+# If you install MySQL on some other places than /home/hkc/workspace/app/mysql-5.7.32/build/__install, then you
+# have to do one of the following things for this script to work:
+#
+# - Run this script from within the MySQL installation directory
+# - Create a /etc/my.cnf file with the following information:
+#   [mysqld]
+#   basedir=<path-to-mysql-installation-directory>
+# - Add the above to any other configuration file (for example ~/.my.ini)
+#   and copy my_print_defaults to /usr/bin
+# - Add the path to the mysql-installation-directory to the basedir variable
+#   below.
+#
+# If you want to affect other MySQL variables, you should make your changes
+# in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.
+
+# If you change base dir, you must also change datadir. These may get
+# overwritten by settings in the MySQL configuration files.
