ELK stack (Elasticsearch,logstash,Kibana)集群安装步骤备忘

1. yum update 系统1. yum update 系统

2. 安装 java, yum install java

3. 安装elasticsearch （官网，rpm方式） yum install elasticsearch  https://www.elastic.co/guide/en/elasticsearch/reference/5.6/rpm.html   设置启动服务  systemctl daemon-reload  systemctl enable elasticsearch.service  systemctl start elasticsearch.service

3.1 关闭swap: swapoff -a

3.2 修改/etc/fstab  注释掉这一行 /dev/mapper/centos-swap swap

3.3 修改 /etc/elasticsearch/elasticsearch.yml 中的 cluster.name: F5ELK-cluster ， node.name: ELKnode1，network.host: 0.0.0.0

4. 安装kibana (官网，rpm)  vi /etc/kibana/kibana.yml  port 5601 修改server.host监听地址为0.0.0.0   systemctl daemon-reload  systemctl enable kibana.service  systemctl start kibana.service

5. 关闭centos7 firewall systemctl stop firewalld.service #停止firewallsystemctl disable firewalld.service #禁止firewall开机启动
6.安装elasticsearch-head 辅助工具https://github.com/mobz/elasticsearch-head#running-with-built-in-server 5.0版本后的elasticsearch不支持plugin方式，只支持独立服务器安装yum install gityum install npm

6.1 可能需要执行，如果没有自动下载安装的话 npm install phantomjs-prebuilt@2.1.15 --ignore-script

6.2 npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules/chokidar/node_modules/fsevents):npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.2: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})npm WARN elasticsearch-head@0.0.0 license should be a valid SPDX license expression
出现以上错误使用 npm install --no-optional
如果还出现 npm WARN elasticsearch-head@0.0.0 license should be a valid SPDX license expression 错误 则修改目录下的package.json  将Apache改为Apache-2.0 。详细 见http://blog.csdn.net/qq_36357820/article/details/77539843  （但没有安装node，grunt）这些东西

6.3 访问http://192.168.214.130:9100/ 访问 elasticsearch-head, 出现界面中填入 http://192.168.214.130:9200/ 并点击connect，如果后侧出现无法连接提示，则

6.3.1 修改/etc/elasticsearch/elasticsearch.yml 最后增加
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

6.3.2 修改/root/elasticsearch-head/Gruntfile.js   : 增加 hostname

connect: {
    server: {
        options: {
            port: 9100,
            hostname: '*',
            base: '.',
            keepalive: true
        }
    }
}

7. 安装logstash,  yum install logstash, logstash没有以服务启动. 测试验证  ./logstash -e 'input {stdin{}} output{stdout{}}'

8. 第二台节点安装。方法同一，elasticsearch.yml里配置不同的节点名，并配置 discovery.zen.ping.unicast.hosts: ["192.168.214.130", "192.168.214.131"] 否则elasticsearch-head里会显示集群状态黄色9. head因为是以独立服务器安装，第二台节点无需安装
