The following steps are only necessary if you plan to encrypt OLAP.
Add the certificate line and change the host in <Install_path>/core-Linux-x86_64/etc/palo_config.xml:
<server>
<host>www.example.com</host>
<port>7777</port>
</server>
<certificate path="<path to certificate>"/>
In <Install_path>/core-Linux-x86_64/etc/macro_engine_config.xml add the following certificate line:
<ini_directives>
...
jedox.phppalo.trust_file="<path to certificate>"
...
</ini_directives>
