使用的elk是6.4.3版本,安装java8,可以使用yum install tomcat就会自动安装了

 1、首先下载elasticsearch-6.4.3、logstash-6.4.3、kibana-6.4.3,不要放在root目录下

2、解压完成后做如下修改

解压后进入config目录:cd elasticsearch-6.4.2/config,vim elasticsearch.yml 修改配置文件,在最下面加入如下几行:

 
network.host: 0.0.0.0
 
http.port: 9200
 
http.cors.enabled: true
 
http.cors.allow-origin: "*"

3、不能使用root用户启动,需要创建新用户

创建elsearch用户组及elsearch用户

groupadd elsearch

useradd elsearch -g elsearch -p elasticsearch

更改elasticsearch-6.4.3文件夹及内部文件的所属用户及组为elsearch:elsearch

cd切换到elasticsearch-6.4.3的父路径下

chown -R elsearch:elsearch elasticsearch-6.4.3

切换到elsearch用户再启动

su elsearch

cd elasticsearch-6.4.3/bin

sh elasticsearch &

4、完成之后启动

在bin目录下执行./elasticsearch &

 

5、可能会遇到错误,如下解决

启动失败,检查没有通过,报错

[2018-05-18T17:44:59,658][INFO ][o.e.b.BootstrapChecks    ] [gFOuNlS] bound or publishing to a non-loopback address, enforcing bootstrap checks
ERROR: [2] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]

[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]

编辑 /etc/security/limits.conf,追加以下内容;
* soft nofile 65536
* hard nofile 65536

centos7.6版本需要添加
* soft nofile 655350
* hard nofile 655350


此文件修改后需要重新登录用户,才会生效 [2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] 编辑 /etc/sysctl.conf,追加以下内容: vm.max_map_count=655360 保存后,执行: sysctl -p 重新启动,成功。 bin/elasticsearch &

6、kibana启动

按照上面的操作,可以先切回root用户了:su root     需要输入root密码

然后cd kibana-6.4.3-linux-x86_64/config/  进入kibana的配置文件夹,

 vim kibana.yml  编辑配置文件,在最后面加上如下配置就行:

server.port: 5601
server.host: "0.0.0.0"
elasticsearch.url: "http://localhost:9200"
kibana.index: ".kibana"

cd命令进入bin目录,

sh kibana &   启动kibana

 

7、配置logstash

cd logstash-6.4.2/bin/进入bin目录

新建文件 vim logstash1.conf ,写入内容(监听tomcat的日志):

input {
    file {
        path => "/usr/share/tomcat/logs/*.log"
        start_position => beginning
    }
}
filter {
 
}
output {
    elasticsearch {
    hosts => "localhost:9200"
    }
 
}

启动logstash:sh logstash -f logstash.conf  &

如果提示--path.data的问题,则需要指定path.data的路径,随便找个路径就行,

我的是这样启动:sh logstash -f logstash1.conf  --path.data=/home/elk/logstash-6.4.3/logs &

完了可以看到kibana上面有logstash推送过去的日志了

配合mysql存储

wget https://cdn.mysql.com//Downloads/Connector-J/mysql-connector-java-5.1.49.tar.gz  -O /home/liyong/mysql-connector.tar.gz

可以把解压后的mysql-connector-java-5.1.46-bin.jar复制到bin目录,方便启动

在bin目录新建配置文件    vim mysql-logstash.cnf ,写入:

input {
  jdbc {
    jdbc_driver_library => "mysql-connector-java-5.1.46-bin.jar"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://ip:3306/db_name"
    jdbc_user => "jdbc_user"
    jdbc_password => "jdbc_password"
    schedule => "* * * * *"
    statement => "SELECT * FROM table WHERE 时间字段 >= :sql_last_value"
    use_column_value => true
    tracking_column_type => "timestamp"
    tracking_column => "时间字段"
    last_run_metadata_path => "syncpoint_table"
  }
}
 
 
output {
  elasticsearch {
    hosts => "localhost:9200"
    index => "索引名称"
    document_id => "%{主键字段}"
  }
}

 

需要先把logstash停了,在重启

netstat -ntlp  命令查看端口为9600的进程

重新执行即可
sh /usr/elk/logstash-6.4.3/bin/logstash -f /usr/elk/logstash-6.4.3/bin/mysql-logstash.cnf --path.data=/usr/elk/logstash-6.4.3/logs &
