ELK实时日志分析平台(elk+kafka+metricbeat)-elasticsearch部署(五)

192.168.30.121,192.168.30.122,192.168.30.123上配置elasticsearch集群：
在所有主机上添加elk用户

在所有主机上解压elasticsearch，并更改属主，组：







修改192.168.30.121配置文件：
#cat>elasticsearch/config/elasticsearch.yml<<EOF
cluster.name: my-es
node.name: node-1
path.data: /usr/local/elk/elasticsearch/data
path.logs: /usr/local/elk/elasticsearch/logs
bootstrap.memory_lock: false
network.host: 192.168.30.121
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.30.121", "192.168.30.122","192.168.30.123"]
discovery.zen.minimum_master_nodes: 2
node.master: true
node.data: true
EOF










修改192.168.30.122配置：
#cat>elasticsearch/config/elasticsearch.yml<<EOF
cluster.name: my-es
node.name: node-2
path.data: /usr/local/elk/elasticsearch/data
path.logs: /usr/local/elk/elasticsearch/logs
bootstrap.memory_lock: false
network.host: 192.168.30.122
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.30.121", "192.168.30.122","192.168.30.123"]
discovery.zen.minimum_master_nodes: 2
node.master: true
node.data: true
EOF










修改192.168.30.123配置：
#cat>elasticsearch/config/elasticsearch.yml<<EOF
cluster.name: my-es
node.name: node-3
path.data: /usr/local/elk/elasticsearch/data
path.logs: /usr/local/elk/elasticsearch/logs
bootstrap.memory_lock: false
network.host: 192.168.30.123
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.30.121", "192.168.30.122","192.168.30.123"]
discovery.zen.minimum_master_nodes: 2
node.master: true
node.data: true
EOF



启动：
cd /usr/local/elk/elasticsearch/logs && nohup sudo -u elk /usr/local/elk/elasticsearch/bin/elasticsearch &
检查：




安装head：
检查依赖包：



安装:



#git clone https://github.com/mobz/elasticsearch-head.git cd elasticsearch-head/
npm config set registry https://registry.npm.taobao.org npm install #安装较慢，失败可多次执行

修改vim Gruntfile.js
connect: {
server: {
options: {
hostname: "192.168.30.121",
port: 9100,
base: '.',
keepalive: true
}
}
}

});

修改app.js：
[root@k8s-etcd1elasticsearch-head]# vim _site/app.js
this.base_uri =this.config.base_uri || this.prefs.get("app-base_uri") ||"http://192.168.30.121:9200";

在所有elasticsearch的配置文件追添以下两行，然后重启elasticsearch：
http.cors.enabled: true
http.cors.allow-origin: "*"

启动head：
[root@k8s-etcd1 elk]# cdelasticsearch-head/ && nohup grunt server -d &
