MRTG INSTALL RPM or TAR

If you do not have zlib installed:
wget http://www.gzip.org/zlib/zlib-1.1.4.tar.gz
gunzip -c zlib-*.tar.gz tar xf -
rm zlib-*.tar.gz
mv zlib-* zlib
cd zlib
./configure
make
cd ..


======
If you don't have libpng installed
wget http://public.planetmirror.com/pub/sourceforge/l/li/libpng/libpng-1.0.15.tar.gz
gunzip -c libpng-*.tar.gz tar xf -
rm libpng-*.tar.gz
mv libpng-* libpng
cd libpng
make -f scripts/makefile.std CC=gcc ZLIBLIB=../zlib ZLIBINC=../zlib
rm *.so.* *.so
cd ..


=============
For versions up to 1.8.4, try:

make
cp .libs/* .


============= MRTG
cd /usr/local/src
gunzip -c mrtg-2.12.1.tar.gz tar xvf -
cd mrtg-2.12.1If all the libraries have been preinstalled on your system you can configure mrtg by doing a simple:
./configure --prefix=/usr/local/mrtg-2Otherwise you may have to give some hints on where to find the various libraries required to compile mrtg:
./configure --prefix=/usr/local/src/mrtg-2 --with-gd=/usr/local/src/mrtg/gd --with-zlib=/usr/local/src/mrtg/zlib --with-png=/usr/local/src/mrtg/libpng
make
make install


================Confiure
cfgmaker --global 'WorkDir: /home/httpd/mrtg' \
--global 'Options[_]: bits,growright' \
--output /home/mrtg/cfg/mrtg.cfg \
community@router.abc.xyz


=============== RunAsDaemon:
Yesto your mrtg configuration file and then creating a startup script in your system startup sequence. Unfortunately, adding startup scripts differs widely amongst different unix systems. The modern ones normally have a directory called /etc/init.d or /etc/rc.d/init.d where you put scripts which starts the process you want to run when the system boots. Further you must create a symbolic link in /etc/rc3.d or /etc/rc.d/rc?.d called S65mrtg (this is just a sample name ... it is just important that it starts with S followed by a two digit number). If you are not sure about this, make sure you consult the documentation of your system to make sure you get this right.

Install Yum in RHEL3

Now I have a fully updated system. Following is the brief summary of the steps I took

1) Since I was behind a proxy I had to export environment variable http_proxy.

2) Downloaded yum-2.0.8-1.noarch.rpm fromhttp://linux.duke.edu/projects/yum/download/2.0/yum-2.0.8-1.noarch.rpm

3) Installed it usingrpm –i yum-2.0.8-1.noarch.rpm

4) Configured my yum.conf to look like this:

[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1

#base]
#name=Red Hat Linux $releasever - $basearch - Base
#aseurl=http://mirror.dulug.duke.edu/pub/yum-
repository/redhat/$releasever/$basearch/

[base]
name=CentOS-$releasever - Base
baseurl=http://mirror.centos.org/centos/3/os/i386/
gpgcheck=1

[updates]
name=Red Hat Linux $releasever - Updates
baseurl=http://mirror.centos.org/centos/3/updates/i386/
gpgcheck=1

5) Downloaded the gpg key for CentOS rpm packages fromhttp://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-3

6) Imported the key like this:rpm --import RPM-GPG-KEY-CentOS-3

7) Run “yum –y update”. Now Sit back and enjoy seeing your system being updated.

Enjoy!
