Copy the Percona install_percona_nodes.sh install script and RPM install files to all servers that will house a database node.

Copy the tar.gz files to all servers that will run Moogsoft Onprem components.

Copy the HA Proxy RPM to the servers that will have the Core, UI and LAM server roles.

See Server Roles for more information on the Core, UI and LAM server roles.

Create two directories to house the repositories. For example:

sudo mkdir -p /media/localRPM/BASE/

sudo mkdir -p /media/localRPM/ESR/

Extract the two tarball files into separate directories and move the HA Proxy RPM to /media/localRPM/BASE/. For example:

tar xzf *-MoogsoftBASE8_offline_repo.tar.gz -C /media/localRPM/BASE/

tar xzf *-MoogsoftESR_9.1.0_offline_repo.tar.gz -C /media/localRPM/ESR/

mv haproxy*rpm  /media/localRPM/BASE/

Back up the existing /etc/yum.repos.d directory. For example:

mv /etc/yum.repos.d /etc/yum.repos.d-backup

Disable the RHEL system repository monitor:

subscription-manager config --rhsm.manage_repos=0

Create an empty /etc/yum.repos.d directory. For example:

mkdir /etc/yum.repos.d

Create a local.repo file ready to contain the local repository details:

vi /etc/yum.repos.d/local.repo

Edit local.repo and configure the baseurl paths for BASE and ESR to point to the your directories. For example:

[BASE]
name=Moogsoft-$releasever - BASE
baseurl=file:///media/localRPM/BASE/RHEL
gpgcheck=0
enabled=1
module_hotfixes=true
[ESR]
name=Moogsoft-$releasever - ESR
baseurl=file:///media/localRPM/ESR/RHEL
gpgcheck=0
enabled=1
module_hotfixes=true

Clean the Yum cache:

yum clean all

Verify that Yum can detect the newly created repositories. For example:

yum info "moogsoft-*"

yum -y install percona_dependencies/*.rpm
yum -y install percona-xtradb-cluster-*.rpm percona-xtrabackup-*.rpm

Set SELinux to permissive mode or disable it completely. For example, to set SELinux to permissive mode:

setenforce 0

If you want to disable SELinux at boot time, edit the file /etc/sysconfig/selinux.
