I have installed httpd, mysql, php on a centos machine. Php executes in the browser of my machines website, mysql can be ran from the command line, but mysql within php in a browser will not work.
I know my code is syntactically correct since it will run on another Centos Lamp machine and NetBeans says it is.
My code
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="refresh" content="300">
<title> Freeze Warn Points table Query"</title>
</head>
<body>
<?php
include("config.php");
echo $dbhost;
echo "<br />\n";
echo $dbuser;
echo "<br />\n";
echo $dbpasswd;
echo "<br />\n";
mysql_connect($dbhost, $dbuser, $dbpasswd) or die("Unable to connect to database");
echo 'Connected Successfully';
mysql_select_db($dbname);
echo "zone"." ";
echo "currentLow"." "."dateLastRep"." ";
echo "priority"." "."siteId"." &nbs p; "."siteName";
echo "<br />\n";
$result = $sql = 'SELECT zone, currentLow, dateLastRep, pri, siteId, siteName from points order by zone, pri';
$numRows = mysql_num_rows($result);
echo "Matches: ".mysql_num_rows($result);
for($a=0; $a<$numRows; $a++)
{ $rowArray = mysql_fetch_row($result);
echo $rowArray[0]." ".$rowArray[1]." ".$rowArray[2]." ".$rowArray[3]." ".$rowArray[4]."  ".$rowArray[5]."<br />";
}
mysql_close();
?>
</body>
</html>
When executed on the CENTOS lamp machine in question out puts this
"; $result=mysql_query("SELECT rpad(zone,6,'-'), rpad(currentLow,13,'-'), rpad(dateLastRep,13,'-'), rpad(pri,8,'-'), rpad(siteId,6,'-'), siteName from points order by zone, pri"); $numRows = mysql_num_rows($result); for($a=0; $a<$numRows; $a++) { $rowArray = mysql_fetch_row($result); echo $rowArray[0]." ".$rowArray[1]." ".$rowArray[2]." ".$rowArray[3]." ".$rowArray[4]." ".$rowArray[5]."
"; } mysql_close(); ?>
When I put the same code in the other machine, (it does not have the mysql database so it will not connect) displays this
204.227.112.31
apache
password
Unable to connect to database
httpd is running of course
mysqld is running
I have

Installed.
I checked the php.ini files and the httpd.conf files with the LAMP machine it works on and have been unable to find any discrepancies.
Unless I missed something.
Selinux is disabled.
I know it is not my code, but some type of setting somewhere on my machine, I have not been able to find.
I have been unable to find any thing like this issue.
Thanks,
Nancy

Hello everyone,
I just tried upgrading to Linux Mint 17 from version 16, and I obviously did something wrong since when I'm prompted for my password, I get an error message saying "failed to load session cinnamon."
Then there are some error logs which say failed to connect to virtual box kernel service for several lines, then below that "unable to find cinnamon-fullback-mount-helper."
I tried doing ctrl alt f2, but I get a whole bunch of gobbledy gook which I'm unable to copy and paste.
I also tried burning a new DVD-R with Mint 17, but my computer doesn't even read it when I power it on. Otherwise, I would have tried reinstalling the OS.
So any suggestions you have will be greatly appreciated.
Thanks.
hello Experts!
need some help here with python FTP. so what i'm trying to do is, from a linux machine, ill be sending over a python script to a windows machine via python ftp. that works fine with no problem. now, i want to execute that python script i sent remotely. im having trouble with that. here's my code to just execute the script:
p.s : please dont suggest other options such as python paramiko due to many network security reasons
Code:
ftp = ftplib.FTP("windows machine name")
ftp.login("username", "password")
ftp.cwd("where\\python\\script\\is kept\\")
ftp.sendcmd("python myscript.py")
but looks like it doesn't recognize that command. how do i accomplish this please?
After i've execute $ isql -v database dsn name command i get an error in form:"Floating point exception (core dumped)". My comp is Lenovo with 64b AMD processor and my OS is Ubuntu 15.04. As a noobie i suppose the error is in my libmyodbc.so driver. Any advice will be a ppreciated.

I tried to install bluegriffon. Didn't work with apt-get install (error: unable to locate package bluegriffon).
I installed compiler (with apt-get install build-essential)
then I unpacked the "bluegriffon-1.7.2.Ubuntu13.04.x86_64.tar.bz2" that I downloaded from their website
then I changed to bluegriffon folder with the unpacked files and I tried to compile the package but the "./configure command" did not work (error : -su: ./configu No such file or directory)
What should I do now?
