1.下载安装文件
假如我们下载到/opt/elk目录
wget https:
//download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.3.3/elasticsearch-2.3.3.tar.gz
|
2.解压安装文件
假如我们解压到/opt/elk目录
tar zxvf elasticsearch-
2.3
.
3
.tar.gz
|
3.修改elasticsearch.yml
打开/opt/elk/elasticsearch-2.3.3/config/elasticsearch.yml，修改配置内容如下：
cluster.name: goeasy-dev
node.name: goeasy-dev-node1
network.host:
192.168
.
1.10
http.port:
9200
|
4.新建Linux用户
由于elasticsearch不能用root用户启动，因此我们需要新建一个用户来启动它
a. 使用useradd命令创建一个用户，并设置登录密码
useradd phy
passwd phy
输入新密码
|
b.给新建的用户分配目录权限
假如/opt/elk/elasticsearch-2.3.3是我们安装的目录，那需要把这个目录的权限分配给用户
chown -R phy:phy /opt/elk/elasticsearch-
2.3
.
3
|
5.启动ElasticSearch
a. 使用su命令从root用户切换到phy用户
su phy
输入密码
|
b. 打开/opt/elk/elasticsearch-2.3.3目录，然后运行：
bin/elasticsearch
#如果想在后台运行，可以增加-d
bin/elasticsearch -d
|
6.测试
在浏览器中输入http://192.168.1.10:9200/ ，如果能看到下面返回信息，说明elasticsearch安装成功了

:
"goeasy-dev-node1"
,
