Moogsoft AIOps v7.3.x - Tarball pre-installation steps

You must perform certain preparatory tasks before you install Moogsoft AIOps v7.3.x.

Follow these steps if you do not have root access to the machine or machines on which you will install Moogsoft AIOps.

For RPM pre-installation steps, see v7.3.x - RPM pre-installation steps.

For Offline RPM pre-installation steps, see v7.3.x - Offline RPM pre-installation steps.

Before you begin

Before you begin to prepare for the installation, verify the following:

  • You have a CentOS 7 / RHEL 7 system on which to install Moogsoft AIOps.

  • You have removed any existing environment variables such as $MOOGSOFT_HOME from previous installations.

  • You have identified the Linux user you will use to perform the installation.

  • Optional: Ask an administrator to set the ulimit maximum for open files and max user processes for the installation user. This requires root privileges. For example, on a busy system you could increase both to 65535.

  • You have selected a working directory in which to run the installation. The installation directory requires a minimum of 7Gb, and more if you are storing the Percona database in the installation directory, to allow for database and Elasticsearch artefacts and log file growth.

  • You have credentials to connect to the Moogsoft "speedy" Yum repository.

  • You are familiar with the supported versions of third party software, as outlined in Moogsoft AIOps 7.3.0 Supported Environments.

  • Ports 8443 and 8080 are open on your server.

  • You are running OpenSSL v1.0.2 or later.

Pre-installation steps

Before you perform a Tarball installation of Moogsoft AIOps v7.3.x, complete the following tasks on the server on which you will install Moogsoft AIOps:

  1. Install Kernel Asynchronous I/O (AIO) Support for Linux. For example:

    mkdir -p ~/install/libraries/ && cd ~/install/libraries/ && \
curl -L -O http://mirror.centos.org/centos/7/os/x86_64/Packages/libaio-0.3.109-13.el7.x86_64.rpm && \rpm2cpio ./libaio-0.3.109-13.el7.x86_64.rpm | cpio -idmv && \
rm -f ./libaio-0.3.109-13.el7.x86_64.rpm && \
rm -f ~/install/libraries/lib64/libaio.so.1 && \
ln -s ~/install/libraries/lib64/libaio.so.1.0.1 ~/install/libraries/lib64/libaio.so.1 && \echo "export LD_LIBRARY_PATH=`pwd`/lib64:\$LD_LIBRARY_PATH" >> ~/.bashrc && \
source ~/.bashrc

cd -

  2. Install libgfortran. For example:

    mkdir -p ~/install/libraries/ && cd ~/install/libraries/
for PACKAGE in libquadmath-4.8.5-39.el7.x86_64.rpm libgfortran-4.8.5-39.el7.x86_64.rpm; do
    curl -L -O http://mirror.centos.org/centos/7/os/x86_64/Packages/$PACKAGE && \
    rpm2cpio $PACKAGE | cpio -idmv && \
    rm -f $PACKAGE
done
echo "export LD_LIBRARY_PATH=$(pwd)/usr/lib64:\$LD_LIBRARY_PATH" >> ~/.bashrc && \
source ~/.bashrc

cd -

  3. Install Percona dependencies. This step requires root privileges:

    curl -L -O http://repo.percona.com/percona/yum/release/7/RPMS/x86_64/qpress-11-1.el7.x86_64.rpm;

for PACKAGE in libev-4.15-7.el7.x86_64.rpm perl-5.16.3-294.el7_6.x86_64.rpm perl-Pod-Escapes-1.04-294.el7_6.noarch.rpm perl-libs-5.16.3-294.el7_6.x86_64.rpm perl-macros-5.16.3-294.el7_6.x86_64.rpm xinetd-2.3.15-13.el7.x86_64.rpm perl-Carp-1.26-244.el7.noarch.rpm perl-Compress-Raw-Bzip2-2.061-3.el7.x86_64.rpm perl-Compress-Raw-Zlib-2.061-4.el7.x86_64.rpm perl-DBD-MySQL-4.023-6.el7.x86_64.rpm perl-DBI-1.627-4.el7.x86_64.rpm perl-Data-Dumper-2.145-3.el7.x86_64.rpm perl-Digest-1.17-245.el7.noarch.rpm perl-Digest-MD5-2.52-3.el7.x86_64.rpm perl-Encode-2.51-7.el7.x86_64.rpm perl-Exporter-5.68-3.el7.noarch.rpm perl-File-Path-2.09-2.el7.noarch.rpm perl-File-Temp-0.23.01-3.el7.noarch.rpm perl-Filter-1.49-3.el7.x86_64.rpm perl-Getopt-Long-2.40-3.el7.noarch.rpm perl-HTTP-Tiny-0.033-3.el7.noarch.rpm perl-IO-Compress-2.061-2.el7.noarch.rpm perl-Net-Daemon-0.48-5.el7.noarch.rpm perl-PathTools-3.40-5.el7.x86_64.rpm perl-PlRPC-0.2020-14.el7.noarch.rpm perl-Pod-Perldoc-3.20-4.el7.noarch.rpm perl-Pod-Simple-3.28-4.el7.noarch.rpm perl-Pod-Usage-1.63-3.el7.noarch.rpm perl-Scalar-List-Utils-1.27-248.el7.x86_64.rpm perl-Socket-2.010-4.el7.x86_64.rpm perl-Storable-2.45-3.el7.x86_64.rpm perl-Text-ParseWords-3.29-4.el7.noarch.rpm perl-Time-HiRes-1.9725-3.el7.x86_64.rpm perl-Time-Local-1.2300-2.el7.noarch.rpm perl-constant-1.27-2.el7.noarch.rpm perl-parent-0.225-244.el7.noarch.rpm perl-podlators-2.5.1-3.el7.noarch.rpm perl-threads-1.87-4.el7.x86_64.rpm perl-threads-shared-1.43-6.el7.x86_64.rpm socat-1.7.3.2-2.el7.x86_64.rpm rsync-3.1.2-6.el7_6.1.x86_64.rpm lsof-4.87-6.el7.x86_64.rpm 
do
	curl -L -O http://mirror.centos.org/centos/7/os/x86_64/Packages/${PACKAGE};
done;
yum install *.rpm

  4. Install Percona on all servers that will house a database node. The script configures multiple nodes to run as a cluster. A single node is also supported. Substitute your "speedy" Yum repo user credentials:

    cat > aiops_repo.sh << _EOF_
#!/bin/bash
clear
echo "Please provide access credentials for the 'speedy' yum repository in order to run the Percona setup script"
echo
read -p "AIOps Repository Username: " AIOPS_USER
export AIOPS_USER
read -p "AIOps Repository Password: " -s AIOPS_PASS
export AIOPS_PASS
curl -L -O https://\$AIOPS_USER:\$AIOPS_PASS@speedy.moogsoft.com/repo/aiops/install_percona_nodes_tarball.sh 2>/dev/null
echo
_EOF_
bash aiops_repo.sh

    Now run the script:

    bash install_percona_nodes_tarball.sh

    The script guides you through the installation process. To configure a single database node on the same server as Moogsoft AIOps, 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.

  5. Execute the .bashrc file:

    source ~/.bashrc

The pre-installation steps are now complete. To continue with the Moogsoft AIOps installation, see v7.3.x - Tarball installation.
