Create mysql database in ubuntu shell

On a default settings, mysql root user do not need a password to authenticate from localhost. In this case, ou can login as root on your mysql server using:

$ mysql -u root

If a password is required, use the extra switch -p:
$ mysql -u root -p
Enter password:

Now that you are logged in, we create a database:
mysql> create database amarokdb;
Query OK, 1 row affected (0.00 sec)

We allow user amarokuser to connect to the server from localhost using the password amarokpasswd:
mysql> grant usage on *.* to amarokuser@localhost identified by 'amarokpasswd';
Query OK, 0 rows affected (0.00 sec)

And finally we grant all privileges on the amarok database to this user:
mysql> grant all privileges on amarokdb.* to amarokuser@localhost ;
Query OK, 0 rows affected (0.00 sec)

And that's it. You can now check that you can connect to the MySQL server using this command:
$ mysql -u amarokuser -p'amarokpasswd' amarokdb
Your MySQL connection id is 12
Server version: 5.0.38-Ubuntu_0ubuntu1-log Ubuntu 7.04 distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.


securing MYSQL and setting a Password


Mysql Backup and Restore

Bakcup a single database

done from bash - no need to log in to mysql
mysqldump -u root -ppassword sugarcrm > sugarcrm.sq


mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql

Backup a single table

mysqldump -u root -ppassword databasename table > sugarcrm.sq

Backupup Multiple Database

log into mysql

mysql -u root -pyourpassword

mysql> show databases;

this will give you a list of databases

For example, if you want to take backup of both sugarcrm and bugs database, execute the mysqldump as shown below:

mysqldump -u root -ptmppassword --databases bugs sugarcrm > bugs_sugarcrm.sql

Verify the bugs_sugarcrm.sql dumpfile contains both the database backup.

# grep -i "Current database:" /tmp/bugs_sugarcrm.sql

-- Current Database: `mysql`

-- Current Database: `sugarcrm`

Backup all the databases:

The following example takes a backup of  all the database of the MySQL instance.

# mysqldump -u root -ptmppassword --all-databases > /tmp/all-database.sql

Backup a specific table:

In this example, we backup only the accounts_contacts table from sugarcrm database.

mysqldump -u root -ptmppassword sugarcrm accounts_contacts > /tmp/sugarcrm_accounts_contacts.sql 

Restore Database

mysql -u username -p database < dump_file.sql
