Warning: mysqli_connect(): (HY000/2002): Operation timed out in
/Applications/XAMPP/xamppfiles/htdocs/conn.php on line 4
Connection failed: Operation timed out
Get the following error while connecting to XAMPP on Mac OS X.
Code line is
$conn=mysqli_connect("SNA","root","","localhost");
// Check connection
if (mysqli_connect_errno()) {
echo "Connection failed: " . mysqli_connect_error();
}
Is it a Mysql Host problem or a Mysql default socket problem and how to resolve it? Default Host is 3306. I dont know where my mysql.sock file is generated and whether its generating or not.
change your code here, interchange host and database name
$conn=mysqli_connect("localhost","root","","SNA");
check php manual for more info : http://php.net/manual/en/function.mysqli-connect.php

I have a website that I should put on my domain.I have encountered an issue when I tried connecting to MySQL database so my code is not working. When I put
define("DB_HOST","http://domain");
define("DB_USER","user");
define("DB_PASS","password");
define("DB_NAME","dbName");
$connection = mysqli_connect(DB_HOST,DB_USER,DB_PASS,DB_NAME);
if(!$connection){
die();
}
mysqli_set_charset($connection,"utf8");
I get this error in log
Failed to connect to MySQL: Plugin http could not be loaded: /usr/lib64/mysql/plugin/http.so: cannot open shared object file: No such file or directory
otherwise, I tried to remove that HTTP and just use the domain as DB_HOST, but then I get error
define("DB_HOST","mydomain.com");
define("DB_USER","user");
define("DB_PASS","password");
define("DB_NAME","dbName");
$connection = mysqli_connect(DB_HOST,DB_USER,DB_PASS,DB_NAME);
if(!$connection){
die();
}
mysqli_set_charset($connection,"utf8");
PHP Warning: mysqli_connect(): (HY000/2002): Can't connect to MySQL server on 'domain.com' (115) in /home3/domain/public_html/a/i.php on line 7
Can anyone please help me find the solution to make this work?
Here's how I define a MYSQLI connection;
$con = mysqli_connect("localhost","username","password","database");
When you want to run an operation you just invoke the $con variable.
If you have issues check the permissions for the MYSQL user, they should at the very least include;
delete
insert
select
show view
update
I have just installed mysql onto my macbook pro, mysql seems to be working, however i cannot connect to mysql from php via mysqli. I keep getting errors. I have read many different articles and web pages, all of which seem complicated and not solving my issue.
I have added /tmp/mysock to the php.ini file:
pdo_mysql.default_socket= /tmp/mysql.sock
mysqli.default_socket = /tmp/mysql.sock
I have installed apache, php, mysql all separately and not using software such as MAMP, XAMP, phpmyadmin or MYSQLworkbench
This is my PHP code that is trying to connect to the database, and following the code is the error that is displayed at the browser.
<?php
$title = $_POST['blog_title'];
$body = $_POST['blog_entry'];
$link = mysqli_connect('localhost','root','password','blog');
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
mysqli_select_db($link,"blog") or die("Unable to select database");
$query = "INSERT INTO entires(title,body) VALUES ($title,$body);";
mysqli_query($query);
mysqli_close($link);
header('Location: ViewBlog.php');
exit();
?>
This is the error i get:
Error: Unable to connect to MySQL. Debugging errno: 2054 Debugging error: The server requested authentication method unknown to the client
Ive been trying to figure this out for so long, any help would be much appreciated, thanks.
The database i'm trying to access, i have already created in mysql ("blog");
Try checking the user auth type in MySQL.
I just ran into the same error while setting up wp on Win 10, PHP 7.3 and MySQL 8.0.13.
This was the full error message I was getting:
Warning: mysqli_connect(): The server requested authentication method
unknown to the client [caching_sha2_password] in
C:\inetpub\wwwroot\dbtest.php on line 2
Warning: mysqli_connect(): (HY000/2054): The server requested
authentication method unknown to the client in
C:\inetpub\wwwroot\dbtest.php on line 2 Error: Unable to connect to
MySQL. Debugging errno: 2054 Debugging error: The server requested
authentication method unknown to the client
To resolve the issue I had to set the MySQL user to use the standard authentication type.
