在OpenSuse上运行Cassandra作为服务

Question

我试图在OpenSuse上运行Cassandra作为服务（Leap 42.1）。

我已经尝试使用apache-cassandra-2.1.11-bin.tar.gz进行安装，然后从https://gist.github.com/sgomezvillamor/5458309复制/etc/init.d/cassandra。然而，启动脚本是不是专为OpenSuse当中，作为SYSTEM.LOG说：

/etc/init.d/cassandra：行30：守护：命令未找到。

如果会有一个能够正确创建脚本的安装程序，那么问题就不存在了，就像其他一些操作系统一样。搜索一个安装包，我发现http://www.datastax.com/dev/blog/announcing-rpms-cassandra，并试图在rpm.riptano.com上查找rpm，但我无法确定哪一个可以在OpenSuse中工作。

哪些软件包可以用于OpenSuse？或者，我应该如何修改Suse的启动脚本来追踪它？

Answer 1

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

我不知道这是否将让你100％的有系统的OpenSUSE，但应该让你非常接近。

我得到了它与/etc/init.d/cassandra文件的工作：

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

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