Installation Procedure

...

Preparing the pre-requisites

On Debian and derivatives, run this as root: 

apt-get install apache2 rrdtool apache2-utils unixodbc odbcinst tdsodbc

On CentOS/RHEL, run the following commands as root:

...

yum install http://mirror.optus.net/epel/6/i386/epel-release-6-8.noarch.rpm
yum install httpd-tools freetds unixODBC rrdtool httpd
echo -e "[FreeTDS]\nDriver = /usr/lib64/libtdsodbc.so.0" | odbcinst -i -r -d 

Installing opCharts

• Download opCharts and the custom rrdtool from the Opmantek website.
  Copy the two tarballs to the server in question, using scp or sftp or similar. Make a record of where you put the tarball (likely root's home directory).

• Become root and unpack the tarballs:

  Code Block

• Create the required nmis user
  As root run

  Code Block
  useradd nmis

• opCharts is now unpacked into /usr/local/omk, and the default configuration files are in /usr/local/omk/conf, ready for your initial config adjustments.

Initial System Configuration and Integration steps

• Make sure the opCharts logs are rotated
  If your system runs  logrotate daily and automatically (i.e. Debian/Ubuntu), simply copy conf/omk-rotate.conf to /etc/logrotate.d/.

  Code Block
  theme Emacs
  # on Debian/Ubuntu, as root: cp /usr/local/omk/conf/omk-rotate.conf /etc/logrotate.d/

  On other systems you will have to create a suitable cron job:

  Code Block
  # as root: crontab -e# insert the following lines, then save and quit # Check to rotate the logs 02:05 every day 2 5 * * * /usr/sbin/logrotate /usr/local/omk/conf/omk-rotate.conf

• Integrate opCharts with the web server
  become root and run the following commands:

  Code Block
  # as root # non-debian: cp /usr/local/omk/conf/04omk-proxy.conf /etc/httpd/conf.d/ apachectl restart # debian/ubuntu: cp /usr/local/omk/conf/04omk-proxy.conf /etc/apache2/conf.d/ /etc/init.d/apache2 restart

  Note: If this step is not taken, then the opCharts web GUI will only be available on port 8042 and you'll need to adjust your web browser accordingly.

• Make the opCharts service daemon start automatically with the system
  become root, then run the  following commands:

  Code Block
  # as root cd /usr/local/omk/install cp omkd.init.d /etc/init.d/omkd # non-debian: chkconfig omkd on # debian/ubuntu: update-rc.d omkd defaults

• Start the opCharts service daemon
  become root, then run the following commands:

  Code Block
  service omkd start

• Test opCharts
  open up a web browser, and point it to "http://<yourserverip>/omk/opCharts"; you will have to enter your license first, then you will see opCharts main dashboard.
