However, in case you choose this method, then # start replication for the first time (even unsuccessfully, for example # if you mistyped the password in master-password and the slave fails to # connect), the slave will create a master.info file, and any later # change in this file to the variables' values below will be ignored and # overridden by the content of the master.info file, unless you shutdown # the slave server, delete master.info and restart the slaver server. # For that reason, you may want to leave the lines below untouched # (commented) and instead use CHANGE MASTER TO (see above) # # required unique id between 2 and 2^32 - 1 # (and different from the master) # defaults to 2 if master-host is set # but will not function as a slave if omitted #server-id = 2 # # The replication master for this slave - required #master-host = # # The username the slave will use for authentication when connecting # to the master - required #master-user = # # The password the slave will authenticate with when connecting to # the master - required #master-password = # # The port the master is listening on. # optional - defaults to 3306 #master-port = # # binary logging - not required for slaves, but recommended #log-bin=mysql-bin # Uncomment the following if you are using InnoDB tables ##innodb_data_home_dir = //opt/app/mysql/data ##innodb_data_file_path = ibdata1:20M:autoextend:max:32G ##innodb_log_group_home_dir = //opt/app/mysql/iblogs # You can set .._buffer_pool_size up to 50 - 80 % # of RAM but beware of setting memory usage too high #innodb_buffer_pool_size = 6380M #innodb_additional_mem_pool_size = 2M # Set .._log_file_size to 25 % of buffer pool size innodb_log_file_size = 150M innodb_log_files_in_group = 3 innodb_log_buffer_size = 8M #innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 50 innodb_autoextend_increment = 100 expire_logs_days = 8 open_files_limit = 2000 transaction-isolation=READ-COMMITTED ####### Galera parameters ####### ## Galera Provider configuration wsrep_provider=/usr/lib/galera/libgalera_smm.so wsrep_provider_options="gcache.size=2G; gcache.page_size=1G" ## Galera Cluster configuration wsrep_cluster_name="MSO-automated-tests-cluster" wsrep_cluster_address="gcomm://" #wsrep_cluster_address="gcomm://mariadb1,mariadb2,mariadb3" ##wsrep_cluster_address="gcomm://192.169.3.184,192.169.3.185,192.169.3.186" ## Galera Synchronization configuration wsrep_sst_method=rsync #wsrep_sst_method=xtrabackup-v2 #wsrep_sst_auth="sstuser:Mon#2o!6" ## Galera Node configuration wsrep_node_name="mariadb1" ##wsrep_node_address="192.169.3.184" wsrep_on=ON ## Status notification #wsrep_notify_cmd=/opt/app/mysql/bin/wsrep_notify ####### [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [myisamchk] key_buffer_size = 20971520 ##[mysqlhotcopy] ##interactive-timeout ##[mysqld_safe] ##malloc-lib=//opt/app/mysql/local/lib/libjemalloc.so.1 ##log-error=//opt/app/mysql/log/mysqld.log general_log_file = /var/log/mysql/mysql.log general_log = 1
