WAMP: 'No such host is known' when trying to connect to mysql - mysql

Question

I got this error :
Warning: PDO::__construct() [<a href='pdo.--construct'>pdo.--construct</a>]: [2002] php_network_getaddresses: getaddrinfo failed: No such host is known. (trying to connect via tcp://1:3306) in Z:\work\...
My localhost/phpmyadmin works fine but I can't access localhost or 127.0.0.1 , I get a blank page with "Forbidden : You don't have permission to access / on this server."
I have nothing else running on my port 80
I modified my httpd.conf
DocumentRoot "z:/work/"
<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
</Directory>
<Directory "z:/work/">
Options Indexes FollowSymLinks
AllowOverride all
Order Deny,Allow
Deny from all
Allow from all
</Directory>
Also added in my httpd-vhosts.conf
<Directory C:/Users/Alex/Documents/GitHub>
Order Deny,Allow
Allow from all
AllowOverride All
</Directory>
<Directory Z:/work>
Order Deny,Allow
Allow from all
AllowOverride All
</Directory>
<VirtualHost *:80>
DocumentRoot "Z:\work\mysite"
ServerName bullseye.local
</VirtualHost>
<VirtualHost *:80>
DocumentRoot "C:\Users\Alex\Documents\GitHub\Myproject"
ServerName framework.local
</VirtualHost>
And my phpmyadmin.conf is as follow
Alias /phpmyadmin "c:/wamp/apps/phpmyadmin3.5.1/"
<Directory "c:/wamp/apps/phpmyadmin3.5.1/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Order Deny,Allow
Deny from all
Allow from all
</Directory>
The code giving the error :
$host = 'localhost';
$user = 'root';
$pass = '';
$database = 'mydatabase';
$this->db = new PDO('mysql:dbname=' . $database . ';host=' .$host . ';charset=utf8', $user, $pass);
I get the same error using mysql or msqli instead of PDO

My suggestion would be to:
Undo all your changes to httpd.conf. Your changes have removed all knowledge Apache has of the WAMP homepage i.e. localhost.
Comment out the include of the virtual hosts config and check you can again access the WAMP homepage.
Make sure that WAMP is 'OffLine', this will keep the C:\ drive and c:\wamp folder secure.
Now to your Virtual hosts definitions:
In order to keep the wamp homepage working the first entry should be as below, note the Directory block should be part of the definition of the VirtualHost and the security definition makes sure you can only access the wamp homepage from 127.0.0.1(localhost)
###must be first so the the wamp menu page loads
<VirtualHost *:80>
ServerAdmin webmaster#homemail.net
DocumentRoot "D:/wamp/www"
ServerName localhost
ServerAlias localhost
<Directory "D:/wamp/www">
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
</Directory>
</VirtualHost>
Each VHOST you define should contain its own security settings like this
<VirtualHost *:80>
DocumentRoot "Z:\work\mysite"
ServerName bullseye.local
ServerAlias bullseye.local
AllowOverride All
<Directory "Z:\work\mysite">
Order Allow,Deny
Allow from all
</Directory>
</VirtualHost>
<VirtualHost *:80>
DocumentRoot "C:\Users\Alex\Documents\GitHub\Myproject"
ServerName framework.local
ServerAlias www.framework.local
<Directory "C:\Users\Alex\Documents\GitHub\Myproject">
Order Allow,Deny
Allow from all
</Directory>
</VirtualHost>
Uncomment the Include in https.conf for your vhosts definitions and try accessing you other projects again.
I assume you have made the required changes to your c:\windows\system32\drivers\etc\hosts file to include a reference to all you virtual hosts? If not the hosts file should look like this :-
127.0.0.1 localhost
127.0.0.1 framework.local
127.0.0.1 bullseye.local

Answer 2

My concern is this:
DocumentRoot "z:/work/"
<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
</Directory>
<Directory "z:/work/">
Options Indexes FollowSymLinks
AllowOverride all
Order Deny,Allow
Deny from all
Allow from all
</Directory>
Unfortunately I don't have time to test this before I suggest it... but if DocumentRoot is z:/work/ then Directory / is also z:/work/ and you have set that to deny all and override none. Later trying to change the permission with Directory "z:/work/" would be considered an override and therefore not be applied? I suggest you try changing the AllowOverride to all or removing the deny all from / before you spend too much time hunting down other possible solutions.
