I download from https://github.com/luciddreamz/laravel Laravel for openshift
then upload over my repository over github. This code for connect to database not work.
The problem is that load variable from .env
file that locate in root of project
for solve this problem change.env
# local environment only
# for production, see .openshift/.env
APP_ENV=APPLICATION_ENV
APP_DEBUG=true

If someone is facing this issue in the hosting services like hostgator or any thing else then you should have to change the value of "localhost" to the relative values which is provided by the hosting provider. In my case it is available in the "phpmyadmin" tab of "cpanel" at the top right corner as "localhost:3302"
Check your DB_HOST
on your .env
file
DB_HOST=http://localhost/ --> DB_HOST=localhost
php artisan config:clear
it will help you, clear cached config
I'm using Laravel with Docker. I solved this problem by changing the value of DB_HOST
from localhost
to mysql
.
DB_HOST=mysql
If someone facing this problem when using Docker
, be sure if you are using your version of SQL.
In my case: MYSQL_VERSION=latest
changing to MYSQL_VERSION=5.7
.
Then you need to remove your unused Docker images with docker system prune -a
(docs).
Also, in your .env
you need to change DB_HOST=mysql
. And run php artisan config:clear
.
I think it will help someone.
In my case, when laravel generated the .env configuration file, laravel also generated two uncommented "DB_HOST" lines at line 11 and 12, delete the one that says "mysql" and uncomment (if yours it's commented) the other one (the one with the localhost ip 127.0.0.1) and it worked. (In my case).
Have a great day
If you are in a network with multiple docker containers, make sure they are all up and running! One of my containers was down, pretty obvious if you know where to check.
Another reason this can sometimes come up is due to a misconfiguration in your docker-compose (if you're using it) whereby the mysql container is not on the same network that your app servers are on.
If the network flag is forgotten or incorrect docker won't add the mysql to the DNS for the app server and therefore throw an error like this.
If you are on production server and the .env file doesn't work at all, go to /bootstrap/cache/config.php and on the line 230 more or less you will find the database data that is beeing cached from the .env file.
'mysql' =>
array (
'driver' => 'mysql',
'host' => '127.0.0.1',
'port' => '3306',
'database' => 'yorDBname',
'username' => 'YOURUSERNAME',
'password' => 'yourpass',
'unix_socket' => '',
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => 'InnoDB ROW_FORMAT=DYNAMIC',
),
It looks like you did not add a MySQL database to your application, OR you added it after you installed laravel. In that case, you need to stop & start (not restart) your application so that it will pick up your environment variables. (rhc app stop , rhc app start ). If you did not add a database yet, you will need to add one of the mysql cartridges, and then stop & start your application using the previously shown commands.
I was having the same problem and everyone was talking about this is related to DNS configuration, which make sense, since your container maybe isn't knowing how to resolve the name of the domain where your database is.
I guess your can configure that at the moment you start your container, but I think it's better to config this once and for all.
I'm using Windows 10 and in this case docker's gui give us some facilities.
Just right click on docker's icon in the tray bar and select "Settings" item.
Then, on the Docker's window, select the "Network" section and change the DNS option from "Automatic" to "Fixed" and hit "Apply". Docker will restart itself after that. I putted the Google's DNS (8.8.8.8) and it worked fine to me.
Hope it helps.
Just as on FYI to others suddenly experiencing this on an otherwise (previously) working Laravel installation:
My Laravel environment is on a Ubuntu VirtualBox hosted on a Win-10 laptop.
I used my phone to share Internet via USB and suddenly started experiencing this issue. I changed to using the phone as wireless hotspot and the issue went away. This is a nameserver/networking issue and is not specific to Laravel or MySQL.
In my case, everything was set up correctly, but my Docker
infrastructure needed more RAM. I'm using Docker for Mac, where default RAM was around 1 GB, and as MySQL uses around 1.5Gb of RAM ( and probably was crashing ??? ), changing the Docker RAM utilization level to 3-4 Gb solved the issue.
Please try this code:
npm install
In my case, it had absolute nothing to do with network issues.
I had been using my local laravel testing environment using laradock. Because laradock runs the mysql server in a different container, you have to set your mysql host in the .env file to the name of the docker mysql container, which by default is mysql.
When I switched back to using homestead, it was trying to connect to a host named mysql, when in fact is should be looking on localhost.
What a DUH moment!
We're using symfony with doctrine and we are in the process of automating deployment. I got this error when I simply hadn't provided the correct db creds in parameters.yml (I was running doctrine:migrations:migrate)
This thread has sent me on a bit of a wild goose chase, so I'm leaving this here so others might not have to.
First line of the error message describes the error type: "PDOException". The next line displays PDO::errorInfo
, i.e:
- SQLSTATE error code (a five characters alphanumeric identifier defined in the ANSI SQL standard).
- Driver-specific error code.
- Driver-specific error message.
The stack trace you attached, line 3, reveals that you did not specify the database connection parameters in the configuration file. The error show up when you test on local, right? You need to update /.env
with the actual database connection parameters.
If you are using Shopware with docker then you need to first run ./psh.phar ssh
then any bin/console
command will work
