I'm venturing out of the world of .NET and into the world of open-source. However, I've hit a few roadblocks while trying to get my development environment set up. And I'm kind of stuck on the most recent one.
I have installed: Apache 2.2, php 5.3.2, and mySQL 5.1.48
everything is working pretty much; apache is serving up PHP pages, and I'm able to create databases and tables in mySQL, however, I can't seem to get php to communicate correctly with mySQL. My php.ini has these lines un-commented:
extension=php_mysql.dll
extension=php_mysqli.dll
However, I keep getting this error message:
Warning: mysqli_connect(): (HY000/2002): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\mysql_test.php on line 15
any help would be greatly appreciated.
(btw, the php code runs properly when I put it on my web host)
This is most likely a configuration problem with the MySql server. It sounds like it either isn't listening on the correct port or something else is going on with the connection. You have the extensions loaded correctly because PHP is able to find the mysql functions. I would make sure you don't have a firewall blocking any of the requisite ports (actually, just try turning off your firewall and see what happens...just don't forget to turn it back on ;-) ). Also make sure if you are following a tutorial you didn't deviate from the MySQL setup instructions at all. If those don't work, post an update and we can try again.
This looks like bug #45150 : MySQL functions cannot be used with 5.3.x on Vista when using "localhost" -- I've had this problem once, and it took me some time to figure out what was causing it...
If you are working with Windows Vista (and possibly seven ?), and trying to connect to MySQL using "localhost" as host, try to replace that by the corresponding IP address : "127.0.0.1"
Or try to edit the hosts file, and to un-comment the line that corresponds to localhost in IPv4 :
127.0.0.1 localhost
(Remove the # at the beginning of the line)
Or to comment the line that corresponds to localhost in IPv6 :
#::1 localhost
(Add a # at the beginning of the line)
And here's an interesting article about that : PHP 5.3 and MySQL connectivity problem
Use XAMPP - it'll remove any headaches like this for local development.
XAMPP is a very easy to install Apache Distribution for Linux, Solaris, Windows and Mac OS X. The package includes the Apache web server, MySQL, PHP, Perl, a FTP server and phpMyAdmin.

I just set up XAMPP and, when I start the Apache localhost, it displays all of these errors when I search "localhost/phpmyadmin"
I am very new to this (just downloaded XAMPP) and I watched this tutorial: https://www.youtube.com/watch?v=hqfIksHKPPg on setting it up (I didn't install phpmyadmin since it was already installed with XAMPP)
I edited the notepad text files as stated in the video, but instead of a login, I get all of the error messages shown in the above picture...
I also opened config.inc.php and edited the line:
['Servers'][$i]['(MySQL root password)'] = '';$cfg
so it matched MySQL root password
Even if you have a suggestion to fix one of the errors, please still comment
Also, if you need any more information please let me know
You're getting several error messages because you have several problems :)
Cannot connect: invalid settings
Some setting is incorrect, most likely something in your config.inc.php is misspelled or incorrectly copied and pasted. Specifically, if the line ['Servers'][$i]['(MySQL root password)'] = '';$cfg is actually how it appears in your configuration, that is clearly the problem as the line should actually be $cfg['Servers'][$i]['password'] = 'green'; except with you password instead of 'green'...except that only applies if your auth_type is 'config', otherwise the 'password' line isn't used at all (since you're prompted for the password at log in). I'm not sure what XAMPP does here for auth_type, but I don't think you should have had to edit the configuration file at all, since you used the XAMPP installer which should have configured everything.
The server requested authentication method unknown to the client [sha256_password]
This appears to be a bit of a version mismatch in your installed files. Access denied after setting user's password with SHA256 in phpMyAdmin goes in to more detail, but this most often occurs when you've got MySQL 8 and PHP older than 7.4. Normally, I'd suggest upgrading your PHP version — but you're using the packaged XAMPP, which certainly wouldn't ship with conflicting MySQL and PHP versions, so something is odd here. Please confirm for us your MySQL and PHP versions. You didn't happen to have an existing MySQL or PHP installation before you installed XAMPP, did you?
