在CentOS上装 ElasticSearch
参考官方文档:Install Elasticsearch with RPM
ElasticSearch依赖Java,所以需要先安装Java:
到Oracle官网找到下载链接
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
wget http://download.oracle.com/otn-pub/java/jdk/8u112-b15/jdk-8u112-linux-x64.rpm?AuthParam=1480402865_ac614d1fc3f20dfc6e7d8a525f7f4190
下载完成后:
rpm -ivh jdk-8u112-linux-x64.rpm\?AuthParam\=1480402865_ac614d1fc3f20dfc6e7d8a525f7f4190
开始安装ES,先下载公钥:
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
添加源:
cd yum.repos.d/
vi elasticsearch.repo
编辑elasticsearch.repo:
[elasticsearch-5.x] name=Elasticsearch repository for 5.x packages baseurl=https://artifacts.elastic.co/packages/5.x/yum gpgcheck=1 gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch enabled=1 autorefresh=1 type=rpm-md
安装:
yum install elasticsearch
也可以手动下载安装:
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.0.2.rpm sha1sum elasticsearch-5.0.2.rpm sudo rpm --install elasticsearch-5.0.2.rpm
不过这里会报错,官网坑我,直接用浏览器打开地址:
后来改上面的安装方法发现官网提供是是5.0.1的包,所以把这里的5.0.2改成5.0.1即可。
安装完后启动服务:
systemctl start elasticsearch.service
查看运行状态:
curl http://localhost:9200
安装成功。接下来要开放端口:
firewall-cmd --zone=public --add-port=9200/tcp --permanent firewall-cmd --reload
可以开始测试了,如果需要在Windows上测试,还需要改下配置,ES默认绑定了本地地址
cd /etc/elasticsearch/
vi elasticsearch.yml
修改network.host节点:
network.host: 192.168.1.10
这里可以使用IP,也可以使用:
_[networkInterface]_
Addresses of a network interface, for example _en0_
.
_local_
Any loopback addresses on the system, for example 127.0.0.1
.
_site_
Any site-local addresses on the system, for example 192.168.0.1
.
_global_
Any globally-scoped addresses on the system, for example 8.8.8.8
.
这里我使用网卡,使用ip addr 可以查看:
这里使用无线网卡:wlp3s0
也就是:
network.host: _wlp3s0_
保存后重启,在Windows打开http://10.255.20.44:9200/即可访问:
