2.2.0版本es在centos6.5 x64上自动关闭 #47

Closed ZhangShufan15 closed 8 years ago

ZhangShufan15 commented 8 years ago

我下载的是2.2.0版本的rtf，安装在centos6.5 x64上，同时用plugin install mobz/elasticsearch-head安装了head。

在es上有一个索引，索引中包含2个类型，1个分片，0个备份。数据量很小，总共500条，200k数据。

es启动后，每隔一段时间，第一次是2天，后来都是半天不到，就自动关闭了。查看了/var/log/messages里面没有异常杀死进程的信息。

看es的日志，能够看到输出了stopping stopped closing closed ，但是没有关闭的原因。以下是最后的日志输出：

请问，这可能是什么原因造成的，谢谢？

是不是没有设置 java 的堆栈大小ES_HEAP_SIZE

ZhangShufan15 commented 8 years ago

确实没有设置，这个地方是最好设置么？

后来发现问题可能的原因是我再远程ssh，登录的centos，然后用./elasticsearch 启动的，没有加-d 让他后台启动，这样的话一旦关闭了本机的命令行窗口，elasticsearch就会shutdown，我再跟踪一段时间看看。

medcl commented 8 years ago

调大一点看看吧，可能内存不够用

ZhangShufan15 commented 8 years ago

好的，我再跟一段时间

Steven-Z-Yang commented 8 years ago

基本上就是你没有加-d的原因
