I believe that I've successfully deployed my (very basic) site to fortrabbit, but as soon as I connect to SSH to run some commands (such as php artisan migrate or php artisan db:seed) I get an error message:
[PDOException]
SQLSTATE[HY000] [2002] No such file or directory
At some point the migration must have worked, because my tables are there - but this doesn't explain why it isn't working for me now.
One of simplest reasons for this error is that a MySQL server is not running. So verify that first. In case it's up, proceed to other recommendations:
Laravel 4: Change "host" in the app/config/database.php file from "localhost" to "127.0.0.1"
Laravel 5+: Change "DB_HOST" in the .env file from "localhost" to "127.0.0.1"
I had the exact same problem. None of the above solutions worked for me. I solved the problem by changing the "host" in the /app/config/database.php file from "localhost" to "127.0.0.1".
Not sure why "localhost" doesn't work by default but I found this answer in a similar question solved in a symfony2 post. https://stackoverflow.com/a/9251924
Update:
Some people have asked as to why this fix works so I have done a little bit of research into the topic. It seems as though they use different connection types as explained in this post https://stackoverflow.com/a/9715164
The issue that arose here is that "localhost" uses a UNIX socket and can not find the database in the standard directory. However "127.0.0.1" uses TCP (Transmission Control Protocol), which essentially means it runs through the "local internet" on your computer being much more reliable than the UNIX socket in this case.
The error message indicates that a MySQL connection via socket is tried (which is not supported).
In the context of Laravel (artisan), you probably want to use a different / the correct environment. Eg: php artisan migrate --env=production (or whatever environment). See here.
I got the same problem and I'm running Mac OS X 10.10 Yosemite. I have enabled the Apache Server and PHP that already comes with the OS. Then I just configured the mCrypt library to get started. After that when I was working with models and DB I got the error:
[PDOException]
SQLSTATE[HY000] [2002] No such file or directory
The reason I found is just because PHP and MySQL can't get connected themselves.
To get this problem fixed, I follow the next steps:
Open a terminal and connect to the mysql with:
mysql -u root -p
It will ask you for the related password. Then once you get the mysql promt type the next command:
mysql> show variables like '%sock%'
You will get something like this:
+-----------------------------------------+-----------------+
| Variable_name | Value |
+-----------------------------------------+-----------------+
| performance_schema_max_socket_classes | 10 |
| performance_schema_max_socket_instances | 322 |
| socket | /tmp/mysql.sock |
+-----------------------------------------+-----------------+
Keep the value of the last row:
/tmp/mysql.sock
In your laravel project folder, look for the database.php file there is where you configure the DB connection parameters. In the mysql section add the next line at the end:
'unix_socket' => '/tmp/mysql.sock'
You must have something like this:
'mysql' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'SchoolBoard',
'username' => 'root',
'password' => 'venturaa',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'unix_socket' => '/tmp/mysql.sock',
),
Now just save changes, and reload the page and it must work!
I encountered the [PDOException] SQLSTATE[HY000] [2002] No such file or directory error for a different reason. I had just finished building a brand new LAMP stack on Ubuntu 12.04 with Apache 2.4.7, PHP v5.5.10 and MySQL 5.6.16. I moved my sites back over and fired them up. But, I couldn't load my Laravel 4.2.x based site because of the [PDOException] above. So, I checked php -i | grep pdo and noticed this line:
pdo_mysql.default_socket => /tmp/mysql.sock => /tmp/mysql.sock
But, in my /etc/my.cnf the sock file is actually in /var/run/mysqld/mysqld.sock.
So, I opened up my php.ini and set the value for pdo_mysql.default_socket:
pdo_mysql.default_socket=/var/run/mysqld/mysqld.sock
Then, I restarted apache and checked php -i | grep pdo:
pdo_mysql.default_socket => /var/run/mysqld/mysqld.sock => /var/run/mysqld/mysqld.sock
That fixed it for me.
