如何从Ubuntu上删除Elasticsearch? [英] How to remove Elasticsearch from Ubuntu?

问题描述

我认为我已经从计算机上删除了elasticsearch，但仍然有一些疑问.

I think that I already removed elasticsearch from my computer, and still I have some doubts.

当我键入:

$ service elasticsearch status

我得到:

elasticsearch.service已加载:找不到(原因:没有此类文件或目录)活动:自星期三2017-08-09以来失败(结果:退出代码)01:08:18 PDT；38min ago Main PID:73249(code = exited，状态= 1/失败)

但是，当我键入:

$ service helloworld status 

我的话要简短得多:

helloworld.service已加载:找不到(原因:没有此类文件或

helloworld.service Loaded: not-found (Reason: No such file or

目录)有效:无效(无效)

directory) Active: inactive (dead)

我已经使用以下命令删除了Elasticsearch:

I already removed Elasticsearch by using the command:

sudo apt-get --purge autoremove elasticsearch

，看起来仍然像elasticsearch存在.

and it still looks like elasticsearch exists.

推荐答案

卸载后，似乎已经遗忘了Elasticsearch /etc/init.d/elasticsearch 的启动脚本.因此，将其删除，应该是最后一步.

It seems that the startup script for elasticsearch /etc/init.d/elasticsearch has been left behind after the uninstallation. So, remove it and should be the final step.

您还可以尝试使用以下命令查找是否还有其他剩余的脚本，文件或文件夹:

You can also try to locate if there are any other left scripts, files or folders using the following command:

# locate elasticsearch

然后按照弹性论坛中的说明删除它们这里.

And then remove those as explained in elastic forums here.

请注意，要使 locate 能够在任何地方都可以看到，您需要以root用户身份启动命令.

Notice that to enable locate to look everywhere you need to launch the command as root.
