我正在尝试在 OpenSuse（Leap 42.1）上将 Cassandra 作为服务运行。

我尝试使用 apache-cassandra-2.1.11-bin.tar.gz 安装，然后从https://gist.github.com/sgomezvillamor/5458309复制 /etc/init.d/cassandra 。然而，启动脚本并不是为 OpenSuse 设计的，正如 system.log 所说：

/etc/init.d/cassandra：第 30 行：守护进程：找不到命令。

如果有一个安装程序可以正确创建脚本，那么问题就不会存在，就像其他一些操作系统一样。搜索安装包时，我找到了http://www.datastax.com/dev/blog/announcing-rpms-cassandra并试图在 rpm.riptano.com 中寻找一个 rpm，但我不知道哪个可以工作OpenSuse。

哪些软件包适用于 OpenSuse？或者，我应该如何修改 Suse 的启动脚本呢？

我让它与 /etc/init.d/cassandra 文件一起工作：

#
# /etc/init.d/cassandra
#
# Startup script for Cassandra
# 
# chkconfig: 2345 20 80
# description: Starts and stops Cassandra

#. /etc/rc.d/init.d/functions

我会检查这些适用于 Cassandra 2.1 的说明：Installing DataStax Community 2.1 on RHEL-based systems。

我不确定这是否会让你在 OpenSUSE 系统上 100% 到达那里，但应该让你非常接近。
