Usually you can find a program under a subdirectory "../bin". System programs are under /usr/bin or /bin. To check where files of mysql package are placed, on RHEL 6 type like this :
通常你可以在子目录“../bin”下找到一个程序。系统程序在/usr/bin 或/bin 下。要检查 mysql 包文件的放置位置，在 RHEL 6 上键入如下：
rpm -ql mysql(which is the main part of the package)
rpm -ql mysql （这是包的主要部分）
and the result is a list of "exe" files such as "mysqladmin" tool. About to know the version of the server, run the command:
结果是“exe”文件列表，例如“mysqladmin”工具。即将知道服务器的版本，运行命令：
mysqladmin -u "valid-user" version
