On UBUNTU, I have a ruby app with a postgresql database on my localhost.
Everything was working fine yesterday, but today my database was gone. I was still able to open the app. Then I got an error saying something like,
run rails db:migrate
After I ran the command I started getting
PG::ConnectionBad at /
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
None of the config files were changed since yesterday.
I use docker-compose up to start the server and apparently it starts the connection but I still cannot access my localhost.
What could be the problem here?
Thank you in advance
Check the logs in your DB, if the DB is running on docker as well then maybe it's not finishing the DB boot correctly.
If this is the case, run the DB container manually first with the same options as in your docker-compose and then check docker logs for that container.

I'm using Laravel homestead and I'm writing a little artisan command line tool that I need to browse my site with javascript execution.
I run dusk test regularly with no difficulty, so I thought I would use Laravel's tools for this script.
I started out by running this early in my script:
\Laravel\Dusk\TestCase::startChromeDriver();
This started the driver fine running on port 9515 running as user vagrant (default homestead user)
But when I tried to access it (also from within the script) I would get an error:
Failed to connect to localhost port 9515: Connection refused
If I instead started it manually on the command line:
$ ./vendor/laravel/dusk/bin/chromedriver-linux --port=9515
The driver started fine again running on port 9515 as user vagrant, but this time my tool runs fine.
But I really want to be able to start the ChromeDriver from within the tool. So I also tried:
$process = new \Symfony\Component\Process\Process('./vendor/laravel/dusk/bin/chromedriver-linux --port=9515');
$process->start();
Connection was refused again.
Any idea why this works when I start it from the command line but not within my artisan command?
I can't explain why this makes a difference but it has. If I launch the driver with the full path:
/home/vagrant/Code/mysite/vendor/laravel/dusk/bin/chromedriver-linux --port=8888
all works fine now.
I'm currently developing a Spring Boot App with MariaDB as a Database. My localhost is a Windows 10 installation and the production server is a AWS Linux (first gen) image.
On localhost I have a local MariaDB installation.
On production I have a AWS RDS instance running MariaDB, default parameters.
Currently the problem I facing is the following, I'm trying to save the following characters ["↑", "↓", "→", "←"] to DB. On localhost characters are save as excepted. On the production server characters are saved as "?". Both DB's have the same mysqldump file.
I already debugged both Spring instances and they both receive parameters as intended.
Any ideas?
Extra 1:
The only big difference between both instance is that localhost runs with the ./mvnw command while the production site is a generated jar running inside a Docker container.
In utf8 (or utf8mb4), those characters are hex E28691 E28693 E28692 E28690
See "question mark" in Trouble with UTF-8 characters; what I see is not what I stored for an explanation of the step you failed to do.
In addition, check for ?useUnicode=yes&characterEncoding=UTF-8 in the getConnection() call.
I am trying to document my React Components and I am running styleguidist server along side with Laravel development server but the styleguidist server crashes with this error.
You have another server running at port 6060 somewhere, shut it down first
You can change the port using the `serverPort` option in your style guide config:
https://react-styleguidist.js.org/docs/configuration.html
I have configured the styleguidist server to run at port 6060 as to resolve this issue and succeeded to run the server only once. After that I am getting this issue again.
How can i resolve this??
The error is saying you have something else running at that port. Have you tried a different one? If you are running a UNIX system, you can see what is running on that port with:
lsof -i tcp:6060
I'm using homestead on windows 10 and installed laravel 5.4 when I'm trying to run dusk tests I get the following error:
1) Tests\Feature\ViewProductListingTest::user_can_view_product_listing
Facebook\WebDriver\Exception\WebDriverCurlException: Curl error thrown for http POST to /session with params: {"desiredCapabilities":{"browserName":"chrome","platform":"ANY"}}
Failed to connect to localhost port 9515: Connection refused
Has anybody had any luck getting around this?
Thanx.
I encountered this very problem today. I spent like 2 hours researching and finally resolved it by following the steps posted on this comment.
I ran the original basic test and it passed. I'll try to run more complex test and hopefully the solution still works.
It seems to me that the Homestead lacks some necessary software(Chrome, xvfb etc.) to run browser tests with Laravel Dusk. That's what that comment is trying to install.
Hope this helps!
I ran into this issue before and was not able to completely resolve it.
The connection refused error occured for me because the execution scripts for dusk in /vendor/laravel/dusk/bin were not set executable inside Homestead.
So i used a chmod 777 on those scripts.
After that it complained that if couldn't find an executable chrome binary, so i installed google-chrome in Homestead.
After I installed google chrome, the tests ran, but timed out before they could finish which i am researching now.
I ran into the same issue (but I'm on macOS Sierra). If you can, instead of running Dusk from the Homestead VM, run it from your host machine. Just make sure the DB_HOST value in your .env file is set to the hostname you use to access the site in your browser.
So for example, if you configured the Homestead site to be accessible at mycoolsite.app, use that as your DB_HOST value.
I know this is more of a workaround for situations where your host machine might be able to run it OK, but it's working for me at the moment if you can give it a try.
I downloaded 64-bit zipped version of mongodb for windows, created '/data/db' as instructed.
Now, when I run "mongod" command, I am getting the following error & the mongodb server shuts down automatically.
"ERROR : listen() failed error-10013. An attempt was made to access socket in a way forbidden by its access permissions. "
Please help me to clear the firewall settings in windows to prevent this error & run mongodb.
I was able to fix the error by using the following command : "mongod --bind_ip="127.0.0.1". :)
This error also seems to happen when mongod is already running. On Windows 10, mongod will be listed under Background Processes in the Task Manager if it is running. If it is already running, ending the task should allow you to run mongod again without this error occurring. Also check that it is not running as a service; it may be set to restart automatically.
Also, if you have a docker container running mongodb, you also get this error. If you stop your container(s) running mongodb, then it should start up.
I was able to fix this issue by allowing access for Mongo Db Server Application under firewall settings in my antivirus settings.
After you did the above step,open the cmd as administrator and go to the bin path of mongodb application in your system.
Then run the below command.
mongod
Note : try the above steps only after you tried the below steps
1) https://docs.mongodb.com/manual/tutorial/configure-windows-netsh-firewall/

I ran across a similar error which is why I ended up on this thread. For me, my solution was that McAfee Antivirus was blocking MongoDB.
The initial error basically showed that access was denied for mongo:
mongo error
I was able to do a search on the internet and found steps to allow MongoDB to run under McAfee Antivirus software by changing the setting for the app directly.
mcaffee settings
When I located MongoDB in the apps requesting internet access, it was initially set to blocked. I selected the app, clicked on edit and changed it to 'Designated ports'.
mongodb settings changed
Now, I am able to run mongo whether the mongod service is started automatically or if I start it manually in a hyper terminal window.
