![]() Strongly recommended for production servers. Which will also give you the option of removing the testĭatabases and anonymous user created by default. usr/bin/mysqladmin -u root -h medica2 password 'new-password' usr/bin/mysqladmin -u root password 'new-password' To do so, start the server, then issue the following commands: PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! This will also display the following output and start the MySQL daemon automatically. # ġ:MySQL-client-community # Ģ:MySQL-server-community # # rpm -ivh MySQL-server-community-5.1. MySQL-client-community-5.1. Install the MySQL Server and Client packages as shown below. Warning: /etc/my.cnf saved as /etc/my.cnf.rpmsave Remove the existing default MySQL that came with the Linux distroĭo not perform this on an system where the MySQL database is getting used by some application. Make sure to download MySQL Server, Client and “Headers and libraries” from the download page. I downloaded the “Red Hat Enterprise Linux 5 RPM (x86)”. Please download the community edition of MySQL for your appropriate Linux platform. Download the latest stable relase of MySQLĭownload mySQL from. ![]() In this article, I will explain how to install the latest free community edition of MySQL on Linux platform. Later you can upgrade it to the latest version when it becomes available. If you want use MySQL, my recommendation is that you download the latest version of MySQL and install it yourself. MySQL Community Server 5.5.Most of the Linux distro comes with MySQL. * Upgrades using an RPM package recreated the test database, which is undesirable when the DBA had removed it. ON DUPLICATE KEY UPDATE statements where there was a duplicated key value. * The mysql_affected_rows() C API function returned 3 (instead of 2) for INSERT. * The embedded server crashed when argc = 0. This makes it easier to perform calculations that compute differences between columns. ![]() * Previously, Performance Schema table columns that held byte counts were BIGINT UNSIGNED. * For a lower_case_table_names value of 1 or 2 and a database having a mixed-case name, calling a stored function using a fully qualified name including the database name failed. If it has been mapped with the same settings, or if the table is set to be ignored by filtering rules, there is no change in behavior: the event is skipped and IDs are not checked. Now, before applying a table map event, the server checks whether the table has already been mapped with different settings, and if so, an error is raised and the slave SQL thread stops. This was especially likely if the events mapped different tables to the same identifier, such as could happen due to Bug#56226. * Replication: Processing of corrupted table map events could cause the server to crash. Issues were reported only for the first underlying table. * CHECK TABLE and REPAIR TABLE failed to find problems with MERGE tables that had underlying tables missing or with the wrong storage engine. * A DBUG_ASSERT added by Bug #11792200 was overly aggressive in raising assertions. * With profiling disabled or not compiled in, set_thd_proc_info() unnecessarily checked file name lengths. * Compilation failed on Mac OS X 10.7 (Lion) with a warning: Implicit declaration of function 'pthread_init' For example, SELECT COUNT(*) FROM INFORMATION_SCHEMA.TRIGGERS was affected. * The metadata locking subsystem added too much overhead for INFORMATION_SCHEMA queries that were processed by opening only. Because this feature can improve performance in some cases and reduce performance in others, before relying on this setting, benchmark both with and without the setting enabled. ![]() To turn it on, enable the innodb_random_read_ahead configuration option. Because it is only helpful for certain workloads, it is turned off by default. * InnoDB Storage Engine: The “random read-ahead” feature that was removed from the InnoDB Plugin is now available again. ![]()
