Currently I have a shell script within my application that depending on what argument you pass it, it will log you into either the live or development MySQL database shell. It works fine, no problem there.
The issue/challenge I am having is that if in the case my MySQL credentials (host / port) change for either the live or development database then I will manually have to edit this shell script, updating it will the new arguments. Problem is, I have done this before but I never want to have to do it again.
What I would like to do is have a PHP script (mysql.sh.php) that when executed, depending on the argument passed to it will log you into either the live or development database shell. How it will differ from the shell script is that it will pull the current credentials (and even host and port) from a PHP configuration class and pass those as arguments to a shell command that will log into the respective database.
Below gives you an illustration of what I am attempting.
#!/usr/bin/php
<?php
include ('common.php');
//Pull info from PHP class right here
exec("mysql --host={$myhostnotyours} --user={$myusernotyours} -p{$mypassnotyours} {$thedatabase}");
What I expect or would like is
mysl>
However, the command just hangs and I am not presented with the MySQL shell.
I would like to know if there is a way to accomplish what I am trying.
Thanks!

I want to call php using vba or vbs. The php file is stored on a server.
I am able to do it if the php file is stored locally:
Sub asasdsad
Call Shell("C:\xampp\php\php.exe C:\path\file.php", 1)
End Sub
This calls the php which executes a code for me. My problem is, the .php file I want to call is stored on a server, for which I've got username and password of course. Copying file to local directory is not an option as it's got a lot of includes.
My idea is to use PuTTY to connect to the server, and use it to execute above command, all from cmd using vba/vbs.
UserName = "un"
Passwrd = "pw"
'this would need additional parameters at the end to call php.exe like above
Call Shell("""C:\Program Files (x86)\PuTTY\putty.exe"" " & "-ssh " & UserName & "#ip address -pw " & Passwrd, 1)
As you can imagine there will be a lot of parameters so it just get complicated, not ever sure if this would work. I've never used PuTTY and all of this is quite new to me. I'm sure there's a better way?
First, do not use PuTTY, use Plink (PuTTY connection tool). It's a console application designed for automation (contrary to PuTTY, what is GUI application, designed for an interactive use).
Plink (again contrary to PuTTY) can accept a command to be executed on its command-line (it has a similar command-line syntax as OpenSSH ssh):
"C:\...\plink.exe" -ssh username#ip_address -pw password /path/to/php /path/to/script.php
So, i have a script that calls 2 other scripts that back up devices.
Problem is, If i call the main script manually that opens up the other two in a screen session, everything works fine.
The 2 scripts it calls basically sends data to an sql server via a php script.
IE
I have the line
$link = mysql_connect("server ip", "username", "password", "database");
Running manually (Which runs from my user directory) it works fine.
If i have the cron job run, it will run fine to a point when it gets to the php section of the script it gets the error
PHP Fatal error: Call to undefined function mysql_connect() in /export/home/myname/my_Scripts/php_script_its_running
So, being that it works correctly if i manually run it, and not when i run it via cron, I am assuming it is either running a different php instance due to it being run by cron or something oddball like that? or, idk, not 100% familiar with cron jobs yet.
So while i was debugging it more, it looks to be using a different version of php than what my user account is using, 5.1 comparred to 5.4
Not sure if there is an easy way to change it to use my user accounts php setup? Unfortunately i have no root access to the box.

So, i ran a working script, and added phpinfo(), grabbed the path information and added that to the cronjob so it would overwrite the defaults.
so the top of the cronjob file looks something like
SHELL=/bin/bash
PATH = /usr/kerberos/bin:/app/php-5.4.3/bin

I have a Python (2.7) script that connect to a remote device through SSH and configure it.
This script works fine when I run it.
I have a PHP page that execute other Python scripts and they are also working fine.
The problem: the SSH script doesn't work when I'm running it from the PHP page.
(there is no problem with the PHP page nor the Python script)
To be more specific, the script (when executed by PHP) is running until it gets to the first SSH related code (import paramiko).
How can it be, and is there anything I can do to make it work?
Thanks!
(OS: windows XP. Server:Wamp (Apachi http server)
for example, consider this simple code:
fp=open("file.txt","w")
fp.write("text")
import paramiko
fp.write("another text")
fp.close()
if executed by me, everything works fine. If by the PHP page- only the code until "import paramiko" is executed.
or:
fp=open("file.txt","w")
fp.close()
import paramiko
fp2=open("file2.txt","w")
fp2.close()
Executed by me- both files created. by php- only the first.
Moreover: I tried using Try & Catch but nothing comes up. No exception is thrown.
My guess is that paramiko is not in your PYTHONPATH environmental variable for the Apache user.
