centOS locate ： command not found 问题解决

跟随鸟哥的Linux私房菜进行学习的过程中，用locate 查找文件

提示
-bash: locate: command not found

那就先updatedb一下吧
提示
-bash: updatedb: command not found

baidu说updatedb 不能用先要安装 slocate

yum install slocate

提示
找不到 slocate 相应的包

原来是mlocate已经替换slocate了-------

[root@localhost tmp]#
yum -y install mlocate
Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

Complete!

但是
[root@localhost tmp]# locate passwd
locate: can not stat () `/var/lib/mlocate/mlocate.db': 没有那个文件或目录
安装成功了，现在使用 updatedb 命令来创建locate命令依赖的数据库。
[root@localhost tmp]# updatedb

这样就OK了
