There are a number of different ways to specify the connectstring:
• Each executable has its own command-line option which enables specifying the management server
at startup. (See the documentation for the respective executable.)
• It is also possible to set the connectstring for all nodes in the cluster at once by placing it in a
[mysql_cluster]
• For backward compatibility, two other options are available, using the same syntax:
1. Set the
2. Write the connectstring for each executable into a text file named
the executable's startup directory.
However, these are now deprecated and should not be used for new installations.
The recommended method for specifying the connectstring is to set it on the command line or in the
file for each executable.
my.cnf
The maximum length of a connectstring is 1024 characters.
