I just deployed libreNMS last week and everything seem to be working fine until this morning when I attempt to access the WebUI, I saw this:
### Error: Missing dependencies! Run the following command to fix: ./scripts/composer_wrapper.php install --no-dev
When I attempt to execute the suggested command, I got these:
Problem 1

I try to install the missing components and got these:
Error: php70w-common conflicts with php-common-5.4.16-45.el7.x86_64
How is it possible that dependencies will suddenly gone missing?
rm -r /opt/librenms/.pki or chmod -R g+w /opt/librenms/.pki… I’m going to go add an exception for that file because the amount of people posting about this “error” is silly.
It seems like a lot of people set /opt/librenms as the home directory of the librenms users, personally, I would suggest adding cd /opt/librenms in ./bashrc (or equivalent) instead.
FYI, I’m using the vmdk image provided by librenms.org. Does this mean the image is not properly configured with the recommended configuration? Also, after deploying it, it will fail the follow day with the missing dependencies error. I have tried a few time to confirm this. Maybe they should update the image again.
New issue after restoring it from backup. It generate a new network connection, so I have to remove the old one and reconfigure the new network connection to take up the original IP address. However, the web UI shows:
I managed to recovered and notice that the php version in the official vmdk file provided by librenms.org is version 5.4.16 and validate.php suggest that I upgrade.
It looks like the image provided by them has many outdated components with many improper or incomplete configuration as well. The instruction guide on the website given is incomplete too.
Time zone has to be configured not just at the OS level, but also at both the php and database level. rrdcached.service is configured wrongly as well, pointing to /usr/bin/rrdcached instead of /bin/rrdcached. Root password has to be changed and this is not even mentioned on the guide too.
btw, how do I upgrade the php component? After executing these commands:
