Installation on Red Hat/CentOS

Attention

LL::NG requires at least Red Hat/CentOS 7

Organization

LemonLDAP::NG provides packages for Red Hat/Centos 7:

  • lemonldap-ng: metapackage, contains no file but dependencies on other packages
  • lemonldap-ng-doc: contains HTML documentation and project docs (README, etc.)
  • lemonldap-ng-conf: contains default configuration (DNS domain: example.com)
  • lemonldap-ng-test: contains sample CGI test page
  • lemonldap-ng-handler: contains Apache Handler implementation (agent)
  • lemonldap-ng-manager: contains administration interface and session explorer
  • lemonldap-ng-portal: contains authentication portal and menu
  • lemonldap-ng-fastcgi-server: FastCGI server needed to use Nginx
  • lemonldap-ng-nginx: contains Nginx configuration and dependencies
  • lemonldap-ng-uwsgi-app: contains Uwsgi application
  • perl-Lemonldap-NG-Common: CPAN - Shared modules
  • perl-Lemonldap-NG-Handler: CPAN - Handler modules
  • perl-Lemonldap-NG-Manager: CPAN - Manager modules
  • perl-Lemonldap-NG-Portal: CPAN - Portal modules

Danger

The package lemonldap-ng-nginx requires the nginx community package. If you use openrestry or Nginx plus, you must ignore this dependency. To do this, download the package and install it with:

rpm --nodeps -i lemonldap-ng-nginx*.rpm

Get the packages

YUM repository

You can add this YUM repository to get recent packages:

vi /etc/yum.repos.d/lemonldap-ng.repo

[lemonldap-ng]
name=LemonLDAP::NG packages
baseurl=https://lemonldap-ng.org/redhat/stable/$releasever/noarch
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-OW2

Tip

Replace stable by 2.0 to avoid upgrade to next major version

You may also need some extras packages, available here:

[lemonldap-ng-extras]
name=LemonLDAP::NG extra packages
baseurl=https://lemonldap-ng.org/redhat/extras/$releasever
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-OW2

Run this to update packages cache:

yum update

Danger

You must also install the EPEL repository for non-core dependencies. See prerequisites and dependencies chapter for more.

Manual download

RPMs are available on the Download page.

Package GPG signature

The GPG key can be downloaded here: image0

Install it to trust RPMs:

curl https://lemonldap-ng.org/_media/rpm-gpg-key-ow2 > /etc/pki/rpm-gpg/RPM-GPG-KEY-OW2

Install packages

With YUM

If the packages are stored in a yum repository:

yum install lemonldap-ng

You can also use yum on local RPMs file:

yum localinstall lemonldap-ng-* perl-Lemonldap-NG-*

With RPM

Before installing the packages, install all dependencies.

You have then to install all the downloaded packages:

rpm -Uvh lemonldap-ng-* perl-Lemonldap-NG-*

Tip

You can choose to install only one component by choosing the package lemonldap-ng-portal, lemonldap-ng-handler or lemonldap-ng-manager.

Install the package lemonldap-ng-conf on all server which contains one of those packages.

First configuration steps

Change default DNS domain

By default, DNS domain is example.com. You can change it quick with a sed command. For example, we change it to ow2.org:

sed -i 's/example\.com/ow2.org/g' /etc/lemonldap-ng/* /var/lib/lemonldap-ng/conf/lmConf-1.json /etc/nginx/conf.d/* /etc/httpd/conf.d/*

Upgrade

If you upgraded LL::NG, check all upgrade notes.

DNS

Configure your DNS server to resolve names with your server IP:

  • auth.<your domain>: main portal, must be public
  • manager.<your domain>: manager, only for adminsitrators
  • test1.<your domain>, test2.<your domain>: sample applications

Follow the next steps

File location

  • Configuration is in /etc/lemonldap-ng
  • LemonLDAP::NG configuration (edited by the Manager) is in /var/lib/lemonldap-ng/conf/
  • All Perl modules are in the VENDOR perl directory
  • All Perl scripts/pages are in /var/lib/lemonldap-ng/
  • All static content (examples, CSS, images, etc.) is in /usr/share/lemonldap-ng/

Build your packages

If you need it, you can rebuild RPMs:

  • Install rpm-build package
  • Install all build dependencies (see BuildRequires in lemonldap-ng.spec)
  • Put LemonLDAP::NG tarball in %_topdir/SOURCES
  • Edit ~/.rpmmacros and set your build parameters:
%_topdir /home/user/build
%dist .el7
%rhel 7
  • Go to %_topdir
  • Build:
rpmbuild -ta SOURCES/lemonldap-ng-VERSION.tar.gz