Connection for controluser as defined in your configuration failed
This is probably related to the MySQL 8/PHP 7.4 conflict. There is an administrative user (called the controluser) that phpMyAdmin can use to manage some extra features, ordinarily you wouldn't need it to access phpMyAdmin (only to access those additional features), but it seems XAMPP has configured this for you. Since the authentication fails, you get an additional message that the controluser was not able to connect.
You could bypass this by commenting out the configuration lines referencing controluser and controlpass, although again the XAMPP package should have this all configured so I don't recommend that at this point.
The other messages are basically echoes of the previous messages; you get an additional protocol notification because the controluser is trying the same sha256 connection type that the main user was, and then finally phpMyAdmin is telling you that MySQL rejected the connection.
If this is a fresh XAMPP install, I'd suggest reinstalling, because something got a bit confused. I'd also suggest making sure that you don't have any other conflicting software running — XAMPP is a package of all the included parts, so you don't want to install or run your own Apache or MySQL instance which would interfere with the packaged kit.
For some unknown reason I cannot start WAMP server - The icon stays yellow no matter what:
Checked port 80, and it's not used.
No Skype, no Firewall.
Tried MANY solutions I suggested here in stackoverflow - absolutely nothing.
Tried to uninstall and reinstall - it worked for 10 minutes, then it didn't work again.
The only thing I'm changing is to include Virtual Hosts under httpd.conf. Checked every solution I could find on the net - nothing is working for me.
Maybe, just maybe it's because I previously installed PHP 5.5 apart from WAMP? If I go to PHP > PHP Extensions > then I can see there's a problem in php_opcache and php_enchant. When I click on them I get an error message that says: Could not execute menu item (internal error). [Execption] Could not perform service action: the service has not been started. The PHP Version I installed is 5.5.15. The PHP WAMP is 5.5.12... I don't have a clue how to uninstall PHP, and I couldn't find anything about that on the net.
PHP Error log says: PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_intl.dll' - %1 is not a valid Win32 application. in Unknown on line 0
EDIT - It seems like the cause for the problem is me trying to include Virtual Host via httpd.conf file. When I excluded, like in default, WAMP is online again. Any suggestion of how to include virtual host and still get WAMP get online?
It looks like you're running on a corrupt install have you tried reinstalling the software?
Alternatively i would recommend using Xampp which basically offers the same service as Wampp only with a bit more ease of access (also allowing for Mecury mail service and an FTP server for remote access).
The problem with php_intl can be corrected easily, see this answer
In order to find out what Apache is complaining about with the Virtual Hosts definition look at the Windows Event Log or, launch a command window and
cd \wamp\bin\apache\apachex.y.z\bin
httpd -t
This should give you filename and line number where your errors are.
Try changing that port number anyway. Mine stays yellow if the port number is set to 80, even though WAMP says it's not being used by any other program.
I'm trying to get a wordpress local install working on my Mac.
I've recently set up a database, username and password using the MySQL client as per the instructions in the wordpress codex. That part is ok.
When I go to the local site on my computer I'm prompted by wordpress to set up the wp-config.php file. Putting in the same details that definitely work with the MySQL client returns an error.
Manually updating these details in the 'wp-config-sample.php' file and renaming it as 'wp-config.php' also doesn't work - I'm now greeted with a big bold message: "Error establishing a database connection".
From what I can gather, php and mysql are not communicating with each other properly.
I've changed the apache 2 configuration file found in 'etc/apache2/httpd.conf' and uncommented the line which loads the php5 module: LoadModule php5_module libexec/apache2/libphp5.so
and restarted the apache server. This has still not fixed my problem. I'm stuck on what to do next... help appreciated please!
It's been fixed now.
php was looking in the wrong place for the mysql.sock file, and couldn't communicate with the mysql database, meaning wordpress couldn't be set up.
