This article provides you with information on how to manage MySQL on CentOS 7 server using root.<\/span><\/p><\/blockquote>\n

\u00a0<\/span><\/p>\n

\u00a0<\/span><\/p>\n

\u00a0<\/span><\/p>\n

First, we\u2019ll log in to the MySQL server from the command line with the following command:<\/span><\/p>\n

\u00a0<\/span><\/p>\n

mysql -u root -p<\/code><\/span><\/p>\n

\u00a0<\/span><\/p>\n

In this case, I\u2019ve specified the user root<\/strong> with the -u<\/strong> flag and then used the -p<\/strong> flag so MySQL prompts for a password. Enter your current password to complete the login.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

You should now be at a MySQL prompt that looks very similar to this:<\/span><\/p>\n

mysql><\/code><\/span><\/p>\n

\u00a0<\/span><\/p>\n

View All MySQL Databases<\/span><\/strong><\/span><\/span><\/h2>\n

To view a list of databases simply issue the following command:<\/span><\/p>\n

SHOW DATABASES;<\/code><\/span><\/p>\n

\u00a0<\/span><\/p>\n

Your result should be similar to this:<\/span><\/p>\n

\u00a0
mysql> SHOW DATABASES;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| test |
+--------------------+
4 rows in set (0.00 sec)
<\/code><\/span><\/p>\n

Update a Database user password in MySQL<\/span><\/strong><\/span><\/span><\/h2>\n

We\u2019ll update the password for all MySQL users with the name root<\/strong>. Be sure to replace your_new_password<\/strong> with the actual new password:<\/span><\/p>\n

\u00a0<\/span><\/p>\n

update user set password=PASSWORD('your_new_password') where User='root';<\/code><\/span><\/p>\n

Note: You can change the password for any user with the above command. Simply specify that user\u2019s username in place of root.<\/strong><\/span><\/div>\n

\u00a0<\/span><\/p>\n

Finally, reload the privileges:<\/span><\/p>\n

flush privileges;<\/code><\/span><\/p>\n

Delete a Database in MySQL<\/span><\/strong><\/span><\/span><\/h2>\n

It only takes one simple command to delete a database in MySQL, but BEWARE; dropping a database can not be undone! The command is as follows:<\/span><\/p>\n

\u00a0<\/span><\/p>\n

DROP DATABASE tutorial_database;<\/code><\/span><\/p>\n

\u00a0<\/span><\/p>\n

If a database with the name tutorial_database<\/strong> does not exist, then you\u2019ll receive this error:<\/span><\/p>\n

\u00a0<\/span><\/p>\n

ERROR 1008 (HY000): Can't drop database 'tutorial_database'; database doesn't exist
<\/code><\/span><\/p>\n

\u00a0<\/span><\/p>\n

To avoid seeing this error use the following command instead:<\/span><\/p>\n

\u00a0<\/span><\/p>\n

DROP DATABASE IF EXISTS tutorial_database;<\/code><\/span><\/p>\n

\u00a0<\/span><\/p>\n

The above command will only drop the database tutorial_database<\/strong> if a database of that name exists.<\/span><\/p>\n

<\/h2>\n
