Which Unneeded Services to disable in Centos?
| Posted by rasputinj, 11-15-2004, 01:42 AM |
| 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?

| 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 certain 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.

| okey ! so how can i remove them !?
|
| Posted by apollo, 11-15-2004, 10:19 AM |
| 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

| 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.
