docker-compose安装elk

docker pull elasticsearch:7.6.2
docker pull kibana:7.6.2
docker pull logstash:7.6.2

• 需要设置系统内核参数，否则会因为内存不足无法启动

# 改变设置
sysctl -w vm.max_map_count=262144
# 使之立即生效
sysctl -p

• 需要创建/mydata/elasticsearch/data目录并设置权限，否则会因为无权限访问而启动失败

# 创建目录
mkdir /mydata/elasticsearch/data/
# 创建并改变该目录权限
chmod 777 /mydata/elasticsearch/data

创建Logstash的配置文件logstash.conf中output节点下的Elasticsearch连接地址为es:9200。

input {
  tcp {
    mode => "server"
    host => "0.0.0.0"
    port => 4560
    codec => json_lines
    type => "debug"
  }
  tcp {
    mode => "server"
    host => "0.0.0.0"
    port => 4561
    codec => json_lines
    type => "error"
  }
  tcp {
    mode => "server"
    host => "0.0.0.0"
    port => 4562
    codec => json_lines
    type => "business"
  }
  tcp {
    mode => "server"
    host => "0.0.0.0"
    port => 4563
    codec => json_lines
    type => "record"
  }
}
filter{
  if [type] == "record" {
    mutate {
      remove_field => "port"
      remove_field => "host"
      remove_field => "@version"
    }
    json {
      source => "message"
      remove_field => ["message"]
    }
  }
}
output {
  elasticsearch {
    hosts => "es:9200"
    index => "mall-%{type}-%{+YYYY.MM.dd}"
  }
}

创建/mydata/logstash目录，并将Logstash的配置文件logstash.conf拷贝到该目录。

mkdir /mydata/logstash

文件上传的linux服务器上，执行docker-compose up

指定yml文件名执行命令：

docker-compose -f docker-compose-env.yml up -d
