Adding a custom .so module doesn't seem to work

[michaelmillar]

I am trying to install MongoClient (the deprecated mongo.so not mongodb.so, but which I have working on my original system) in the devilbox container.

I followed the instructions here

so

cp /usr/lib/php/20131226/mongo.so /var/www/devilbox/mod/php-fpm-5.6/

and

cp /etc/php/5.6/mods-available/mongo.ini /var/www/devilbox/cfg/php-fpm-5.6/00-mongo.ini

But in the container I am still seeing MongoClient not found.

Otherwise, normally, I can do something like

sudo yum install openssl-devel php-devel
sudo yum groupinstall "Development tools" -y
sudo pecl install mongo
put extension=mongo.so in php.ini
restart httpd/apache

which works, except the restarting doesn't seem to be possible in the container.

Any ideas on how to proceed?

Container
PHP 5.6.33
MySQL 5.7
Apache 2.2
MongoDB (server) 2.8

Host
Ubuntu 16.04
Docker version 1.13.1, build 092cba3
docker-compose version 1.16.1, build 6d1ac21

Did you also adjust the path inside mongo.ini to actually point to the so inside the container?

[michaelmillar]

So according to this I add in cfg/php-fpm-5.6/00-mongo.ini

extension=/usr/lib64/php/custom-modules/mongo.so

When I run docker-compose up the log states

PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mongo.so' - libcrypto.so.1.1: cannot open shared object file: No such file or directory in Unknown on line 0

I also tried with

extension=/var/www/devilbox/mod/php-fpm-5.6/mongo.so

but there is the same result

The libcrytpo.so error has precedents, for example here, or here, but the files don't exist at the location the poster suggests copying from.

[cytopia]

Yes, looks like a library problem. Then you need to wait another 1-2 weeks until the new PHP Docker images will arrive

[cytopia]

This should fix your problem. Please let me know if it works (mongo.so already bundled now): #203

[michaelmillar]

I followed the three steps in #203

I also tweaked the .env file to make my app load, but only

1. php version 5.6
2. mysql 5.7
3. the locations of HOST_PATH_HTTPD_DATADIR and HOST_PATH_MYSQL_DATADIR
4. MYSQL_ROOT_PASSWORD

When I run docker compose up in the startup messages mongo exits:

Looks like official mongo container have some problems. I have tried mongo 2.8 and mongo 3.0, both crash. Mongo 3.2 works. Can you give it a shot.

[cytopia]

Looks like a mongodb problem. I have created an issue at their repository:
docker-library/mongo#251

[michaelmillar]

Yes the 3.2 container sets up without error on docker compose up

I still get Class MongoClient not found. in my app

[cytopia]

Then I was to quick closing this issue. So I will try to reproduce your error on my machine.

Can you tell me what framework you have used and how it is configured (just the base, not the custom part), so i can get it working locally

[michaelmillar]

It's Symfony.

The error arises from

   public function __construct($dbname, $dbhost) {

        if (!class_exists('MongoClient')) {
            throw new \Exception('Class MongoClient not found.');
        }

I'm not sure how to say how it is configured but I will edit this answer when I can find out better information on the error.

[cytopia]

It seems you are using a deprecated mongo library version: https://secure.php.net/manual/en/class.mongoclient.php

I try to see if this can be added anyway.

[cytopia]

Will be available after merge: devilbox/docker-php-fpm#5

[michaelmillar]

I think this is working now as I have not seen the same Class MongoClient not found. error.

I have some unrelated issues in the Symfony app, like JS not being run (presumably due to permissions errors) but I can try to work through those.

[cytopia]

Feel free to create a new ticket on your permission problems. I actually tried hard to make sure that especially permissions should never be an issue. Let's get this sorted.
