mysql版本：5.6.36
xtraback版本：version 2.4.6
1、修改主节点MySQL配置文件，并重启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全备MySQL，并将备份集拷贝到从节点
innobackupex --defaults-file=/usr/local/mysql/my.cnf --slave-info --user=root --password=mg@Xa9382cs%acd --socket=/tmp/mysql.sock /root
3、修改从节点MySQL配置文件，并重启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、在从节点使用xtrabackup恢复数据库
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、在主节点创建复制专用账号
mysql> GRANT REPLICATION SLAVE ON *.* TO ‘repluser‘@‘10.10.45.155‘ IDENTIFIED BY ‘123456‘;
mysql> flush privileges;
6、查看slave复制信息
cat /var/lib/mysql/xtrabackup_binlog_pos_innodb
mysql-bin.000003 124800463
7、将从节点添加到主节点中
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;
