Connecting to Vagrant [PuPHPet] MySql from host

Probably here with – I can’t connect to mysql on vagrant machine Yup I have been there

If you are php developer and are using vagrant you would want to use mysql tool to access the vagrant mysql server.

Here is the step by step procedure.

I will assume the PuPHPet configuration
First, get the user which can connect from any host

Log into your vagrant

vagrant ssh

Then open the mysql configuration file

vi /etc/mysql/my.cnf

And update the bind-address part to be This will allow address to be used from any host.
If you want to specifically access from some host only, then put IP over there.

Then being in your vagrant machine run

mysql -uroot -p123

This will be depending on if you have provided a password for root the default on puPHPet would ask password so you would have a password

After this allow root user to access everything from everywhere.. or you can create another user and grant that

mysql > GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123';

Then to make the sql pickup the changes made so far

sudo service mysql restart

Then being on your host machine open your sequel pro – if you are on mac.. or other clients you would use for mysql.

Mysql Host:
Mysql user: root
Mysql Password: 123

SSH Host:
SSH Username: vagrant – this is the default one
SSH key -> point the key in puphpet/files/dot/ssh/id_rsa
SSH Port: 2222 – this is also the default ssh port forwarding, if you change this change it here too..

Guest machine entered an invalid state Vagrant error

I used to use vagrant only at work place. But yesterday I upgraded my mountain lion to maverics and my php | ruby setting was jacked up.
I decided to use vagrant at my home as well and got this error.
It appears that I had an older version of Virtualbox and upgrading that helped the problem in no time.

Happy Vagranting

soft rlimits too low error on mongo

This is typical memory issue. Are you running a bunch of heavy programs along side? Check how much pages you are loading on chrome even.. and your IDE..

There is a way to add more before you start mongod though

ulimit -n 2000 && mongod

But I am a fan of using the resource effectively by removing apps that takes up my memory..

undefined symbol: php_json_encode in Unknown on line 0

Am fighting to install my application on Amazon EC2.. I installed the mongo and php mongo driver then restarted apache to get the above error message.
The problem is loading precedence. Mongo, which is dependent on, is being loaded ahead of the hence crying over ‘Where Is My ehiehiehi’
The fix would be to make sure we are loading json first before the mongo – actually this would be hte problem on while loading memcache as well..
On php.ini –
Right above the, add
Usually will be loaded through its own ini file json.ini
On Redhat Linux it would be inside


So, go to the json.ini and comment the line
restart httpd/apache and

react/zmq installation error on PHP 5.4 with composer

Last week I upgraded my PHP to 5.4 on my mac. It was not that bad, but I am starting to pay little by little.
I am using Ratchet for a websocket and for pushing I was using 0MQ.
My composer.json looks

        "cboden/Ratchet": "0.3.*",
		"react/zmq": "dev-master"

Then I do composer install, it was complaining zmq is not found in the system.
I had zmq already but it is on the php5.3 default directory. And I can’t use the file I compiled b/c i am using 5.4 now.
Here is the fix:
Go and grab the git clone from github

git clone git://

for further ways checkout this

cd php-zmq

Then do the following


Make sure you run the correct phpize in this case. If you are upgrading from 5.3 and still you have the old version sitting around on your machine, phphize will take the older one by default.
My new php 5.4’s one is in /opt/local/bin/phpize54. So make sure you are running the phpize with the new one.
One easy thing to do would be to symlink the old phpize with the new one like:

sudo ln -s new/phpize/path old/phpize/location/phpize

Backing to the topic,
Then do the configure, being inside the php-zmq folder, as follows

./configure --with-php-config=/opt/local/bin/php-config54

make sure to replace the value of –with-php-config with your proper php-config path

if you don’t have the packageconfig, you will have an error requesting for that and you can install it from macport – if you are using mac as follows:

sudo port install pkgconfig

Just search for pkgconfig for others distros you have and it should not be that difficult ..
once you do that install it by

make && make install

the compiled file should be inside the modules directory.
After this, copy that file into the php executables folder and add into your php.ini

Now you can do the composer install and it should install it..

Apache not executing PHP code – just renders the as it is

This is the issue when you are having a fresh install of apache usually.
You need to tell apache should handle the extensions so that it could process them accordingly.
On you apache path, go to the config and open the httpd.conf file
and add the following

AddType application/x-httpd-php .php

Also, make sure the Module for php is installed as well..
in your httpd.conf file, search for:

#LoadModule php5_module libexec/apache2/

and, of course, uncomment that to enable php.

Fatal error: require(): Failed opening required Hydrator in mongodb

I was working on putting POPO to MongoDB in symfony project.
I have the Document inside BundleDocumentMyDocument.php

I want to create this document for the first time, but would like to update the document if it exists based on its two fields like:
* I have taken out some of additional information and focus on the main code only..

$file_id = getTheFileId();
$accessor_id = getAccessorId();
			$file_access=$repository->findOneBy(array('fileId'=>$file_id, 'accessorId'=>$accessor_id));
			if ($file_access && $file_access instanceof FileAccess){
				$file_access=new FileAccess();

The problem I was facing was when I try to access the record, not when I was adding it.
and I know the record was there by using the command line mongo tool

The solution appears to be the missing config item for mongo:
on your config for mongo add

auto_generate_hydrator_classes: true

and that should fix the problem.

bundle does not contain any mapped documents/entities

This will be an error you would see when trying to generate entities or documents using:

app/console doctrine:mongodb:generate:documents YourPathToBundle

Actually the error would also suggest if you have mapping annotation error.

Mostly this could arise from mapping error as suggested.. check if you have @MongoDbDocument in the case of document or the respective @ORMEntity that would tell what that Plain Old Php Object is representing..
btw, the MongoDb and ORM are the aliases, so it could different on your setting..
