Für die Installation der MySQL-Datenbank stehen uns viele Optionen zur Verfügung. Die am häufigsten verwendeten sind die Binärinstallation und die Quellcodeinstallation. Die binäre Installationsmethode umfasst die RPM-Version und die Glibc-Version. Die RPM-Version wird unter einer bestimmten Linux-Version kompiliert. Wenn Ihre Linux-Version übereinstimmt, können Sie sie beispielsweise installieren. Wenn Sie ein RPM-Paket für RedHat6 oder RedHat7 kompiliert haben, laden Sie einfach die entsprechende Installation herunter. Es gibt ein weiteres binäres Installationspaket, das auf einer bestimmten Glibc-Version kompiliert wurde. In diesem Artikel wird hauptsächlich die Installation von MySQL auf Basis von Glibc beschrieben.
