Server Automation for NodeJS over SSH

# nodemiral-forcetty
### Server Automation for NodeJS over SSH
Fork of arunoda's nodemiral with some hacks to run on RHEL/CentOS 7+

## Install
~~~js
npm install nodemiral-forcetty
~~~

## Features

* Support connecting to any unix remote server
* Authenticate with password (using [`sshpass`](http://sourceforge.net/projects/sshpass/)) or with a `pem` file
* Can work with multiple servers at once
* Supports, `copy`, `execute` and `executeScript` at core methods
* Familiar NodeJS API

## Example
~~~js
var nodemiral = require('nodemiral');
var session = nodemiral.session('hostname', {username: 'root', password: 'password'});

session.execute('uname -a', function(err, code, logs) {
  console.log(logs.stdout);
});

## API

### Session

Create a session to a remote server. You can invoke following methods after created a session.

    @param hostname - hostname or ip addess
    @param auth - object containing following fields: `username` and (`password` or `pem`)
    @param options - object of options described below
    nodemiral.session(hostname, auth, options);

`options`:

* `ejs` - ejs options with `ejs` fields
* `ssh` - object whose key and value will be passed as `-o key:value` to any ssh session. For example `{ 'StrictHostKeyChecking': 'no', 'UserKnownHostsFile': '/dev/null' }`

### Session Methods

#### execute
execute given shell command on the remote server.

    @param shellCommand - shellCommand
    @param options - {onStdout, onStderr}
    @param callback - callback containing following parameters
      err - err if exists
      code - status code of the ssh process
      logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
    session.execute(shellCommand, callback);

#### executeScript
execute a local shell script in the remote server. You can template shell script with [EJS](https://github.com/visionmedia/ejs).

    @param localScriptFile - localScriptFile
    @param templateVars - variables to the template if uses ejs in the script
    @param options - {onStdout, onStderr}
    @param callback - callback containing following parameters
      err - err if exists
      code - status code of the ssh process
      logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
    session.executeScript(localScriptFile, templateVars, callback);

#### copy
copy a file from local machine to the remote machine. Supports binary files too. Support EJS templating with non-binary files.

    @param localFile - localFile
    @param remoteFileLocation - remoteFileLocation
    @param options - {onStdout, onStderr}
    @param callback - callback containing following parameters
      err - err if exists
      code - status code of the ssh process
      logs - {stdout: 'stdout logs', stderr: 'stderr logs'}
    session.copy(localFile, remoteFileLocation, templateVars, callback)
