1、使用mysqldump搭建基於GTID的從庫

A庫--3306埠

B庫--3307埠

C庫--3308埠

現有mysql架構：基於GTID的A-B
mysqldump B庫
/usr/local/mysql/bin/mysqldump  --master-data=2 --single-transaction -A -h127.0.0.1 -uroot -proot -P3307 > 3307.sql 
3307.sql中有如下資訊：
SET @@GLOBAL.GTID_PURGED='65dfb885-05ff-11e6-b9f7-080027275cb7:1,  --B的GTID資訊
babb81f3-e8c4-11e5-bb5e-080027d6e4e2:1-3047';   --A的GTID資訊
C庫匯入
[
 
[email protected] db_bak]mysql -uroot -proot -h127.0.0.1 -P3308 < 3307.sql 
ERROR 1840 (HY000) at line 24: @@GLOBAL.GTID_PURGED can only be set when @@GLOBAL.GTID_EXECUTED is empty.
此時C庫執行：
reset master;
然後匯入
C庫執行
CHANGE MASTER TO MASTER_HOST='192.168.56.159',
				 MASTER_PORT=3306,
				 MASTER_USER='repl',
				 MASTER_PASSWORD='repl',
				 master_auto_position=1;
OK
 

現有mysql架構：基於GTID的A-B
使用innobackup備份B庫
/usr/bin/innobackupex-1.5.1 --defaults-file=/data/mysql/mysql3307/my3307.cnf --user=root --password=root --host=127.0.0.1 --port=3307  --slave-info  --no-timestamp  /data/mysqlbak/db_bak/db3307

恢復還原到C庫
/usr/bin/innobackupex-1.5.1 --user=root --host=127.0.0.1 --port=3308 --defaults-file=/data/mysql/mysql3308/my3308.cnf --apply-log /data/mysqlbak/db_bak/db3307		
/usr/bin/innobackupex-1.5.1 --user=root --host=127.0.0.1 --port=3308 --defaults-file=/data/mysql/mysql3308/my3308.cnf --copy-back /data/mysqlbak/db_bak/db3307	

在備份目錄/data/mysqlbak/db_bak/db3307	檢視主的GTID位置

babb81f3-e8c4-11e5-bb5e-080027d6e4e2:1-3049

在恢復的庫上執行
set global gtid_purged='65dfb885-05ff-11e6-b9f7-080027275cb7:1,babb81f3-e8c4-11e5-bb5e-080027d6e4e2:1-3049';

CHANGE MASTER TO MASTER_HOST='192.168.56.159',
				 MASTER_PORT=3307,
				 MASTER_USER='repl',
				 MASTER_PASSWORD='repl',
				 master_auto_position=1;
start slave；

檢視binlog檔案內容

/usr/local/mysql/bin/mysqlbinlog -v --base64-output=decode-rows mysql-bin.000019 > 1.log
