1. give and remove user rights

1.1 Give privileges:

mysql> grant all on wordpress.* to wordpress@localhost identified by 'password';

1.2 Remove privileges:

mysql> flush privileges;

2. create a table

mysql> create table table_name (name char(20));

3. insert a few records into the table you created

mysql> insert into table_name values('milton');

4. select some of the records in the table you created

mysql> select name from table_name;

5. change some of the records into the table you created

mysql> update table_name set name='johndoe' where name='milton';

6. delete records from the table you created

mysql> delete from table_name where name='johndoe';

7. How will you read records from in a plain text file into MySQL. Give an example.

Copy records to a plain text file:

mysql> select * into outfile '/tmp/database.txt' fields terminated by '\t' lines terminated by '\n' from table_name;

Import records from a plain text file:

mysql> load data infile '/tmp/database.txt' into table table_name fields terminated by '\t' lines terminated by '\n';

8. What are the exact sequence of steps that you need to take so that Apache logs can be read in from MySQL. Assume you have a default installation of Apache and a default installation of MySQL.

8.1 Create a database

8.2 Create a table with the fields I will need

8.3 Split the apache log file to a temporary file then mysql can recognize this file

8.4 Import this plain text file into the database

9. Name two security measures that MySQL recommmends

• Encrypt the passwords
• Add an password for the default system users like root and mysql.

10. Which MySQL log file, in your opinion, is important for you to keep track of and why?
