求 Linux mysql初始化数据库报错

could not find my_print_defaults
the following directories were searched：
/usr/local/mysql/bin
/usr/local/mysql/extra
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 pointingto that location

怎么安装的数据库，如果是源码，你需要make install后，把路径添加到系统路径中。
如果想简单就要包管理器安装，yum等，这样就会自动安装到系统路径。
