This section provides information about compiling NDB Cluster on Linux and other Unix-like platforms. Building NDB Cluster from source is similar to building the standard MySQL Server, although it differs in a few key respects discussed here. For general information about building MySQL from source, see Installing MySQL from Source. For information about compiling NDB Cluster on Windows platforms, see Section 3.2.2, “Compiling and Installing NDB Cluster from Source on Windows”.
Building MySQL NDB Cluster 8.0 requires using the MySQL Server
8.0 sources. These are available from the MySQL downloads page
at https://dev.mysql.com/downloads/. The archived source file
should have a name similar to
mysql-8.0.37.tar.gz
. You
can also obtain the sources from GitHub at
https://github.com/mysql/mysql-server.
In previous versions, building of NDB Cluster from standard MySQL Server sources was not supported. In MySQL 8.0 and NDB Cluster 8.0, this is no longer the case—both products are now built from the same sources.
The WITH_NDB
option for
CMake causes the binaries for the management
nodes, data nodes, and other NDB Cluster programs to be built;
it also causes mysqld to be compiled with
NDB
storage engine support. This
option (or, prior to NDB 8.0.31,
WITH_NDBCLUSTER
) is required when
building NDB Cluster.
The WITH_NDB_JAVA
option is
enabled by default. This means that, by default, if
CMake cannot find the location of Java on
your system, the configuration process fails; if you do not
wish to enable Java and ClusterJ support, you must indicate
this explicitly by configuring the build using
-DWITH_NDB_JAVA=OFF
. Use
WITH_CLASSPATH
to provide the
Java classpath if needed.
For more information about CMake options specific to building NDB Cluster, see CMake Options for Compiling NDB Cluster.
After you have run make && make install (or your system's equivalent), the result is similar to what is obtained by unpacking a precompiled binary to the same location.
Management nodes.
When building from source and running the default
make install, the management server and
management client binaries (ndb_mgmd and
ndb_mgm) can be found in
/usr/local/mysql/bin
. Only
ndb_mgmd is required to be present on a
management node host; however, it is also a good idea to have
ndb_mgm present on the same host machine.
Neither of these executables requires a specific location on
the host machine's file system.
Data nodes.
The only executable required on a data node host is the data
node binary ndbd or
ndbmtd. (mysqld, for
example, does not have to be present on the host machine.) By
default, when building from source, this file is placed in the
directory /usr/local/mysql/bin
. For
installing on multiple data node hosts, only
ndbd or ndbmtd need be
copied to the other host machine or machines. (This assumes
that all data node hosts use the same architecture and
operating system; otherwise you may need to compile separately
for each different platform.) The data node binary need not be
in any particular location on the host's file system, as long
as the location is known.
When compiling NDB Cluster from source, no special options are
required for building multithreaded data node binaries.
Configuring the build with NDB
storage engine support causes ndbmtd to be
built automatically; make install places the
ndbmtd binary in the installation
bin
directory along with
mysqld, ndbd, and
ndb_mgm.
SQL nodes.
If you compile MySQL with clustering support, and perform the
default installation (using make install as
the system root
user),
mysqld is placed in
/usr/local/mysql/bin
. Follow the steps
given in Installing MySQL from Source to make
mysqld ready for use. If you want to run
multiple SQL nodes, you can use a copy of the same
mysqld executable and its associated
support files on several machines. The easiest way to do this
is to copy the entire /usr/local/mysql
directory and all directories and files contained within it to
the other SQL node host or hosts, then repeat the steps from
Installing MySQL from Source on each machine. If you
configure the build with a nondefault PREFIX
option, you must adjust the directory accordingly.
In Section 3.3, “Initial Configuration of NDB Cluster”, we create configuration files for all of the nodes in our example NDB Cluster.
