- Configure Nginx server blocks by running the following command:
sudo cp /opt/librenms/librenms.nonroot.nginx.conf /etc/nginx/conf.d/librenms.conf sudo systemctl restart nginx
- Finally, configure SELinux by running the following command:
sudo setsebool -P httpd_can_sendmail=1 sudo setsebool -P httpd_execmem=1 sudo setsebool -P httpd_unified=1 sudo setsebool -P httpd_can_network_connect=1 sudo setsebool -P httpd_read_user_content=1 sudo setsebool -P httpd_can_connect_ldap=1 sudo setsebool -P httpd_can_network_relay=1 sudo setsebool -P httpd_can_connect_db=1 sudo setsebool -P httpd_use_nfs=1 sudo setsebool -P httpd_enable_homedirs=1
