We detail here the software requirements for the machines used in your Datafari setup. It may vary based on your setup.

For all installations of Datafari :

• OS requirements :

  • Debian 10 (Buster) or 11 (Bullseye), or Ubuntu 20.04 (Focal) or 22.04 (Jammy) Environment 64 bits (a Docker image is available if you are on Windows environment) (available both for Datafari CE or Datafari EE)

  • CentOS or RedHat 7, 8 or 9 and CentOS Stream 7, 8 or 9 (available only for Datafari EE)

  • Recommended versions are Debian 11 or Ubuntu Jammy

Download dependencies scripts

You can download an init script (.sh) for Datafari :

• For Debian or Ubuntu users :

• For RedHat or CentOs users :

You can launch the script with this command :

source init_server_datafari.sh

=> It will install all the needed dependencies and increase the open files limit configuration.

Debian/Ubuntu installation

This part of the documentation is for Debian/Ubuntu users, if you are on CentOS please go to the next section.

• You need to have a Java JDK 11 (the JDK is mandatory if you use ELK, otherwise JRE is sufficient) installed on your environment (and you need to set the JAVA_HOME variable for all users and have the java executable in the PATH). To set it, we recommend to set it in /etc/profile :

  # For example if you want OpenJDK JDK 11 in Debian 10 apt-get install openjdk-11-jdk # Set Java Home nano /etc/profile #in the file add the line : export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 # Load the file source /etc/profile

  For now, Java 11 is the only version of Java supported by Datafari

On Debian 9 you have to add this prior to the installation of Java :

echo 'deb http://ftp.debian.org/debian stretch-backports main' | sudo tee /etc/apt/sources.list.d/stretch-backports.list
apt-get update

Mandatory dependencies :

apt-get install curl debconf unzip sudo libc6-dev jq lsof apache2 openssl libapache2-mod-jk iptables iptables-persistent python zip

Python is supported in version 2.7+ or 3+.

Centos/RedHat installation

• You need to have a Java JDK 11 (the JDK is mandatory if you use ELK, otherwise JRE is sufficient) installed on your environment (and you need to set the JAVA_HOME variable for all users and have the java executable in the PATH). To set it, we recommend to set it in /etc/profile :

yum update -y
echo "install java"
yum install java-11-openjdk-devel -y
echo 'export JAVA_HOME=/usr/lib/jvm/java-11' >> /etc/profile
source /etc/profile

yum install centos-release-scl epel-release sclo-cassandra3-jffi python27 
source /etc/profile
yum install jq lsof 
yum groupinstall "Development tools" 
yum install curl perl-Test-Simple perl-version perl-Data-Dumpe dpkg-devel dpkg-dev httpd mod_ssl iptables-services nc zip

In the Datafari 5.0 version on Centos version only, only Python 2.7 version is supported.

For all Operating Systems

• You need a user member of the sudo group to start Datafari (or it can be root user)  :

  visudo # add the line below root ALL=(ALL:ALL) ALL your_user ALL=NOPASSWD: ALL

• Increase Open Files limit configuration

  Change the setting in /etc/security/limits.conf : 

  echo 'root soft nofile 100000' >> /etc/security/limits.conf echo 'root hard nofile 100000' >> /etc/security/limits.conf echo 'datafari soft nofile 100000' >> /etc/security/limits.conf echo 'datafari hard nofile 100000' >> /etc/security/limits.conf echo '* soft nofile 100000' >> /etc/security/limits.conf echo '* hard nofile 100000' >> /etc/security/limits.conf echo 'root soft nproc 100000' >> /etc/security/limits.conf echo 'root hard nproc 100000' >> /etc/security/limits.conf echo 'datafari soft nproc 100000' >> /etc/security/limits.conf echo 'datafari hard nproc 100000' >> /etc/security/limits.conf echo '* soft nproc 100000' >> /etc/security/limits.conf echo '* hard nproc 100000' >> /etc/security/limits.conf

