For small databases, we can directly use the mysqldump full library export import to create a slave library.

Test environment:

CentOS6.8 x86_64

MySQL5.6.34 Community rpm Edition

Main library: node0 192.168.2.10

Slave library: node1 192.168.2.11

5.6.The parameters required for GTID replication (these three lines of parameters should be added for both master and slave libraries):

Gtid-mode=ON

Enforce_gtid_consistency = ON

Log_slave_updates=ON

Step1, export in the main library and scp transfer to node1:

Mysqldump-uroot-pwww.Mwbyd91@-A-Q-- single-transaction-- master-data=2 > / root/all.sql

Scp / root/all.sql node1:/root/

Step2, restore on node1:

Node1 newly installed does not have a password, execute mysql to log in

Source / root/all.sql

"step3, start replication on node1:"

CHANGE MASTER TO MASTER_HOST='192.168.2.10'

MASTER_USER='rpl'

MASTER_PASSWORD='rpl'

MASTER_PORT=3306

MASTER_AUTO_POSITION=1

Start slave

Show slave status\ G

Importing mysqldump in this way does not require operations like set global gtid_purged='xxxxx'; to be performed by innobackup. Because there are automatic settings in the sql exported by mysqldump. For example, the following figure is a partial screenshot of the exported all.sql:
