Nagios Install on Debian

Based on this (but it's got an awful understanding about install locations on debian)
Note Debian does not package nagios anymore, so that's why this has to be done..

Run it as root..

The following steps describes how to install the latest version of Nagios Core from source.

Start by installing the following packages that are necessary for compiling and running Nagios: 

apt update && apt upgrade
apt install autoconf gcc libc6 make wget unzip apache2 php libapache2-mod-php7.0 libgd-dev \ 
       libmcrypt-dev libssl-dev bc gawk dc build-essential libnet-snmp-perl gettex
cd /usr/src/ wget https://github.com/NagiosEnterprises/nagioscore/archive/nagios-4.4.3.tar.gz tar zxf nagios-*.tar.gz cd nagioscore-nagios-*/
note that this is where most documents are messed up - resulting binaries/stuff end up in the wrong place.

./configure --prefix=/usr --with-httpd-conf=/etc/apache2/conf-enabled \
           --sysconfdir=/etc/nagios --with-lockfile=/var/lock/nagios \
           --datarootdir=/usr/share/nagios --localstatedir=/var/lib/nagios \
           --with-cgibindir=/usr/lib/cgi-bin  --sbindir=/usr/lib/cgi-bin \
           --with-logdir=/var/log/nagios

Upon successful completion, you will see the following message:

 *** Configuration summary for nagios 4.4.3 2019-01-15 ***:

  General Options:
 -------------------------
        Nagios executable:  nagios
        Nagios user/group:  nagios,nagios
       Command user/group:  nagios,nagios
             Event Broker:  yes
        Install ${prefix}:  /usr
    Install ${includedir}:  /usr/include/nagios
                Lock file:  /var/lock/nagios
   Check result directory:  /var/lib/nagios/spool/checkresults
           Init directory:  /etc/init.d
  Apache conf.d directory:  /etc/apache2/conf-enabled
             Mail program:  /usr/bin/mail
                  Host OS:  linux-gnu
          IOBroker Method:  epoll

Web Interface Options:
 ------------------------
                 HTML URL:  http://localhost/nagios/
                  CGI URL:  http://localhost/nagios/cgi-bin/
 Traceroute (used by WAP):  /usr/sbin/traceroute


Review the options above for accuracy.  If they look okay,
tMype 'make all' to compile the main program and CGIs.

Now make it..

make all
make install-groups-users
usermod -a -G nagios www-data
usermod --shell /bin/bash nagios
make install
make install-commandmod
make install-config
make install-webconf
a2enmod rewritesudo a2enmod cgi
sudo make install-daemoninit
mkdir /var/lib/nagios/rw
chown nagios  /var/lib/nagios/rw

sudo htpasswd -c /etc/nagios/htpasswd.users nagiosadmin

/etc/init.d/apache2 restart
/etc/init.d/nagios restart
To access the Nagios web interface open your favorite browser and type your server's domain name or public IP address followed by /nagios: 
http(s)://your_domain_or_ip_address/nagios

Enter the nagiosadmin

Getting the web to work...

I could not get nagios to read the apache logged in user so I had to modify cgi.cfg to set
use_authentication=0 
default_user_name=nagiosadmin
It's behind httpaccess... so it looks like it's just not picking up the username..

modify /etc/nagios/resource.cfg - set the correct plugin path

$USER1$=/usr/lib/nagios/plugins