When Apache fires up PHP, it is calling PHP as the whatever the "Apache" user happens to be (in Linux normally apache (or httpd) user in group www-data). Sometimes this user will have different environment variables set than the ones that users normally have. While this generally doesn't matter, sometimes it will cause bizarre interactions (and I can see it happening with Pip).
I would add a try... except around paramiko:
try:
import paramiko
except Exception as e:
# log your exception here.
pass # I put this here so the example can compile.
#rest of the script
That should let you know whether or not it is installed (and I suspect it isn't).
I'm brand new to ruby and Watir, here's my issue...
I have a MySQL DB with test data that I need. I've done a lot in the past with this data and so I have a whole library of PHP tools for accessing this data, marking data as in use/used/bad/etc, and in general I have a lot of time invested in the PHP framework. So I'd really like to use the PHP framework as a wrapper around the Watir script - for example, use PHP to grab test user login data from the DB and pass it to the ruby script for processing.
I now have sites with javascript that need work/testing and PHP & cURL can't deal with this. So I'm working with Watir-WebDriver on Ubuntu 10.10 (Maverick, Desktop not Server) for these sites. The problem I'm having is with the use of PHP's shell_exec of the ruby script with all the Watir code.
The PHP shell_exec is executing the file - I can see it because I have some puts lines in the file which are being displayed. However, the code appears to be failing on the line
ff = Watir::Browser.new :firefox
I'm not getting an error from PHP.
The PHP line is:
echo shell_exec('ruby /var/www/watir_test.rb');
The ruby script works fine when I call it from a terminal window with the line:
ruby /var/www/watir_test.rb
I originally expected this was a permissions issue since it worked from the command line but not from a browser. However, since it can call the file well enough to return the hardcoded data I've provided for the test then ruby file permissions don't seem to be the issue. Could there be a permissions issue with opening a Firefox window from the www-data user?
When I run
ruby -d -v /var/www/watir_test.rb
I get:
{:extension=>:webdriver} {"app.update.enabled"=>"false"} {"browser.link.open_newwindow"=>"2"} {"browser.shell.checkDefaultBrowser"=>"false"} {"extensions.update.enabled"=>"false"} {"security.warn_entering_secure.show_once"=>"false"} {"webdriver_assume_untrusted_issuer"=>true} {"startup.homepage_welcome_url"=>"\"about:blank\""} {"browser.tabs.warnOnClose"=>"false"} {"extensions.update.notifyUser"=>"false"} {"toolkit.networkmanager.disable"=>"true"} {"security.warn_entering_weak.show_once"=>"false"} {"webdriver_firefox_port"=>"7055"} {"browser.download.manager.showWhenStarting"=>"false"} {"extensions.logging.enabled"=>"true"} {"network.manage-offline-status"=>"false"} {"network.http.max-connections-per-server"=>"10"} {"security.warn_submit_insecure"=>"false"} {"security.warn_entering_weak"=>"false"} {"security.warn_leaving_secure"=>"false"} {"prompts.tab_modal.enabled"=>"false"} {"security.warn_viewing_mixed.show_once"=>"false"} {"dom.max_script_run_time"=>"30"} {"webdriver_accept_untrusted_certs"=>true} {"browser.safebrowsing.enabled"=>"false"} {"security.warn_leaving_secure.show_once"=>"false"} {"signon.rememberSignons"=>"false"} {"javascript.options.showInConsole"=>"true"} {"app.update.auto"=>"false"} {"browser.EULA.3.accepted"=>"true"} {"browser.tabs.warnOnOpen"=>"false"} {"dom.disable_open_during_load"=>"false"} {"network.http.phishy-userpass-length"=>"255"} {"security.warn_entering_secure"=>"false"} {"browser.startup.homepage"=>"\"about:blank\""} {"browser.EULA.override"=>"true"} {"browser.dom.window.dump.enabled"=>"true"} {"browser.startup.page"=>"0"} {"browser.link.open_external"=>"2"} {"browser.search.update"=>"false"} {"browser.sessionstore.resume_from_crash"=>"false"} {"security.warn_viewing_mixed"=>"false"} {"dom.report_all_js_exceptions"=>"true"} {"webdriver_enable_native_events"=>false} {"devtools.errorconsole.enabled"=>"true"}
How do I get PHP to execute the shell_exec properly? The script works and my initial tests were run using firewatir (which shell_exec ran fine) but I am really wanting to use Watir-WebDriver instead of FireWatir - WatirWebDriver should be capable of running a Chrome browser (and IE on a Windows machine) while FireWatir can only run Firefox.
