配置 Fuseki 服务。
sudo vi /etc/systemd/system/fuseki.service
fuseki.service 的内容如下：
[Unit]
Description=Fuseki
[Service]
# Edit environment variables to match your installation
Environment=FUSEKI_HOME=/home/garden-user/etc/fuseki
Environment=FUSEKI_BASE=/home/garden-user/etc/fuseki/run
# Edit the line below to adjust the amount of memory allocated to Fuseki
Environment=JVM_ARGS=-Xmx4G
# Edit to match your installation
ExecStart=/home/garden-user/etc/fuseki/fuseki-server
# Run as user "fuseki"
User=fuseki
Restart=on-abort
# Java processes exit with status 143 when terminated by SIGTERM, this
# should be considered a successful shutdown
SuccessExitStatus=143
### By default, the service logs to journalctl only.
### If additional logging to a file is required, uncomment the following three lines
# StandardOutput=syslog
# StandardError=syslog
# SyslogIdentifier=fuseki
### This logs to syslog. If, e.g., rsyslogd is used, you can provide a file
### /etc/rsyslog.d/fuseki.conf, consisting of the following two lines (uncommented)
### if $programname == 'fuseki' then /var/log/fuseki/stderrout.log
### if $programname == 'fuseki' then stop
[Install]
