Question

我刚在服务器上安装了Cassandra

Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux

按照DataStax上的说明进行操作。建议使用Init。

启动Cassandra

$ sudo service cassandra start (dies)

但是，我的过程会在一段时间后死掉。但奇怪的是，我可以通过直接运行Cassandra而没有任何问题来启动它。

$ cassandra (no problem!)

我检查了/ var / log / cassandra中的Cassandra日志，但没有错误。我做错了什么？

Answer 1

尝试从以下位置更改init脚本的头部：

#! /bin/sh

为：

#! /bin/sh -x

然后通过init脚本重启服务（/etc/init.d/cassandra restart）并检查输出，可能有错误

Answer 2

我遇到了这个问题，所以即使这个问题确实很老，也要写下这个解决方案。

我已经修改了cassandra.yaml文件（更新了端口和一些内容），然后该服务便无法启动。它始终显示活动（退出）状态，并且任何日志中都没有任何内容。

事实证明，该服务需要强制重新加载一次，以确保重新读取所有配置文件。

sudo service cassandra force-reload

此后，您应该能够使用service或systemctl照常控制服务。

sudo service cassandra status
sudo systemctl status cassandra
sudo systemctl stop cassandra
sudo systemctl start cassandra
sudo systemctl restart cassandra

无法通过Init服务启动Cassandra。但可以从直接运行$ cassandra开始
