The Soothingly Seamless Setup of Apache, SSL, MySQL, and PHP - Game Plan (
Page 5 of 11 )
Our plan is first to
install the MySQL server and ensure that it works. Then we'll install PHP and
Mod_SSL. We will then install the Apache web server. Finally, after we have
installed Apache we will test to see if PHP and Mod_SSL are functioning
correctly.
You should note that:
- /usr/local/apache
- /usr/local/mysql
- /usr/local/ssl
are the locations we installed Apache, MySQL,
and Mod_SSL/OpenSSL. You can install to different directories by changing the
"prefix" option before installation.
Text that is indented and between
horizontal rules is the expected input and output to and from your computer. The
black text is what you enter. The
red text means that you may have to change it to fit your
circumstances. The
green text is what the
computer should display by itself.{mospagebreak title=MySQL Source Installation
(*NIX)} The basic commands to unpack and install the MySQL source distribution
from a `tar' file:
Become ROOT by using su.
# su
Change directly to where you have the tar file. (use a temp
directory. I used /tmp/download/)
# cd /tmp/download/
Extract the files using the following command.
# gunzip -dc mysql-3.22.32.tar.gz | tar xvf -
Change to the NEW directory which was created during the
extract.
# cd mysql-3.22.32
Now you can run "configure" for the MySQL server. You can
specify many options with the configure command. Type "configure --help" to see
all options. We're using the "--prefix" option to specify the direct path to the
installation location. Configure will check for your compiler and a couple of
other things. If you have any errors you can check the config.cache file to see
the errors.
# configure --prefix=/usr/local/mysql
After you are done with the configure. You can make the
actual binaries by executing the following line (this will take a while).
# make
Now you are ready to install all the binaries. Run the
following lines to install the binaries to the directory you specified with the
configure "--prefix" option.
# make install
Now it is time to create the mysql tables used to define the
permissions. Make sure you replace "new-password" with something of your choice,
otherwise, new-password will be your root password.
# scripts/mysql_install_db
# cd /usr/local/mysql/bin
# ./safe_mysqld &
# ./mysqladmin -u root password 'new-password'
You can ensure that MySQL is working by running some simple
tests to verify that the server is working. The output should be similar to what
is shown below:
# BINDIR/mysqlshow
-p
Enter password:

Once you install MySQL, it will automatically create two databases.
One is the mysql table which controls users, hosts, and database permissions in
the actual server. The other is a test database. We could use the test database,
however, we want to give you a quick and simple overview of some of the command
line options available with MySQL. Also, this will ensure that root has been set
up with full access to the database server (i.e. root has permission to create
databases, tables, etc.) We will create a "test2" database that we will use
later for our testing after logging into the MySQL server.
#mysql -u root
-pEnter
password:mysql> show databases;

test |
| |
| + |
-------------------- |
+ |
2 rows in set (0.00 sec) mysql> create
database test2; Query OK, 1 row affected (0.00 sec)
Now select the test2 database, and create a new table called
tst_tbl, with the two following fields. Field 1, which is an id field which lets
you know the id of the record. Essentially, this is just a row number for
simplicity. The second field is a name field in which you will store name
information about books. The formats for these fields are.. field 1 (id) is an
integer (int) of length 3, and field 2 (name) is a character (char) field of
length 50. We assign id to be the key for searching and indexing the data.
y NOTE: MySQL commands are not case-sensitive. For example, CREATE and
cReatE will be interpreted the same way. Also, remember to add a semi-colen
after your commands.
mysql> use
test2;
Database changed
mysql> CREATE TABLE books (
-> id int(3) not null auto_increment,
-> name char(50) not null,
-> unique(id),
->
primary key(id)
-> );
Query OK, 0 rows affected (0.00 sec)
Now we can verify that indeed everything is correct with the
following commands.
mysql> show
tables;

Notice that the describe command basically "describes" the table
layout. Pretty cool hey?!
Ok, time for some really useful SQL commands,
inserting and selecting data from the database. It's time to add several records
to the new table. Remember these are simple records of book names, but once you
have gained enough experience with SQL you can create really complex databases
for some great e-commerce sites. Let's create two records of two fictitious
books. The first record is the name of a book I plan on writing some day, "PHP 4
Newbies." The other is a useful book for Linux, "Red Hat Linux 6 Server", by
Mohammed J. Kabir.
mysql> INSERT INTO books (name) values('PHP 4
Newbies');Query OK,
1 row affected (0.00 sec)mysql> INSERT INTO books
(name) values('Red Hat Linux 6 Server');Query OK, 1 row affected (0.00 sec)
Now we can check the new records, and issue a select all command.
mysql> SELECT *
from books;

Great, the MySQL server is fully functional. We could continue to
add records, but it makes no sense at this time. Notice how you did not have to
specify the id number when you inserted the record in the database. This is
because you created the id field with the auto_increment option enabled.
Let's learn how do a quick delete. This is just for your info, remember
that you can find everything you may need about the MySQL commands and the
server at the mysql web site at http://www.mysql.com.
mysql> delete from books where id=1; Query OK, 1 row affected (0.00
sec) mysql> select * from books;

Ok, exit MySQL and continue with the setup...you can play with
MySQL later after you have completed all the installations and everything is
working properly.