Thanks
Gabe
Here's my "Create Browser" code:
# Include the RubyGems file
require 'rubygems'
# Include the Watir-WebDriver file.
require 'watir-webdriver'
# Create the necessary objects
def create_browser(proxy)
# Setup the proper Firefox Profile
profile = Selenium::WebDriver::Firefox::Profile.new
profile.proxy = Selenium::WebDriver::Proxy.new :http => proxy
puts "<br>Using proxy " + proxy + "..."
#ff=FireWatir::Firefox.new :profile => profile
ff = Watir::Browser.new :firefox #, :profile => profile
puts "<br>Firefox ready..."
return ff
end
If the server is headless, you should install the headless gem so that Firefox can work.
require 'watir-webdriver'
require 'headless'
headless = Headless.new
headless.start
b = Watir::Browser.start 'www.google.com'
puts b.title
b.close
headless.destroy
See: http://watirwebdriver.com/headless/
It't a permission problem, the PHP script runs with the permissions of the server, normally apache.
You can do a sudo www and try to run the script then with rb to see if there is a problem when running ruby with the server user.
Put the two lines of code that is below at the very top of your PHP script. The result of this is that when you browse to your PHP page with your browser it will display exactly what the errors are, including any permission errors.
ini_set("display_errors",1);
error_reporting(E_ALL);
So a recent update to Firefox killed it's support for Watir (no JSSH update if I remember). As a result I rewrote what little code I had for Selenium::WebDriver. But I'm thinking that isn't particularly relevant (its included in case it is relevant I don't know it).
My ultimate solution was to use phpseclib. This allows me to SSH into the machine via their SSH2 PHP class. Once logged in as my typical username (with typical password) I was able to fire off a headless version of my script no problem. The only real issues this creates is that I now have to view everything that's going on through log files and screenshots but that was likely to be true no matter what solution I came up with.
phpseclib needs your username and password for the server (at least until you set some form of public private key pair). So I wouldn't want to do this on a publicly available machine without a couple of layers of security - like setting .htaccess to deny read access to the file with the login data, encrypting the password stored in the file, etc. However, for my purposes I'm logging into one machine on my LAN from another machine on my LAN. The password is only good on my LAN (not my web servers) and while my LAN can see out it should not be (easily) available to the rest of the world (to the best of my knowledge). So the security concerns are minimal.
I never did figure this out. Headless isn't the answer to getting PHP to exec the script. I'm pretty sure it is a permissions issue with Firefox's executable but I can't be positive until I find an actual fix.
Ultimately I've had to break up the tool where PHP manages the DB and task scheduling. Then PHP creates text files with all the data necessary for ruby to run the browser to right site, login, etc, etc... Then ruby moves the data file to one of a few different folders (success, failure, bad login, etc) and adds some text to the data file. Finally PHP parses all this info in the moved text files and updates the DB with that info.
It's less than ideal but it is getting the job done. Now I just need to figure out how to run all of this with mutliple threads...
Thanks for the help
I have a PHP script that calls a .bat file using system(). The output is written to the screen and I derive some values from parsing this output. This is running on windows 2003 IIS server. PHP v5.2.0
Specifically I am using this script to launch an Amazon EC2 instance and assign an IP address to it. It has worked great for me so far but recently the problem started.
Here is the code
$resultBatTemp = system("cmd /C C:\Inetpub\ec2\my_batch_file_to_launch_instance.bat");
$resultBat = (string)$resultBatTemp;
$instanceId = substr($resultBat, 9, 10);
...
Once I have this instace Id I can run another batch file that calls associates an ip address with this instance. It would appear that the instance does get launched but I never get the output on the screen.
For some reason this has all stopped working, the page freezes and never refreshes. I also need to completely exit safari or mozilla otherwise all pages from the website fail to load. Only when I relaunch the browser can i view the website again. I've connected to the webserver that hosts these scripts and checked PHP error log but nothing shows there. I've opened a DOS prompt and entered the code from the bat file that way and it connects to amazon and launches the instance fine. Ive isolated this bit of code and removed the system command and the rest of the script runs fine, so it appears that the hold up is with outputting the results of the bat file.
Recently I have purchased a new domain name for the site so this script is running from this domain. Might this cause the problem?
thanks
------------------------------------------------UPDATE-----------------------------------------------
Well hope this helps someone, I didnt find out what was wrong but created a new PHP file with a simple system command that called a .bat file, and a non-existent .bat file expecting to get an error back but nothing - just the usual hang for ages. So I restarted IIS and this fixed the problem. Dont know what was wrong but that did the trick.
Maybe first check what the system() call returns. According to documentation it will return FALSE in case of failure. Also, including your my_batch_file_to_launch_instance.bat in the question might help in solving it.
Try using the passthru function
Also make sure that all your commands are safe use escapeshellarg() or escapeshellcmd() to ensure that users cannot trick the system into executing arbitrary commands.
