==Show SQL commands that work on MySQL for:==
===give and remove user rights===
====give/grant user right====
mysql> grant all on wordpress.* to wordpress@localhost identified by 'dumpling';
====remove user right====
mysql> flush privileges;
=== create a table===
mysql> create table ''table_foo'' (rec1 char(9));
===insert a few records into the table you created===
mysql> insert into ''table_foo'' values('record1');
mysql> insert into ''table_foo'' values('record2');
mysql> insert into ''table_foo'' values('record3');
===select some of the records in the table you created===
mysql> select rec1 from ''table_foo'';
===change some of the records into the table you created===
mysql> update ''table_foo'' set name='record0' where rec1='record2';
===delete records from the table you created===
mysql> delete from ''table_foo'' where rec1='record3';
===How will you read records from in a plain text file into MySQL. Give an example.===
=====Exporting records=====
mysql> select * into outfile '/tmp/mysql_test/table_foo.txt' fields terminated by '\t' lines terminated by '\n' from ''table_fo'';
=====Importing records =====
mysql> load data infile '/tmp/mysql_test/table_foo.txt' into table ''table_foo2'' fields terminated by '\t' lines terminated by '\n';
===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.===
It's just like how we do it for wordpress. First, make sure apache and mysql are all installed and running properbly. Then, create a database and table, also create the fileds that we'll need, e.g: hour, minutes, status, etc. Then it's the tricky part, we have to extra the apache log file's lines into different filed, so that mysql can read it. You can acheive it with 'sed' or some other command or even script. We actually have a python script from Danny's assignment that has simular function. We could adjust the script to acheive the task. then, we can import the text file with mysql command 'load data infile'.
===Name two security measures that MySQL recommmends===
1.always have set a password
2.use a long password with combination of characters and numbers
===Which MySQL log file, in your opinion, is important for you to keep track of and why?===
In my opintion, i think The General Query Log is the most important. Assuming the database has already installed and running properly. The most critical things is data leaking.
It is really important, because you do not want any random people to the record. The database may contain some sensitive records, e.g: VISA numbers, address.

===As you observe from the tutorials, many users have added their own comments in addition to the MySQL material. Which two comments (one from the using tutorial and one from the administration tutorial) you think were useful to you.===
====Tut====
It fill in a lot of gap that the tutorial didn't cover.

====Admin====
A lot of experience sharing
