how to install htop on centos
There are times you want to have a better control over the system processes and usage and also having a better visual of RAM and CPU usage on your server.As You may already know there is a Linux command called top which will show the resources and users cpu usage but it is not good enough to find out every thing in a glance, That for example you should go to the top right to see cpu usage let say it is 50%, then you have to think of your self in your mind that how much it has used the cpu.But by using htop you can see CPU usage of each core colorful and easily.This third party application will work perfectly on Cpanel Centos Servers.

Hi Farzin
Thanks for your comment
this post is for about 4 months ago and in they may have released this new version
and the guideline for installing the latest htop that you provided is related to building htop from the source by using make and make install that for some people it is so easy for achieving so by using the rpm package
I will provide the latest version for both 32bit and 64bit OS with the both rp and building from the source soon
Thanks

Excellent notes, thanks for posting.

Just a quick note: htop delay is in tenths of a second. Therefore, if you run:
htop -d 2
It will update 5 times per second, not every two seconds as suggested.

Hi dear wooshka
i found that the latest rpm version for htop is 0.7.1 , but htop 0.8.3 is available for download in sourceforge.
so here is its installation for your dear visitors .
i have downloaded the default sourceforge package in my cents os 5.4 64 bit and its working fine .
after downloading the file from source forge with wget
extract it with :
tar xzvf htop-0.8.3.tar.gz
then
cd htop-0.8.3
then
./configure
if no error is returned then
make
and after it is completed use
make install
now u can access htop with
# htop
thanks in advanced
