The following mainly brings you the method of creating a full backup of Mysql database. I hope these words can bring you practical use, which is also the main purpose of this article that I edit Mysql database to create a full backup method. All right, don't talk too much nonsense, let's just read the following.
The first backup method:
Backup using tar packaged folders
Make a compressed backup of the database file directory data, using the xz format with high compression ratio
[root@localhost opt] # yum install-y xz
[root@localhost opt] # tar jcvf / opt/mysql-$ (date +% F) .tar.xz / usr/local/mysql/data/ # compressed backup
[root@localhost opt] # ls
Mysql-2018-08-30.tar.xz rh
Set scheduled tasks to execute automatically
[root@localhost opt] # crontab-e no crontab for root-using an empty one crontab: installing new crontab [root@localhost opt] # crontab-l 301 * tar jcvf / opt/mysql-$ (date +% F) / usr/local/mysql/data/ # set scheduled task automatic execution
Data recovery, decompress the backup file.
[root@localhost opt] # tar jxvf mysql-2018-08-30.tar.xz-C / usr/local/mysql/data/
The second backup method
Use the mysqldump tool to compress
Backup database
[root@localhost data] # mysql-uroot-p-e 'show databases 'Enter password: +-+ | Database | +-+ | information_schema | | mysql | | performance_schema | | school | | sys | | usr | [root@localhost ~] # mysqldump-uroot-p-databases school > / opt/school.sqlEnter password:
[root@localhost ~] # ls / opt
Mysql-2018-08-30.tar.xz rh school.sql
Delete database school
[root@localhost data] # mysql-uroot-p-e 'drop database school;show databases;'Enter password: +-+ | Database | +-+ | information_schema | | mysql | | performance_schema | | sys | | usr | +-+
Database restore
The first option:
[root@localhost] # mysql-uroot-p
< /opt/school.sqlEnter password: [root@localhost ~]# mysql -uroot -pabc123 -e 'show databases;'mysql: [Warning] Using a password on the command line interface can be insecure.+--------------------+| Database |+--------------------+| information_schema || mysql || performance_schema || school || sys || usr |+--------------------+ 第二种方案: [root@localhost ~]# mysql -uroot -pabc123mysql>Source / opt/school.sql
Attached:
Mysqldump makes a full backup of a single library
Mysqldump-u root-p-- databases school > / opt/school.sql
Full backup of multiple data
Mysqldump-u root-p-- databases mysql school > / opt/school-mysql.sql
Back up all libraries
Mysqldump-u root-p-- all-databases > / opt/all.sql
Back up the table
Mysqldump-u root-p school info > / opt/info.sql
Back up the table structure
Mysqldump-u root-p-d school info > / opt/info.sql
For the above about the Mysql database to create a full backup method, we do not think it is very helpful. If you need to know more, please continue to follow our industry information. I'm sure you'll like it.
