1.備份MySQL數(shù)據(jù)庫(kù)的命令

mysqldump -hhostname -uusername -ppassword databasename > backupfile.sql

2.備份MySQL數(shù)據(jù)庫(kù)為帶刪除表的格式，能夠讓該備份覆蓋已有數(shù)據(jù)庫(kù)而不需要手動(dòng)刪除原有數(shù)據(jù)庫(kù)。

mysqldump -–add-drop-table -uusername -ppassword databasename > backupfile.sql

3.直接將MySQL數(shù)據(jù)庫(kù)壓縮備份

mysqldump -hhostname -uusername -ppassword databasename | gzip > backupfile.sql.gz

4.備份MySQL數(shù)據(jù)庫(kù)某個(gè)(些)表

mysqldump -hhostname -uusername -ppassword databasename specific_table1 specific_table2 > backupfile.sql

5.同時(shí)備份多個(gè)MySQL數(shù)據(jù)庫(kù)

mysqldump -hhostname -uusername -ppassword –databases databasename1 databasename2 databasename3 > multibackupfile.sql

6.僅僅備份數(shù)據(jù)庫(kù)結(jié)構(gòu)

mysqldump –no-data –databases databasename1 databasename2 databasename3 > structurebackupfile.sql

7.備份服務(wù)器上所有數(shù)據(jù)庫(kù)

mysqldump –all-databases > allbackupfile.sql

8.還原MySQL數(shù)據(jù)庫(kù)的命令

mysql -hhostname -uusername -ppassword databasename < backupfile.sql

9.還原壓縮的MySQL數(shù)據(jù)庫(kù)

gunzip < backupfile.sql.gz | mysql -uusername -ppassword databasename

10.將數(shù)據(jù)庫(kù)轉(zhuǎn)移到新服務(wù)器

mysqldump -uusername -ppassword databasename | mysql –host=*.*.*.* -C databasename
