本文主要是介绍MySQL主从复制实战,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
1、准备主从二进制与中断日志记录
mkdir -p /mysql/log/3306/binlog
mkdir -p /mysql/log/3306/relaylog
chown -R mysql:mysql /mysql/log/3306/binlog
chown -R mysql:mysql /mysql/log/3306/relaylog
chmod -R 775 /mysql/log/3306/binlog
chmod -R 775 /mysql/log/3306/relaylog
2、准备主库参数
bind-address=192.168.1.51
server_id=513306
skip_name_resolve = ON
expire_logs_days = 7
innodb_support_xa =1
binlog_cache_size = 1M
max_binlog_size = 2048M
log_bin_trust_function_creators = 1
innodb_flush_log_at_trx_commit =1
sync_binlog = 1
transaction-isolation = READ-COMMITTED
gtid_mode = ON
enforce_gtid_consistency = 1
log-slave-updates = 1
binlog_gtid_simple_recovery=1
log_bin=/mysql/log/3306/binlog/itpuxdb-binlog
log_bin_index=/mysql/log/3306/binlog/itpuxdb-binlog.index
binlog_format=ROW
binlog_rows_query_log_events=on
plugin_dir=/mysql/app/mysql/lib/plugin/
plugin_load="rpl_semi_sync_master=semisync_master.so;rpl_semi_sync_slave=semisync_slave.so"