Here is the SQL Script I ran to fix the issue:
ALTER USER 'user'#'localhost' IDENTIFIED WITH mysql_native_password BY 'pass';
This is my code for connecting to database:
$datbase=mysqli_connect("localhost:82","root"," ");
if(!$datbase)
{
die("connection failed".mysqli_connect_error());
}
it shows me that
Warning: mysqli_connect(): MySQL server has gone away in C:\Program Files\apache24\Apache24\htdocs\PhpProject3\php_DataBase.php on line 9
Warning: mysqli_connect(): Error while reading greeting packet. PID=10848 in C:\Program Files\apache24\Apache24\htdocs\PhpProject3\php_DataBase.php on line 9
Warning: mysqli_connect(): (HY000/2006): MySQL server has gone away in C:\Program Files\apache24\Apache24\htdocs\PhpProject3\php_DataBase.php on line 9
line number 9 is database=mysqli_connect("localhost:82","root"," ")
Error in this line and also remove space in password
$datbase=mysqli_connect("localhost:82","root"," ");
You are not connecting to MySQL, but to Apache server. If you didn't change MySQL port just use
$datbase=mysqli_connect("localhost","root","","databaseName");
Replace this line with
$datbase=mysqli_connect("localhost:82","root"," ");
with this one
$datbase=mysqli_connect("localhost","root","","your database name");
If your Mysql server is runs with default settings means . you don't need specify the port number . otherwise you need to specify port number as 5th parameter . like below Example .
Mysql default port number is 3306
$datbase=mysqli_connect("localhost","username","password","database_name","port_number");
if(!$datbase)
{
die("connection failed".mysqli_connect_error());
}
You should read first http://php.net/manual/en/function.mysqli-connect.php.
$link = mysqli_connect("host", "my_user", "my_password", "my_db");
Try this:
$datbase=mysqli_connect("localhost","root","","my_db");
if(!$datbase)
{
die("connection failed".mysqli_connect_error());
}
you are using port number on localhost that you are not set in php.ini file
try like this
//$datbase=mysqli_connect("localhost","username","password","databaseName");
$datbase=mysqli_connect("localhost","root","","databaseName");
I have an issue when I try to access my 1&1 database from the local web app I am coding.
Output: Failed to connect to MySQL: (2002) php_network_getaddresses: getaddrinfo failed: Unknown host.
I use mysqli (which works great with a local database) to connect my app with the DB and I already know the php5 issue with mysqli and 1&1 servers but this would occurs only if my app where on my server.
$mysqli = new mysqli("dbxxxxxxxxx.db.1and1.com", "dboxxxxxxxx", "xxxxxxx", "dbxxxxxxxx", 3306);
if ($mysqli->connect_errno)
{
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
else
{
$mysqli->set_charset("utf8");
}
Maybe the issue comes from the way I write the host, I tried to add "http://" before but the problem was the same.
Thanks for helping me! :)
Seems a name resolving problem. If you use Linux/MacOS, add the hostname and its IP address in hosts file:
# echo "123.123.123.123 dbxxxxxxxxx.db.1and1.com" >> /etc/hosts
You must replace this example IP for the real one.
I have some trouble connecting to a mysql server. I can connect using the linux terminal, so I know that my host, port, user, and password works. I cannot, however, connect using PHP.
PHP Version: 5.2.17
Server version: 5.5.27-log MySQL Community Server (GPL)
Here is a test code example:
<?php
$link = mysqli_connect('host.com:5306', 'user', 'pass', 'db');
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
if (!mysqli_query($link, "SET a=1")) {
printf("Errormessage: %s\n", mysqli_error($link));
}
/* close connection */
mysqli_close($link);
?>
Gives the following warning:
Warning: mysqli_connect() [function.mysqli-connect]: (HY000/2005): Unknown MySQL server host 'host.com:5306' (1) in /.../test.php on line 3
Connect failed: Unknown MySQL server host 'host.com:5306' (1)
Any ideas on what to do?
The port number must be a separate argument:
$link = mysqli_connect('host', 'user', 'pass', 'db', 5306);
Any ideas on what to do?
Sure. A simple three-step solution for any php function's problem:
Open your favorite browser
type php.net/ in the address bar followed by a problem function's name:
`php.net/mysqli_connect` in your case
Hit Enter
Now you have the function's description and can check the proper parameters list.
host is the IP of your mysql server, or maybe "localhost"
The host parameter in the mysql function need to be "localhost" or "127.0.0.1"
You set the parameter as "host:port" and that is your mistake. It's need to be the full alias of the network in the server or the remote server with the full IP address. You can found more information about this error here: http://compnetworking.about.com/od/workingwithipaddresses/g/127_0_0_1_def.htm
