ELK集群日志中心集群、kafka、logstash

ES：用来日志存储

Logstash:用来日志的搜集，进行日志格式转换并且传送给别人（转发）

Kibana:主要用于日志的展示和分析

kafka

Filebeat:搜集文件数据

es-1

本地解析

vi /etc/hosts

scp /etc/hosts es-2:/etc/hosts

scp /etc/hosts es-3:/etc/hosts

yum -y install wget

安装配置jdk

wget 8u191

scp -3

tar xf jdk-8u191-linux-x64.tar.gz -C /usr/local/

[root@es-1 ~]# vim /etc/profile
JAVA_HOME=/usr/local/java
PATH=$JAVA_HOME/bin:$PATH
export JAVA_HOME PATH
[root@es-1~]# source /etc/profile

安装配置ES

useradd elsearch

ssh es-2 useradd elsearch

ssh es-3 useradd elsearch

echo "123456" | passwd --stdin "elsearch"

wget els包

vim /usr/local/elasticsearch/config/elasticsearch.yml

创建ES数据及日志存储目录

mkdir -p /data/elasticsearch/{logs,data}

scp /usr/local/elasticsearch/config/elasticsearch.yml es-3:/usr/local/elasticsearch/config/elasticsearch.yml

系统优化

vi /etc/security/limits.conf

echo "vm.max_map_count=262144" >> /etc/sysctl.conf

sysctl -p

su - elsearch -c "cd /usr/local/elasticsearch && nohup bin/elasticsearch &"

es-2

echo "123456" | passwd --stdin "elsearch"

mkdir -p /data/elasticsearch/{logs,data}

echo "vm.max_map_count=262144" >> /etc/sysctl.conf

sysctl -p

ss -antpl //看9200

es-3

echo "123456" | passwd --stdin "elsearch"

mkdir -p /data/elasticsearch/{logs,data}

vim /usr/local/elasticsearch-6.5.4/config/elasticsearch.yml (改名字)

echo "vm.max_map_count=262144" >> /etc/sysctl.conf

sysctl -p

su - elsearch -c "cd /usr/local/elasticsearch && nohup bin/elasticsearch &"

ss -antpl //看9200

kibana

本地解析

vi /etc/hosts

IP es-1、2、3

上传kibana包

vi /usr/local/kibana/config/kibana.yml
