MySQL-4.0.15a

Introduction to MySQL

MySQL is a widely used and fast SQL database server. It is a client/server implementation that consists of a server daemon and many different client programs and libraries.

Installation of MySQL

For security reasons, running the server as an unprivileged user and group is strongly encouraged:

groupadd mysql &&
useradd -c mysql -d /dev/null -g mysql -s /bin/false mysql

Build and install MySQL by running the following commands:

cp configure configure.old &&
sed -e "s%mysql-test/Makefile%%" -e "s% mysql-test%%" configure.old > configure &&
./configure --prefix=/usr \
            --sysconfdir=/etc \
            --libexecdir=/usr/sbin \
            --localstatedir=/var/lib/mysql \
            --enable-thread-safe-client \
            --enable-local-infile \
            --without-debug \
            --without-bench &&
make &&
make install

Command explanations

sed -e "s%mysql-test/Makefile%%" -e "s% mysql-test%%" configure.old > configure: This sed is used to disable the mysql test suite.

Configuring MySQL

cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

mysql_install_db
chown -R mysql:mysql /var/lib/mysql

mysqld_safe --user=mysql 2>&1 >/dev/null &

mysql -uroot mysql

Certain MySQL support programs may require the Perl DBI modules to be installed to function properly.
