mysql dba体系进修（16）mysql的mysqldump备份

 这就是dump的结果

[root@test4 Desktop]# cat /tmp/test.sql
-- MySQL dump 10.13  Distrib 5.1.70, for unknown-linux-gnu (x86_64)

由于我们dump的时候用了master-data参数，这个时候记录了日志位置和日志文件名

-- CHANGE MASTER TO MASTER_LOG_FILE='mysqlbin.000166', MASTER_LOG_POS=798;

实践之事务性一直备份（备份期间数据库可写）

mysql> use  test

mysql> create table tt(id int,name varchar(12)) engine=innodb ;

Query OK, 0 rows affected (0.11 sec)

mysql> insert into tt values(1,'zz');

Query OK, 1 row affected (0.01 sec)

mysql> insert into tt values(2,'yy');

Query OK, 1 row affected (0.00 sec)

[root@test4 Desktop]# mysqldump  --databases test  --skip-opt --quick --extended-insert=false  --single-transaction   --master-data=2  -u root -p123456 >  /tmp/test.sql
