Once you have fixed the potential errors, simply click ‘Next’ to get to the database setup section.

Here, fill in the form with the values corresponding to your database. Click ‘Save’ then ‘Next’. Myddleware will then attempt to connect to your database.

WARNING: before submitting this form, please ensure you have already created an empty Myddleware database on your host server.

If Myddleware was able to connect to your database, it will have automatically updated it with the necessary schema and the following message will be displayed :

Simply click ‘Next’ again. Myddleware will now attempt to load the configuration data it needs to be able to run. The following message should then be displayed :

Once you’ve clicked ‘Next’ again, the fifth and final step to install Myddleware will be to create your Myddleware user :

1.6.Install via command

Before starting, make sure your configuration is correct : open a command shell from your myddleware subdirectory and run this command :

symfony check:requirements

Change your configuration until your system is ready to install Myddleware :


Create a .env.local file at the root of your myddleware subdirectory. This file will override the configuration defined in the .env file. Inside this file, add the following line :





Change the APP_SECRET to a random string of 32 characters  (more info here)

Create a database on your server and replace each value from the DATABASE_URL variable with your database connection parameters :

  • username : the username used to login to your database
  • password: the password associated with that username
  • host: your database host (if you installed Myddleware locally on your server, it will be ‘localhost’
  • port: your database port (usually 3306 or 3307 if localhost)
  • dbname: the name of your database

For example :






Then, go to your Myddleware directory and run these commands :

  • Connect to the database
php bin/console doctrine:schema:update --force
  • Load Myddleware fixtures :
php bin/console doctrine:fixtures:load --append
  • Create your Myddleware credentials
php bin/console myddleware:add-user

or if you want to have a ROLE_SUPER_ADMIN directly :

php bin/console myddleware:add-user --superadmin

You will be prompted to create your username, email & password. You can still add a role to your user after its creation with the command :

php bin/console myddleware:promote-user <email> ROLE_SUPER_ADMIN

2.Optional : changing Myddleware user privileges

Myddleware allows you to modify privileges for each of your users. To do so, you will need to open a terminal from your web server and access the myddleware folder by typing the following command:

cd myddleware

  • Adding Super Admin privileges 

Some advanced Myddleware features such as cancelling or deleting all documents from a rule are restricted to Super Admin users. To enable these privileges for a Myddleware user, once in the myddleware directory, type the following command :

php bin/console myddleware:promote-user

Type the user’s email address, press Enter then type ROLE_SUPER_ADMIN and press Enter again.

  • Demoting a user

If you wish to remove some special roles from a user privileges (such as ROLE_SUPER_ADMIN), use the following command :

php bin/console myddleware:demote-user

  • Add a new user

If you wish to add another Myddleware user, type the following command from your myddleware directory :

php bin/console myddleware:add-user

3.Setting up a cron task

Myddleware can work with background tasks to sync your data, send notifications, clean data, and more.

If you wish to do so, you will have to set up some background tasks using the crontab.

Before creating the crontask, make sure your configuration is correct, open a command shell and run this command :

php bin/symfony_requirements


Change your file permission or PHP configuration in case of permission error or missing PHP requirement :


You can now start the following tasks depending on your needs :

cd <myddleware directory>; php bin/console myddleware:synchro ALL  --env=background  > /dev/null 2>&1

  • This program will synchronise the data by running every active rule.
  • Parameter => ALL or rule_name_slug :

cd <myddleware directory>; php bin/console myddleware:rerunerror 100 5  --env=background  > /dev/null 2>&1

  • This program will read the documents in error and will try to send them again
  • 1st parameter => limitation on the number of documents in error that the program will read. In this particular case, the program will read a maximum of 100 documents in error
  • 2nd parameter => limitation on the number of attempts : documents that Myddleware tried to send maximum 5 times will be read.

cd <myddleware directory>; php bin/console myddleware:cleardata  --env=background  > /dev/null 2>&1

  • This program will clear all data depending on whether the parameter “Deleting data” is set on the rule.
  • Don’t run this program if you don’t want to clear data.

cd <myddleware directory>; php bin/console myddleware:notification  --env=background  > /dev/null 2>&1

  • This program will send a notification if some documents are in error. An e-mail will be sent to the email address set up in the file myddleware/app/config/config_background.yml , parameter notification_emailaddress

Here is an example of the crontab :


4.Upgrading Myddleware

We suggest you use git to update Myddleware. If you don’t have git on your server, here are the instructions on how to install it : https://git-scm.com/download/linux

Before doing anything else, create a backup of your Myddleware before updating.

After the backup, go to the root directory of Myddleware and run the command as stated below to update all the Myddleware files.

If you have never used git with Myddleware, please run these commands from your Myddleware root directory:

git init
git remote add -t master origin https://github.com/Myddleware/myddleware.git
git fetch
git checkout origin/master -ft

Then you can upgrade Myddleware with this command :

php bin/console myddleware:upgrade --env=background

If you have a problem during the upgrade you can do it step by step by following this tutorial :

git pull

If you get this message below during the pull, you have probably changed at least one file in the Myddleware standard code. Please read the good practices article to learn how to add custom upgraded & safe code in Myddleware. It will help you manage the conflicts. You can also delete these files, run the pull and you will get the latest version of this files. However, you will loose your custom code.

Then update Symfony vendors and their dependencies:

php composer.phar install --no-plugins

At this stage, if it is your first upgrade with git, you will have to answer “yes” several times to this question:

Then run this command to update Myddleware’s database:

php bin/console doctrine:schema:update --force --env=background
php bin/console doctrine:fixtures:load --append --env=background

Then, please change your myddleware version parameter “myd_version” into the file <myddleware>\app\config\parameters.yml using the version number in the file <myddleware>\app\config\parameters.yml.dist

Finally clear the cache and refresh css and js files with these commands:

rm -rf var/cache/*
php bin/console assetic:dump --env=background --no-debug
php bin/console assets:install web --env=background