The answer from #stuyam solved the "No such file or directory" issue for me
Short answer: Change "host" in the /app/config/database.php file from "localhost" to "127.0.0.1"
But then I had a "Connection refused" error. If anyone had the same issue, my solution for this was to update the app/config/local/database.php file so the port is 8889:
'mysql' => array(
'driver' => 'mysql',
'host' => '127.0.0.1',
'port' => '8889',
'database' => 'databaseName',
'username' => 'root',
'password' => 'root',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
In my case i had no problem at all, just forgot to start the mysql service...
sudo service mysqld start
If you are using Laravel Homestead, make sure you're calling the commands on the server.
homestead ssh
Then simply cd to the right directory and fire your command there.
It worked after I change from DB_HOST=localhost to DB_HOST=127.0.0.1 at .env file
This is because PDO treats "localhost" host specially:
Note: Unix only: When the host name is set to "localhost", then the
connection to the server is made thru a domain socket. If PDO_MYSQL is
compiled against libmysqlclient then the location of the socket file
is at libmysqlclient's compiled in location. If PDO_MYSQL is compiled
against mysqlnd a default socket can be set thru the
pdo_mysql.default_socket setting.
(from http://php.net/manual/en/ref.pdo-mysql.connection.php)
Changing localhost to 127.0.0.1 will "force" the use of TCP.
Note: mysqli_connect is working fine with localhost.
Add mysql.sock path in database.php file like below example
'unix_socket' => '/Applications/MAMP/tmp/mysql/mysql.sock',
Eample
'mysql' => [
'driver' => 'mysql',
'unix_socket' => '/Applications/MAMP/tmp/mysql/mysql.sock',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '8889'),
Mamp user enable option Allow network access to MYSQL
Building on the answer from #dcarrith ...
Instead of editing the config files, I created an alias in the location that PHP is looking that connects to the real mysql.sock. (source)
Just run these two commands (no restart needed):
mkdir /var/mysql
ln -s /tmp/mysql.sock /var/mysql/mysql.sock
Step 1
Find the path to your unix_socket, to do that just run netstat -ln | grep mysql
You should get something like this
unix 2 [ ACC ] STREAM LISTENING 17397 /var/run/mysqld/mysqld.sock
Step 2
Take that and add it in your unix_socket param
'mysql' => array(
'driver' => 'mysql',
'host' => '67.25.71.187',
'database' => 'dbname',
'username' => 'username',
'password' => '***',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'unix_socket' => '/var/run/mysqld/mysqld.sock' <-----
),
),
Hope it helps !!
I'm running on MAMP Pro and had this similar problem when trying to migrate (create db tables). Tried a few of these mentioned suggestions as well but didn't do it for me.
So, simply (after an hour googling), I added two things to the /config/database.php.
'port' => '1234',
'unix_socket' => '/path/to/my/socket/mysqld.sock'
Works fine now!
Just i do one change in .env file
I have following line of code.
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=root
DB_PASSWORD=
Change host name localhost to 127.0.0.1
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=root
DB_PASSWORD=
That is work in my case because that can't find any hostname like localhost
And after changing hostname write following command
php artisan config:clear
php artisan migrate:install
php artisan migrate
I had this problems when I was running my application using docker containers.
The solution was put the name of the MySQL service container I was using in docker_compose.yml on DB_HOST. In my case, it was db :
DB_HOST=db
Hope it helps.
I ran into this problem when running PHPUnit in Elixir/Gulp, and Homestead as my Vagrant enviroment.
In my case I edited the .env file from DB_HOST=localhost to DB_HOST=192.168.10.10 where 192.168.10.10 is the IP of my Vagrant/Homestead host.
Check your port carefully . In my case it was 8889 and i am using 8888.
change "DB_HOST" from "localhost" to "127.0.0.1" and vice versa
I had similar problems accessing my Drupal website. I fixed it by opening the command line, and restarting my MySQL server or service:
service mysqld restart
This should work. If it doesn't, restart your local webserver:
service httpd restart
That should be enough. Hope it works for other environments, too. Note that these commands generally require superuser privileges.
I had the same problem using Docker and MySQL service name db in docker_compose.yml file:
I added the following in the .env file:
DB_HOST=db
you should also assure that your host is discoverable from the php app.
It was because PHP didn't figure out which host to use to connect.
