Server installation errors

While installing the PEM server on RHEL 8, you might see this error:

[root@etpgxlt firstuser]# dnf install edb-pem

Remove the python3-mod_wsgi package first:

dnf remove python3-mod_wsgi

Then try installing the PEM server again.

Reconfiguring the PEM server

In some situations, you might need to uninstall the PEM server, reinstall it, and then configure the server again. To do so:

Remove the PEM server configuration and uninstall:
```
/usr/edb/pem/bin/configure-pem-server.sh –un
```
Remove the PEM packages:
```
yum erase edb-pem-server
```
Drop the pem database:
```
DROP DATABASE pem
```
Move the certificates from /root/.pem/ to another location:
```
mv /root/.pem/* <new_location>
```
Move the agent.cfg file from /usr/edb/pem/agent/etc/agent.cfg to another location:
```
mv /usr/edb/pem/agent/etc/agent.cfg <new_location>
```
Then, configure the PEM server again:
```
/usr/edb/pem/bin/configure-pem-server.sh
```
