如何使ZF2 db凭据环境特定

Question

I am starting a new project.

I am using ZF2. I have just installed it and have the Skeleton application up and running.

This is my deployment process:

• I develop on my local machine
• I then push to my public github repository
• I then use deployhq.com to deploy those to my production server which is where the user would see the changes made.

I have tried to look around stack, zend site, and google at blogs etc but still dont have any real understanding or solution to my problem.

I want the application to use different database credentials based on its environment. E.g. if on 'dev', my local machine, then use credentials A, but if on live server, then use credentials B.

I have read a lot about global and local autoload config files etc, but baring in mind my github repo is public, any where I commit any config files with my db details would be visible.

I was wondering if there was a way to have, the same theory, global and local files with the DB connections in, i upload the production details manually, not via git for security reason, and tell git to ignore the local config file somehow? I would also need to know how I tell the application to use those config files based on the environment and there location.

In Zend 2 There are

1. Global configuration file &
2. Module level configuration file

IF you want to know there use you can refer the link below

How does configuration works in ZF2

When I had a same scenario I used the above link to understand and exploit Zend Config module which is really good to handle the situation like this .

create two files

production.php local.php

in both these files

return this array based on the environment

return array(
     "dbname" => "yourdbname"
     "dbhostname" => "dbhostname"
     "dbusername" => "yourdbusername",
     "dbpassword" => "yourdbpassword"
 );

in config/autoload/ directory of your zend framewrok application

later edit your config/application.config.php file as per below instructions

// get the application env from Apache vhost file ( here you can set in your apache vhost file as production or local )

$applicationEnv = getenv('APPLICATION_ENV');

$environmentSpecificConfigPath = "config/autoload/{,*.}{".$applicationEnv.",local}.php";

// Next with in the config array pass the environment specific configuration path

 'config_glob_paths' => array($environmentSpecificConfigPath)

in any controller or action

you can just use the below code

 $configArray = $this->getGlobalConfig(); 

Now $configarray has all your DB credentials to create a connection

$adapter = new Zend\Db\Adapter\Adapter(array(
    'driver' => 'Mysqli',
    'database' => $configArray['dbname'],
    'username' => $configArray['dbusername'],
    'password' => $configArray['dbpassword']
 ));

If you use config array to connect the DB in your entire application you dont need to worry about environment changes just make sure you have an Apache APPLICATION_ENV entry in your vhost file

you can do that by adding below line in your apache vhost file

 SetEnv APPLICATION_ENV "production" // in your production server 

 SetEnv APPLICATION_ENV "local"  // in your local 

Also Last but not least you can use the Zend Experts module ZeDB

To manage your CRUD applications

Hope the above steps may help you in creating the environment
