-After installing CentOS first thing to do is to update everything. So yum -y upgrade

-Download the Sphinx Tarball and untar it (wget http://sphinxsearch.com/files/sphinx-2.0.1-beta.tar.gz)

-Download the libstemmer library (the download link is in the INSTALL file, wget http://snowball.tartarus.org/dist/libstemmer_c.tgz)

-Make sure yum -y install gcc-c++ kernel-devel

-Also yum -y install mysql-devel

-Then do ./configure –with-libstemmer

-make -j4 install

And that’s it…the installation of Sphinx Search is complete!

Now you need to configure the sphinx.conf file. There is an excellent wiki available at http://sphinxsearch.com/wiki/doku.php

All you need to do is run export HISTTIMEFORMAT="%F %T " at the command line and you are done! Now run history and you’ll get your history with timestamps!

First command is :-
ip http server

This enables the http server

Second command is :-
username admin privilege 15 password password

This creates the user admin with password “password” and full priviliges.

Third command is :-
ip http authentication local

This enables the authentication to take place through the above created username and password

That’s it! After this you should be able to log in through the web portal

By default it searches for file contents. One simple way to JUST look for filenames is to prefix “name:” without quotes to your file name search. So instead of searching for readme.txt, search for name:readme.txt

Hope this helps somebody!
