After completing the installation, do not yet start any of the binaries. We show you how to do so following the configuration of the nodes (seeSection 25.3.3, “Initial Configuration of NDB Cluster”).

1. Check your/etc/passwd and/etc/group files (or use whatever tools are provided by your operating system for managing users and groups) to see whether there is already amysql group andmysql user on the system. Some OS distributions create these as part of the operating system installation process. If they are not already present, create a newmysql user group, and then add amysql user to this group:

   $> groupadd mysql$> useradd -g mysql -s /bin/false mysql

   The syntax foruseradd andgroupadd may differ slightly on different versions of Unix, or they may have different names such asadduser andaddgroup.

2. Change location to the directory containing the downloaded file, unpack the archive, and create a symbolic link namedmysql to themysql directory.

   Note

   The actual file and directory names vary according to the NDB Cluster version number.

   $> cd /var/tmp$> tar -C /usr/local -xzvf mysql-cluster-gpl-8.0.43-linux-glibc2.12-x86_64.tar.gz$> ln -s /usr/local/mysql-cluster-gpl-8.0.43-linux-glibc2.12-x86_64 /usr/local/mysql

3. Change location to themysql directory and set up the system databases usingmysqld--initialize as shown here:

   $> cd mysql$> mysqld --initialize

   This generates a random password for the MySQLroot account. If you donot want the random password to be generated, you can substitute the--initialize-insecure option for--initialize. In either case, you should reviewSection 2.9.1, “Initializing the Data Directory”, for additional information before performing this step. See alsoSection 6.4.2, “mysql_secure_installation — Improve MySQL Installation Security”.

4. Set the necessary permissions for the MySQL server and data directories:

   $> chown -R root .$> chown -R mysql data$> chgrp -R mysql .

5. Copy the MySQL startup script to the appropriate directory, make it executable, and set it to start when the operating system is booted up:

   $> cp support-files/mysql.server /etc/rc.d/init.d/$> chmod +x /etc/rc.d/init.d/mysql.server$> chkconfig --add mysql.server

   (The startup scripts directory may vary depending on your operating system and version—for example, in some Linux distributions, it is/etc/init.d.)

   Here we use Red Hat'schkconfig for creating links to the startup scripts; use whatever means is appropriate for this purpose on your platform, such asupdate-rc.d on Debian.

1. Change location to the/var/tmp directory, and extract thendbd andndbmtd binaries from the archive into a suitable directory such as/usr/local/bin:

   $> cd /var/tmp$> tar -zxvf mysql-cluster-gpl-8.0.43-linux-glibc2.12-x86_64.tar.gz$> cd mysql-cluster-gpl-8.0.43-linux-glibc2.12-x86_64$> cp bin/ndbd /usr/local/bin/ndbd$> cp bin/ndbmtd /usr/local/bin/ndbmtd

   (You can safely delete the directory created by unpacking the downloaded archive, and the files it contains, from/var/tmp oncendb_mgm andndb_mgmd have been copied to the executables directory.)

2. Change location to the directory into which you copied the files, and then make both of them executable:

   $> cd /usr/local/bin$> chmod +x ndb*

The data directory on each machine hosting a data node is/usr/local/mysql/data. This piece of information is essential when configuring the management node. (SeeSection 25.3.3, “Initial Configuration of NDB Cluster”.)

1. Change location to the/var/tmp directory, and extract thendb_mgm andndb_mgmd from the archive into a suitable directory such as/usr/local/bin:

   $> cd /var/tmp$> tar -zxvf mysql-cluster-gpl-8.0.43-linux-glibc2.12-x86_64.tar.gz$> cd mysql-cluster-gpl-8.0.43-linux-glibc2.12-x86_64$> cp bin/ndb_mgm* /usr/local/bin

   (You can safely delete the directory created by unpacking the downloaded archive, and the files it contains, from/var/tmp oncendb_mgm andndb_mgmd have been copied to the executables directory.)

2. Change location to the directory into which you copied the files, and then make both of them executable:

   $> cd /usr/local/bin$> chmod +x ndb_mgm*
