一、安装Elasticsearch集群web管理工具Cerebro
1.1 下载
https://github.com/lmenezes/cerebro/releases
[root@es-master1 software]# wget https://github.com/lmenezes/cerebro/releases/download/v0.8.1/cerebro-0.8.1.zip
1.2 安装及配置
[root@es-master1 software]# unzip cerebro-0.8.1.zip
[root@es-master1 software]# ln -s cerebro-0.8.1 cerebro
[root@es-master1 software]# cd cerebro
[root@es-master1 cerebro]# ll
total 16
drwxr-xr-x 2 root root 40 Dec 5 10:40 bin
drwxr-xr-x 3 root root 103 Dec 5 10:40 conf
drwxr-xr-x 2 root root 8192 Dec 5 10:40 lib
-rw-r--r-- 1 root root 1081 Jun 20 11:03 README.md
[root@es-master1 cerebro]# cd conf
[root@es-master1 conf]# vim application.conf
hosts = [
{
host = "http://es-master1.linuxplus.com:9200"
name = "linuxplus"
auth = {
username = "root"
password = "123456"
}
}
]
[root@es-master1 conf]# cd ..
[root@es-master1 cerebro]# nohup ./bin/cerebro -Dhttp.port=1234 -Dhttp.address=IP &
[1] 77172
二、配置Elasticsearch实现冷热数据分离
| 节点名称 | 服务器类型 | 存储数据 |
| es-master1 | SATA | 元数据 |
| es-master2 | ||
| es-master3 | ||
| es-hot1 | SSD | Hot |
| es-hot2 | ||
| es-hot3 | ||
| es-stale1 | SATA | Cold |
| es-stale2 |
2.1 配置Master节点
Master1节点配置（其他节点配置类似）
[root@es-master1 ~]# cd /etc/elasticsearch/ [root@es-master1 elasticsearch]# vim elasticsearch.yml cluster.name: linuxplus node.name: es-master1.linuxplus.com node.attr.rack: r6 node.master: true node.data: false path.data: /var/lib/elasticsearch path.logs: /var/log/elasticsearch network.host: 0.0.0.0 discovery.zen.ping.unicast.hosts: ["es-master1.linuxplus.com:9300","es-master2.linuxplus.com:9300","es-master3.linuxplus.com:9300","es-hot1.linuxplus.com:9300","es-hot2.linuxplus.com:9300","es-hot3.linuxplus.com:9300","es-stale1.linuxplus.com:9300","es-stale2.linuxplus.com:9300"] discovery.zen.minimum_master_nodes: 1 bootstrap.system_call_filter: false
2.2 配置Hot节点
Hot1节点配置（其他节点配置类似）
[root@es-hot1 elasticsearch]# vim elasticsearch.yml cluster.name: linuxplus node.name: es-hot1.linuxplus.com #需要修改 node.attr.rack: r1 node.master: false node.data: true path.data: /var/lib/elasticsearch path.logs: /var/log/elasticsearch network.host: 10.10.10.24 #需要修改 discovery.zen.ping.unicast.hosts: ["es-master1.linuxplus.com:9300","es-master2.linuxplus.com:9300","es-master3.linuxplus.com:9300"] discovery.zen.minimum_master_nodes: 1 bootstrap.system_call_filter: false node.attr.box_type: hot [root@es-hot1 elasticsearch]# /etc/init.d/elasticsearch start
在Hot节点打tag
node.attr.box_type: hot
2.3 配置Stale节点
Stale1节点配置（其他节点配置类似）
[root@es-stale1 elasticsearch]# vim elasticsearch.yml cluster.name: linuxplus node.name: es-stale1.linuxplus.com node.attr.rack: r1 node.master: false node.data: true path.data: /var/lib/elasticsearch path.logs: /var/log/elasticsearch network.host: 10.10.10.27 discovery.zen.ping.unicast.hosts: ["es-master1.linuxplus.com:9300","es-master2.linuxplus.com:9300","es-master3.linuxplus.com:9300"] discovery.zen.minimum_master_nodes: 1 bootstrap.system_call_filter: false node.attr.box_type: cold [root@es-stale1 elasticsearch]# /etc/init.d/elasticsearch start
在Stale节点打tag
node.attr.box_type: cold
三、实现热数据写入指定节点
通过Cerebro修改模板添加如下配置
"settings": {
"index": {
"number_of_shards": "5",
"auto_expand_replicas": "0-1",
"routing": {
"allocation": {
"require": {
"box_type": "hot"
}
}
}
}
},
通过shell脚本将Hot数据（保留7天）迁移到Stale
#!/bin/bash
Time=$(date -d "1 week ago" +"%Y.%m.%d")
Hostname=$(hostname)
arr=("cron" "messages" "secure" "tomcat" "nginx-access" "nginxtcp" "nginxerror" "windows" ".monitoring-es-6" ".monitoring-beats-6" ".monitoring-kibana-6" ".monitoring-logstash-6" "metricbeat-6.5.3")
for var in ${arr[@]}
do
curl -H "Content-Type: application/json" -XPUT http://$Hostname:9200/$var-$Time/_settings?pretty -d'
{
"settings": {
"index.routing.allocation.require.box_type": "cold"
}
}'
done
