Mac安装Elasticsearch时提示：No Java runtime present, requesting install.

没有安装java的童鞋可以先去安装一下，地址：https://www.java.com/zh_CN/

安装之后还是提示如下错误：

1 ➜  elasticsearch-2.4.3 bin/elasticsearch
2 No Java runtime present, requesting install.
3 ➜  elasticsearch-2.4.3 java -version
4 No Java runtime present, requesting install.

执行如下解决方案：

 1 #  首先 cd elasticsearch-2.4.3(此处是指进入你下载并解压后的elasticsearch文件)
 2 ➜  Downloads cd elasticsearch-2.4.3 
 3 ➜  elasticsearch-2.4.3 
 4 ➜  elasticsearch-2.4.3 vim .bash_profile
 5 # 在文件中添加如下两句：
 6 # export JAVA_HOME="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"
 7 # export PATH=${JAVA_HOME}/bin:$PATH
 8 ➜  elasticsearch-2.4.3 source .bash_profile
 9 ➜  elasticsearch-2.4.3 java -version       
10 java version "1.8.0_151"
11 Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
12 Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)

至此，该问题解决。

继续执行2步，即可验证Elasticsearch是否安装成功：

　　第1步：运行elasticsearch文件，如下：

 1 ➜  elasticsearch-2.4.3 bin/elasticsearch

　　第2步：打开浏览器访问:http://localhost:9200/，看到如下json结果集，表明安装成功：

{
  "name" : "Googam",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "lqQ7DANKR3C3skh1JKJBdA",
  "version" : {
    "number" : "2.4.3",
    "build_hash" : "d38a34e7b75af4e17ead16f156feffa432b22be3",
    "build_timestamp" : "2016-12-07T16:28:56Z",
    "build_snapshot" : false,
    "lucene_version" : "5.5.2"
  },
  "tagline" : "You Know, for Search"
}
