安装java
elasticsearch 需要java环境
elasticsearch-6.x 要求java版本1.8.0_131 or later
rpm -ivh http://192.168.19.111:8080/panjunbai/jdk-8u141-linux-x64.rpm
安装elasticsearch
可以使用yum源安装,也可以下载rpm包直接安装
cat /etc/yum.repos.d/elastic.repo
[elasticsearch-6.x]
name=Elasticsearch repository for 6.x packages
baseurl=https://artifacts.elastic.co/packages/6.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md
yum install -y elasticsearch
rpm -ivh http://192.168.19.111:8080/panjunbai/elasticsearch-6.2.4.rpm
配置elasticsearch通用配置
配置java运行内存大小,修改/etc/elasticsearch/jvm.options文件中-Xms -Xmx的值,为java虚拟机运行的内存最小和最大值,必须相同。其他使用默认值即可。
[[email protected] elasticsearch]# cat /etc/elasticsearch/jvm.options |grep "^-Xm"
-Xms6g
-Xmx6g
创建elasticsearch运行的日志路径和数据路径
[[email protected] elasticsearch]# mkdir /data/es-data
[[email protected] elasticsearch]# mkdir /data/es-log
[[email protected] elasticsearch]# chown -R elasticsearch.elasticsearch /data
192.168.19.93 elasticsearch 配置
[[email protected] elasticsearch]# cat elasticsearch.yml |grep -v "^#"
cluster.name: test-panjunbai
node.name: node-94
path.data: /data/es-data
path.logs: /data/es-log
network.host: 192.168.19.94
http.port: 9200

discovery.zen.minimum_master_nodes: 1
node.master: true
node.data: true
192.168.19.94 elasticsearch 配置
[[email protected] elasticsearch]# cat elasticsearch.yml
cluster.name: test-panjunbai
node.name: node-93

在192.168.19.93、192.168.19.94 启动elasticsearch
systemctl start elasticsearch
启动成功后访问结果
