questions/11125389/doctrine-odm-mongodb-not-retrying-queries
... after removing the arbiter from the connection string I did not see
"MongoCursorException: not master and slaveok=false" all day long in my
application log.

"I can not even get a connection to a SINGLE mongo db" caught my eye.
What happens if you run:
$m = new Mongo("mongodb://cache1-zone");
print_r($m->admin->command(array("ismaster" => 1)));

Thanks for the quick reply,
I commented out all my other code and ran your within the try catch and get the following.
Fatal error: Uncaught exception 'MongoConnectionException' with message 'Error 0' in /usr/local/apache2/htdocs/www/xxx/test-session.php:21 Stack trace: #0 /usr/local/apache2/htdocs/www/xxx/test-session.php(21): Mongo->__construct('mongodb://cache...') #1 {main} thrown in/usr/local/apache2/htdocs/www/xxx/test-session.php on line 21
I am here and can throw more code test at it if you need me too.

Sorry Kristina,
I forgot to mention there is no admin db in mongo,
not sure if its supposed to be there or not.
only local and some other little test ones.

Thanks, unfortunately, looks like your app's error handlers are
catching the error so I can't tell what it is from that. Can you run:
try {
$m = new Mongo("mongodb://cache1-zone");
}
catch (MongoException $e) {
echo $e->getMessage()."\n";
var_dump($e);
> > /usr/local/apache2/htdocs/www/xxx/test-session.php* on line *21*

Kristina,
I removed all my code and ran yours, getting the following result.
PHP CODE
try {
$m = new Mongo("mongodb://cache1-zone");
}
catch (MongoException $e) {
echo $e->getMessage()."\n";
var_dump($e);
}
$m = new Mongo("mongodb://cache1-zone");
}
catch (MongoException $e) {
echo $e->getMessage()."\n";
var_dump($e);
}
GIVES THE FOLLOWING OUTPUT

Are you using Drupal or some other framework? Do you have an error
handler set (http://www.php.net/manual/en/function.set-error-
handler.php)? Error 0 isn't getting generated by the driver.

No, there is no set_error_handler within the code.
The php.ini contains
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT

Also, can you:
1. ssh to you application server (where PHP is running).
2. Connect to cache1-zone via the mongo shell (run "mongo cache1-zone:
27017/test")
Make sure you're on the application server, not one of the mongod
server machines.

Forgot to mention this is 64 bit environment and pecl mongo driver loads as 64 bit to 64 bit apache. Nothing special.

Kristina,
Yes, the ssh works. I was able to ssh and connect to mongo primary cache1-zone.

Kristina,
As a side note I turned on logging to file on all 3 of my mongo nodes. I re-ran my php code and found that the arbitrator was receiving the connections and accepting them, but still the php returned error as before.
One thing I did to prevent arbiter from accepting these connections was to set its priority to 0 and turn on hide as follows.
cfg = rs.conf()
cfg.members[2].priority = 0
cfg.members[2].hidden = true
rs.reconfig(cfg)
The result was that connections from php logged the following on our primary node.
Fri Jun 22 20:26:50 [initandlisten] connection accepted from 172.16.1.20:46834 #121
Fri Jun 22 20:26:50 [conn121] end connection 172.16.1.20:46834
Fri Jun 22 20:26:50 [conn121] end connection 172.16.1.20:46834
The php code still returned the following:
Error 0 object(MongoConnectionException)#2 (7) { ["message":protected]=> string(7) "Error 0" ["string":"Exception":private]=> string(0) "" ["code":protected]=> int(0) ["file":protected]=> string(56) "/usr/local/apache2/htdocs/www/koalazone/test-session.php" ["line":protected]=> int(5) ["trace":"Exception":private]=> array(1) { [0]=> array(6) { ["file"]=> string(56) "/usr/local/apache2/htdocs/www/koalazone/test-session.php" ["line"]=> int(5) ["function"]=> string(11) "__construct" ["class"]=> string(5) "Mongo" ["type"]=> string(2) "->" ["args"]=> array(1) { [0]=> string(21) "mongodb://cache1-zone" } } } ["previous":"Exception":private]=> NULL }
This is a result of executing the following php code.
try {
$m = new Mongo("mongodb://cache1-zone");
}
catch (MongoException $e) {
echo $e->getMessage()."\n";
var_dump($e);
}
$m = new Mongo("mongodb://cache1-zone");
}
catch (MongoException $e) {
echo $e->getMessage()."\n";
var_dump($e);
}
Note:
if I run the following a connection is received by both primary and secondary each time php is issued.
//$m = new Mongo("mongodb://cache1-zone", array("replicaSet" => "koalacache"));
If I run the following then connection pooling is in play and the
//$m = new Mongo("mongodb://cache1-zone", array("replicaSet" => "koalacache", "persist" => 'sess' ));
ALSO, running the 2 statements above returns absolutely NOTHING from php error. But still I think I do not have a connection. Please instruct (provide official test code) as to how to query or insert a record so we can progress beyond this point.
I appreciate your help.

To test the connection, run the ismaster command (print_r($m->admin-
>command(array("ismaster" => 1)));). We should get one connection
working before you worry about a replica set connection. Also, the
"persist" option is only there for backwards compatibility, it doesn't
actually do anything.
The error you're getting is not generated by the PHP driver, so
something in your application must be intercepting it (maybe a default
exception handler?). As the driver seems to be connecting to MongoDB
(given the messages in your logs), it is difficult to know what is
going wrong without the error message.

Kristina,
I have still not been able to get a connection EVEN TO A SINGLE MONGO DB.
Using the latest php driver from pecl, and the latest mongo db binaries off your site. I am even using YOUR code to connect. I have made many posts here but still can not make a single connect. it keeps reporting CAN NOT DETERMINE MASTER.
I am going to have to abot my plans to use MongoDB without your focussed attention to making a simple connection work.

I also have no idea where the "Error 0" comes from, but it's the first

time that you are mentioning "Can not determine master". Is this
something you when you run the ismaster command on the shell, or when
you run it in PHP? That bit was a bit unclear in your reply.
cheers,
