微服务-1、环境搭建

一、docker和docker-compost

# 使用yum安装docker
yum -y install docker
# 启动
systemctl start docker.service
# 设置为开机自启动
systemctl enable docker.service

# 下载docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# 添加可执行权限(这里不懂可以看一下菜鸟教程-linux教程-文件权限)
sudo chmod +x /usr/local/bin/docker-compose
# 查看docker-compose版本
docker-compose --version

二、docker来快速部署ElasticSearch到Linux上

version: '3.4'

services:
  elasticsearch:
    image: slideroom/elasticsearch:98
    environment:
      bootstrap.memory_lock: 'true'
      discovery.type: single-node
      ES_JAVA_OPTS: '-Xms512m -Xmx512m'
      xpack.security.enabled: 'false'
    ports:
      - 9200:9200
      - 9300:9300
    ulimits:
      memlock:
        soft: -1 
        hard: -1
    volumes:
      - esdata:/usr/share/elasticsearch/data

  kibana:
    depends_on:
      - elasticsearch
    image: slideroom/kibana:116
    ports:
      - 5601:5601
 
volumes:
  esdata:
    driver: local
  appdata:
    driver: local

注意：复制粘贴记得检查

通过一句简单的命令：docker-compose up -d 即可快速启动ElasticSearch和Kibana

 ui 是kibana

 访问9200表示安装成功

 访问9300  9300 是es 集群用的

 你把日志写在es，kibana 去查询，kibana只是作为一个展示用的

二、写入

1、通过Nuget安装Nlog依赖包

NLog.Web.AspNetCore
Nlog.Extensions.Logging

如图所示