I got the same problem in ubuntu 18.04 with nginx. By following the below steps my issue has been fixd:
First open terminal and enter into mysql CLI. To check mysql socket location I write the following command.
mysql> show variables like '%sock%'
I got something like the below :
+-----------------------------------------+-----------------------------+
| Variable_name | Value |
+-----------------------------------------+-----------------------------+
| mysqlx_socket | /var/run/mysqld/mysqlx.sock |
| performance_schema_max_socket_classes | 10 |
| performance_schema_max_socket_instances | -1 |
| socket | /var/run/mysqld/mysqld.sock |
+-----------------------------------------+-----------------------------+

In laravel project folder, look for the database.php file in the config folder. In the mysql section I modified unix_socket according to the above table.
'mysql' => array(
'driver' => 'mysql',
'host' => '127.0.0.1',
'database' => 'database_name',
'username' => 'username',
'password' => 'password',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'unix_socket' => '/var/run/mysqld/mysqld.sock',
),
Now just save changes, and reload the page and it worked.
As of Laravel 5 the database username and password goes in the .env file that exists in the project directory, e.g.
DB_HOST=127.0.0.1
DB_DATABASE=db1
DB_USERNAME=user1
DB_PASSWORD=pass1
As you can see these environment variables are overriding the 'forge' strings here so changing them has no effect:
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
More information is here https://mattstauffer.co/blog/laravel-5.0-environment-detection-and-environment-variables
solved
in my case it was a logic issue in code, the connection values are in a if statement:
if($_SERVER['HTTP_HOST'] == "localhost")
so the solution was to add a pipe and add 127.0.0.1, that solved the problem for me
if($_SERVER['HTTP_HOST'] == "localhost" || $_SERVER['HTTP_HOST'] == "127.0.0.1")
If you are using Laravel Homestead,
here is settings
(include Vagrant-Virtual Machine)
.bash-profile
alias vm="ssh vagrant#127.0.0.1 -p 2222"
database.php
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'database' => env('DB_DATABASE', 'homestead'),
'username' => env('DB_USERNAME', 'homestead'),
'password' => env('DB_PASSWORD', 'secret'),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
Terminal
vm
vagrant#homestead:~/Code/projectFolder php artisan migrate:install
Attempt to connect to localhost:
SQLSTATE[HY000] [2002] No such file or directory
Attempt to connect to 127.0.0.1:
SQLSTATE[HY000] [2002] Connection refused
OK, just comment / remove the following setting from my.cnf (on OS X 10.5: /opt/local/etc/mysqlxx/my.cnf) to obtain:
[mysqld]
# skip-networking
Of course, stop and start MySQL Server.
If anyone are still looking for the answer, just check your .env file. For some reason laravel create a .env.example file, so all this answers didn't work for me. I fixed my issue renamming .env.example to .env
This happened to me because MySQL wasn't running. MySQL was failing to start because I had a missing /usr/local/etc/my.cnf.d/ directory.
This was being required by my /usr/local/etc/my.cnf config file as a glob include (include /usr/local/etc/my.cnf.d/*.cnf).
Running mkdir /usr/local/etc/my.cnf.d, and then starting MySQL, fixed the issue.
In my case, I was running php artisan migrate on my mac terminal, when I needed to ssh into vagrant and run it from there. Hope that helps someone the headache.
In my case I had to remove the bootstrap/cache folder and try it again.
My cenario was after a server migration.
When using a VirtualMachine make sure you ssh into that machine and navigate to your App folder and call the php artisan migrate command from there.
I am experiencing the following scenario:
I want to split my database into separate read and write databases. For that reason i've setup the config/database.php
'mysql' => [
'driver' => 'mysql',
'write' => ['host' => env('DB_HOST_WRITE', 'localhost'),],
'read' => ['host' => env('DB_HOST_READ', 'localhost'),],
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
For DB_HOST_WRITE and DB_HOST_READ I've set the IP addresses for the servers where the databases are running on.
For DB_DATABASE, DB_USERNAME, DB_PASSWORD I've setup the database name and the login credentials.
Both servers are reachable, when I try to access them using mysql console commands like this: mysql -u USERNAME -h IPADDRESS -p
Here is the problem: When I attempt to run my migrations from a third server like this
php artisan migrate
But only the write database gets set up.
Is this the expected behaviour?
Do I have to migrate each database manually?
Is there a flag for the migration command, that allows me to specify the connection i want to migrate on?
I cant find anything about read write database migrations when I google for it.
