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

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

8.5 Create a shell script to keep updating the text file

9. Name two security measures that MySQL recommmends

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