添加MySQL 5.6 从节点 Slave

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;
