mysql版本：5.6.36

xtraback版本：version 2.4.6

1、修改主節點MySQL配置文件，并重啟MySQL

cat /usr/local/mysql/my.cnf

[mysqld]

datadir = /var/lib/mysql

socket = /tmp/mysql.sock

binlog-format=ROW

log-slave-updates=true

gtid-mode=on

enforce-gtid-consistency=true

log-bin=mysql-bin

expire_logs_days=2

master-info-repository=TABLE

relay-log-info-repository=TABLE

sync-master-info=1

slave-parallel-workers=2

binlog-checksum=CRC32

master-verify-checksum=1

slave-sql-verify-checksum=1

binlog-rows-query-log_events=1

report-port=3306

port=3306

server_id = 1

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

2、使用xtrabackup全備MySQL，并將備份集拷貝到從節點

innobackupex --defaults-file=/usr/local/mysql/my.cnf --slave-info --user=root --password=mg@Xa9382cs%acd --socket=/tmp/mysql.sock /root

3、修改從節點MySQL配置文件，并重啟MySQL

cat /usr/local/mysql/my.cnf

[mysqld]

datadir = /var/lib/mysql

socket = /tmp/mysql.sock

relay-log = relay-log

relay-log-index = relay-log.index

binlog-format=ROW

log-bin=mysql-bin

log-slave-updates=true

gtid-mode=on

enforce-gtid-consistency=true

master-info-repository=TABLE

relay-log-info-repository=TABLE

sync-master-info=1

slave-parallel-workers=2

binlog-checksum=CRC32

master-verify-checksum=1

slave-sql-verify-checksum=1

binlog-rows-query-log_events=1

report-port=3306

port=3306

server_id = 10

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

4、在從節點使用xtrabackup恢復數據庫

innobackupex --defautls-file=/usr/local/mysql/my.cnf --apply-log --redo-only /root/2017-07-10_16-54-29

innobackupex --defautls-file=/usr/local/mysql/my.cnf --apply-log /root/2017-07-10_16-54-29

innobackupex --defautls-file=/usr/local/mysql/my.cnf --socket=/tmp/mysql.sock --copy-back /root/2017-07-10_16-54-29

5、在主節點創建復制專用賬號

mysql> GRANT REPLICATION SLAVE ON *.* TO 'repluser'@'10.10.45.155' IDENTIFIED BY '123456';

mysql> flush privileges;

6、查看slave復制信息cat /var/lib/mysql/xtrabackup_binlog_pos_innodb ?mysql-bin.000003?124800463?7、將從節點添加到主節點中mysql> change master to master_host='10.10.45.154', master_port=3306,master_user='repluser',master_password='mg@Xa9382cs%acd',master_log_file='mysql-bin.000003',master_log_pos=124800463;mysql> start slave;mysql> show slave status\G;*************************** 1. row ***************************??????????????
