Web console installation

[Filipp Sudanov]

Hi!

Did you try to connect from desktop client, not the web one? Did you suceed?

[squeezypiano]

Yes, desktop client is working just fine.

Is anyone able to help, please?  Still cannot get it working.  Here is what I did on Ubuntu 20.04 to install...

wget http://packages.netxms.org/netxms-release-latest.deb
dpkg -i netxms-release-latest.deb

apt-get update

apt-get dist-upgrade -y

apt-get install postgresql postgresql-contrib tomcat9 -y

sudo -u postgres psql

CREATE DATABASE netxms;
CREATE ROLE netxms WITH LOGIN;
\password netxms
GRANT ALL PRIVILEGES ON DATABASE netxms TO netxms;
\q

apt-get install netxms-server netxms-dbdrv-pgsql netxms-agent -y

nano /etc/netxmsd.conf <-- uncomment psql and add password

nxdbmgr init

systemctl enable netxmsd
systemctl restart netxmsd

cd /tmp
wget https://www.netxms.org/download/releases/3.5/nxmc-3.5.90.war
mv nxmc-3.5.90.war /var/lib/tomcat9/webapps/nxmc.war

Hi!

Just tried your installation sequence on fresh ubuntu 20.04, nxmc correctly opens on port 8080

[squeezypiano]

Thanks, but I don't think I have SSL enabled and the page loads fine just will not connect to the service.  When I try to log in I get 'Connection error, connected timed out'.  Does it need SSL enabling?

I had error when tried to connect to 8080 via https. Should just use http.

[squeezypiano]

Ah, yes, OK.  So HTTP loads but gives the connect error when I try to log in.  The server is running and I can connect from the desktop console just not the WebUI.

Just in case, show nxmc log file:
 /var/lib/tomcat9/work/Catalina/localhost/nxmc/eclipse/workspace/.metadata

Try deleting tomcat workspace:
stop tomcat process
delete /var/lib/tomcat9/work folder
start tomcat again

Oh now that's interesting.  Hadn't found that log file but in there it has:

!MESSAGE Server address resolved from NETXMS_SERVER: x.x.x.x

The address being returned is not the address of itself but for the @ record for the machine's domain, which in this case is a public address.  What is it trying to resolve to get that?  As far as I can tell /etc/hosts and DNS are set up correctly.

[Filipp Sudanov]

Seems that you do have a DNS records NETXMS_SERVER or it's in your hosts file. Web console uses it as one of the options for situations when web console in installed on another machine. See here:

[squeezypiano]

I definitely do not have an entry anywhere but by adding it I can now log in to the WebUI.  So does it not attempt local before checking for NETXMS_SERVER or should there always be an entry for NETXMS_SERVER?

[Filipp Sudanov]

It tries several ways, as per documentation, to get server address and takes localhost as last resort. Normally none of these is set. Could be that something changed after you launched the web api on that server.

Thanks so much for the help and guidance, it's much appreciated.  All working happily now and my frustration is over
