Software requirements

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 :

Open

• For RedHat or CentOs users :

Open

You can launch the script with this command :

=> 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 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 :

Mandatory dependencies :

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 :

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)  :

• Increase Open Files limit configuration

  Change the setting in /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: 

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

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

  and comment the line :

  Then relaunch the sshd service :

  Add the locale variables to .bashrc configuration file :

  Add the lines :

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

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

   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) :
