基本的備份命令

mysqldump -h hostname -u username -p password databasename > backupfile.sql

基本還原命令

mysql -h hostname -u username -p password databasename < backupfile.sql

幫助：mysqldump --help

指定時間恢復(fù)

mysqlbinlog --start-date="2005-04-20 10:01:00" /var/log/mysql/bin.123456  | mysql -u root -pmypwd 
mysqlbinlog --stop-date="2005-04-20 10:01:00" /var/log/mysql/bin.123456  | mysql -u root -pmypwd 

指定位置恢復(fù)

mysqlbinlog --stop-position="368312" /var/log/mysql/bin.123456  | mysql -u root -pmypwd 
mysqlbinlog --start-position="368312" /var/log/mysql/bin.123456  | mysql -u root -pmypwd 

根據(jù)數(shù)據(jù)庫名來進行還原 -d
在這里是小寫的d，請不要把它和mysqldump中的－D搞混了。

[root@BlackGhost mysql]# /usr/local/mysql/bin/mysqlbinlog -d test  /var/lib/mysql/mysql-bin.000002

根據(jù)數(shù)據(jù)庫所在IP來分－h(huán)

[root@BlackGhost mysql]# /usr/local/mysql/bin/mysqlbinlog -h 192.1681.102  /var/lib/mysql/mysql-bin.000002

根據(jù)數(shù)據(jù)庫所占用的端口來分－P
有的時候，我們的mysql用的不一定是3306端口，注意是大寫的P

[root@BlackGhost mysql]# /usr/local/mysql/bin/mysqlbinlog -P 13306  /var/lib/mysql/mysql-bin.000002

根據(jù)數(shù)據(jù)庫serverid來還原–server-id
在數(shù)據(jù)庫的配置文件中，都有一個serverid并且同一集群中serverid是不能相同的。

[root@BlackGhost mysql]# /usr/local/mysql/bin/mysqlbinlog –server-id=1  /var/lib/mysql/mysql-bin.000002

備份所有數(shù)據(jù)，并清空所有bin-log日志

./mysqldump –flush-logs -u root  –all-databases > /tmp/alldatabase.sql
