Installing Webmin on Debian

Installing Webmin on Debian

If you are using the DEB version of webmin, first download the file and then run the command :

dpkg –install webmin_1.480_all.deb

The install will be done automatically to /usr/share/webmin, the administration username set to root and the password to your current root password.

You should now be able to login to Webmin at the URL http://localhost:10000/. Or if accessing it remotely, replace localhost with your system’s IP address.

If Debian complains about missing dependencies, you can install them with the command :

apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl

If you are installing on Ubuntu and the apt-get command reports that some of the packages cannot be found, edit /etc/apt/sources.list and make sure the lines ending with universe are not commented out.

Some Debian-based distributions (Ubuntu in particular) don’t allow logins by the root user by default.

However, the user created at system installation time can use sudo to switch to root. Webmin will allow any user who has this sudo capability to login with full root privileges.

If you want to connect from a remote server and your system has a firewall installed, see this page for instructions on how to open up port 10000.

We need a codec directory

mkdir /usr/local/lib/codecs/

Install Ruby on Rails, subversion & ncurses

apt-get install subversion ruby libcurses-ruby

Run some SVN queries

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer
cd /usr/local/src/mplayer
svn update

Copy Codecs for mplayer

mv /usr/local/ffmpeg/essential-20061022/* /usr/local/lib/codecs/
chmod -R 755 /usr/local/lib/codecs/

We also need to secure the tmp directory

mkdir /usr/local/ffmpeg/tmp
chmod 777 /usr/local/ffmpeg/tmp
export TMPDIR=/usr/local/ffmpeg/tmp

Enable service at boot time on debian server

Enable service at boot time on debian server

To enable the a service on debian server at boot time you can use the following commands

update-rc.d service_name start NN runlevel . stop NN runlevel

where NN decide which order to run the scripts in the /etc/init.d folder.

Example

update-rc.d httpd start 20 2 3 4 5 . stop 20 0 1 6 .
update-rc.d httpd defaults

Both the command will start httpd service in run-levels 2, 3, 4, and 5, and stop the service in run-levels 0, 1, and 6.

To stop a service from starting on bootup, execute the command

update-rc.d –f service_name remove
Example: update-rc.d -f httpd remove

This command will stop the service httpd from starting when the server is booted.

To manually start a service you can use the command

/etc/init.d/httpd restart
invoke-rc.d httpd restart
