Add MySQL 5.6 from node Slave

MySQL version: 5.6.36
Xtraback Edition: Version 2.4.6

1. Modify the master node MySQL configuration file and restart 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. Use Xtrabackup to fully prepare MySQL and copy the backup set to the slave node
Innobackupex--defaults-file=/usr/local/mysql/my.cnf--slave-info--user=root [email PROTECTED]%ACD--socket=/tmp/ Mysql.sock/root

3. Modify the MySQL configuration file from the node and restart 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 = ten

Sql_mode=no_engine_substitution,strict_trans_tables

4. Recovering a database from a node using Xtrabackup
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. Create a copy dedicated account on the master node
Mysql> GRANT REPLICATION SLAVE on * * to ' repluser ' @ ' 10.10.45.155 ' identified by ' 123456 ';
mysql> flush Privileges;

6. View slave copy information
Cat/var/lib/mysql/xtrabackup_binlog_pos_innodb
mysql-bin.000003 124800463

7. Add from node to master node
mysql> Change Master to master_host= ' 10.10.45.154 ', master_port=3306,master_user= ' repluser ', master_password= ' [ Email PROTECTED]%ACD ', master_log_file= ' mysql-bin.000003 ', master_log_pos=124800463;
mysql> start slave;
Mysql> show Slave status\g;
