FATAL ERROR: Could not find mysqld

The following directories were searched:

    /usr/share/libexec
    /usr/share/sbin
    /usr/share/bin

If you compiled from source, you need to run 'make install' to
copy the software into the correct location ready for operation.

If you are using a binary release, you must either be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.

chmod: cannot access `/var/lib/mysql/mysql': No such file or directory

Same cnf in #2. Removing basedir option worked.
