Environment:
Apache 2.2.9
PHP 5.4.37
freetds 0.91
SQL Server 2008
After last night's round of updates applied from Microsoft my mssql_connect stopped working.
tsql -LH x.x.x.x still shows the server and port correctly
tsql -H x.x.x.x -U user connects fine
I get nothing in the apache log files or the freetds log
Here is the code segment that is failing (critical info changed)
error_reporting(E_ALL); ini_set('display_errors',1);
$con = mssql_connect('server', 'user', 'pass');
var_dump($con);
if (!$con) {
if ( function_exists('error_get_last') ) {
var_dump(error_get_last());
}
die('Could not connect to the server!!'.mssql_get_last_message());
}
And here is the result:
Warning: mssql_connect(): Unable to connect to server: server in /home/....../public_html/states/index.php on line 25
bool(false)array(4) { ["type"]=> int(2) ["message"]=> string(55) "mssql_connect(): Unable to connect to server: server"["file"]=> string(63) "/home/....../public_html/states/index.php"["line"]=> int(25) } Could not connect to the server!!
Please help!
I'm unable to post a comment to ask this, but here is my thoughts.
Obviously it's not connecting to the server outside of the command line, so you'll want to double check its configuration (check the server port, specify the port, etc..)
Is this running from a Win or Unix type OS?
It is Linux. I found a work around for the moment. The problem appears to be on the Windows side where, although a tsql -LH command shows the IP and port, it is not actually answering queries on the port. You get connected to the server via TCP and that is it.
Because the SQL server is multi-homed, I added a secondary connection to the web app server that connects to it over the primary IP.
I'll chase down the IP binding and service issue later. Or maybe just convert it all to mariaDB or Postgres.

I have Centos7 installation with nginx/php5.6. MS SQL 2008 R2 is working on another server.
MSSQL definitely has allowed tcp connection, custom (non domain) user, firewall disabled, and I can connect to it using HeidiSQL and that setting from another Windows machine.
I can telnet to MSSQL from Centos (and I see Log error "Length specified in network packet payload did not match number of bytes read; the connection has been closed. Please contact the vendor of the client library." with centos ip address in MSSQL logs, so no errors here).
I couldn't connect to mssql from centos using php_mssql or sqlcmd;
During sqlcmd:
Microsoft (R) SQL Server Command Line Tool
Version 13.1.0007.0 Linux
[root#***]# /opt/mssql-tools/bin/sqlcmd -S *** -U ***
Password:

During php interactive:
php > mssql_connect('***:***', '***','***');
PHP Warning: mssql_connect(): Unable to connect to server: *** in php shell code on line 1
I also tried tsql/freetds:
/etc/freetds.conf has section
[myserver]
host = ***
port = ***
client charset = UTF-8
tds version = 8.0 //also tried 7
[root#*]# tsql -S myserver -U ***
Password:
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
5 //begins to count, i could't understand what does it mean
Also tried to clean it all and install php7.0 with sqlsrv extension - the same problem;
There are some network strange - Centos serv and MSSQL are in different networks, I couldnt ping mssql from that server, but can telnet, i'm using ip, not the host name during connection attempts, so don't think it's a big deal.
Now I am out of ideas where to dig, any suggestions, please?
It was caused by misconfiguration in the network, I don't understand exactly how it is possible - to make telnet connection, but fail to connect normally, but our IT guys repaired this problem in less then half an hour.
This may be a duplicate question, however I searched internet for a while, and still couldn't find the solution.
I installed xampp on windows 7. The mysql is running on a random port. However, I can't access mysql from command line. I keep getting this error message:
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost'
(10061 "Unknown error").
I enabled mysql for windows services as administrator, and opened the port that the mysql is using through windows firewall settings. But the problem is still not fixed, and I still can not see the port from http://canyouseeme.org/.
Open a command line with administrative privileges. Type the command below.
netstat -a -p tcp | findstr ":138"
Give it the port number that your sql is using instead of ":138" in the above example. Check if the output contains 0.0.0.0 as the IP or not. If it contains your local area network IP then use that IP to connect. Perhaps MySQL is not using all IPs to listen for connections.
maybe your mysql service is not running.
my solution:
open the run and type 'services.msc'
find the mysql count that you build(note:not the mysql, is the mysql count that you build yourself),then run this service.
Find your Path that you are install xampp server on and open CMD Write that
"C:\xampp\mysql\bin\mysqld"
click Enter and Close , reopen CMd and write
mysql -u root

