Simple automated installation

Overview Copied

This page describes the procedure to undertake an automated fresh installation of the Opsview Monitor software, which is our recommended method.

Note

If you are looking at upgrading or migrating your current installation, please refer to Migrating Opsview Monitor 6.x to see which page is better suited for your scenario.

A number of considerations:

Note

We recommend you update your system to the latest OS packages before installing Opsview Monitor.

Supported operating systems Copied

Please refer to the list of supported operating systems.

Authorisation Copied

Please ensure that any proxies are unset and Opsview addresses are whitelisted. For more information, see Planning your System.

Installation Copied

To install, run:

curl -sLo- https://deploy.opsview.com/6 | sudo bash -s -- -p PASSWORD -s SOFTWARE_KEY -y

To learn about all the options available, you can check the help flag:

curl -sLo- https://deploy.opsview.com/6 | sudo bash -s -- -h

Optional SHA256 checksum verification Copied

You can also verify the script before running it by comparing the checksum you get with:

curl -L https://deploy.opsview.com/6 > opsview_deploy
sha256sum opsview_deploy

Ensure the returned string matches the following:

de9f4a1098d34993b84f7f2f4fa80b1461c14b5fd80a63de5f4a110fd07fce1d

You can then run the installation (and optionally provide the arguments):

sudo bash ./opsview_deploy -p PASSWORD -s SOFTWARE_KEY -y

NGINX change (SSL Certificates) Copied

Nginx is designed to use only one file that is a combination of your SSL Certificate (server.crt, if you have not renamed it) and your IntermediateCA file. Therefore you need to combine the your SSL certificate file and the IntermediateCA.crt into one single concatenated file in order for Nginx to start successfully.

If you find that your homepage/web-page is not loading up correctly please consider this change may need to be made for Nginx to start (the Opsview component that starts Nginx is opsview-webserver):

cd /opt/opsview/webapp/etc/ssl/
cp -p server.crt server.crt.backup

Replace the below file names appropriately:

cat SSL_Certificate_filename IntermediateCA.crt_filename > server.crt

Now that this is complete, opsview-webserver should start without issue.

Logging in Copied

During the installation, a single administrative user will have been created. The credentials for this user are:

username: admin
password: <password supplied during installation>

After the system is activated, carry out a reload by navigating to Configuration > Apply Changes and click Apply Changes.

Problems with installations Copied

If you encounter any problems with the installation, it is safe to rerun the command again.

You are also able to continue the installation from a checkpoint for the following reasons:

The automated installation consists of four steps that can be partially executed:

Step name Description Output from Automated Installation script
repo Add Opsview package repository. [*] Adding the Opsview package repository
boot Install and configure our deploy tool. [*] Installing Opsview Deploy
fire Configure the firewall rules for the Web UI. For a full list of ports and extra manual firewall rules, see Ports. [*] Adding HTTP/HTTPS rules to the local firewall
inst Use the deploy tool to install Opsview. [*] Running Opsview Deploy

With that in mind, we can then use the -A and -O flags to install up to a certain step or install only that step respectively. While the examples before would run all the four steps in order, this one would rerun all four steps:

curl -sLo- https://deploy.opsview.com/6 | sudo bash -s -- -A inst

This second example would just run the firewall step:

curl -sLo- https://deploy.opsview.com/6 | sudo bash -s -- -O fire

If you entered your software key incorrectly (which will fail at the inst step), the command below will remove the incorrect key, re-create the configuration file and re-run the installation:

sudo rm /opt/opsview/deploy/etc/user_vars.yml
curl -sLo- https://deploy.opsview.com/6 | sudo bash -s -- -p PASSWORD -s SOFTWARE_KEY -y -O boot,inst
