Grafana doesnt start from service but from console

Grafana
1

Hi everybody,

i already looked up the forum, the error message i get was often discussed, but none of the thread helped me out of my problem. At first, im on an unpriviliged debian LXC Container on Proxmox.

I try to get grafana (actual version from apt install) to get running. When i start grafana-server

from /usr/share/grafana

everything runs fine. But trying to start the service with

systemctl start grafana-server

the application doesnt start, systemctl status grafana-server gives me:

systemctl status grafana-server

Im also wondering if the service description could be the problem, where are those variables defined given here:

ExecStart=/usr/share/grafana/bin/grafana server                                     \
                            --config=${CONF_FILE}                                   \
                            --pidfile=${PID_FILE_DIR}/grafana-server.pid            \
                            --packaging=deb                                         \
                            cfg:default.paths.logs=${LOG_DIR}                       \
                            cfg:default.paths.data=${DATA_DIR}                      \
                            cfg:default.paths.plugins=${PLUGINS_DIR}                \
                            cfg:default.paths.provisioning=${PROVISIONING_CFG_DIR}

I could resolve the problem, i had to activate nesting for lxc container and reinstall everything. Now it works.
