Installing WAPT Server on a RedHat based distribution

***************************************
Setting up the RedHat based WAPT Server
***************************************

In order to install a fresh :red:`Redhat` or derivative host (virtual or physical) please refer to official documentation.

.. warning::

  * Install the server without the graphical user interface.

Configuring network parameters
==============================

.. include:: wapt-resources/linux-server-naming.txt

Configuring the name of the WAPT Server
=======================================

.. hint::

  The short name of the WAPT Server **MUST** not be longer than 15 characters (the limit is due to *sAMAccountName* restriction in Active Directory).

  The name of the WAPT Server **MUST** be a :abbr:`FQDN (Fully Qualified Domain Name)`, that is to say it has both the WAPT Server name and the DNS suffix.

* Modify the :file:`/etc/hostname` file and write the :term:`FQDN` of the WAPT Server.

.. code-block:: bash

  # /etc/hostname of the WAPT Server
  srvwapt.mydomain.lan

* Configure the :file:`/etc/hosts` file, be sure to put both the :term:`FQDN` and the short name of the WAPT Server.

.. code-block:: bash

  # /etc/hosts of the waptserver
  127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
  ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
  10.0.0.10   srvwapt.mydomain.lan srvwapt

.. hint::

  * On the line defining the DNS server IP address, be sure to have the IP of the WAPT Server (not 127.0.0.1), then the :term:`FQDN`, then the short name.

  * Do not change the line with :code:`localhost`.

Configuring the IP address of the WAPT Server
=============================================

* Modify the :file:`/etc/sysconfig/network-scripts/ifcfg-eth0` file and define a static IP address.
  The name of the file can be different, like :file:`ifcfg-ens0` for example.

.. code-block:: bash

  # /etc/sysconfig/network-scripts/ifcfg-eth0 of the WAPT Server
  TYPE="Ethernet"
  BOOTPROTO="static"
  NAME="eth0"
  ONBOOT="yes"
  IPADDR=10.0.0.10
  NETMASK=255.255.255.0
  GATEWAY=10.0.0.254
  DNS1=10.0.0.1
  DNS2=10.0.0.2

* Apply the network configuration by rebooting the host with a :command:`reboot`.

.. code-block:: bash

  reboot

* If it has not already been done, create the :ref:`DNS entry <srv_dns>` for the WAPT Server in the :term:`Organization`'s Active Directory or DNS server.

* After having rebooted, configure the system locale in English in order to have non-localized logs for easier searching of common errors.

.. code-block:: bash

  localectl set-locale LANG=en_US.utf8
  localectl status

* Check that the host clock is on time and that SELinux and the firewall are enabled.

.. code-block:: bash

  date
  sestatus
  systemctl status firewalld

* Check whether the machine is properly synchronized with NTP server.
  If it is not synchronized please refer to the OS documentation to configure :command:`timedatectl`.

.. code-block:: bash

  timedatectl status

* Update the distribution and set up the :abbr:`EPEL (Extra Packages for Enterprise Linux)` repository.

.. code-block:: bash

  yum update
  yum install epel-release wget sudo -y

The WAPT Server is now ready.

.. attention::

  The upgrade procedure is different from an initial installation.
  For an upgrade, please refer to :ref:`the documentation on upgrading the WAPT Server <upgrade-wapt>`.
