Can you please check the contents of /etc/systemd/system/default.target.wants/gmd.service?

It should be exactly as follows:

[Unit]
Description=gmd - galera manager daemon
After=network.target

[Service]
EnvironmentFile=/etc/default/gmd
User=gmd
Group=gmd
LimitNOFILE=65536
Restart=on-failure
Type=simple
ExecStart=/usr/bin/gmd run $ARGS

[Install]
WantedBy=default.target

If it's so, check please if you have /etc/default/gmd in place and /usr/bin/gmd as well.

I noted that you use influxdb outside of gmd installation. This is unsupported currently. You should use a bundled influx installation. Also, the next version of the installer will be able to fix a broken installation. But currently to fix it manually, you should create a missing file /etc/default/gmd with the following content:

GMD_CONFIG_DIR=/var/lib/gmd
GMD_LOGS_DIR=/var/log/gmd
INFLUXDB_URL=http://INFLUX_USER:INFLUX_PASSWORD@GMD_NGINX_DOMAIN_OR_IP:8081

Note that if you use https, then the port must be 9091.

This should be fixed now in the new version of the installer. You can even run it on over an existing installation, it will reconfigure/repare it accordingly.

This should be fixed in the latest version of gm-installer.
