Server prerequisites - Linux

The following prerequisites must be met to install the ESMC 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. MS SQL Server on Linux is not supported. However, you can connect the ESMC Server on Linux to MS SQL Server on Windows.

note

Note

The ESMC Server stores large data blobs in the database. Configure MySQL to accept large packet size for ESMC to run properly.

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

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

chmod +x server-linux-x86_64.sh

We recommend that you use the latest OpenSSL version (1.1.1). The minimum supported version of OpenSSL is openssl-1.0.1e-30. There can be more versions of OpenSSL installed on one system in the same time. At least one supported version must be present on you system.

oYou can use the command openssl version to show current default version.

oYou can list all versions of OpenSSL present on your system. See the file names endings listed using the command sudo find / -iname *libcrypto.so*

oFedora Linux users should use compat-openssl10 package.

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 - Kerberos is used for authentication of a domain user when logging in and Active Directory synchronization task. Make sure your Kerberos configured properly (/etc/krb5.conf). ESMC 7.2 supports synchronization with multiple domains.

ldapsearch - Used in AD synchronization task and for authorization.

snmptrap - Used to send SNMP traps. If the functionality will not be used, this is optional. 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 ESMC Server it is not necessary.
