tomcat - OS启动时如何启动Fuseki？

Question

是否有一种在操作系统启动时启动 Fuseki 的简单方法，或多或少就像我们可以从/etc/init.d/tomcat7 start或/etc/init.d/elasticsearch start启动 Tomcat 或 ElasticSearch 实例一样？

据我所见，Fuseki 似乎没有状态方法，而且它似乎也没有类似于/etc/init.d/技巧的东西。

实际上，Fuseki 附带了一个脚本，它完全可以满足您的要求。我认为这只是将fuseki脚本放在init.d目录中的问题。发行版中的fuseki脚本采用{start|stop|restart|status}参数。这是从命令行使用的样子：

$ ./fuseki
Usage: fuseki {start|stop|restart|status}
$ ./fuseki status
Fuseki is not running
$ ./fuseki start
Starting Fuseki: Redirecting Fuseki stderr/stdout to .../jena-fuseki-1.1.2-SNAPSHOT/log/stderrout.log
STARTED Fuseki Mon Oct 27 10:02:59 EDT 2014
PID=3752
$ ./fuseki status
Fuseki is running with pid: 3752
$ ./fuseki restart
Stopping Fuseki: OK
Starting Fuseki: Redirecting Fuseki stderr/stdout to .../jena-fuseki-1.1.2-SNAPSHOT/log/stderrout.log
STARTED Fuseki Mon Oct 27 10:03:09 EDT 2014
PID=3813
$ ./fuseki status
Fuseki is running with pid: 3813
$ ./fuseki stop
Stopping Fuseki: OK
$ ./fuseki status
Fuseki is not running

它实际上是为此目的而设计的；查看我们看到的来源：

# Startup script for Fuseki under *nix systems (works with cygwin too)
#
# Configuration
# -------------
# Default values are loaded from /etc/default/fuseki, if it exists.

⋮

# FUSEKI_HOME
#   Where Fuseki is installed.  If not set, the script will try
#   to guess it based on the script invokation path.
#
# FUSEKI_RUN
