Codership is pleased to announce the release of Galera Replication library 3.27, implementing wsrep API version 25. The library is now available as targeted packages and package repositories for a number of Linux distributions, including Ubuntu, Debian, CentOS, RHEL, OpenSUSE and SLES. Obtaining packages using a package repository removes the need to download individual files and facilitates the deployment and upgrade of Galera nodes. This and future releases will be available from http://www.galeracluster.com. The latest version of Galera for FreeBSD is available in the FreeBSD Ports Collection. New features and notable fixes in Galera replication since last binary release by Codership (3.26): * Prevent protocol downgrade on rolling upgrade (codership/galera#537) * Fixed GCache page store bus error on NVMFS End of Life: * This is the last release for SuSE Linux Enterprise Server 11 Reminder: Changes to Repositories Structure =========================================== With the new release the repository structure is changed to allow for existence of all of the wsrep-patched mysql versions currently supported: 5.5 through 5.7. Thus the repository layout requires from the user to adjust his or her repository configuration to accomodate those changes. In order to have the WSREP and Galera library installed, one would need to add the following repositories: 1. Galera-3 repository for galera library: e.g. http://releases.galeracluster.com/galera-3// 2. Corresponding mysql-wsrep repository: e.g. http://releases.galeracluster.com/mysql-wsrep-/ here: *ldist* is Linux distribution (Ubuntu, Centos, ...) and *mversion* is MySQL version, i.e. 5.5, 5.6, 5.7 How To Install -------------- Repositories contain dummy or meta packages, called mysql-wsrep- which are convenience packages for installation of the corresponding version of WSREP. One can install the whole suite by running, for example: `apt-get install mysql-wsrep-5.6 galera-3` #### Quirks for Ubuntu Xenial and 5.6 Due to the peculiarities of how apt resolves packages and presence of 5.7 libraries in Xenial repositories the command above might require additional steps/changes in order to succeed. One would need to either configure apt pinning for codership repositories for them to have priority over upstream packages or to specify mysql-common package version explicitly as the one located in the WSREP repositories in order to get things installed.
