篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ELK学习笔记---安装ELK 5.x版相关的知识,希望对你有一定的参考价值。
ELK日志平台是一个完整的日志分析系统,有三个开源工具构建组成,分别是:Elasticsearch、Logstash和Kibana。Elasticsearch用于数据分析和深度搜索;Logstash作用是从其他服务器上传输和转发日志,对其集中管理,进行分析;Kibana则是提供了强大的UI展示,将数据可视化。
安装ELK日志平台
ELK基础环境需要java环境,官网要求5.x版本要大于java8。而且安装方式多样化,支持zip、tar.gz、rpm包、deb包、window环境还有docker环境。根据自己喜好选择吧。
我选择的是yum安装,简单方便,系统要求的话没有辣么严格,官网说yum安装方式不再支持centos5.x系列了,非要用centos5.x就去使用tar.gz包吧,官网有具体方法,不再复述。yum安装方式centos6.x和centos7.x都可以,但是我推荐用centos7.x安装,不知道为啥,感觉centos7.x支持更好,centos6.x装完经常会出问题。
还有一点需要说下就是,ELK各个组件版本要一致,官网要求的!
在一个就是安装顺序,为的是确保每个组件相互调用时都能正常运行:
1、Elasticsearch
X-Pack for Elasticsearch
Kibana
X-Pack for Kibana
LogstashBeatsElasticsearch Hadoop
安装Elasticsearch
1、导入Elasticsearch安装包PGP Key
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch
2、创建yum源
[[email protected] ~]# cat >> /etc/yum.repos.d/elasticsearch.repo <<EOF > [elasticsearch-5.x] > name=Elasticsearch repository for 5.x packages > baseurl=https://artifacts.elastic.co/packages/5.x/yum > gpgcheck=1 > gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch > enabled=1 > autorefresh=1 > type=rpm-md > EOF
3、安装、启动Elasticsearch进程并开机启动
[[email protected] ~]$ sudo yum install elasticsearch [[email protected] ~]$ sudo /bin/systemctl daemon-reload [[email protected] ~]$ sudo /bin/systemctl enable elasticsearch.service [[email protected] ~]$ sudo systemctl start elasticsearch.service
4、检查Elasticsearch是否已经启动
查看9200、9300是否已经启动
[[email protected] ~]$ curl http://localhost:9200 { "name" : "F5Mw8Pp", "cluster_name" : "elasticsearch", "cluster_uuid" : "zVEeXtPNTaeH-TKah7Buzw", "version" : { "number" : "5.4.0", "build_hash" : "780f8c4", "build_date" : "2017-04-28T17:43:27.229Z", "build_snapshot" : false, "lucene_version" : "6.5.0" }, "tagline" : "You Know, for Search" }
5、配置Elasticsearch
rpm包配置文件在/etc/elasticsearch下面的elasticsearch.yml
vim /etc/elasticsearch/elasticsearch.yml cluster.name: elasticsearch-test node.name: node-1 path.data: /var/lib/elasticsearch path.logs: /var/log/elasticsearch network.host: 0.0.0.0 [[email protected] ~]$ sudo systemctl restart elasticsearch.service [[email protected] ~]$ curl http://localhost:9200 { "name" : "node-1", "cluster_name" : "elasticsearch-test", "cluster_uuid" : "zVEeXtPNTaeH-TKah7Buzw", "version" : { "number" : "5.4.0", "build_hash" : "780f8c4", "build_date" : "2017-04-28T17:43:27.229Z", "build_snapshot" : false, "lucene_version" : "6.5.0" }, "tagline" : "You Know, for Search" }
6、将/etc/elasticsearch/配置拷贝到/usr/share/elasticsearch/config下面
[[email protected] ~]$ sudo mkdir /usr/local/elasticsearch/config [[email protected] ~]$ sudo ln -sf /etc/elasticsearch/* /usr/local/elasticsearch/config/ [[email protected] ~]$ sudo chown -R elasticsearch:elasticsearch /usr/local/elasticsearch [[email protected] ~]$ sudo systemctl restart elasticsearch.service
注意:这一点好多人不会注意,因为你不修复也不会启动失败,但是就是写不进数据进去,这个坑好久才发现,看下日志会报错,但是却能启动,我也是服了!~
7、装个head插件
这个插件5.X官网不再支持了,插件命令没有了,因为它有自己x-pack插件了,但是我装了x-pack发现着实让人吐血,有安全认证方面的问题,导致elk各种问题出现,目前还没研究明白,时间不充裕。
这个head插件我是直接抄的网上大神制作,略有改动。
7.1、下载并配置nodejs
由于head插件本质上还是一个nodejs的工程,因此需要安装node,使用npm来安装依赖的包。(npm可以理解为maven)
