Installation#

To install Tango on Red Hat, here are the steps you should follow:

  1. Add the EPEL repository:

    sudo dnf install -y epel-release

  2. Add the MAX-IV’s public repository by creating the following file:

    sudo nano /etc/yum.repos.d/maxiv.repo

    [maxiv-public]
name=MAX IV public RPM Packages - $basearch
baseurl=http://pubrepo.maxiv.lu.se/rpm/el$releasever/$basearch
gpgcheck=0
enabled=1

    sudo dnf makecache

  3. Install and start MariaDB:

    sudo dnf install -y mariadb-server mariadb
sudo systemctl start mariadb
sudo systemctl enable mariadb

  4. Run mysql_secure_installation script:

    sudo mysql_secure_installation

  5. Install the tango Databaseds

    sudo dnf install -y tango-db

  6. Create TANGO database:

    cd /usr/share/tango-db/
sudo ./create_db.sh

  7. Set up TANGO environment:

    Note

    You should not use localhost as your TANGO_HOST. You can set the machine hostname using sudo hostnamectl set-hostname tangobox

    sudo nano /etc/tangorc

    For example:

    TANGO_HOST=tangobox:10000

  8. Set up environment variables:

    sudo nano /etc/profile.d/tango.sh

    For example:

    . /etc/tangorc
export TANGO_HOST

    sudo systemctl start tango-db
sudo systemctl enable tango-db

  10. Install Starter and TangoTest:

    sudo dnf install -y tango-starter tango-test

  11. Start and enable Starter:

    sudo systemctl start tango-starter
sudo systemctl enable tango-starter

    # Enabling powertools and javapackages-tools is required to install log4j12
sudo dnf config-manager --set-enabled powertools
sudo dnf module -y enable javapackages-tools
sudo dnf install -y tango-java

    sudo dnf install -y tango-java
