Support #380
Updated by Daniel Curtis over 9 years ago
This guide a is to show how to build MariaDB with WSREP and Galera for a Multi-Master SQL database cluster. It is assumed that a FreeNAS jail has been setup as per Issue #329 and root access has been obtained. * Update the ports tree: <pre> portsnap fetch extract </pre> * Once that is done, build mariadb55-server from the ports tree. This is to resolve the source dependencies for recompiling the MariaDB server later on with wsrep. <pre> cd /usr/ports/databases/mariadb55-server make install clean </pre> * Now uninstall MariaDB server: <pre> make deinstall clean </pre> * And now resolve a few dependencies before compiling the new MariaDB server: <pre> pkg install bzr bison boost-all scons libcheck cmake </pre> * Install the check unit testing framework: <pre> mkdir /usr/local/src/ cd /usr/local/src wget http://sourceforge.net/projects/check/files/latest/download mv download check.tar.gz tar xzf check.tar.gz cd check-* ./configure make make install cd .. </pre> h2. Download and compile MariaDB with wsrep * Download the latest MariaDB from launchpad <pre> cd /usr/src bzr branch lp:~maria-captains/maria/maria-5.5-galera maria-5.5-galera </pre> * Compile MariaDB with wsrep: <pre> cd maria-5.5-galera cmake . -DBUILD_CONFIG=mysql_release -DWITH_WSREP=ON -DWITH_INNODB_DISALLOW_WRITES=1 make make install cd .. </pre> h2. Download and compile Galera * Install Galera from the ports tree (recommended) <pre> cd /usr/ports/databases/galera make install clean </pre> #* Or install from the developers tree: <pre> bzr branch lp:galera/2.x galera-2.x cd galera-2.x scons </pre> * Copy the boot mariadb boot script <pre> cd /usr/local/mysql/support-files/ cp /usr/local/mysql/support-files/mysql.server mysql.server /usr/local/etc/rc.d/mysql.server.sh </pre> *# The boot script also needs to be edited, like the following example: <pre> vi /usr/local/etc/rc.d/mysql.server.sh </pre> #* And modify the two configuration parameters: <pre> > basedir=/usr/local/mysql > datadir=/usr/local/mysql/data </pre> * Initialize and secure the MariaDB database <pre> cd /usr/local/mysql /usr/local/mysql/scripts/mysql_install_db chown -R mysql:mysql data/ </pre> * Configure the new cluster: <pre> vi /usr/local/etc/mysql/conf.d/cluster.cnf </pre> #* And add the following: <pre> [mysqld] binlog_format=ROW default-storage-engine=innodb innodb_autoinc_lock_mode=2 bind-address=0.0.0.0 # Galera Provider Configuration wsrep_provider=/usr/lib/galera/libgalera_smm.so #wsrep_provider_options="gcache.size=32G" # Galera Cluster Configuration wsrep_cluster_name="example_cluster" # Initialize the cluster; switch after --wsrep-new-cluster has been run and other nodes have joined. wsrep_cluster_address="gcomm:// # Set cluster node addresses (hostnames work too) #wsrep_cluster_address="gcomm://192.168.0.1,192.168.0.2,192.168.0.3" # Galera Synchronization Configuration wsrep_sst_method=rsync #wsrep_sst_auth=user:pass # Galera Node Configuration wsrep_node_address="192.168.0.1" wsrep_node_name="db1.example.com" </pre> * Bootstrap the new Galera cluster <pre> service mysql.server.sh bootstrap </pre> *# The alternate way to bootstrap the cluster is like so: <pre> /usr/local/mysql/bin/mysqld --user=mysql --wsrep-new-cluster </pre> * Now in a second terminal connection run the @mysql_secure_installation@ script to do some post-installation hardening: <pre> /usr/local/mysql/bin/mysql_secure_installation </pre> By this point MariaDB should be able to be controlled by the service command: <pre> service mysql.server.sh stop service mysql.server.sh start </pre> h2.
