If an option or system variable is not explicitly set, then it will be set to its default value. If the -defaults-file option is set, then MariaDB will only read the option file referred to by this option. However, if the -defaults-file option is set, and if the file does not exist, then MariaDB will raise an error. For example, you could have an option file in /etc/my.cnf with global settings for all servers, and then you could another option file in ~/.my.cnf (i.e.your user account's home directory) which will specify additional settings (or override previously specified setting) that are specific only to that user. MariaDB will look in all of the above locations, in order, even if has already found an option file, and it's possible for more than one option file to exist. Note that if MARIADB_HOME is set (from MariaDB 10.6), MYSQL_HOME will not be used, even if set.MARIADB_HOME (from MariaDB 10.6) or MYSQL_HOME is the environment variable containing the path to the directory holding the server-specific my.cnf file.For example, if mysqld.exe is in C:\Program Files\ MariaDB 10.3\bin, then INSTALLDIR would be C:\Program Files\ MariaDB 10.3. INSTALLDIR is the parent directory of the directory where mysqld.exe is located.The value may be a private Windows Directory for the application, or it may be the same as the System Windows Directory returned by the GetSystemWindowsDirectory function. The Windows Directory is the directory returned by the GetWindowsDirectory function.To find its specific value on your system, open cmd.exe and execute: echo %WINDIR% The System Windows Directory is the directory returned by the GetSystemWindowsDirectory function.When the DEFAULT_SYSCONFDIR cmake option was not defined, MariaDB looks for the MariaDB option file in the following locations in the following order:įile specified with -defaults-extra-file, if any.This option is usually defined as /etc when building RPM packages, but it is usually not defined when building DEB packages or binary tarballs. The locations are dependent on whether the DEFAULT_SYSCONFDIR cmake option was defined when MariaDB was built. MariaDB looks for the MariaDB option file in the locations and orders listed below. On Linux, Unix, or Mac OS X, the default option file is called my.cnf. Default Option File Locations on Linux, Unix, Mac The effect of the configuration options are as if they would have been given as command line options in the order they are found. The option files are each scanned once, in the order given by -help -verbose. The following groups are read: mysqld server mysqld-10.3 mariadb mariadb-10.3 client-server galera Mysqld Ver 10.3.13-MariaDB-log for Linux on x86_64 (MariaDB Server)Ĭopyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.ĭefault options are read from the following files in the given order: See the sections below to find out which directories are checked for which system.įor an exact list of option files read on your system by a specific program, you can execute: $program -help -verbose MariaDB reads option files from many different directories by default. In addition to the default option groups, also read option groups with the given suffix. Read this extra option file after all other option files are read. Only read options from the given option file. Read options from option files, print all option values, and then exit the program. They must be given as the first argument on the command-line: ![]() These options can be used with most of MariaDB's command-line tools, not just mysqld. The following options relate to how MariaDB handles option files. Depending on how you've installed MariaDB, the default option file may be in a number of places, or it may not exist at all. The default MariaDB option file is called my.cnf (or mariadb.cnf) on Unix-like operating systems and my.ini on Windows. You can configure MariaDB to run the way you want by configuring the server with MariaDB's option files.
