ubuntu - 重启elasticsearch失败

Question

我在 ubuntu 版本 14.04 的虚拟机上安装了 elasticsearch 版本 2.3.3。我试图重新启动 elasticsearch 服务，但在重新启动后，我使用 sudo service elasticsearch status 检查了状态，它返回了 * elasticsearch is not running。当我尝试使用 sudo service elasticsearch start 启动它时，它返回 * Starting Elasticsearch Server 但检查状态时发现它没有运行。

我尝试通过输入 /usr/share/elasticsearch/bin/elasticsearch(这是二进制文件的路径)来手动启动它，但一开始我收到以下错误:

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，所以我遵循了 https://github.com/elastic/ansible-elasticsearch/issues/58 中的建议通过创建符号链接(symbolic link): sudo ln -s/etc/elasticsearch//usr/share/elasticsearch/config

之后，通过 /usr/share/elasticsearch/bin/elasticsearch 运行 Elasticsearch 时出现以下错误:

Exception in thread "main" ElasticsearchException[Failed to load logging configuration]; nested: AccessDeniedException[/usr/share/elasticsearch/config];
Likely root cause: java.nio.file.AccessDeniedException: /usr/share/elasticsearch/config

当以 root (sudo/usr/share/elasticsearch/bin/elasticsearch) 身份尝试时，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。我在另一台虚拟机上遇到了完全相同的问题(第一个异常(exception) - 未找到日志记录配置)并尝试通过创建路径 /usr/share/elasticsearch/config 并复制配置文件来解决它(elasticsearch.yml 和 logging.yml)。之后我又遇到了第二个问题(以普通用户身份运行 - 访问被拒绝并且不允许以 root 身份运行)。

有人知道这个问题吗？我们将不胜感激!

就我而言，以下链接有帮助:

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