1,主備創建賬號

GRANT REPLICATION SLAVE,REPLICATION CLIENT ON *.*

TO rep@’172.16.0.%’ IDENTIFIED BY ‘rep’;

2,配置主庫

My.cnf

log_bin=mysql-bin

server_id=10

innodb_flush_log_at_trx_commit=1

sync_binlog=1

3,配置從庫

log_bin=mysql-bin

server_id=2

relay_log = /var/lib/mysql/mysql-relay-bin

log_slave_updates = 1

read_only =1

sync_master_info=1

sync_relay_log=1

sync_relay_log_info=1

skip-host-cache

skip-name-resolve

slave_net_timeout=30 //主備未發現連接斷開超時時間

slave_skip_errors=1062

mysql中執行

CHANGE MASTER TO MASTER_HOST=’172.16.0.129’,

MASTER_USER=’rep’,

MASTER_PASSWORD=’rep’,

MASTER_LOG_FILE=’mysql-bin.000001’,

MASTER_LOG_POS=0;

Start slave

Show slave statusG;

4,備庫提升方法

CHANGE MASTER TO MASTER_HOST=’’, //5.5以后的版本使用 RESET SLAVE ALL命令完成

RESET SLAVE
