In this issue, Xiaobian will bring you about how to backup data in mysqldump. The article is rich in content and analyzes and narrates from a professional perspective. After reading this article, I hope you can gain something.
Use mysqldump
Export a library to a SQL file
mysqldump db_name > /path/name.sql -uroot -p
If database is too large, compress export
mysqldump db_name | gzip > /path/name.sql -u root -p[@more@]
Backup all libraries
mysqldump --all-databases > /path/name.sql -u root -p
mysqldump --all-databases | gzip > /path/name.gz -uroot -p
Backup a single table or several tables
mysqldump db_name tab_name > /path/sqlname.sql -u root -p
Recover Data Import Data
mysql db_name
< backup-file.sql -u root -p 有一种用mysql db_name < backup-file.sql -u root -p ………………………………………………………… 添加mysql用户mysqlname 密码为password ,赋予dbname数据库所有权限 mysql>grant all on dbname.* to mysqlname@localhost identified by 'password';
mysql > grant select,insert,update,delete,create,drop on database name.* to user (new)@localhost identified by 'password';
Or modify the mysql table directly
mysql > insert into user(host,user,password) values('%','user_name',password("you password"));
mysql > set password for user_name=password("you_password")
The above two must be overloaded authorization table (./ scripts/mysql_install_db)
Or in a shell environment.
mysqladmin -u root password "you password"
Export a database structure
mysqldump -u wcnc -p -d --add-drop-table smgp_apps_wcnc >d:wcnc_db.sql
-d No data--add-drop-table Add a drop table before each create statement
import database
Common source command
Go to mysql database console and
as
mysql -u root -p
mysql>use database
Then use the source command, followed by a script file (such as the.sql used here)
mysql>source d:wcnc_db.sql..
