Question

我在带有ubuntu版本14.04的虚拟机上安装了elasticsearch版本2.3.3。我尝试重新启动elasticsearch服务，但在重新启动后，我使用sudo service elasticsearch status检查了状态，并返回* elasticsearch is not running。当我尝试使用sudo service elasticsearch start启动时，它会返回* Starting Elasticsearch Server，但检查状态后会发现它没有运行。

我尝试通过输入/usr/share/elasticsearch/bin/elasticsearch（这是二进制文件的路径）手动启动它，但在开始时我收到以下错误：

Exception in thread "main" ElasticsearchException[Failed to load logging configuration]; nested: NoSuchFileException[/usr/share/elasticsearch/config];

错误告诉它无法找到日志记录配置，因此我通过创建符号链接来遵循https://github.com/elastic/ansible-elasticsearch/issues/58中的建议： sudo ln -s /etc/elasticsearch/ /usr/share/elasticsearch/config

之后，当通过/usr/share/elasticsearch/bin/elasticsearch进行弹性搜索时，我收到以下错误：

Exception in thread "main" ElasticsearchException[Failed to load logging configuration]; nested: AccessDeniedException[/usr/share/elasticsearch/config];

以root用户身份（sudo /usr/share/elasticsearch/bin/elasticsearch）时，我收到以下错误：

Exception in thread "main" java.lang.RuntimeException: don't run elasticsearch as root.
    at org.elasticsearch.bootstrap.Bootstrap.initializeNatives(Bootstrap.java:93)
    at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:144)

    at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35)
Refer to the log for complete error details.

这不是我第一次遇到这个问题。我在另一个虚拟机上面临完全相同的问题（第一个例外 - 未找到日志记录配置）并试图通过创建路径/usr/share/elasticsearch/config并将配置文件（elasticsearch.yml和logging.yml）复制到它。之后我又面临第二个问题（以普通用户身份运行 - 拒绝访问并且不允许以root身份运行。）

有人对这个问题有所了解吗？任何帮助都会受到欢迎！

Answer 1

您是否尝试过以下操作：

1）创建目录

$ mkdir -p /usr/share/elasticsearch/config/scripts

2）复制日志和配置文件

$ cp /etc/elasticsearch/elasticsearch.yml /user/share/elasticshare/config
$ cp /etc/elasticsearch/logging.yml /user/share/elasticshare/config

3）更改权限或更改这些文件的所有权。

$ sudo chmod g+rwx /usr/share/elasticsearch/config/elasticsearch.yml /usr/share/elasticsearch/config/logging.yml 
$ sudo chmod o+rwx /usr/share/elasticsearch/config/elasticsearch.yml /usr/share/elasticsearch/config/logging.yml

Answer 2

对于我来说，以下链接有所帮助：

ln -s /etc/elasticsearch/ /usr/share/elasticsearch/config

无法重新启动elasticsearch
