mysqli::real_connect(): (HY000/2002): Connection refused on Live

Question

I create a web site using PHP, Mysql, and Codeignater version 3. Then host it on iPage. When I upload on live I make changes in config file.

$db['default'] = array(
    'dsn'   => '',
    'hostname' => '66.96.147.118',
    'username' => 'bit_root',
    'password' => 'root',
    'database' => 'bit_shilp',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

I use codeignater version 3. On local it work great. But on live site It gives an error.

Please see this link http://bitshilp.com/BitShilp/index.php/home

It gives an error like this:

A PHP Error was encountered

Does bit_root privileges look like 'bit_root'@'%' ? – Widdershins

is parameters correct?? – Grouping

I hope for your own sake that your DB server at 66.96.147.118 (I assume you pasted the real address? You should never do that again for security reasons) does not accept MySQL connections on that external address. In most cases you need to connect to localhost or some other local address for the DB once your code is on the server. – Volute

Answer 1

If MySQL Server is up and running - then this looks like some transport (e.g. firewall) problem. First step is to try telnet command below - if it shows an error, then problem is not related to PHP or MySQL :

telnet 66.96.147.118 3306 

(On success it will print mysql version + some random characters)

Same problem occurd with me, with AWS RDS MySQL. Looked various sources, but as of this thread, almost all lack of answer. While this answer helped me, tweak in mind to update hostnames at server. Access your SSH and follow the steps:

cd /etc/
sudo nano hosts

Now, Appending here your hostnames: For example:

127.0.0.1 localhost
127.0.0.1 subdomain.domain.com [if cname redirected to endpoints]
127.0.0.1 xxxxxxxx.xxxx.xxxxx.rds.amazonaws.com [Endpoints]

and now, configuring config/database.php as follows:

$active_group = 'default';
$query_builder = TRUE;

$db['default'] = array(
    'dsn'   => '',
    'hostname' => '35.150.12.345',
    'username' => 'user-name-here',
    'password' => 'password-here',
    'database' => 'database-name-here',
    'dbdriver' => 'mysqli',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => TRUE,
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

where 35.150.12.345 is your IPv4 Public IP, located at ec2-dashboard > Network Interfaces > Description : RDSNetworkInterface >> IPv4 Public IP('35.150.12.345') there.

Note: Please note that only IPV4 will work at 'hostname' option. hostname, cname, domains will output database connection error.

You can check if mysql is running with:

mysql.server status

If its not then to start:

mysql.server start

Likewise to stop:

mysql.server stop

Answer 4

in Codeigniter change your 'hostname' => '35.150.12.345', to 'hostname' => 'localhost',

Answer 5

If this is a problem in the Fedora You have to start MariaDB every time just run

sudo systemctl start mariadb

Also keep in mind that every time you start, you have to start the Apache in the same way So run the following code each time before using the above code

sudo service httpd start

Answer 6

I am using Pop!_OS. After the recent OS upgrade to 21.4, it seems like MySQL packages got removed/missing automatically. Though mysql --version was showing that I have the MySQL available.

I've tried all other possible solutions, none of them worked. After installing MySQL again solved the issue for me. I've run the below command. Btw, I didn't lose any database.

 sudo apt-get install mariadb-server mariadb-client

Answer 8

According to the noonex's answer, I checked out my firewall with sudo ufw status verbose and it threw status: inactive so I executed sudo ufw enable, then it worked.
