Elasticsearch  目录

如果只想快速安装 IK  ,本教程管用。下面看经过。

简介:

  • 下面讲有我已经打包并且编辑过的 zip 包,你可以在下面下载即可。
  • 当前讲解的 IK 分词器  包的 version 为 1.8。

一、下载 zip 包。

    下面有附件链接【ik-安装包.zip】,下载即可。

二、上传 zip 包。

    下载后解压缩,如下图。

打开修改修改好后打成 zip 包。

# 'elasticsearch.version' version of elasticsearch compiled against# You will have to release a new version of the plugin for each new# elasticsearch release. This version is checked when the plugin# is loaded so Elasticsearch will refuse to start in the presence of# plugins with the incorrect elasticsearch.version.#把这个版本号改成你对应的版本即可,如你的版本是 2.2.0,就改成 2.2.0elasticsearch.version=2.0.0
/elasticsearch-2.0.0/plugins

在 plugins/目录下上传,并且解压缩。此处注意目录结构必须是这样,如下图:

三、启动测试

    呃,我们发现报错了。

[elasticsearch@iZ25x3wjytdZ elasticsearch-2.0.0]$ ./bin/elasticsearch[2016-03-01 10:32:02,958][INFO ][node                     ] [Landslide] version[2.0.0], pid[11109], build[de54438/2015-10-22T08:09:48Z][2016-03-01 10:32:02,959][INFO ][node                     ] [Landslide] initializing ...Exception in thread "main" java.lang.IllegalStateException: Unable to initialize pluginsLikely root cause: java.nio.file.FileSystemException: /home/elasticsearch/es/elasticsearch-2.0.0/plugins/ik.zip/plugin-descriptor.properties: Not a directory        at sun.nio.fs.UnixException.translateToIOException(UnixException.java:91)        at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:102)        at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:107)        at sun.nio.fs.UnixFileSystemProvider.newByteChannel(UnixFileSystemProvider.java:214)        at java.nio.file.Files.newByteChannel(Files.java:317)        at java.nio.file.Files.newByteChannel(Files.java:363)        at java.nio.file.spi.FileSystemProvider.newInputStream(FileSystemProvider.java:380)        at java.nio.file.Files.newInputStream(Files.java:108)        at org.elasticsearch.plugins.PluginInfo.readFromProperties(PluginInfo.java:86)        at org.elasticsearch.plugins.PluginsService.getPluginBundles(PluginsService.java:306)        at org.elasticsearch.plugins.PluginsService.(PluginsService.java:112)        at org.elasticsearch.node.Node.(Node.java:144)        at org.elasticsearch.node.NodeBuilder.build(NodeBuilder.java:145)        at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:170)        at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:270)        at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35)

一看我们就知道,他去找 plugins/ik.zip 下的配置文件对吧。

解决方案是把这个 ZIP 包删除即可。

删除后再次启动。

[elasticsearch@iZ25x3wjytdZ elasticsearch-2.0.0]$ ./bin/elasticsearch[2016-03-01 10:32:02,958][INFO ][node                     ] [Landslide] version[2.0.0], pid[11109], build[de54438/2015-10-22T08:09:48Z][2016-03-01 10:32:02,959][INFO ][node                     ] [Landslide] initializing ...Exception in thread "main" java.lang.IllegalStateException: Unable to initialize pluginsLikely root cause: java.nio.file.FileSystemException: /home/elasticsearch/es/elasticsearch-2.0.0/plugins/ik.zip/plugin-descriptor.properties: Not a directory        at sun.nio.fs.UnixException.translateToIOException(UnixException.java:91)        at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:102)        at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:107)        at sun.nio.fs.UnixFileSystemProvider.newByteChannel(UnixFileSystemProvider.java:214)        at java.nio.file.Files.newByteChannel(Files.java:317)        at java.nio.file.Files.newByteChannel(Files.java:363)        at java.nio.file.spi.FileSystemProvider.newInputStream(FileSystemProvider.java:380)        at java.nio.file.Files.newInputStream(Files.java:108)        at org.elasticsearch.plugins.PluginInfo.readFromProperties(PluginInfo.java:86)        at org.elasticsearch.plugins.PluginsService.getPluginBundles(PluginsService.java:306)        at org.elasticsearch.plugins.PluginsService.(PluginsService.java:112)        at org.elasticsearch.node.Node.(Node.java:144)        at org.elasticsearch.node.NodeBuilder.build(NodeBuilder.java:145)        at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:170)        at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:270)        at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:35)

我们从启动就看的出来,IK分词器安装成功。
