Error Installing

Help

Hello,

I Have issue when installing librenms on centos 7 on step 2.
The error are : Could not connect to database, check logs/librenms.log.
I’m sure that user&pass mysql is correct.

When i see these log it says,
[2018-09-12 08:54:01] production.ERROR: PDOException: SQLSTATE[HY000] [2002] No such file or directory in /opt/librenms/vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php:68

Any clue how to fix it ?

You should not get errors like that, must be a bug. It seems your credentials are incorrect.

You clear your browser cookies and try again with install.php or you can create config.php by hand and run ./build-base.php and ./adduser.php.

Thanks for your support.
I think i found the issue on /etc/hosts

After i ./adduser it seems that i could not login to librenms
Any thing can i do ?

4

run ./validate.php and check the output. Or delete config.php and go through install.php again.

5

I’m sorry … it seems that i’m unable to use install.php again
After ./validate.php my account don’t have permission to add device event on level 10.

6

Add a new user with level 10, you cannot edit a user from the CLI. Then once logged in change your user to level 10.

hi,

nothing i can do after login, permission not allowed

8

So, how many users have you added now? It should be at least 2.

Thanks for your support, i think i have another issue then.
It seems that device that i add not showing anything … in fact i have warning devices in not polled.
