1.  MySQL 설치

작업의 대부분은 Ubuntu – 10.04 버전에서 진행하였다.

Ubuntu Linux의 경우 MySQL 은 기본적으로 설치가 되어있으나, 다른 Linux 배포판의 경우, 설치가 안되어 있거나 따로 설치를 해야할 경우가 있다.

이럴 경우, 대부분의 최신의 배포판들은 다음의 명령어를 사용하여 간단하게 설치를 진행할 수 있다.

apt-get 을 이용할 경우

# apt-get install mysql

yum 을 이용할 경우

# yum install mysql

이번 프로젝트에서 사용한 MySQL의 버전은 5.1.41 버전이다.

MySQL 버전 확인하기

# mysql –version

 

2. MySQL Options

ubuntu 환경에서 apt-get 으로 MySQL을 설치 했을 경우, 기본적으로 설정되는 database directory는 다음과 같다.

/var/lib/mysql

만약 위의 디렉토리에 존재하지 않는다면, /etc/mysql/my.cnf 파일을 통해서 database directory 의 위치를 확인할 수 있다.

아래는 필자의 my.cnf 파일의 내용이다.

#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# – “/etc/mysql/my.cnf” to set global options,
# – “~/.my.cnf” to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with –help to get a list of available options and with
# –print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain “#” chars…
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.
