Codership is pleased to announce a new release of Galera Cluster for MySQL consisting of MySQL-wsrep 5.5.62 and wsrep API version 25. This release incorporates all changes up to MySQL 5.5.62. Galera Cluster 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 source repositories and bug tracking are now on http://www.github.com/codership. Note that Galera Cluster for MySQL 5.5.62 will be the last release of 5.5 series. Notable bug fixes in MySQL-wsrep: * Maximum variable length was increased to 4096 in order to work around wsrep_provider_options truncation if the provider options string contains long variable values (mysql-wsrep#348). 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 or BSD 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.
