装好系统发现使用locate查找文件，提示
-bash: locate: command not found
yum install locate 无效，看来locate不是软件名称
[root@centos64 ~]# yum search locate
============================= N/S Matched: locate
==============================
mlocate.x86_64 : An utility for finding
files by name
which.x86_64 : Displays where a particular program in
your path is located
[root@centos64 ~]# yum install mlocate
[root@centos64 ~]# locate mysql
locate: can not stat ()
`/var/lib/mlocate/mlocate.db‘: 没有那个文件或目录
[root@centos64 ~]# updatedb
完成。
linux locate: command not found
