I have a PHP script that runs a .bat file on my windows machine using
$result = system("cmd /C nameOfBatchFile.bat");
This sets some environmental variables and is used to call Amazon EC2 API from the command line.
How do I do the same from a Linux server? I have renamed my .bat file to a shell (.sh) and changed the script to use 'export' when setting env vars. I have tested by running the code from a putty terminal and it does what it should. So I know the commands in the script are good. How do I run this from PHP? I have tried running the same command as above with the new filename and I don't get any errors, or file not found etc but it doesn't appear to work.
Where do I start trying to solve this?
---------------------------------- UPDATE -------------------------------
Here is the PHP script that calls the shell file -
function startAmazonInstance() {
$IPaddress = "1.2.3.4"
$resultBatTemp = system("/cmd /C ec2/ec2_commands.sh");
$resultBat = (string)$resultBatTemp;
$instanceId = substr($resultBat, 9, 10);
$thefile = "ec2/allocate_address_template.txt";
// Open the text file with the text to make the new shell file file
$openedfileTemp = fopen($thefile, "r");
contents = fread($openedfileTemp, filesize($thefile));
$towrite = $contents . "ec2-associate-address -i " . $instanceId . " " . $IPaddress;
$thefileSave = "ec2/allocate_address.sh";
$openedfile = fopen($thefileSave, "w");
fwrite($openedfile, $towrite);
fclose($openedfile);
fclose($openedfileTemp);
system("cmd /C ec2/mediaplug_allocate_address_bytemark.sh");
}
And here is the .sh file - ec2_commands.sh
#!/bin/bash
export EC2_PRIVATE_KEY=$HOME/.ec2/privateKey.pem
export EC2_CERT=$HOME/.ec2/Certificate.pem
export EC2_HOME=$HOME/.ec2/ec2-api-tools-1.3-51254
export PATH=$PATH:$EC2_HOME/bin
export JAVA_HOME=$HOME/libs/java/jre1.6.0_20
ec2-run-instances -K $HOME/.ec2/privateKey.pem -C $HOME/.ec2/Certificate.pem ami-###### -f $HOME/.ec2/aws.properties
I have been able to run this file from the command line so I know that the commands work ok. When I had this working on windows there would be a delay as the instance started up and I could echo the results to the screen. Now there is no delay as if nothing is happening.
