关于ELK
准备工作 1.准备两台虚拟机(我的是centos7系统的)
一台是 192.168.18.140
一台是 192.168.18.141
2.关闭防火墙 和SELinux
systemctl stop firewalld setenforce 0
优化系统
vim /etc/security/limits.conf ******************************** * soft nproc 65535 * hard nproc 65535 * soft nofile 65535 * hard nofile 65535 ********************************
测试是否优化系统完成 断开连接重新连接一下如下所示 就可以了
[root@localhost ~]# ulimit -n 65535
这两台服务器都需要安装jdk环境
[root@localhost src]# rpm -ivh jdk-8u131-linux-x64_.rpm 准备中... ################################# [100%] 正在升级/安装... 1:jdk1.8.0_131-2000:1.8.0_131-fcs ################################# [100%] Unpacking JAR files... tools.jar... plugin.jar... javaws.jar... deploy.jar... rt.jar... jsse.jar... charsets.jar... localedata.jar... [root@localhost src]#
140 服务器是ES+kibana
先安装ES(elasticsearch)
[root@localhost src]# rpm -ivh elasticsearch-6.6.2.rpm 警告:elasticsearch-6.6.2.rpm: 头V4 RSA/SHA512 Signature, 密钥 ID d88e42b4: NOKEY 准备中... ################################# [100%] Creating elasticsearch group... OK Creating elasticsearch user... OK 正在升级/安装... 1:elasticsearch-0:6.6.2-1 ################################# [100%] ### NOT starting on installation, please execute the following statements to configure elasticsearch service to start automatically using systemd sudo systemctl daemon-reload sudo systemctl enable elasticsearch.service ### You can start elasticsearch service by executing sudo systemctl start elasticsearch.service Created elasticsearch keystore in /etc/elasticsearch
编辑elasticesarch的配置文件
vim /etc/elasticsearch/elasticsearch.yml 修改以下内容 network.host: 192.168.18.140 //修改为本机IP地址 http.port: 9200
systemctl restart elasticsearch
开始安装kibana
rpm -ivh kibana-6.6.2-x86_64.rpm 警告:kibana-6.6.2-x86_64.rpm: 头V4 RSA/SHA512 Signature, 密钥 ID d88e42b4: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:kibana-6.6.2-1 ################################# [100%]
编辑kibana的配置文件
修改成如下所示就可以了 cat /etc/kibana/kibana.yml |grep -v '^#' ***************************************** server.port: 5601 server.host: "0.0.0.0" elasticsearch.hosts: ["http://192.168.18.140:9200"] *****************************************
重启kibana
sysetmct restart kibana
给予权限
chmod -R 777 /var/log/messages
141 服务器是logstash
安装
rpm -ivh logstash-6.6.0.rpm 警告:logstash-6.6.0.rpm: 头V4 RSA/SHA512 Signature, 密钥 ID d88e42b4: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:logstash-1:6.6.0-1 ################################# [100%] Using provided startup.options file: /etc/logstash/startup.options Successfully created system startup script for Logstash
编写一个收集日志的配置文件
vim /etc/logstash/conf.d/system.conf
*******************************************
input {
file {
path => "/var/log/messages"
type => "system-log"
start_position => "beginning"
}
}
output {
elasticsearch {
hosts => "192.168.18.140:9200"
index => "system_log-%{+YYYY.MM.dd}"
}
}
*******************************************
重启服务
systemctl restart logstash
给予权限
chmod -R 777 /var/log/messages
执行 这条命令 curl -X GET HTTP://192.168.18.140:9200/_cat/indices?v 如下所示表示成功可以检索 在两台服务器上都执行以下这条命令
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size green open .kibana_1 JK3lTv0uSw2ewk3_Qvwmww 1 0 2 0 8.6kb 8.6kb yellow open system_log-2019.12.08 12ezV-ilT9uIU7if-xIATw 5 1 328 0 189.2kb 189.2kb
访问kibana的服务器 在浏览器中
