I am running Centos and want to disable any unneeded services is looks like I do not need mdmonitor, and mdmpd, cups, rhnsd. Or do I need any of these?

What are you using the server for?

cups=printing service
mdmpd=monitor raid devices
mdmonitor=monitor raid devices
rhnsd=used to query redhat for updates

I am using it for a webserver. I was just wondering what other services are not needed.

You can usually safely disable the following if they are enabled:

Anacron
Cups
Finger
GPM
ISDN
Kudzu
Portmap
rhnsd - On a CentOS system, you are likely to be using YUM
Telnet


There could be more. This is just a sample list of what may be enabled and what you can switch off. Another way is to simply google each service one by one and decide if you need that particular service. Just do it once and you would be set for future.

well..I guess there are some more to remove/switch off:

ypbind,nfs,snmpd,saslauthd,netfs,gpm,pcmcia,sendmail....

Those usually are off by default,. Sendmail not necessarily so if it is just a stock machine and you need to send emails and is using sendmail. PCMCIA definitely.

yeah, but removing not needed rpm's are also a good idea ;)

okey if i remove them , will i see any change ? cpu load ? or more free memory ?

-more hdd space ;)
-quicker OS updates
-less bandwidth consumption (update downloads, if any)

;)

okey ! so how can i remove them !? :)

try
"man rpm"

but usually

rpm -e "program name goes here"

you can see what rpm's you have installed by "rpm -aq"

you can also filter it thru grep. e.g.

rpm -aq|grep programname

thanks apollo !

Zend is not a bad idea to have installed. I do not think it can really hinder the performance of your server and it will help some things run better. Some scripts also require zend optimizer, especially billing scripts.

Should you stop the service first? Then remove the rpm or does it matter.

I also found this article it is a bit dated but gives some good info.

Normally when you remove an rpm it will kill the process.

you can disable FreeWnn & Canna if you are not japanese :D

they are Japanese input systems
