elk搭建

Posted 2020-09-07

elk系统全部采用5.0版本

1、elk是依赖于java环境，所以要先安装jdk，主意elk5.0版本所需要的jdk必须在1.8以上

2、安装elasticsearch

yum -y install elasticsearch-5.0.1.rpm

mkdir -pv /elk/{data,logs}        //创建es存储的数据和日志文件

chown -R elasticsearch.elasticsearch /elk/*        //修改属主属组

修改es配置文件：

vim /etc/elasticsearch/elasticsearch.yml

     1cluster.name: my-application

     2node.name: node-1

     3path.data: /elk/data

     4path.logs: /elk/logs

     5network.host: 0.0.0.0

     6http.port: 9200

修改文件限制

 vim /etc/security/limits.d/90-nproc.conf

* 改为2048即可

修改jvm参数

]# vim /etc/elasticsearch/jvm.options

-Xms512m

-Xmx512m

此参数根据实际内存调整

启动elasticsearch，查看9200，9300端口是否启用

3、安装kibana

[[email protected] ~]# yum -y install kibana-5.0.1-x86_64.rpm 

修改kibana配置文件

[[email protected] ~]# vim /etc/kibana/kibana.yml

     1server.port: 5601

     2server.host: "0.0.0.0"

     3elasticsearch.url: "http://localhost:9200"

     4kibana.index: ".kibana"

启动kibana，查看端口5601是否开启

4、安装logstash

[[email protected] ~]# yum -y install logstash-5.0.1.rpm

编辑第一个测试文档

[[email protected]~]# cat /etc/logstash/conf.d/test.conf

    input {

             stdin {}

    }

    output {

             stdout {

                       codec =>"rubydebug"

             }

    }

测试：

[[email protected] ~]# /usr/share/logstash/bin/logstash -t  -f /etc/logstash/conf.d/test.conf    

-t：标识测试配置文件但并不启动

-f：表示用哪一个测试文件

WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults

Could not find log4j2 configuration at path /usr/share/logstash/config/log4j2.properties. Using default config which logs to console

Configuration OK

14:08:51.310 [LogStash::Runner] INFO  logstash.runner - Using config.test_and_exit mode. Config Validation Result: OK. Exiting Logstash

出现警告信息：因为在/usr/share/logstash的目录下没有找到config文件

解决方法：创建一个软连接

[[email protected] ~]# ln -sv /etc/logstash /usr/share/logstash/config

修改配置文件：

[[email protected]~]# cat /etc/logstash/conf.d/test.conf

    input {

         redis {

               host =>"192.168.0.224"

               port => 6379

               key => "syslog"

               type =>"message1"

               data_type =>"list"

       }

 }

 output {

     stdout {

           codec =>"rubydebug"

     }

            elasticsearch  {

                   hosts =>["localhost:9200"]

      }

        }

4、编译安装redis

先安装gcc

[[email protected] ~]# yum -y install gcc

[[email protected] ~]# tar xf redis-3.0.7.tar.gz -C /app/tools/

[[email protected] ~]# cd /app/tools/redis-3.0.7/

[[email protected] ~]# make

启动redis-server

[[email protected] redis-3.0.7]# /app/tools/redis-3.0.7/src/redis-server &

查看6379端口是否打开

5、安装filebeat

[[email protected] ~]# yum -y install filebeat-5.0.1-x86_64.rpm

 [[email protected] ~]# vim /etc/filebeat/filebeat.yml

 paths:

    #- /var/log/*.log

    - /var/log/messages

output.redis:

        hosts: ["192.168.0.224"]        //redis的地址

        port: 6379                            //redis的端口

        key: "syslog"                        //redis的索引名

6、测试

[[email protected] ~]# service filebeat start

进入redis，查看是否有数据压入

[[email protected] ~]# /app/tools/redis-3.0.7/src/redis-cli

127.0.0.1:6379> llen syslog

(integer) 1255    

启动logstash

[[email protected] ~]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/test.conf

如果定义的配置文件有问题，查看logstash日志

[[email protected] ~]# tail /var/log/logstash/logstash-plain.log

配置正确后可以查看redis的syslog索引

[[email protected] ~]# /app/tools/redis-3.0.7/src/redis-cli

127.0.0.1:6379> llen syslog

(integer) 0

127.0.0.1:6379> 

就此elk+redis+filebeat搭建完毕
