This document contains instructions for:
WARNING: DO THIS ON A DEDICATED VM OR A NON-PRODUCTION SYSTEM!
THE BUILD SCRIPT WILL MAKE CHANGES TO THE SYSTEM THAT MAY BE INCOMPATIBLE WITH OTHER SOFTWARE
Note: The current Windows pre-build script is written in batch and must be executed by cmd.exe. For this reason, any Windows commands listed in this document will be written with cmd.exe compatibility in mind.
Note: The current Windows build should be run on a Windows machine without Python installed.
From a command prompt with Administrative priveleges run:
cd /path/to/ncpa/build/ build_windows.bat
This will use Chocolatey to install various prerequisites for building NCPA and then build NCPA. If you have not yet built NCPA 3 on your machine, the script will likely tell you that a reboot is required/pending. This means that you need to restart your machine and then rerun the script and it will continue the installation/build processes. This may happen several times during the installation process.
This will create a file called ncpa-<version>.exe in the build directory.
This is the installer for NCPA and can be used to install NCPA on a Windows system.
Building on CentOS 7 is the easiest way to get a working package for all Linux distributions. When you build on CentOS 7, both a .deb as well as an .rpm package are built.
In most cases, building on the distribution that is targeted, e.g. building on Ubuntu 20.04 to deploy on Ubuntu 20.04, will work, but the resulting package will not be as portable.
To start, clone the repository in your directory:
cd ~ git clone https://github.com/NagiosEnterprises/ncpa
Now run the setup scripts as root to install the requirements:
cd ncpa/build ./build.sh
Follow the prompts to setup the system. When running the build.sh script it will setup the system and build the ncpa binary.
Copy the resulting ~/ncpa/build/ncpa-3.X.X-latest.x86_64.rpm or ncpa_3.X.X-latest_amd64.deb to the desired server and install using the appropriate package system:
On CentOS/RHEL/Oracle/Amazon/Rocky:
yum install ./ncpa-3.X.X-latest.x86_64.rpmOn Ubuntu 18+/Debian 10+:
dpkg -i ./ncpa_3.X.X-latest._amd64.debOn Ubuntu 14-16/Debian 8-9 (not supported, but may work):
dpkg --force-depends -i ./ncpa_3.X.X-latest._amd64.debOn OpenSuSE/SLES:
zypper install ./ncpa-3.X.X-latest.x86_64.rpm
Not updated for v3, yet. It's basically the same as Linux, however you may need to install the libraries and python differently, due to it being macOS. You must have python3, wget and git installed prior to building NCPA v3.x.:
Clone the repository into your directory:
cd ~ git clone https://github.com/NagiosEnterprises/ncpa
Make your user root, and install the xcode command line tools:
sudo su - xcode-select --install
Execute the build script:
cd ~/ncpa/build ./build.sh
Note that there may be some difficulty with installing this on other machines without Apple Developer credentials, and with the enhanced system security in newer versions. Please see Installing on Nagios NCPA v 2.4 Agent on MacOS for more information.
There are plenty of derivative operating systems that will not work by following just the instructions given in this document. NCPA is capable of being built on any system that supports Python, so not to worry - it is possible!
The common problem is going to be getting the libraries for all the python modules to be compiled and behave correctly with Python. We recommend compiling them from source if you must, and compiling Python from source too - with any changes you need to give the Python build process for library locations. Once that's done, you can continue by installing the required pip modules and trying the build process.
