missing mysql extension for PHP?

[FezVrasta]

I'm trying to use your image to run a container which runs nginx and php, which connects to the official mysql container.

When I try to start my Joomla application, tho, it says:

Error displaying the error page: Application Instantiation Error: Could not connect to MySQL.

After some digging, I've found that the MySQL extension is not loaded in PHP.

I've then mounted /etc/php.d and used it to load a custom ini file with inside:

extension=/usr/lib64/php/modules/mysql.so
extension=/usr/lib64/php/modules/mysqli.so

(I've also tried writing just mysql.so without the full path)

But nothing seems to load...

Any clue?

HI, I'm using this image for my Cacti server and Mysql database and all seems to work ok. Can you attach information how you run both containers? Mysql setup and nginx-php

[FezVrasta]

I'm using Docker Cloud.

I've started the mysql container specifying the root password. The nginx-php contains starts specifying just the www/default path and adding a basic default.conf to serve files from there.

I've then put a test.php file which tries to connect to mysql and it doesn't work. Same with Joomla.

I try to connect to mysql host, with root as user and mysql as database.

Using another imge (nginx-docker) everything works fine, but I'd like to use this one because it's easier to configure.

are those containers linked?

Remember that docker-compose.yml for docker cloud differs in few options.

As far as I remember links: works a bit different.

See example of this docker-compose.yml

PS. If possible attach your cloud-config.yml

[FezVrasta]

Yes they are linked, if I ssh in the container and do ping mysql I get a reply... Also, configuring the same way the other php/nginx container, everything works.

Also, when I read the phpinfo(), there not seem to be any extension loaded.

No idea where to find cloud-config.yml sorry :(

[pozgo]

sorry, I mean docker-dompose.yml I need more details to diagnose it.

[FezVrasta]

Sorry I can't find where to get such file from the Docker Cloud UI...

Here some details, I hope they can be useful:

You are using a yml file to deploy into docker-cloud. That's where you set up everything. I would need to see how exactly you are deploying both database and Nginx.

[FezVrasta]

I'm not using any yml, I'm creating the services manually using the UI...

MariaDB was added to the image some time ago. Closing
