linux下mysql5.7.19数据库备份（增量备份恢复）

linux下mysql5.7.19数据库备份（增量备份恢复）

1.查看备份文件

mysqlbinlog  /var/lib/mysql/mysql-bin.000002 > /var/lib/mysql/tmp.sql

查看转换后的sql文件内容：

cat /var/lib/msql/tmp.sql

tmp.sql文件内容，如下：

/*!50530 SET @@SESSION.PSEUDO_SLAVE_MODE=1*/;
/*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/;
DELIMITER /*!*/;

2.还原数据的基本语句

linux系统下，还原mysql-bin.000001到数据库test_database

mysqlbinlog /var/lib/mysql/mysql-bin.000001 | mysql -uroot -p --one-database test_database
