6. Verify after upgrade
mysqldump commonly used in the MySQL database logical backup
1. The simplest usage:
mysqldump -uroot -pPassword [database name] > [dump file]
Above the specified database backup command to a file dump (dump), such as:
mysqldump -uroot -p123 test > test.dump
Test.dump resulting file contains the statement build table (database structure generating Oh) and insert data insert statements.
2. --opt
If --opt parameters plus the resulting dump file is slightly different:
- Construction of the table statement contains a drop table if exists tableName
- insert includes a lock table statement before the lock tables tableName write, then insert contained unlock tables
3. Cross-host backup
Use the following command to copy sourceDb on host1 to host2 of targetDb, provided that the database has been created targetDb host host2:
mysqldump --host=host1 --opt sourceDb| mysql --host=host2 -C targetDb
- -C data indicating the data transfer between the host using compression
4. Only the backup table structure
mysqldump --no-data --databases mydatabase1 mydatabase2 mydatabase3 > test.dump
Backs up only the table structure. --databases instruct the database on the host computer to back up. If you want to back up all of a MySQL database on the host can use the --all-databases option, as follows:
mysqldump --all-databases > test.dump
5. Restore the database from a backup file
mysql [database name] < [backup file name]

6. Verify after upgrade
mysqldump commonly used in the MySQL database logical backup
1. The simplest usage:
mysqldump -uroot -pPassword [database name] > [dump file]
Above the specified database backup command to a file dump (dump), such as:
mysqldump -uroot -p123 test > test.dump
生成的test.dump文件中包含建表语句（生成数据库结构哦）和插入数据的insert语句。
2. --opt
如果加上--opt参数则生成的dump文件中稍有不同：
- 建表语句包含drop table if exists tableName
- insert之前包含一个锁表语句lock tables tableName write，insert之后包含unlock tables
3. 跨主机备份
使用下面的命令可以将host1上的sourceDb复制到host2的targetDb，前提是host2主机上已经创建targetDb数据库：
mysqldump --host=host1 --opt sourceDb| mysql --host=host2 -C targetDb
- -C指示主机间的数据传输使用数据压缩
4. 只备份表结构
mysqldump --no-data --databases mydatabase1 mydatabase2 mydatabase3 > test.dump
将只备份表结构。--databases指示主机上要备份的数据库。如果要备份某个MySQL主机上的所有数据库可以使用--all-databases选项，如下：
mysqldump --all-databases > test.dump
5. 从备份文件恢复数据库
mysql [database name] < [backup file name]
