Hi everybody!
I just finished to install Librenms in my clean CentOS7 by following carefuily step by step this guide: https://docs.librenms.org/Installation/Installation-CentOS-7-Apache/
In the beginning everyting works just fine, I was even capable to add two devices to my monitoring system whit good results, but one reboot later, I find “Error connecting to database SQLSTATE[HY000] [2002] No such file or directory” in my navegator.
I went to the console to see:
"[root@localhost ~]# systemctl status mariadb
● mariadb.service - MariaDB database server
Loaded: loaded (/usr/lib/systemd/system/mariadb.service; disabled; vendor preset: disabled)
Active: inactive (dead)
[root@localhost ~]# systemctl start mariadb
Job for mariadb.service failed because the control process exited with error code. See “systemctl status mariadb.service” and “journalctl -xe” for details.
