elk群集收集HTTP日志部署

主机名	软件包
node-1 192.168.100.11	elasticsearch-2.3.3.tar.gz jdk-8u181-linux-x64.tar.gz kibana-4.5.1-linux-x64.tar.gz logstash-2.3.3.tar.gz
node-2 192.168.100.12	elasticsearch-2.3.3.tar.gz jdk-8u181-linux-x64.tar.gz
syslog-client 192.168.100.13	logstash-2.3.3.tar.gz jdk-8u181-linux-x64.tar.gz

设置主机名和hosts文件

[root@localhost ~]# vim /etc/hosts   ##三台机器同步设置
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.11 node-1
192.168.100.12 node-2
192.168.100.13 syslog-client

[root@localhost ~]# hostnamectl set-hostname node-1
[root@localhost ~]# hostnamectl set-hostname node-2
[root@localhost ~]# hostnamectl set-hostname syslog-client

设置Java环境三台一样步骤

[root@localhost ~]# vim /etc/profile
export JAVA_HOME=/usr/local/java
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar
[root@localhost ~]# source /etc/profile
[root@node-1 ~]# tar zxvf jdk-8u181-linux-x64.tar.gz
[root@localhost ~]# mv jdk1.8.0_181/ /usr/local/java

安装elasticsearch（node-1和node-2一样步骤，node-2就不写了）

[root@node-1 ~]# tar zxvf elasticsearch-2.3.3.tar.gz -C /usr/local/
[root@node-1 ~]# useradd user1
[root@node-1 ~]# passwd user1
更改用户 user1 的密码 。
新的 密码：
无效的密码： 密码少于 8 个字符
重新输入新的 密码：
passwd：所有的身份验证令牌已经成功更新。
[root@node-1 elasticsearch-2.3.3]# chown -R user1:user1 /usr/local/elasticsearch-2.3.3
[root@node-1 ~]# vim /usr/local/elasticsearch-2.3.3/config/elasticsearch.yml
 cluster.name: my-application   #取消注释
 node.name: node-1              #取消注释node-2的修改为node-2
 path.data: /usr/local/elasticsearch-2.3.3/data     #取消注释修改路径
 path.logs: /usr/local/elasticsearch-2.3.3/logs     #取消注释修改路径
 bootstrap.mlockall: true         #取消注释              
 network.host: 192.168.100.11     #取消注释修改为本机ip
 http.port: 9200
 discovery.zen.ping.unicast.hosts: ["192.168.100.11", "192.168.100.12"] #取消注释改为node1和2的IP
 discovery.zen.minimum_master_nodes: 1    #取消注释 改为1
[root@node-1 elasticsearch-2.3.3]# su - user1
[user1@node-1 ~]$ /usr/local/elasticsearch-2.3.3/bin/elasticsearch


node-2配置步骤相同  注意把IP改为本机的就OK

打开浏览器访问本机IP的9200端口查看elasticsearch

安装logstash（syslog-client）

[root@syslog-client ~]# tar zxvf logstash-2.3.3
[root@syslog-client ~]# cd logstash-2.3.3/bin/
[root@syslog-client bin]# vim log_system.conf
input {
        file {
          path=>"/var/log/messages"
          type=>"system"
          start_position=>"beginning"
             }
      }

output {
        elasticsearch {
          hosts=>["192.168.100.11:9200"]
          index=>"system-%{+YYYY.MM.dd}"
             }
       }
[root@syslog-client bin]# ./logstash -f log_system.conf 
Settings: Default pipeline workers: 1
Pipeline main started

安装kibana-4.5.1（node-1）

[root@node-1 ~]# tar zxvf kibana-4.5.1-linux-x64.tar.gz -C /usr/local/
[root@node-1 ~]# vim /usr/local/kibana-4.5.1-linux-x64/config/kibana.yml 
 elasticsearch.url: "http://192.168.100.11:9200"   #改为本机elasticsearch的IP
 kibana.index: ".kibana"   #取消注释
