Server prerequisites - Linux

The following prerequisites must be met to install ERA Server on Linux:

You must have a valid license.

A database server must be installed and configured with a root account. A user account does not have to be created prior to the installation, the installer can create the account.
validation-status-icon-infoNOTE: ERA Server stores large data blobs in the database, therefore it is necessary to configure MySQL to accept large packet size for ERA to run properly.

ODBC Driver - ODBC Driver is used to establish connection with the database server (MySQL / MS SQL).

Configure the server installation file set as an executable. To do so, use the following terminal command:

chmod +x

The minimum supported version of openSSL is openssl-1.0.1e-30; openssl 1.1.* and later is not supported (the command openssl version shows current version).

Xvfb - Required for proper report printing (Generate Report) on Linux Server systems without a graphical interface.

Cifs-utils - Required for proper Agent deployment to a Windows OS.

Qt4 WebKit libraries - Used for printing reports to PDF and PS format (must be version 4.8, not 5). All other Qt4 dependencies will be installed automatically. In the case of CentOS, there may be no package in the official repositories. You can install it from a third-party repository (for example EPEL repositories) or compile it yourself on a target machine.

Kinit + klist - Used for Kerberos authentication during the AD synchronization task and login with a domain user. Also a proper Kerberos configuration is required (/etc/krb5.conf).

Wbinfo + ntlm auth - Used for authentication with the domain accounts + NTLM authentication with SMTP server (sending emails).

Ldapsearch - Used in AD synchronization task.

Snmptrap - Used to send SNMP traps. Optional if this functionality won’t be used. SNMP also requires configuration.

SELinux devel package - Used during product installation to build SELinux policy modules. This is only required on systems with SELinux enabled (CentOS, Fedora, RHEL). SELinux may cause problems with other applications. For ERA Server it is not necessary.


The table below contains the appropriate terminal commands for each package described above for both Debian and Ubuntu distributions and Centos, Red Hat and Fedora distributions:
