 lets get started first SSH into your remote machine and enter:

/usr/sbin/useradd nagios
passwd nagios
this will setup a new Nagios user, now we need to install some plugins:

wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.14.tar.gz
tar -xzf nagios-plugins-1.4.14.tar.gz
cd nagios-plugins-1.4.14
sudo ./configure --with-nagios-user=nagios --with-nagios-group=nagios

Multiple github account SSH key switch
github using SSH connection with the client. If it is a single-user (first), generate a key pair, the public key saved to github, each time you connect the SSH client sends local private key (default ~ / .ssh / id_rsa) to the service-side validation. Single-user case, the connection saved on the server's private key and send the public key is naturally paired. But if it is a multi-user (first, second), we are connected to the second account when, second save their own public key, but still send the default SSH client private key, the private key that is first, then the verification will naturally be through. However, to achieve multiple accounts under the SSH key to switch on the client to do some configuration can be.
First, cd to ~ /. Ssh using ssh-keygen-t-rsa-C 'second@mail.com' to generate new SSH key: id_rsa_second, after generating a new SSH public key will be added to github.
ssh-keygen-t-rsa-C 'second@mail.com'
Default SSH only reads id_rsa, so in order to allow

####1. generate a private key on the Linux server that runs Apache webserver using openssl command as shown below.

# openssl genrsa -out www.thegeekstuff.com.key 1024
Generating RSA private key, 1024 bit long modulus
.......................................++++++...................................................++++++

Enter pass phrase for www.thegeekstuff.com.key:
Verifying - Enter pass phrase for www.thegeekstuff.com.key:

The generated private key looks like the following.
