怎么使用MySQL bingol

這篇文章主要講解了“怎么使用MySQL bingol”，文中的講解內(nèi)容簡(jiǎn)單清晰，易于學(xué)習(xí)與理解，下面請(qǐng)大家跟著小編的思路慢慢深入，一起來研究和學(xué)習(xí)“怎么使用MySQL bingol”吧！

1、binlog備份

[mysql@mysql5 binlog]$mysqlbinlog --read-from-remote-server --raw --host=192.168.1.210 --port=65535 --user=yang --password=oracle --stop-never --result-file=/mysqldb/backup/backup_192.168.1.210/binlog/ master-bin.000001

2、解析binlog

[mysql@mysql5 binlog]$ mysqlbinlog -v -v -v master-bin.000007 > 07.txt

[mysql@mysql5 binlog]$ vi 07.txt

/*!50530 SET @@SESSION.PSEUDO_SLAVE_MODE=1*/;

/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;

DELIMITER /*!*/;

3、binlog恢復(fù)

[mysql@mysql5 binlog]$  mysqlbinlog --start-position=161899 --stop-position=323048 --skip-gtids /mysqldb/db_slave/binlog/slave-bin.000001|mysql -uroot -p -S/mysqldb/db_test01/mysql.sock employees

實(shí)驗(yàn)

1、導(dǎo)入employees數(shù)據(jù)庫(kù)

2、創(chuàng)建表

mysql> create table test1 like dept_emp;

Query OK, 0 rows affected (0.85 sec)

mysql> alter table test1 drop primary key;

Query OK, 0 rows affected (0.31 sec)

Records: 0  Duplicates: 0  Warnings: 0

mysql> insert into test1 select * from dept_emp limit 10000;

Query OK, 10000 rows affected (0.16 sec)

Records: 10000  Duplicates: 0  Warnings: 0

3、mysqldump備份employees數(shù)據(jù)庫(kù)

[mysql@mysql5 db_slave]$ mysqldump -uroot -p -S/mysqldb/db_slave/mysql.sock --master-data=2 --single-transaction --databases employees --set-gtid-purged=off > testdump.sql

Enter password:

4、模擬業(yè)務(wù)

mysql> insert into test1 select * from dept_emp limit 10000;

Query OK, 10000 rows affected (0.50 sec)

Records: 10000  Duplicates: 0  Warnings: 0

mysql> delete from test1 limit 1000;

Query OK, 1000 rows affected (0.30 sec)

mysql> create table test2 like dept_emp;

Query OK, 0 rows affected (0.27 sec)

5、發(fā)現(xiàn)問題進(jìn)行回滾

MASTER_LOG_POS=161899

at 323048

[mysql@mysql5 binlog]$ mysqlbinlog -v -v -v slave-bin.000001 > 1.txt

[mysql@mysql5 binlog]$ vi 1.txt

[mysql@mysql5 db_slave]$ vi testdump.sql

mysql> source /mysqldb/db_slave/testdump.sql #空實(shí)例中#

[mysql@mysql5 binlog]$  mysqlbinlog --start-position=161899 --stop-position=323048 --skip-gtids /mysqldb/db_slave/binlog/slave-bin.000001|mysql -uroot -p -S/mysqldb/db_test01/mysql.sock employees

5、結(jié)果

6、導(dǎo)入刪除數(shù)據(jù)

[mysql@mysql5 ~]$ mysqldump -uroot -p -S /mysqldb/db_test01/mysql.sock employees test1 --where="1=1 limit 1000;" --set-gtid-purged=OFF > test3.sql

Enter password:

[mysql@mysql5 ~]$ vi test3.sql

[mysql@mysql5 ~]$ mysql -uroot -p -S /mysqldb/db_slave/mysql.sock --database=employees --table=test1 < test3.sql

mysql: [Warning] mysql: ignoring option '--table' due to invalid value 'test1'
