MariaDB基于GTID的复制
1、配置主从节点的服务配置文件
1.1、配置master节点：
#binlog_format=mixed
binlog-format=ROW
# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id = 1
log-slave-updates=true
master-info-repository=TABLE
relay-log-info-repository=TABLE
sync-master-info=1
slave-parallel-threads=2
binlog-checksum=CRC32
master-verify-checksum=1
slave-sql-verify-checksum=1
binlog-rows-query-log_events=1
report-port=3306
report-host=www.pancou.com
1.2、配置slave节点：
[mysqld]
#binlog_format=mixed
binlog-format=ROW
# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id = 2
log-slave-updates=true
master-info-repository=TABLE
relay-log-info-repository=TABLE
sync-master-info=1
slave-parallel-threads=2
binlog-checksum=CRC32
master-verify-checksum=1
slave-sql-verify-checksum=1
binlog-rows-query-log_events=1
report-port=3306
report-host=www.pancou.com
