21.3.1.2 Installing NDB Cluster from RPM

This section covers the steps necessary to install the correct executables for each type of NDB Cluster node using RPM packages supplied by Oracle.

As an alternative to the method described in this section, Oracle provides MySQL Repositories for NDB Cluster 7.5.6 and later that are compatible with many common Linux distributions. Two repostories, listed here, are available for RPM-based distributions:

• For distributions using yum or dnf, you can use the MySQL Yum Repository for NDB Cluster. See Installing MySQL NDB Cluster Using the Yum Repository, for instructions and additional information.

• For SLES, you can use the MySQL SLES Repository for NDB Cluster. See Installing MySQL NDB Cluster Using the SLES Repository, for instructions and additional information.

RPMs are available for both 32-bit and 64-bit Linux platforms. The filenames for these RPMs use the following pattern:

mysql-cluster-community-data-node-7.5.8-1.el7.x86_64.rpm

mysql-cluster-license-component-ver-rev.distro.arch.rpm

    license:= {commercial | community}

    component: {management-server | data-node | server | client | other—see text}

    ver: major.minor.release

    rev: major[.minor]

    distro: {el6 | el7 | sles12}

    arch: {i686 | x86_64}

license indicates whether the RPM is part of a Commercial or Community release of NDB Cluster. In the remainder of this section, we assume for the examples that you are installing a Community release.

Possible values for component, with descriptions, can be found in the following table:

Table 21.5 Components of the NDB Cluster RPM distribution

A single bundle (.tar file) of all NDB Cluster RPMs for a given platform and architecture is also available. The name of this file follows the pattern shown here:

mysql-cluster-license-ver-rev.distro.arch.rpm-bundle.tar

You can extract the individual RPM files from this file using tar or your preferred tool for extracting archives.

The components required to install the three major types of NDB Cluster nodes are given in the following list:

• Management node: management-server

• Data node: data-node

• SQL node: server and common

In addition, the client RPM should be installed to provide the ndb_mgm management client on at least one management node. You may also wish to install it on SQL nodes, to have mysql and other MySQL client programs available on these. We discuss installation of nodes by type later in this section.

ver represents the three-part NDB storage engine version number in 7.6.x format, shown as 7.6.32 in the examples. rev provides the RPM revision number in major.minor format. In the examples shown in this section, we use 1.1 for this value.

The distro (Linux distribution) is one of rhel5 (Oracle Linux 5, Red Hat Enterprise Linux 4 and 5), el6 (Oracle Linux 6, Red Hat Enterprise Linux 6), el7 (Oracle Linux 7, Red Hat Enterprise Linux 7), or sles12 (SUSE Enterprise Linux 12). For the examples in this section, we assume that the host runs Oracle Linux 7, Red Hat Enterprise Linux 7, or the equivalent (el7).

arch is i686 for 32-bit RPMs and x86_64 for 64-bit versions. In the examples shown here, we assume a 64-bit platform.

The NDB Cluster version number in the RPM file names (shown here as 7.6.32) can vary according to the version which you are actually using. It is very important that all of the Cluster RPMs to be installed have the same version number. The architecture should also be appropriate to the machine on which the RPM is to be installed; in particular, you should keep in mind that 64-bit RPMs (x86_64) cannot be used with 32-bit operating systems (use i686 for the latter).

Data nodes.  On a computer that is to host an NDB Cluster data node it is necessary to install only the data-node RPM. To do so, copy this RPM to the data node host, and run the following command as the system root user, replacing the name shown for the RPM as necessary to match that of the RPM downloaded from the MySQL website:

$> rpm -Uhv mysql-cluster-community-data-node-7.6.32-1.el7.x86_64.rpm

This installs the ndbd and ndbmtd data node binaries in /usr/sbin. Either of these can be used to run a data node process on this host.

SQL nodes.  Copy the server and common RPMs to each machine to be used for hosting an NDB Cluster SQL node (server requires common). Install the server RPM by executing the following command as the system root user, replacing the name shown for the RPM as necessary to match the name of the RPM downloaded from the MySQL website:

$> rpm -Uhv mysql-cluster-community-server-7.6.32-1.el7.x86_64.rpm

This installs the MySQL server binary (mysqld), with NDB storage engine support, in the /usr/sbin directory. It also installs all needed MySQL Server support files and useful MySQL server programs, including the mysql.server and mysqld_safe startup scripts (in /usr/share/mysql and /usr/bin, respectively). The RPM installer should take care of general configuration issues (such as creating the mysql user and group, if needed) automatically.

Important

You must use the versions of these RPMs released for NDB Cluster; those released for the standard MySQL server do not provide support for the NDB storage engine.

To administer the SQL node (MySQL server), you should also install the client RPM, as shown here:

$> rpm -Uhv mysql-cluster-community-client-7.6.32-1.el7.x86_64.rpm

This installs the mysql client and other MySQL client programs, such as mysqladmin and mysqldump, to /usr/bin.

Management nodes.  To install the NDB Cluster management server, it is necessary only to use the management-server RPM. Copy this RPM to the computer intended to host the management node, and then install it by running the following command as the system root user (replace the name shown for the RPM as necessary to match that of the management-server RPM downloaded from the MySQL website):

$> rpm -Uhv mysql-cluster-community-management-server-7.6.32-1.el7.x86_64.rpm

This RPM installs the management server binary ndb_mgmd in the /usr/sbin directory. While this is the only program actually required for running a management node, it is also a good idea to have the ndb_mgm NDB Cluster management client available as well. You can obtain this program, as well as other NDB client programs such as ndb_desc and ndb_config, by installing the client RPM as described previously.

Note

Previously, ndb_mgm was installed by the same RPM used to install the management server. In NDB 7.5 (and later), all NDB client programs are obtained from the same client RPM that installs mysql and other MySQL clients.

See Section 2.5.5, “Installing MySQL on Linux Using RPM Packages from Oracle”, for general information about installing MySQL using RPMs supplied by Oracle.

After installing from RPM, you still need to configure the cluster; see Section 21.3.3, “Initial Configuration of NDB Cluster”, for the relevant information.

See Section 2.5.5, “Installing MySQL on Linux Using RPM Packages from Oracle”, for general information about installing MySQL using RPMs supplied by Oracle. See Section 21.3.3, “Initial Configuration of NDB Cluster”, for information about required post-installation configuration.