去官网下载nodejs,https://nodejs.org/en/download/
wget https://nodejs.org/dist/v8.1.1/node-v8.1.1-linux-x64.tar.xz tar xf node-v8.1.1-linux-x64.tar.xz mv node-v8.1.1-linux-x64 /usr/local/node chown -R elasticsearch:elasticsearch node/ ln -sf /usr/local/node/bin/node /usr/bin/node ln -sf /usr/local/node/bin/npm /usr/bin/npm
7.2、安装grunt
npm install -g grunt-cli ln -sf /usr/local/node/bin/grunt /usr/bin/grunt cd /var/lib/elasticsearch
7.3、下载、安装并配置head
yum -y install git cd /var/lib/elasticsearch git clone git://github.com/mobz/elasticsearch-head.git chown -R elasticsearch:elasticsearch elasticsearch-head/ cd elasticsearch-head/ npm install
7.4、配置head文件
[[email protected] ~]# cd /var/lib/elasticsearch/elasticsearch-head/ vim Gruntfile.js connect: { server: { options: { port: 9100, hostname: "0.0.0.0", base: ‘.‘, keepalive: true } } } [[email protected] elasticsearch-head]# cd _site/ [[email protected] _site]# vim app.js
把localhost修改成你es的服务器地址:
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://10.10.10.10:9200";
7.5、启动head插件
grunt server &
安装Kibana
1、yum安装Kibana
[[email protected] ~]$ sudo yum install kibana
rpm包配置文件在/etc/kibana下面的kibana.yml
/etc/kibana/kibana.yml
2、配置Kibana文件
[[email protected] ~]$ vim /etc/kibana/kibana.yml server.port: 5601 server.host: "0.0.0.0" elasticsearch.url: "http://localhost:9200"
3、启动并设置开机启动
[[email protected] ~]$ sudo systemctl enable kibana.service Created symlink from /etc/systemd/system/multi-user.target.wants/kibana.service to /etc/systemd/system/kibana.service [[email protected] ~]$ sudo systemctl start kibana.service
安装Logstash
1、yum安装Logstash
[[email protected] ~]$ sudo yum -y install logstash [[email protected] ~]$ sudo systemctl start logstash.service [[email protected] ~]$ sudo ln -s /usr/share/logstash/bin/logstash /usr/bin/logstash [[email protected] ~]$ sudo -u logstash sh -c ‘mkdir -pv /usr/share/logstash/config‘ [[email protected] ~]$ sudo -u logstash sh -c ‘ln -s /etc/logstash/* /usr/share/logstash/config/‘
2、测试Logstash是否能正常运行
[[email protected] ~]$ sudo logstash -e ‘input {stdin{}}output { stdout{}}‘ hello world 2017-06-02T07:14:13.130Z localhost hello world [[email protected] ~]$ sudo logstash -e ‘input {stdin{}}output { stdout{codec=>rubydebug}}‘ hello world The stdin plugin is now waiting for input: { "@timestamp" => 2017-06-02T07:17:44.053Z, "@version" => "1", "host" => "localhost", "message" => "hello world" }
3、写个测试文件,测试一下es是否能够接受数据
[[email protected] ~]$ vim /etc/logstash/conf.d/test.conf input{ stdin{} } output{ elaticsearch{ hosts => "127.0.0.1:9200" index => "test-messages-%{+YYYY.MM.dd}" } } [[email protected] ~]$ logstash -f /etc/logstash/conf.d/test.conf -t Sending Logstash‘s logs to /var/log/logstash which is now configured via log4j2.properties Configuration OK
[[email protected] ~]$ logstash -f /etc/logstash/conf.d/test.conf Sending Logstash‘s logs to /var/log/logstash which is now configured via log4j2.properties The stdin plugin is now waiting for input: hello world this is test message study logstash 这是es显示的索引内容了
4、Kibana里添加该索引(测试),只要es里面能产生索引,Kibana就能加在上去
