How to Change Bootstrap Carousel Slide Speed

The speed cannot be controlled by the API. Though you can modify CSS that is in charge of that. find in the bootstrap.css file:

.carousel-inner > .item {
    position: relative;
    display: none;
    -webkit-transition: 0.6s ease-in-out left;
    -moz-transition: 0.6s ease-in-out left;
    -o-transition: 0.6s ease-in-out left;
    transition: 0.6s ease-in-out left;
}

and change 0.6s to the time you want. You also might want to edit time in the function call below:

.emulateTransitionEnd(2000)

at bootstrap.js in function Carousel.prototype.slide. That synchronize transition and prevent slide to disapear before transition ends.

PHP: How to run / execute a script in the background forever through SSH ?

You can execute a php script in the background forever by using SSH through PHP but for that you have to make sure first that SSH2 extension is available.

PHP DOCS: http://www.php.net/manual/en/function.ssh2-exec.php

$connection = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($connection, 'username', 'password');

/* if you want to execute script from a different directory then use commands in same line separated 
   by ';', that is required in php.
   In below second command '&' will do the magic to run command forever.
*/ 
$stream = ssh2_exec($connection, 'cd httpdocs/subdir/dir; /path/to/php server.php &'); 
$stream = ssh2_exec($connection, 'ps aux | grep server.php'); 

// printing ssh output on screen
stream_set_blocking($stream, true);
$stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO);
echo stream_get_contents($stream_out); 
// closing ssh connection
$stream = ssh2_exec($connection, 'exit'); 
unset($connection);

If you want to do same thing through SSH Terminal (PuTTY) then follow this tutorial:

SSH: how to run a PHP script in background forever in Linux (CentOS) ?

If you want to run a PHP script in the background forever through SSH then follow these steps:

If you are using a SSH terminal (PuTTY) then directly run following command:

// Notice '&'; that operator will help to run this script forever.
php server.php &

// make sure that you are in the root directory of server.php

ssh outpout

Now your script is running in background and will keep running indefinitely even after closing terminal.

To check if your script is running or not You can run following command:

ps aux | grep server.php

If you want to do same thing through PHP instead of terminal then follow this tutorial:

How to install Node.js on Linux CentOS from the EPEL Repository?

An alternative installation method uses the EPEL (Extra Packages for Enterprise Linux) repository that is available for CentOS and related distributions.

To gain access to the EPEL repo, you must modify the repo-list of your installation. Fortunately, we can reconfigure access to this repository by installing a package available in our current repos called epel-release.

sudo yum install epel-release
Now that you have access to the EPEL repository, you can install Node.js using your regular yum commands:

sudo yum install nodejs
Once again, you can check that the installation was successful by asking Node to return its version number:

node –version
v0.10.30

Tested on CentOS 6.7 x64
