RPM Installation

This topic describes how to install Moogsoft Enterprise v8.2.0 on a single host.

Follow these steps if you have root access to the machine or machines on which you will install Moogsoft Enterprise, and you can connect to Yum repositories outside your network from those machines.

To install Moogsoft Enterprise in a highly available distributed environment, see High Availability Installation.

For Tarball installation steps, see Tarball Installation.

Before you begin

Before you start to install Moogsoft Enterprise, complete all steps in one of the following documents:

  • Online RPM pre-installation: If you have root access to the machine or machines on which you will install Moogsoft Enterprise, and you can connect to Yum repositories outside your network from those machines.

  • Moogsoft Enterprise - Offline RPM pre-installation: If you have root access to the machine or machines on which you will install or upgrade Moogsoft Enterprise, but you cannot connect to Yum repositories outside your network from those machines.

Install Moogsoft Enterprise

To complete an RPM installation of Moogsoft Enterprise v8.2.0, perform the following steps:

  1. Download and install the Moogsoft Enterprise RPM packages, using one of the following methods according to your deployment type:

    • If you are performing an RPM installation:

      VERSION=8.2.0; yum -y install moogsoft-server-${VERSION} \
moogsoft-db-${VERSION} \
moogsoft-utils-${VERSION} \
moogsoft-search-${VERSION} \
moogsoft-ui-${VERSION} \
moogsoft-common-${VERSION} \
moogsoft-mooms-${VERSION} \
moogsoft-integrations-${VERSION} \
moogsoft-integrations-ui-${VERSION}

    • If you are performing an offline RPM installation, navigate to the location where you copied the RPM files and install them:

      yum install *.rpm

  2. Edit your ~/.bashrc file to contain the following lines:

    export MOOGSOFT_HOME=/usr/share/moogsoft
export APPSERVER_HOME=/usr/share/apache-tomcat
export JAVA_HOME=/usr/java/latest
export PATH=$PATH:$MOOGSOFT_HOME/bin:$MOOGSOFT_HOME/bin/utils 

  3. Source the ~/.bashrc file:

    source ~/.bashrc

  4. Run the Percona install script:

    bash install_percona_nodes.sh;

    The script guides you through the installation process. To configure a single database node on the same server as Moogsoft Enterprise, use these settings:

    • Configure Percona as "Primary".

    • Do not set the server to "DB only".

    • Set the first database node IP address to the server IP address.

    • When prompted to enter the IP addresses of the second and third nodes, press Enter to skip these settings.

Initialize Moogsoft Enterprise

When the installation process is complete, initialize Moogsoft Enterprise as follows:

  1. Run the initialization script moog_init, replacing <zone name> with your desired RabbitMQ VHOST:

    $MOOGSOFT_HOME/bin/utils/moog_init.sh -I <zone_name> -u root

    The script prompts you to accept the End User License Agreement (EULA) and guides you through the initialization process.

    When asked if you want to change the configuration hostname, say yes and enter the public URL for the server. The public URL is the URL the instance will be connected to through a browser.

  2. If you are deploying more than one database, configure HA Proxy to load-balance the database nodes. The following script requires root privileges. Run this script on any host running any Moogsoft Enterprise components. Provide your "speedy" Yum repo user credentials when prompted:

    cat > aiops_repo.sh << _EOF_
#!/bin/bash
clear
echo "Please provide access credentials for the 'speedy' yum repository in order to run the haproxy setup script"
echo
read -p "AIOps Repository Username: " AIOPS_USER
export AIOPS_USER
read -p "AIOps Repository Password: " -s AIOPS_PASS
export AIOPS_PASS
echo
bash <(curl -s -k https://\$AIOPS_USER:\$AIOPS_PASS@speedy.moogsoft.com/repo/aiops/haproxy_installer.sh)
_EOF_
bash aiops_repo.sh

  3. Restart Moogfarmd:

    service moogfarmd restart

Configure Opensearch/Elasticsearch heap size

The minimum and maximum JVM heap sizes must be large enough to ensure that Opensearch/Elasticsearch starts.

See Finalize and Validate the Upgrade for more information.

Disable the enhanced Content Security Policy (optional)

Allow access to external domains

Configure Moogsoft Enterprise for use with Safari

Confirm system ulimits

Ensure the 'moogsoft' system user has sufficient limits by running the following command as root:

runuser -l moogsoft -c 'ulimit -n; ulimit -u;'

If either of the values returned are less than 65536, add the following to the /etc/security/limits.conf file as root:

moogsoft	soft    nofile   65536
moogsoft	hard    nofile   65536
moogsoft	soft    nproc	65535
moogsoft	hard    nproc	65535

Verify the installation

Optional - Disable the yum repository

To prevent the Moogsoft Enterprise packages from being upgraded when a system-level 'yum upgrade' command is run, it is recommended to disable the relevant yum repository. The following command assumes the repo file name is aiops.repo:

sed -i 's/enabled.*/enabled=0/' /etc/yum.repos.d/aiops.repo

Change passwords for default users

Install Moogsoft Add-Ons

Moogsoft periodically releases add-ons to extend and enhance the core Moogsoft Enterprise functionality. For example, new Workflow Engine functions, new Workflow Engines, or Integrations tiles. All add-ons releases are cumulative and include the fixes from previous releases.

Once you have finished upgrading or installing Moogsoft Enterprise, you should install the Moogsoft Enterprise add-ons to ensure you have the latest version.

See Install Moogsoft Add-ons for more information on how to install the Moogsoft Enterprise add-ons.