I am facing a weird problem here
we have a server A where the app files are stored
and B server with database
Tried to connect via command prompt from server A to B using the command
mysql -h xx.xx.xx.xx -u root -p password - and it worked
NOw i tried to create a php script in server A to connect to server B
the command is
$this->db=new PDO('mysql:host=xx.xx.xx.xx;dbname=databasename','root','password');
Connection failed: SQLSTATE[HY000] [2003] Can't connect to MySQL
server on 'xx.xx.xx.xx' (13) Fatal error: Uncaught exception
'Exception' with message 'SQLSTATE[HY000] [2003] Can't connect to
MySQL server on 'xx.xx.xx.xx' (13)'
Unable to find a solution on this.
Can any help on this?
thank you
I got it working by running a command in the database server :)
setsebool httpd_can_network_connect_db=1
thanks for the replies yycdev
Try specifying the port in your connection string and ensure the database server is set to allow remote connections and the port is open on your firewall (both of these I suspect are already done as you are able to connect via the terminal but it never hurts to verify and check things).
Change your PDO connection and add the port=3306 or if you're using MAMP use port 8889
$this->db=new PDO('mysql:host=xx.xx.xx.xx;port=3306;dbname=databasename','root','password');
Another thing to check is if – SELinux is blocking network connections. Login as root and run
setsebool -P httpd_can_network_connect=1
I don't know much about that, but try to place the port in back of the script:
$this->db=new PDO('mysql:host=xx.xx.xx.xx;dbname=databasename','root','password',3306);
I don't understand this the error,
Error: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
I am not familiar with drupal or any frameworks. Please advice me about this error and if I want to host my raw php site which I created in local WAMP server and connect to the database through, ...
#Database Connection
$dbc = mysqli_connect('localhost','****user', '***pw', '***db') OR die('Error: '.mysqli_connect_error());
what should I do?
Check whether mysql is running with the following command:
mysqladmin -u root -p status
And if not try changing your permission to mysql folder. If you are working locally, you can try:
sudo chmod -R 755 /var/lib/mysql/
Reference Connect to Server
I'm having a hard time getting my website connected to the mySQL database on host. However, when I was running my website on the PC by Apache it was connecting smoothly. The snippet I'm using to connect is:
<?php
$conn_error = 'Could not connect';
$mysql_host = 'localhost';
$mysql_user = 'root';
$mysql_pass = '';
$mysql_db = 'firstdatabase';
if(!mysql_connect($mysql_host,$mysql_user,$mysql_pass)|| !#mysql_select_db($mysql_db)){
die($conn_error);
}else{
//echo 'Connected';
}
?>
And it gives me the following error when I try to connect to mysql on the web host:
Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server
through socket 'MySQL' (2) in /home/umudo/public_html/connectserver.inc.php on line 10
I searched through the web for finding a solution but couldn't find any exact example of this.
Help: http://dev.mysql.com/doc/refman/5.0/en/connecting.html
Says:
On Unix, MySQL programs treat the host name localhost specially, in a
way that is likely different from what you expect compared to other
network-based programs. For connections to localhost, MySQL programs
attempt to connect to the local server by using a Unix socket file.
So you have to
use "127.0.0.1" instead of "localhost" to use tcpip instead of sockets, or
enable sockets in mysql server config (socket connections are probably disabled and that causes that error on linux)
Second method is better - using sockets for local connections is better than TCP/IP (better performance), but you may have no privileges to mysql configuration on that server.
Try installing phpmyadmin or php5-mysql as in apt-get install phpmyadmin.
