New mysql55-mysql packages are now available for Red Hat Enterprise Linux 5. MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon and many client programs and libraries. The mysql55-mysql package, provided as a Software Collection, contains MySQL version 5.5. Software Collections allow users to install and use multiple versions of the same package in one system. Software Collection packages are installed into an alternate directory. For more information about the changes included in MySQL 5.5, refer to the release notes linked to in the References section. This enhancement update adds the mysql55-mysql packages to Red Hat Enterprise Linux 5. These packages include only the server part of MySQL 5.5; they do not include a client C library. A client C library that is a part of the core Red Hat Enterprise Linux 5 system is expected to be used to connect to the MySQL 5.5 server. Note: for more information on the migration from MySQL 5.0 to MySQL 5.5, refer to chapter &qt Migrating from MySQL 5.0 to MySQL 5.5 &qt in the &qt Red Hat Enterprise Linux 5 Deployment Guide &qt at https://access.redhat.com/site/documentation/Red_Hat_Enterprise_Linux/. Note: Red Hat will not issue any more security advisories for the MySQL 5.0 packages . Security advisories will be provided only for MySQL 5.5. All users who require mysql55-mysql are advised to install these new packages.
