I've been trying to install PMP on Rocky 9.3 (with SELINUX enabled) but it does not work.

1) should it be installed as root ? under /root/ManageEngine/PMP/ ? 

    Usually it's a bad idea to install under root but ok. You will have problems with permissions of all sorts.

    postgres will not be able to su - into its directory /root/ManageEngine/PMP/pgsql and more.

2) Seems the ManageEngine/PMP/tools/postgres/bin/gettimezone is a 32bit executable

     /root/ManageEngine/PMP/tools/postgres/bin/gettimezone: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.2.5, with debug_info, not stripped

3) When starting up PMP using the pmp.service, after installing it with pmp.sh install two lines jump at me in journal

pmp.service: Changing to the requested working directory failed: Permission denied

pmp.service: Failed at step CHDIR spawning /root/ManageEngine/PMP/bin/wrapper: Permission denied

4) So I tried starting it manually as it would be by the pmp.service scripts

/root/ManageEngine/PMP/bin/wrapper -c /root/ManageEngine/PMP/bin/../conf/wrapper_lin.conf

So the PostgresSQL server can't start,

might be because postgres user cant access things under /root ?

su - postgres
su: warning: cannot change directory to /root/ManageEngine/PMP/pgsql: Permission denied
-bash: /root/ManageEngine/PMP/pgsql/.bash_profile: Permission denied

anybody have a guide on how to install on linux ????
