无法在Ubuntu 16上安装Elasticsearch的x-pack插件

Question

我首先得到了这个错误：

ubuntu@server:/usr/share/elasticsearch$ sudo bin/plugin install x-pack
Exception in thread "main" org.elasticsearch.env.FailedToResolveConfigException: Failed to resolve config path ["/usr/share/elasticsearch/config/elasticsearch.yml"], tried file path ["/usr/share/elasticsearch/config/elasticsearch.yml"], path file ["/usr/share/elasticsearch/config"/"/usr/share/elasticsearch/config/elasticsearch.yml"], and classpath
    at org.elasticsearch.env.Environment.resolveConfig(Environment.java:291)
    at org.elasticsearch.node.internal.InternalSettingsPreparer.prepareSettings(InternalSettingsPreparer.java:95)
    at org.elasticsearch.plugins.PluginManager.main(PluginManager.java:396)

并使用this workaround将命令打印到控制台并手动运行。

然后，我尝试运行"sudo bin/plugin install file:///home/ubuntu/x-pack-5.4.1.zip"：“命令输出

如果我尝试"sudo bin/plugin install x-pack“的输出，我得到这个错误：

-> Installing x-pack...
Trying https://github.com/null/x-pack/archive/master.zip...

Answer 1

您在安装x-pack时使用了错误的命令，导致该命令ubuntu@server:/usr/share/elasticsearch$ sudo bin/elasticsearch-plugin install x-pack

并且它会自动安装x-pack插件，你可以使用--batch选项，没有运行时提示来允许java类和权限。
