ELK 是由三部分组成的一套日志分析系统,

 Elasticsearch: 基于json分析搜索引擎,Elasticsearch是个开源分布式搜索引擎,它的特点有:分布式,零配置,自动发现,索引自动分片,

                          索引副本机制,restful风格接口,多数据源,自动搜索负载等。

Logstash:动态数据收集管道,Logstash是一个完全开源的工具,它可以对你的日志进行收集、分析,并将其存储供以后使用

Kibana:可视化视图,将elasticsearh所收集的data通过视图展现。kibana 是一个开源和免费的工具,它可以为 Logstash 和
              ElasticSearch 提供的日志分析友好的 Web 界面,可以帮助您汇总、分析和搜索重要数据日志。

 

一、使用docker集成镜像
安装docker
elk集成镜像包 名字是 sebp/elk


1.安装 docke、启动

yum install docke

service docker start

 

2.下载 sebp/elk

docker pull sebp/elk

无法下载、报错 :
unauthorized: authentication required
这是国外网络的问题

 

 

解决1 用网易镜像
vim /etc/docker/daemon.json 这个json文件不存在的,不需要担心,直接编辑
把下面的贴进去,保存,重启即可

{
"registry-mirrors": [ "http://hub-mirror.c.163.com"]
}

# service docker restart

没效果,还是下不来


解决2 用阿里云镜像加速

注册一个阿里云账号,登陆
到这里复制自己的加速地址

然后
安装/升级你的Docker客户端
  • 推荐安装1.10.0以上版本的Docker客户端,参考文档 docker-ce
如何配置镜像加速器
  • 针对Docker客户端版本大于1.10.0的用户

    您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器:

    sudo mkdir -p /etc/docker
    sudo tee /etc/docker/daemon.json <<-‘EOF‘
    {
      "registry-mirrors": ["https://34sii7qf.mirror.aliyuncs.com"]
    }
    EOF
    sudo systemctl daemon-reload
    sudo systemctl restart docker

下载:
# docker pull sebp/elk

docker.io/sebp/elk    latest              4b52312ebe8d     12 days ago           1.15 GB

 

3.启动镜像

# docker run -p 5601:5601 -p 9200:9200 -p 5044:5044 -it --name elk sebp/elk

 

报错:

Couln‘t start Elasticsearch. Exiting.
Elasticsearch log follows below.

原因:

 

waiting for Elasticsearch to be up (xx/30) counter goes up to 30 and the container exits with Couln‘t start Elasticsearch. Exiting. and Elasticsearch‘s logs are dumped, then read the recommendations in the logs and consider that they must be applied.

 

In particular, in case (1) above, the message max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]means that the host‘s limits on mmap counts must be set to at least 262144.

 

Docker至少得分配3GB的内存;

 

Elasticsearch至少需要单独2G的内存;

 

vm.max_map_count至少需要262144,修改vm.max_map_count 参数

 

解决:

      # vi /etc/sysctl.conf

      末尾添加一行
      vm.max_map_count=262144

      查看结果
        # sysctl -p

         vm.max_map_count = 262144

重新启动:

# docker run -p 5601:5601 -p 9200:9200 -p 5044:5044 -it --name elk sebp/elk
