【大数据开发运维解决方案】Elasticsearch+Logstash+Kibana(6.7.1版本)安装部署_es6.7.1

Elasticsearch+Logstash+Kibana(6.7.1版本)安装部署

目前Elasticsearch、Logstash、Kibana三个组件都准备安装在虚拟机供个人学习使用。

一、部署Elasticsearch

1、下载安装包

官网下载地址：
ES下载官网
选择Elasticsearch组件

2、新增ES用户

因为elasticsearch不允许root用户启动，所以需要创建新的用户和组。

[root@s133061 elasticsearch-6.7.1]# useradd es
[root@s133061 elasticsearch-6.7.1]# passwd es
Changing password for user es.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.

3、上传解压安装包

[root@s133061 elk]# pwd
/hadoop/elk
[root@s133061 elk]# ls
elasticsearch-6.7.1.tar.gz  kibana-6.7.1-linux-x86_64.tar.gz  logstash-6.7.1.tar.gz

[root@s133061 elk]# tar -xvf elasticsearch-6.7.1.tar.gz -C /home/es/

4、#修改elasticsearch的权限给es用户和组

[root@s133061 elk]# cd /home/es/
[root@s133061 es]# ls
elasticsearch-6.7.1
[root@s133061 es]# chown -R es:es elasticsearch-6.7.1
[root@s133061 es]# ll
total 0
drwxr-xr-x 8 es es 143 Apr  3  2019 elasticsearch-6.7.1

5、修改配置文件

[root@s133061 es]# cd elasticsearch-6.7.1/
[root@s133061 elasticsearch-6.7.1]# ls
bin  config  lib  LICENSE.txt  logs  modules  NOTICE.txt  plugins  README.textile
[root@s133061 elasticsearch-6.7.1]# cd config/
[root@s133061 config]# ls
elasticsearch.yml  jvm.options  log4j2.properties  role_mapping.yml  roles.yml  users  users_roles
切换用户为es后创建目录：
先创建es的日志目录和数据存放目录：
[es@s133061 elasticsearch-6.7.1]$ mkdir -p data/es
[es@s133061 elasticsearch-6.7.1]$ mkdir -p data/logs/es
接下来修改配置文件：
[es@s133061 elasticsearch-6.7.1]$ pwd
/home/es/elasticsearch-6.7.1
[es@s133061 elasticsearch-6.7.1]$ cd config/
[es@s133061 config]$ vim elasticsearch.yml
修改部分配置如下：
path.data: /home/es/elasticsearch-6.7.1/data/es
path.logs: /home/es/elasticsearch-6.7.1/data/logs/es
--目的是使ES支持跨域请求
network.host: 10.241.133.61
http.port: 9200
http.cors.enabled: true
http.cors.allow-origin: '*'

6、修改linux系统资源配置

下面是本人在上面配置修改后启动报的错误以及解决方案，建议各位先按照下面配置修改自己配置再启动es。

a.max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]
修改 /etc/security/limits.conf 文件，增加配置，来改变用户 es 每个进程最大同时打开文件数的大小：
es soft nofile 65535 
es hard nofile 65537
可切换到es用户下，然后通过下面2个命令查看当前数量：
ulimit -Hn
ulimit -Sn
注意：用户退出重新登录后配置才会刷新生效。

b. max number of threads [3818] for user [es] is too low, increase to at least [4096]
最大线程个数太低。修改配置文件 /etc/security/limits.conf ，增加配置：
es - nproc 4096 
# 或者 
es soft nproc 4096 
es hard nproc 4096
可切换到es用户下，然后通过下面2个命令查看当前最大线程数：
ulimit -Hu
ulimit –Su
注意：用户退出重新登录后配置才会刷新生效。
c. max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
修改 /etc/sysctl.conf 文件，在文末增加配置
vm.max_map_count=262144
执行命令sysctl -p生效。
d. memory locking requested for elasticsearch process but memory is not locked
修改 /etc/security/limits.conf 文件，增加配置：
* soft memlock unlimited 
* hard memlock unlimited

[es@s133061 bin]$ nohup ./elasticsearch &
[1] 23324
[es@s133061 bin]$ nohup: ignoring input and appending output to ‘nohup.out’

访问url:http://10.241.133.61:9200/
出现下面提示代表es启动成功：

二、Logstash部署

1、下载安装包

官网下载地址：
ES下载官网
选择logstash组件

2、解压缩

[root@s133061 elk]# pwd
/hadoop/elk
[root@s133061 elk]# tar -xvf logstash-6.7.1.tar.gz
[root@s133061 elk]# ls
elasticsearch-6.7.1.tar.gz  kibana-6.7.1-linux-x86_64.tar.gz  logstash-6.7.1  logstash-6.7.1.tar.gz
[root@s133061 elk]# cd logstash-6.7.1/
[root@s133061 logstash-6.7.1]# ls
bin  config  CONTRIBUTORS  data  Gemfile  Gemfile.lock  lib  LICENSE.txt  logstash-core  logstash-core-plugin-api  modules  NOTICE.TXT  tools  vendor  x-pack
[root@s133061 logstash-6.7.1]# mkdir zhaoyd

3、在ES创建索引

创建索引
[root@s133061 zhaoyd]#  curl -XPUT http://10.241.133.61:9200/zydtest
{"acknowledged":true,"shards_acknowledged":true,"index":"zydtest"}
查询刚刚创建的索引：
[root@s133061 zhaoyd]# curl -XGET "http://10.241.133.61:9200/zydtest/_search?pretty"
{
  "took" : 85,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 0,
    "max_score" : null,
    "hits" : [ ]
  }
}

编辑测试数据：

[root@s133061 zhaoyd]# cat log.log
2020-12-14T10:50:58.000+00:00 INFO this is a test! 10.241.133.13

input{
        file{
                path => "/hadoop/elk/logstash-6.7.1/zhaoyd/log.log"
                start_position => "beginning"
        }
}
filter{
        grok{
                match=>{ "message" => "%{TIMESTAMP_ISO8601:timestamp} %{LOGLEVEL:log-level} %{DATA:message} %{IP:address}" }
        }
}
output{
        elasticsearch{
                hosts => "10.241.133.61:9200"
                index => "zydtest"
        }
