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

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 -

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 -

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;

yum install *.rpm

Download the Percona database installer 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

Execute the .bashrc file:

source ~/.bashrc

To allow users to configure an ElasticSearch cluster, the vm.max_map_count property must be at least 262144. Check this property by running:

sysctl -n vm.max_map_count

If the value is less than 262144, add the following line to the end of the /etc/sysctl.conf file (requires root permissions):

vm.max_map_count = 262144

Ensure the current user, or the user that will be running the Moogsoft processes, has sufficient ulimits by running the following commands as that user:

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
