关于ES这里先不多介绍了，先看下怎么安装ES吧。

 

这里安装的ES是基于JDK 1.8，需要先安装JDK1.8，否则会提示requirement is not satisfied。

安装JDK 1.8

1. 下载JDK1.8

可以到Java Downloads | Oracle下载，但是Oracle需要登录或者注册，然后才能下载，注册一个就好了。

2. 在Mac上下载后可以直接点击安装，然后一路向下，安装完成。

3. 查看下当前JAVA HOME对应的Java版本

(base) ➜  ~ /usr/libexec/java_home -v
java_home: option requires an argument -- v
/Library/Java/JavaVirtualMachines/jdk-13.0.1.jdk/Contents/Home

发现我这里的JAVA HOME是jdk-13.0.1.jdk，这个不是我们刚才安装的。可以看一下我们安装的所有版本：

(base) ➜  ~ ls /Library/Java/JavaVirtualMachines/
jdk-13.0.1.jdk   jdk1.8.0_241.jdk

我们已经安装了jdk1.8.0_241.jdk，我们要做的是修改JAVA_HOME的路径

4. 修改JAVA HOME

打开~/.bash_profile，然后添加export修改环境变量。

(base) ➜  ~ vim ~/.bash_profile

然后添加如下命令

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home

下次打开bash的时候会自动加载~/.bash_profile，为了不关闭命令行窗口，我们之间让配置生效即可。

(base) ➜  ~ source ~/.bash_profile

5. 查看当前的JAVA HOME和Java 版本

(base) ➜  ~ java -version
java version "1.8.0_241"
Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot(TM) 64-Bit Server VM (build 25.241-b07, mixed mode)
(base) ➜  ~ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home

安装ES

1. Mac上安装ES方法比较简单，直接用brew安装即可。

brew install elasticsearch

2. 安装完后可以查看ES的版本

(base) ➜  search elasticsearch -version
Java HotSpot(TM) 64-Bit Server VM warning: Cannot open file logs/gc.log due to No such file or directory

Version: 6.8.7, Build: oss/tar/c63e621/2020-02-26T14:38:01.193138Z, JVM: 1.8.0_241

3. 启动ES，默认使用的9300端口号，我这里端口号被转成了9200

4. 可以在浏览器里看到本地启动的ES的信息

Kibana安装

可以直接用kibana连接ES，kibana是一种数据看板，可以不同的数据库，方便数据展示及索引。

1. 安装kibana

(base) ➜  search brew install kibana

2. 启动kibana，kibana会自动连接ES，当没有启动ES的时候，会提示warning，我们在另外一个窗口启动ES后，会自动连接上。
