• Software Installation
  1. RRDtool – I recommend that you install rrdtool from source, even if it is available as an optional binary package for operating system distribution. This is because NMIS expects that you’ve built and installed RRDTOOL something like this, and NMIS expects to find the rrdtool libraries under /usr/local/rrdtool/. This also installs RRDs,  the shared-library perl module supplied with rrdtool.
     1. wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.0.x/rrdtool-1.0.45.tar.gz
     2. $ gzip -dc rrdtool-1.0.45 | tar -xof –
     3. $ cd rrdtool-1.0.45
     4. $ ./configure –enable-shared –prefix=/usr/local/rrdtool
     5. $ make install site-perl-install
        1. The ‘site-perl-install’ tag is not so important for NMIS, but I use as it makes the rrdtool perl modules available to all perl scripts.  (See above.)
  2. SNMP Session – This package contains Perl 5 modules SNMP_Session.pm, BER.pm and SNMP_util.pm, which, when used together, provide access to remote SNMP (v1/v2) agents.  SNMP Session can be downloaded from the FTP directory ftp://ftp.switch.ch/software/sources/network/snmp/perl/.
     1. gzip -dc SNMP_Session-0.95 | tar -xof –
     2. cd SNMP_Session-0.95
     3. perl Makefile.PL
     4. make
     5. make test
     6. make install
  3. PERL modules – These are all installed the same way. I prefer the CPAN build process, as then any dependencies are picked up and installed for you.
     1. You can install them using the CPAN shell like this:
        1. LANG=en_US
        2. export LANG
        3. perl -MCPAN -e “shell”
        4. At the $cpan> enter in the following commands
           1. install Time::HiRes
           2. install Time::ParseDate
           3. install Statistics::Lite
           4. install Net::SNPP
           5. install Net::SMTP
           6. install Net::DNS
           7. install GD::Graph
• NMIS Install

1. Create nmis users and groups
   1. groupadd nmis
   2. useradd -g nmis -p ‘password’ nmis
   3. usermod -G nmis apache    # add apache user to group nmis, so the web interface can read/write conf files
2. Create folder and set permissions
   1. mkdir /usr/local/nmis
   2. chown nmis:nmis /usr/local/nmis
   3. chmod g+ws /usr/local/nmis
3. Uncompress and unpack the distribution
   1. gzip -dc nmis-3-2-0.tar.gz | tar -xof –
   2. Copy the files to the directory base
   3. cp -R nmis-3-2-0/* /usr/local/nmis/
4. Change all file ownership and permissions to nmis
   1. chown -R nmis:nmis /usr/local/nmis/
   2. chmod -R 0775 /usr/local/nmis/
5. Change nmis.pl  to the version of RRDtool you have install (for my example I’m using 1.0.45)
   1. vi +51 /usr/local/nmis/bin/nmis.pl
   2. use RRDs 1.000.450;
6. Setting up web access – Apache should already be working, easiest thing to do is add aliases for the relevant directories, as should have produced by the above command, ie:
   1. Alias /nmis/ “<BASE>/htdocs/”
   2. ScriptAlias /cgi-nmis/ “<BASE>/cgi-bin/”
   3. vi /etc/httpd/conf/httpd.conf
   4. service httpd restart
7. Automate the whole lot with CRON
   1. crontab -e (as root)
   2. Paste the following into the vi window:

# mail any errors to root
MAILTO=root@mydomain.com
