Solved: Locate command not working in Linux SSH, "No such file or directory"

If you run into this error when using the locate command:

Code:

root@server6:~# locate index.html

locate: can not stat () `/var/lib/mlocate/mlocate.db': No such file or directory

Here's the easy fix:

Code:

root@server6:~# updatedb

Just run updatedb and it will repair the problem.

What is updatedb? Updatedb updates file name databases used by GNU locate.
What is locate? Locate searches through a prebuilt database of files, and is significantly faster than find. However, it requires the database to be updated regularly.

My specific problem did not start until I stopped using root SSH logins, opting to instead "su -" to the root user after logging in from an alternate account. (This is done for safety, of course. Disallowing root SSH access prevents brute force hacking attempts on common defaults usernames -- i.e., "root".) This happened on an Ubuntu 10.10 server running ISPConfig 3.

Easy fix, simple issue. :thumb:

Servers always have problems. Having a good hosts helps prevent/avoid them!

Here's another example, from a CentOS 5 x86_64 server running Plesk 9 in a Virtuozzo VPS container.

I was trying to locate any file/folder with the name "bind", by typing in locate bind

Code:

[root@server ~]# locate bind

locate: can not open `/var/lib/mlocate/mlocate.db': No such file or directory

The fix from the first post also does not work: updatedb will hang.
In this scenario, a required package is not installed.

Type rpm -q mlocate vixie-cron anacron to see what's installed vs what's missing.

Code:

[root@server mlocate]# rpm -q mlocate vixie-cron anacron

mlocate-0.15-1.el5.2

vixie-cron-4.1-77.el5_4.1

package anacron is not installed

Anacron needs to be installed. That's best done with yum.
Note that by default Plesk disables yum, so the host will have to enable it manually.

Anacron RPM can be located here: http://rpm.pbone.net/index.php3/stat...86_64.rpm.html
