1.主庫的復制用戶密碼修改后，在備庫修改復制：

stop slave;

change master to master_user=‘username‘, master_password=‘password‘;

start slave;

2.創建復制子用戶及其授權：

GRANT REPLICATION SLAVE, REPLICATION CLIENT ON . TO ‘repl‘@‘%‘;

alter user ‘repl‘@‘%‘ identified by "password";

3.關于復制的一些參數：

slave-parallel-type = LOGICAL_CLOCK

slave-parallel-workers = 20

master_info_repository = TABLE

relay_log_info_repository = TABLE

relay_log_recovery = ON

skip-slave-start = 0

relay-log = /data/mysql/data/relay-bin

slave-net-timeout = 60

sync-master-info = 0

sync-relay-log = 0

sync-relay-log-info = 0

read_only = 1

#rpl_semi_sync_master_enabled=1

#rpl_semi_sync_master_timeout=10000# 10 second

#rpl_semi_sync_slave_enabled=1
