为什么Elasticsearch 8x。从互动开始，但不是作为服务Ubuntu 20.04的服务？
在Ubuntu 16.04上解决此问题的提示似乎不起作用。 这是指向各种技巧领域之一的链接： https：//discuss.lastic。 co/t/cant-start-elasticsearch-with-ubuntu-16-04/48730/28
缺少一些东西 - 我在Ubuntu 20.04上，ES V8.X，Logstash 8.x，Kibana 8。 x。手动启动效果很好。注意：
根本没有“ etc/default/elasticsearch”文件；我创建了一个： （是的，用户确实存在；所有所有权都已更改 所有文件）
＃这是我创建的“/etc/default/elasticsearch”文件： es_user =“ elasticsearch” es_group =“ elasticsearch”
start_daemon =“ true”＆lt ;--这甚至需要Beyone Ubuntu 16吗？ restart_on_upgrade =“ true”
我认为我是通过deb .tar软件包安装的，而不是通过apt
安装的安装的。但是只有“交互式” - 那么我们如何解决不存在服务的事实？我尝试了所有相关的技巧和所有其他建议。 - ??
elasticsearch@es-vm：/etc/ect/默认$服务elasticsearch状态 单位Elasticsearch.Service找不到。
root@es-vm：/etc/ext/default＃服务elasticsearch start 无法启动Elasticsearch.Service：单位Elasticsearch.Service找不到。
任何帮助将不胜感激。提前致谢！
The tip for fixing this issue on Ubuntu 16.04 does not seem to work.
Here's a link to one of the areas of various tips:
https://discuss.elastic.co/t/cant-start-elasticsearch-with-ubuntu-16-04/48730/28
There's something missing - I'm on ubuntu 20.04, and ES v8.x, logstash 8.x, kibana 8.x. Manually starting works great. Notes:
There was NO "etc/default/elasticsearch" file at all; I created one:
(and yes, the user & group do exist; and all ownership has been changed on
all the files)#Here's the "/etc/default/elasticsearch" file I created:
ES_USER="elasticsearch"
ES_GROUP="elasticsearch"START_DAEMON="true" <-- Is this even needed beyone Ubuntu 16?
RESTART_ON_UPGRADE="true"I think I installed via the deb .tar packages and not via APT
It runs GREAT; but only "interactively" - so how do we fix the fact that no service exists? I've tried all the related tips, and all other recommendations. - ??
elasticsearch@ES-VM:/etc/default$ service elasticsearch status
Unit elasticsearch.service could not be found.root@ES-VM:/etc/default# service elasticsearch start
Failed to start elasticsearch.service: Unit elasticsearch.service not found.
Any help would be greatly appreciated. Thanks in advance!

如果您通过焦油文件安装，那么系统上没有其他任何其他文件，没有默认文件，没有服务文件。这是一种非常典型的Linux方法，可以通过TGZ“安装”任何内容，因为它类似于“ UNZIP”，
如果您想开始使用该服务，然后使用deb package或apt repo，否则您将需要创建自己的自己服务文件
if you installed via the tar file then there's nothing else that is created on the system, no defaults file, no service file. that's a pretty typical linux approach to "installing" anything via a tgz, as it's akin to an "unzip"
if you want to start this as a service then use the deb package or the apt repo, or you will need to create your own service file
