MariaDB基于GTID的复制-创新互联

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
