To deploy NuoDB in a production environment, you must deploy on one of the following supported Linux platforms. To develop or test/evaluate NuoDB, you can use any of the following platforms:
Red Hat Enterprise Linux (RHEL) / CentOS 7.7 and later
Red Hat Enterprise Linux (RHEL) 8.x
Development / Test
Hosts that run NuoDB must install the following services:
NuoDB requires that either the Java Runtime Environment (JRE) or Java Development Kit (JDK) be installed. The following Java versions are supported:
Only 64-bit JRE and JDK are supported.
The NuoDB Command (
nuocmd) interface requires Python 3.6 or later.
Red Hat Enterprise Linux (RHEL) Prerequisites
ncurses-compat-libs library is required to install NuoDB.
ncurses is used by
nuosql to implement command line editing capabilities.
Please check for its existence prior to your NuoDB install.
If it is not installed, please follow your OS installation instructions to install this library.
For example, if using the
yum package installer, run:
sudo yum install ncurses-compat-libs
Domain and database management in NuoDB deployments is handled by NuoDB Admin. NuoDB Admin supports TLS encryption for all processes in the domain.
To use NuoDB Admin with TLS encryption, TLS must be enabled. For more information, see Enabling TLS Encryption.
To use NuoDB Admin without TLS encryption, see Managing TLS Security.
LDAP requirements on Red Hat / CentOS Linux is as follows:
sudo yum install openldap-clients
On Windows, there are no additional requirements.
Minimum Recommended Hardware
x86_64 dual core CPU, 1.6GHz
For Linux, it is highly recommended that your file system support
fallocate() system call is supported by the following:
XFS(since Linux kernel 2.6.38)
ext4(since Linux kernel 3.0)
ZFS((since ZFS on Linux kernel 0.6.4)
Btrfs(since Linux kernel 3.7)
tmpfs(since Linux kernel 3.5)
|Network File System (NFS) storage is not supported for archive and journal locations.|
NuoDB supports Intel Nehalem or later processors only. In order to determine if the machine processor on Linux is Nehalem or later run the following command:
grep sse4_2 /proc/cpuinfo | sort -u
If the command returns text output then the processor type is supported.
VMware VMOTION Considerations
If you are using VMotion to migrate NuoDB virtual machines between servers, NuoDB strongly recommends that you stop any running NuoDB process(es) within the virtual machine prior to migration, and restart the NuoDB process(es) after the migration. This is because VMotion can cause running NuoDB process(es) to stop unexpectedly. If VMotion is used while NuoDB processes are still running, you must check the status of the NuoDB processes after migration then manually restart any stopped processes when migration is complete.