On the command line I typed
ps aux | grep mysql
to bring up as much info about mysql that I could. From this I saw that the mysql socket on my computer is being used at /tmp/mysql.sock
Meanwhile, in the "wp-config.php" file, I changed the line define('WP_DEBUG', false); to define('WP_DEBUG', true); and refreshed my web browser that was showing my localhost setup. This now said a lot more info than "Error establishing a database connection" - infact I could see that the mysql.sock was not configured correctly at all.
Creating a 'phpinfo.php' file with just the single line of code <?php phpinfo(); ?> was the pivotal turning point for me.
Putting that 'phpinfo.php' file in my localhost directory and then viewing it from my web browser not only definitely confirmed that the mysql.sock file was not configured properly, but it also showed where the configurations were being loaded from on my machine: '/private/etc/php.ini'
The next thing I did was open up the 'php.ini' file in a text editor and doing a quick find and replace to update the correct location of mysql.sock.
Finally, a restart of the local apache server needed to be done to fully update all the new settings that I'd been fiddling about with.
sudo apachectl restart
Now everything works fine!
The Error-Message "Error establishing a database connection" indicates clearly, that the php-script can not establish the connection. This can have one of the following reasons:
Your host in the wp-config.php is not correct.
The mysql-server does not listen on that host
The user you set up in the mysql has no privileges to connect the way you are trying
The firewall blocks the access of the php-script to your mysql-host
Try to connect the database with the same settings of your wordpress using Sequel Pro (or any other GUI to connect a mysql database). If the connection works, the problem 2. and 3. isn't your problem.
Look in your firewall-log to make sure 4. is also not your problem.
If all problems are excluded (even 1. after a final check), try to run something like phpMyAdmin to connect your database, to make sure your php-installation has the needed drivers.
can anyone solve this problem as per new to php
i have jsut installed wampsever 2.1 i am getting this error
my opertating system is windows 7 64 bit
phpmyadmin #2002 - the server is not responding (or the local mysql server's socket is not correctly configured)
The error message is pretty much self-explanatory: your MySQL configuration doesn't match that of php and/or phpmyadmin, or mysql isn't running.
You should do the following:
Make sure MySQL is running
Check phpinfo() for parameters of mysql extension
Check that config.inc.php in phpmyadmin has proper configuration directives
This is driving me nuts! I am getting the classic "Can't connect to local MySQL server through socket '/var/run/mysql4d/mysql4d.sock' (13)".
Everything I've dug up so far tells me my setup should be OK (eg, defining the sockets in php.ini and my.cnf, etc). Worse... phpmyadmin works with the same un/pw I am using in my own php. So obviously it's possible to connect, but I am screwing it up
I tried reverse-engineering the connection from phpmyadmin, but gave up it as too convoluted after a couple hours.
Can anyone offer some advice?
My configuration: Ubuntu 9.10 (Karmic), Apache 2.2, PHP 5.2.6, MySQL 4.1.22 (for legacy app reasons).
my.cnf (/var/lib/mysql4/my.cnf):
[client]
port = 3306
socket = /var/run/mysql4d/mysql4d.sock
[mysqld]
port = 3306
socket = /var/run/mysql4d/mysql4d.sock
php.ini (/etc/php5/apache2/php.ini):
[MySQL]
mysql.default_socket = /var/run/mysql4d/mysql4d.sock
[MySQLi]
mysql.default_socket = /var/run/mysql4d/mysql4d.sock
Same problem using mysql instead of mysqli, btw.
EDIT:
I should mention that I have installed mysql4 alongside the ubuntu default install of php & mysql for use with a legacy application and it is this installation that I am having trouble connecting with. I tried this:
ini_set('mysql.default_socket', '/var/run/mysql4d/mysql4d.sock');
and now the connection goes thru, but all queries return empty sets. (cries in frustration)
This sounds like a permission problem in /var/run/mysql4d/mysql4d.sock. What user are you running this as? Are the permissions o.k. on file system level?
If you Google for the error messages, you'll find a lot of people who had this and it was always a permission issue, sometimes due to an activated SELinux. Check this thread for a few possible solutions.
