MySQL5.7多源复制
MySQL5.7开始支持多源复制,也就是多主一从的复制架构:
#GTID
gtid-mode = on
binlog_gtid_simple_recovery=1
enforce_gtid_consistency=1
binlog_format = row
skip_slave_start = 1
log-bin = /data/mysql/mysql_3307/logs/binlog/mysql-bin
#binlog

log-bin = /data/mysql/mysql_3307/logs/binlog/mysql-bin
#GTID
gtid-mode = on
binlog_gtid_simple_recovery=1
enforce_gtid_consistency=1
#修改MySQL存储master-info和relay-info的方式,即从文件存储改为表存储
master_info_repository=TABLE
relay_log_info_repository=TABLE
replicate_ignore_db=mysql #忽略mysql库的同步
skip_slave_start = 1
