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

Enable only the aducid-media section

[aducid-media]
name=aducid $releasever
baseurl=file:///media/ADUCID/repository/el$releasever/$basearch/
gpgcheck=0
enabled=1

Copy your installation files to the same directory, as specified above (/media/ADUCID)

yum clean all  
# if the following is OK …
yum update aducid-installer
# … then do the others 
yum update aducid-aaa aim aducid-proof 

• You will probably need to replace newly installed file /opt/aaa/conf/aducid-aaa.conf with the file, you saved in previous steps
• Check also the /opt/tomcat/conf/ADUCID.properties file

systemctl start tomcat9.service
tail -f /opt/tomcat/logs/catalina.out
#
systemctl start aducid-aaa.service
systemctl -l status aducid-aaa.service
#
systemctl start httpd.service
systemctl -l status httpd.service
