For most applications, you want to set this as either InnoDB or MyISAM. With this variable, we change the default storage engine type. If you recall from previous chapters, we mentioned that CREATE TABLE command defaults to the MyISAM storage engine. The next line is the "default-storage-engine" variable and value. If you change the location, you must be sure that the data moves with it. It's the basic root of the database, and any changes to this value should be done with care. This is the directory that tells the database where to find all data files. If you change this directory accidentally, it can have serious affects on your database application. If you move your MySQL installation location, then you would change this value. It's also the location of critical system files. Any additional installation components use this directory, so always keep installation files within this directory structure. This is the installation location for the service. Knowing the database runs on a Windows server helps you troubleshoot issues if you are unable to resolve any configuration specific problems.įirst, you have the "basedir" variable. As you might observe, the database system is on a Windows server by the format of the storage directories. You could have several other options in the file, but we're covering a few of the major, common ones. Here is an example configuration section for mysqld.īasedir="C:/Program Files/MySQL/MySQL Server 5.5/"ĭatadir="C:/Documents and Settings/All Users/Application Data/MySQL/MySQL Server 5.5/Data/" This section has service specific configurations set for the database server. Now let's look at a longer section named. When you hear a database administrator refer to this port, they often say that the server is "listening" on this port. In this example, the administrator set port 3306 as the MySQL client connection port, which opens this port for database connections. Of course, it's not a guarantee that all hackers will never scan non-standard ports, but moving the database services to a non-standard port avoid database discovery for non-specific hacks. The reason they do this is to avoid discovery of the database server from port scanners. When hackers scan ports for services, they scan standard ports. For security purposes, some MySQL administrators use a non-standard port for MySQL server connections. The port is where client applications connect. This section has one variable named port. ![]() Let's take a look at the typical client section. If you don't set the configuration, MySQL will use its own default value. The configuration is the MySQL specific variable that you can set. The format is "configuration = value" where value is your configuration value. The section is set for client applications. For instance, the section has server specific configurations. The options file has several sections marked in brackets. You can open the ini files with any text editor. Right-click the MySQL service and select "Properties." In the executable path, it displays where the my.ini file is located. Open Services from the Control Panel Administrative Options section. With Windows, you don't need to search through directories to find option files. Server specific options are stored in the $MYSQL_HOME directory, and user specific configurations are stored in ~/ where ~/ is the user's home directory. For Linux and Unix, the file is stored in the /etc/ or SYSCONFDIR directory for global options. We'll discuss a few of the major configurations that each database administrator should know.įirst, you need to know where the file is located. For new MySQL server installations, it's small and grows as you continue to add more preferences. ![]() The MySQL options file can be short or several lines of preferences, depending on the number of configurations you've set. This article discusses performance tuning and configurations for your MySQL server and its databases. Performance drives profitability and productivity for a corporation, so you must fine tune your MySQL database for optimal performance. Server performance is paramount for a stable application. With these configurations, you need to think about server performance. Your configurations are saved in an option file, which is also referred to as a configuration file. Fortunately, you don't need to configure MySQL every time you restart it. After you install MySQL, you need to configure it.
