CentOSでMySQL4をインストールしたい場合は、次のようにします。ここでは4.1.22を使っています。

——————————–
mv /etc/my.cnf /etc/my.cnf.original
cd /usr/local/src
tar xzf mysql-4.1.22.tar.gz
cd mysql-4.1.22
./configure –prefix=/usr/local/mysql-4.1 \
–with-charset=utf8 –with-extra-charsets=all \
–with-mysqld-user=mysql –with-readline \
–with-tcp-port=3306 \
–with-unix-socket-path=/usr/local/mysql-4.1/var/mysql.sock
make
make install
mkdir /usr/local/mysql-4.1/var
cp /usr/local/mysql-4.1/share/mysql/my-medium.cnf /usr/local/mysql-4.1/var/my.cnf
scripts/mysql_install_db
chown -R mysql.mysql /usr/local/mysql-4.1/var
cp /usr/local/mysql-4.1/share/mysql/mysql.server /etc/rc.d/init.d/mysqld4
service mysqld4 start
