Agent configuration file problem in NetXMS version 2.6.300

[Filipp Sudanov]

try deleting /var/log/netxmsd and running
netxmsd -D 6
again.
Wil the error be the same?

[jbriseno]

Hi, Filipp

I deleted the /var/log/netxmsd file

josemb@hpserver1:~$ netxmsd -D 6
Using configuration file "/etc/netxmsd.conf"
FATAL ERROR: Cannot open log file

You are running netxmsd as user "josemb" which does not have write access to /var/log.
Either run netxmsd as root, or change configuration file location.

Hi, Alex I appreciate your time to help me. I repeated the Filipp procedure as root user. The computer screen sent the following messages:

According to systemctl output, netxms is installed in /usr, but it tries to load modules from /usr/local/bin - this looks like you mixed binaries from different versions.
I recommend to clean both versions, then configure and make install again.

Which distro do you use?

[jbriseno]

Hi, Alex. I am using Ubuntu server 18.04. Question: How can I clean both versions?
Thanks in advance.

[Filipp Sudanov]

I would do the following way:
apt remove "netxms*"

Then find and delete the following files on the file system:
libnx*
libnetxms*

And then install netxms again - install  netxms-release package and then netxms-server, netxms-agent and database driver package.

[jbriseno]

Hi, Filipp. Thanks for your sooner reply to my post. I have a Database question: we have a current netXMS database. With this in mind. Do I do

nxdbmgr upgrade or

nxdbmgr init

Thanks in advance

Jose

[Filipp Sudanov]

The database will stand as it is, so there is no need to do init or upgrade. Netxms will just connect to the database that it has in config file.

[jbriseno]

Hi, Filipp, Got it. Thanks

[jbriseno]

Hi, Fillip. I followed your directions to re install the NextXMS on our server.  However, when I tried to install it appeared an error:

Error while loading shared libraries: libnxdb.so.36 when I tried to install the latest netXMS server

Apt command information

sudo apt-get install netxms-server netxms-dbdrv-mysql

The following additional packages will be installed:
  netxms-agent netxms-dbdrv-sqlite3
The following NEW packages will be installed:
  netxms-agent netxms-dbdrv-mysql netxms-dbdrv-sqlite3 netxms-server

Do you know what I did wrong? any comments are wellcome !

[Filipp Sudanov]

Did you manage to find and delete libnx* and libnetxms* files?

Please show the output of these two commands:

ldd /usr/bin/nxagentd
ldd /usr/lib/x86_64-linux-gnu/libnxdb.so.36

Looks like files from netxms-base package are missing - try to re-install it.

Best regards,

[jbriseno]

Hi, Victor I appreciate your sooner reply to my post. I have a question: How can I install the netxms-base package ?

Thanks in Advance

[Filipp Sudanov]

apt install netxms-base

if it's already installed, try removing it first with
apt purge netxms-base

[jbriseno]

Hi, Filipp. First I appreciate your time for help me. Second, Every thing is Ok. However, when

sudo apt-get install netxms-server netxms-dbdrv-pgsql

Additional steps required:

1. Edit default configuration file (/etc/netxmsd.conf) <----- Done !

2. Load database schema

  nxdbmgr init <--- I have a question here. Do I have to do it or I do nxdbmgr upgrade. Because I started netXMS server without this step and It  doesn't work

3. Start daemon with command:

  systemctl start netxms-server

The latest 3 lines of the file /var/log/netxmsd

Hey, Filipp. I found an installation procedure error. I fixed it and the netXMS server is up and running
