Centos 7 安装 ELK 5.6.8 及基础的配置

下载

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.8.rpm

wget https://artifacts.elastic.co/downloads/logstash/logstash-5.6.8.rpm

wget https://artifacts.elastic.co/downloads/kibana/kibana-5.6.8-x86_64.rpm

wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-5.6.8-x86_64.rpm

安装

yum install ./*.rpm

再安装一个redis作为filebeat与logstash间的缓冲，这里是从epel直接yum安装的，版本是：3.2.10

yum install redis

另外还需要安装好jdk8，这里的路径是：/mydata/jdk1.8.0_111

基础配置

（下文中蓝色文字为修改的内容，绿色为注释，其他是命令）

redis

mkdir -p /mydata/redis
chown -R redis:redis /mydata/redis
vim /etc/redis.conf
    bind 0.0.0.0
    dir /mydata/redis
systemctl start redis
systemctl enable redis

filebeat

vim /etc/filebeat/filebeat.yml
    先把该文件中预设的配置全部注释掉，然后加上下面的
    filebeat.prospectors:
    - input_type: log
      paths:
        - /root/test.log　　从一个测试文件中获取数据
    output.redis:　　输出到redis队列
        enabled: true
        hosts: ["127.0.0.1:6379"]
        db: 1
        key: "elk_test_list"
systemctl start filebeat
systemctl enable filebeat

logstash

logstash在安装了rpm包后，还需再安装一下：

vim /etc/logstash/startup.options
    JAVACMD=${JAVA_HOME}/bin/java
cd /usr/share/logstash/bin
./system-install

然后再进行基础配置：

mkdir -p /mydata/logstash
chown -R logstash:logstash /mydata/logstash
vim /etc/logstash/logstash.yml
    path.data: /mydata/logstash
cd /etc/logstash/conf.d
vim test.conf
    input {
        redis {　　从redis队列读数据，要与上面filebeat的配置一致
            host => "127.0.0.1"
            port => 6379
            db => 1
            data_type => "list"
            key => "elk_test_list"
            threads => 3
        }
    }
    filter {　　解析内容，这里用一个IP和一个字符串作测试
        grok {
            match => { "message" => '^%{IP:myip} %{DATA:myname}$' }
        }
    }
    output {
        elasticsearch {　　输出到elasticsearch
            hosts => ["127.0.0.1:9200"]
            index => "test-log-%{+YYYY.MM.dd}"
        }
    }
systemctl start logstash
systemctl enable logstash

elasticsearch

vim /etc/sysconfig/elasticsearch
    JAVA_HOME=/mydata/jdk1.8.0_111
vim /etc/elasticsearch/elasticsearch.yml
    path.data: /mydata/elasticsearch
    network.host: 0.0.0.0
mkdir -p /mydata/elasticsearch
chown -R elasticsearch:elasticsearch /mydata/elasticsearch
systemctl start elasticsearch
systemctl enable elasticsearch

kibana

vim /etc/kibana/kibana.yml
    server.host: "0.0.0.0"
systemctl start kibana
systemctl enable kibana

进行测试

touch /root/test.log
echo '127.0.0.1 张三' >> /root/test.log
echo '127.0.0.2 李四' >> /root/test.log
