MySQL 8.0 Reference Manual
MySQL 8.0 Release Notes
By default, when you install MySQL after compiling it from source,
the installation step installs files under
/usr/local/mysql. The component locations
under the installation directory are the same as for binary
distributions. See Table 3.1, “MySQL Installation Layout for Generic Unix/Linux Binary Package”,
and Section 5.1, “MySQL Installation Layout on Microsoft Windows”. To configure
installation locations different from the defaults, use the
options described at
Section 4.7, “MySQL Source-Configuration Options”.
