Uninstall Moogsoft Onprem

1. Stop all core Moogsoft Onprem services:

service moogfarmd stop
service logfilelamd stop
service restlamd stop
service socketlamd stop
service trapdlamd stop

2. Stop any additional moog_farmd or lam instances running as services.

service <service name> stop

3. As a precaution, forcibly kill any remaining core Moogsoft Onprem processes:

kill -9 $(ps -ef|grep java|grep lam|awk '{print $2}') 2>/dev/null
kill -9 $(ps -ef|grep java|grep moog_farmd|awk '{print $2}') 2>/dev/null

4. Stop all supporting services:

service nginx stop
service opensearch stop

1. Uninstall Core Moogsoft Onprem Packages

yum remove $(rpm -qa|grep moogsoft)

If the above command produces errors such as 'Error in PREUN scriptlet' then the following command can be run to bypass script errors:

2. Remove Core Moogsoft Onprem Directories

rm -rf /usr/share/moogsoft
rm -rf /var/lib/moogsoft
