使用Docker镜像部署ELK日志系统

https://www.cnblogs.com/xbblogs/p/10775908.html

https://www.liuyixiang.com/post/69592.html

使用Docker部署elasticsearch、logstash、kibana

指定版本：6.7.1 （建议使用同一的版本、屏蔽三个软件间的不兼容性）

下载镜像：

docker pull elasticsearch:6.7.1 docker pull logstash:6.7.1 docker pull kibana:6.7.1  

修改vm.max_map_count

vim /etc/sysctl.conf 添加配置：vm.max_map_count=262144 执行命令，确保生效配置生效： sysctl -p 依据服务器配置而定  

es集群

这里es集群用了3个节点，配置文件放在 /root/es/config/ 目录下，

注意：es是不允许使用root用户启动的，/root/es/config/  目录最好改成 777权限，

启动当前配置文件的es命令：

　　docker run -e ES_JAVA_OPTS="-Xms512m -Xmx512m" -d -p 9200:9200 -p 9300:9300 -v /root/es/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /root/es/data1:/usr/share/elasticsearch/data --name ES01 elasticsearch:6.7.1

启动当前配置文件的es命令：

　　docker run -e ES_JAVA_OPTS="-Xms512m -Xmx512m" -d -p 9202:9202 -p 9302:9302 -v /root/es/config/es3.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /root/es/data3:/usr/share/elasticsearch/data --name ES03 elasticsearch:6.7.1     1、-e JAVA_OPTS="-Xms512m -Xmx512m" 是配置当前es使用jvm的最大内存，内存配置过低会导致CPU非常高，如果服务器内存很大可配置2~4g 2、-p 9200:9200 -p 9300:9300  9200是es提供给外部的通讯端口，9300是es节点之间的通讯端口 3、 -v /root/es/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml  指定启动的配置文件 4、-v /root/es/data1:/usr/share/elasticsearch/data 指定es的数据挂载到当前服务器的目录 5、--name ES01  当前镜像的名字  

kibana

kibana.yml配置文件内容：  

server.name: kibana
server.host: "0"

启动kibana

　　docker run --name kibana -v /root/kibana/config:/usr/share/kibana/config -p 5601:5601 -d kibana:6.7.1  

logstash

把images中的配置文件拷贝出来： 1. 先运行一个logstash实例 2. docker cp 容器id:/usr/share/logstash/config /root/logstash/config      docker cp 容器id:/usr/share/logstash/pipeline /root/logstash/pipeline

pipeline/logstash.conf

 

input{
    http{
        host => "0.0.0.0"
        port => 5050
        additional_codecs => {"application/json"=>"json"}
        codec => "plain"
        threads => 4
        ssl => false
    }
}
output {
    elasticsearch {
