elasticsearch centos集群
前提请搭建好jdk
准备三个节点
192.168.1.99 192.168.1.100 192.168.1.102
下载
cd /mnt/soft/
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.2.tar.gz
tar -zxvf elasticsearch-5.5.2.tar.gz
每个节点执行
创建 elastic 用户
useradd -m elastic
创建数据目录
rm -rf /var/lib/elasticsearch
mkdir /var/lib/elasticsearch
chown elastic.elastic /var/lib/elasticsearch
创建日志目录
mkdir -p /var/log/elasticsearch
chown elastic.elastic /var/log/elasticsearch
增加 vi /etc/sysctl.conf 配置，执行 sysctl -p 生效
vm.max_map_count = 262144
增加 vi /etc/security/limits.conf 配置
elastic soft nofile 65536
elastic hard nofile 65536
elastic soft memlock unlimited
elastic hard memlock unlimited
每个node 机器hosts命名 /etc/hosts
es1 192.168.1.99
es2 192.168.1.100
es3 192.168.1.102
es1
vim /mnt/soft/elastic-node1/config/elasitcsearch.yml 文件修改

## 如下配置是为了解决 Elasticsearch可视化工具 dejavu的跨域问题！若不用可视化工具则可省略之