There was no further database setup done. My information source is the following guide: https://laravel.com/docs/5.7/database#read-and-write-connections
Links to useful guides or solution suggestions are very welcome.
Thanks for your attention.
to #Travis Britz: Thanks for the hint. I was missing the term "MySQL Replication", what is not commented in the laravel documentations. I was mistakenly thinking laravel algorithms are handling the synchronisation on their own, what is in fact not happening.
Synchronization between databaseservers is handled by MySQL internal mechanisms
With these MySQL algorithms I was able to achieve a communication structure like that, what might be a common task in the deployment step of web applications:
I followed this guide by digital ocean to setup a mysql replication manually: https://www.digitalocean.com/community/tutorials/how-to-set-up-master-slave-replication-in-mysql
Digital Ocean is the server provider i'm hosting my applications at.

While trying to register, above (in the title) is the error that I get. The migrations were migrated successfully, so I don't think there is any connection problem with the database, but I don't know why this error is coming?
I have just tried to create an authentication system using
php artisan make:auth
And I have migrated the migrations
Please help...
don't mean to necro bump. I found this solution
https://laracasts.com/discuss/channels/eloquent/table-json-generates-an-error-when-running-migrations
Basically changing json to text in your migration files seems to work
tldr
"I believe the Json type in migrations was translated to text. Since 5.2 it's actually Json type now. Either way if your db doesn't support Json just use text instead of varchar or Json. It will still store Json."
You need to make some changes in the .env file:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravelfive(DB name)
DB_USERNAME=root (Username must be Root)
DB_PASSWORD='' (Password should be empty)
Then change the config -> database file like this:
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'laravelfive'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
Finally, run Xampp Apache and MySQL like in the following link:

I'm trying to get a crontab working for Cakephp (running on my shared Dreamhost server for now).
I have a shell set up as per the book, which works fine via either a cron run or manually executing (both via a shell file, e.g:
cron.sh
#########
cd /pathToApp/app/Console
/usr/local/bin/php cake.php updater list_reports
where updater is my shell and list_reports a method thereof.
The problem occurs when I try to access the database in the shell ("Using models in your shell", same link).
Error Message:
Error: Database connection "SQLSTATE[HY000] [2002] Can't connect to
local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)"

My DB Set-up (site works fine for http, do I need to add unix_socket or something?
array(

);
Thing I've tried:
Creating a symlink to /var/run/mysqld/mysqld.sock - permission denied
Can I even do this with shared hosting?
Tried various changes to the db settings above, no luck.
I note similar problems have been solved by people replacing localhost with 127.0.0.1, but I'm using a shared host, not local.
It's official! I'm a db!
I can confirm this problem was not caused by either Cakephp or Mysql, but rather for something I'd done myself and forgot about....
I had a little switch in database.php to automatically detect whether I was in the dev, test, staging environment etc. I had the default set to local, and since the bash script didn't pick up $_SERVER['SERVER_NAME'] which I was using for the switch, it defaulted to my local db.
Thanks to ifunk for spotting the clue which enabled me to unravel this and get back on track!

I am setting up Drupal 7.9 on my MAC OS X lion. I have it installed under MAMP/HTDOCS, copied default.settings.php to settings.php, changed the write permission for settings.php. I am trying to setup my database but keep running into the following error:
Failed to connect to your database server. The server reports the following message:
SQLSTATE[HY000] [2003] Can't connect to MySQL server on 'localhost/phpMyAdmin' (61).
I am able to access localhost/phpmyadmin very easily, the username, password and database have been specified. The database has been created at phpMyAdmin as well and the correct name is specified. This is leaving me pretty clueless as to what mistake I am making out here.
I haven't made any changes in the settings.php file, I am not sure what to do.
Any of you have a solution to this or have experienced a similar problem, that would be great!
Thanks much, Happy coding!!!
I think it's because you're setting your database server address as localhost/phpMyAdmin...it should just be localhost
Check you settings.php (located at sites/default). Look at line 180 the database settings should look like
$databases = array (
'default' =>
array (
'default' =>
array (
'database' => 'database_name',
'username' => 'user_name',
'password' => 'password',
'host' => 'localhost',
'port' => '',
'driver' => 'mysql',
'prefix' => '',
),
),
);
