---

二、正式安装ELK

1，安装jdk 1.8及以上的版本

创建一个目录 /usr/local/java
[root@master-node ~]#mkdir -pv /usr/local/java
上传文件
[root@master-node ~]# rz
[root@master-node ~]# ls
anaconda-ks.cfg  jdk-8u181-linux-x64.tar.gz
[root@master-node ~]# tar xf jdk-8u181-linux-x64.tar.gz  -C /usr/local/java
[root@master-node ~]# vim /etc/profile
最后添加如下：
JAVA_HOME=/usr/local/java/jdk1.8.0_181 
export PATH=$PATH:$JAVA_HOME/bin
[root@master-node ~]# source /etc/profile
[root@master-node bin]# ln -s /usr/local/java/jdk1.8.0_181/bin/java java
测试运行Java
[root@master-node ~]# java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

 

2，下载Elasticsearch最新版本

  下载软件或者是已经下载好了上传到服务器上，我是下载好了上传服务器

[root@master-node /]# mkdir elk &&cd /elk
[root@master-node elk]# rz
[root@master-node elk]# ls
elasticsearch-6.4.2.tar.gz        logstash-6.4.2.tar.gz
kibana-6.4.2-linux-x86_64.tar.gz

 

 

3，解压到指定目录并将其重命名

[root@master-node elk]# tar xf elasticsearch-6.4.2.tar.gz  -C /usr/local
[root@master-node local]# mv elasticsearch-6.4.2  elasticsearch

 

4，创建一个普通用户elk用来运行elasticsearch

[root@master-node /]#groupadd elk
[root@master-node /]#useradd -g elk elk -m
[root@master-node local]# chown -R elk.elk /usr/local/elasticsearch/
[root@master-node local]# ll /usr/local/elasticsearch/
total 436
drwxr-xr-x  3 elk elk   4096 Oct 11 22:21 bin
drwxr-xr-x  2 elk elk    148 Sep 26 21:38 config
drwxr-xr-x  3 elk elk   4096 Sep 26 21:38 lib
-rw-r--r--  1 elk elk  13675 Sep 26 21:30 LICENSE.txt
drwxr-xr-x  2 elk elk      6 Sep 26 21:38 logs
drwxr-xr-x 27 elk elk   4096 Sep 26 21:38 modules
-rw-r--r--  1 elk elk 401465 Sep 26 21:38 NOTICE.txt
drwxr-xr-x  2 elk elk      6 Sep 26 21:38 plugins
-rw-r--r--  1 elk elk   8511 Sep 26 21:30 README.textile

 

5,创建一个elasticsearch数据存储目录，并赋予elk用户拥有所属权限

[root@master-node ~]# mkdir -p /data/elasticsearch
[root@master-node ~]#chown -R elk.elk /data/elasticsearch

 

6，修改elasticsearch配置文件,记得先备份一下配置文件再修改

[root@master-node ~]#cd /usr/local/elasticsearch/config
[root@master-node config]# cp elasticsearch.yml elasticsearch.yml.bak
[root@master-node config]# vim elasticsearch.yml
cluster.name: ELK-Cluster
node.name: master-node
path.data: /data/elasticsearch
path.logs: /usr/local/elasticsearch/logs
network.host: 10.93.58.41
http.port: 9200

 

7,修改相关内核参数

[root@master-node config]# echo "vm.max_map_count=262144" >> /etc/sysctl.conf
[root@master-node ~]# sysctl -p 
[root@master-node ~]# vim /etc/security/limits.conf
* soft nproc 65536
* hard nproc 65536
* soft nofile 65536
* hard nofile 65536

 

8，切换用户elk来运行elasticsearch

[root@master-node config]# su - elk
[elk@master-node ~]$ cd /usr/local/elasticsearch/
[elk@master-node elasticsearch]$ ./bin/elasticsearch -d

 

9,检查elasticsearch状态，如下则表示正常运行

[elk@master-node elasticsearch]$  curl http://10.93.58.41:9200
{
  "name" : "master-node",
  "cluster_name" : "ELK-Cluster",
  "cluster_uuid" : "nOMA1m-TQr65tXWpi5H8Dw",
  "version" : {
    "number" : "6.4.2",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "04711c2",
    "build_date" : "2018-09-26T13:34:09.098244Z",
    "build_snapshot" : false,
    "lucene_version" : "7.4.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

 

三、安装Logstash

1，解压到/usr/local目录下,并重命名为logstash

[root@master-node ~]# tar xf logstash-6.4.2.tar.gz  -C /usr/local/
[root@master-node ~]# cd /usr/local/
[root@master-node local]# mv logstash-6.4.2 logstash

 

2，修改配置文件

[root@master-node local]# cd logstash/
[root@master-node logstash]# cd config/
[root@master-node config]#vim  logstash.conf
input {
    file {
        path => ["/var/log/messages"]
        type => "syslog"
    }
}

filter {
    grok {
        match => [ "message", "%{SYSLOGBASE} %{GREEDYDATA:conte
nt}" ]
    }
}

output {
    elasticsearch {
        hosts => ["10.93.58.41:9200"]
        index => "syslog-%{+YYY.MM.dd}"
    }
}

 

3，指定配置文件运行logstash

[root@master-node bin]# ./logstash -f /usr/local/logstash/config/logstash.conf &
[root@master-node bin]# netstat -lntup |grep 9600
tcp6       0      0 127.0.0.1:9600          :::*                    LISTEN      5129/java

 

四，安装Kibana

1，解压到/usr/local并重命名为kibana

[root@master-node ~]# tar xf kibana-6.4.2-linux-x86_64.tar.gz  -C /usr/local
[root@master-node ~]# cd /usr/local/
[root@master-node local]# mv kibana-6.4.2-linux-x86_64 kibana

 

2，修改配置文件

[root@master-node local]# cd kibana/config/
[root@master-node config]# cp kibana.yml kibana.yml.bak
[root@master-node config]# vim kibana.yml
server.port: 5601
server.host: 10.93.58.41
elasticsearch.url: "http://10.93.58.41:9200"
logging.dest: /var/log/kibana.log

 

3，给/var/log/kibana.log文件加权限

[root@master-node config]#  touch /var/log/kibana.log
[root@master-node config]# chmod 777 /var/log/kibana.log

 

4，进入安装目录下/bin启动kibana

[root@master-node kibana]# cd bin/
[root@master-node bin]# ./kibana &

 

五、浏览器上访问elasticsearch和kibana

http://10.93.58.41:9200/  和http://10.93.58.41:5601/app/kibana#/home?_g=()