  Then reboot the machine to enable those parameters

• Make sure that the machine is always uptodate (in particular for the email alerts scheduler), by enabling: 

  ntpdate 0.fr.pool.ntp.org

• Set the locale setting (in the example with fr_FR but can be replaced with your locale) : 

  apt-get install locales locale-gen fr_FR.UTF-8 dpkg-reconfigure locales

  If you still have an error like "perl: warning: Setting locale failed."
  Do the additionnal steps :
  check the sshd configuration :

  nano /etc/ssh/sshd_config

  and comment the line :

  #AcceptEnv LANG LC_*

  Then relaunch the sshd service :

  /etc/init.d/ssh restart

  Add the locale variables to .bashrc configuration file :

  nano ~/.bashrc

  Add the lines :

  export LC_ALL="fr_FR.UTF-8" export LANG="fr_FR.UTF-8" export LANGUAGE="fr_FR.UTF-8"

  For PostgreSQL : 
  PostgreSQL needs to have the variables LANG and LC_* set. To check them, launch the command :

  locale

  If LC_ALL and LC_TYPE are not filled, enter this (for English language):

  export LC_ALL="en_US.UTF-8" export LC_CTYPE="en_US.UTF-8"

   You can also add the line to /etc/profile then.

  For OS X users : if you obtain the message : Cannot set LC_CTYPE to default locale: No such file or directory when you launch locale command, it might be because your terminal automatically sets environment variables when you log in from Mac to a Linux server : see https://askubuntu.com/a/778672 . To turn if off, uncheck the checkbox here : 

  In iTerm it is in the profile -> Terminal tab.

  In Terminal, it is in the Terminal -> Preferences -> Profiles -> Advanced tab

  • Set the timezone if needeed :
    Check the local zonetime that matches your region in /usr/share/zoneinfo. Then create a symlink from /etc/localtime (example here with Paris time) :

    sudo rm /etc/localtime sudo ln -s /usr/share/zoneinfo/Europe/Paris /etc/localtime

We detail here the software requirements for the machines used in your Datafari setup. It may vary based on your setup.

For all installations of Datafari :

• • OS requirements :

    • Debian 7+ or Ubuntu 16+ Environment 64 bits (a Docker image is available if you are on Windows environment)

    • CentOS or RedHat 7.0+ (only for Datafari EE)

  • Recommended versions are Debian 9 and Debian 8 (if you are on Debian 7 you will need to add the testing repo in /etc/apt/sources.list)

  • Starting from Datafari 4.1, Datafari does not embed its own Java component. You need to have a Java JRE 8 (or JDK 8) installed on your environment (and you need to set the JAVA_HOME variable for all users and have the java executable in the PATH). To set it, we recommend to set it in /etc/profile :
    

    # For example if you want OpenJDK JRE 8 apt-get install openjdk-8-jre # Set Java Home nano /etc/profile #in the file add the line : export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 # Load the file source /etc/profile

    For now, Java 8 is the only version of Java supported by Datafari

  • Debian/Ubuntu environment : requires unzip, sudo, libc6-dev, jq, lsof

    apt-get install curl debconf unzip sudo libc6-dev jq lsof netcat -y

    
    

  • Datafari needs Python v 2.7.x. !! If you have only Python v3, please install Python2 (for Ubuntu 16.04 for example, install the package python-minimal)

    apt-get install python -y

    
    

  • Needs a user member of the sudo group to start Datafari (or can be root user)  :

    visudo # add the line below root ALL=(ALL:ALL) ALL your_user ALL=NOPASSWD: ALL

    
    

  • Make sure that the machine is always uptodate (in particular for the email alerts scheduler), by enabling: 

    ntpdate 0.fr.pool.ntp.org

To turn if off, uncheck the checkbox here : 

    In iTerm it's in the profile -> Terminal tab.

    In Terminal, it's in the Terminal -> Preferences -> Profiles -> Advanced tab

    
    

  • Increase Open Files limit configuration

    For Debian, change the setting in /etc/security/limits.conf : 
    

    root soft nofile 100000 root hard nofile 100000 * soft nofile 100000 * hard nofile 100000 root soft nproc 100000 root hard nproc 100000 * soft nproc 100000 * hard nproc 100000

    
    Then reboot the machine to enable those parameters
    
    
    

  • Set the timezone if needeed :
