docker-compose安装7.12.0版ES+kibana【单点模式】

---

一、前置条件

1. 安装docker-compose，可以参考这篇文章 https://blog.youkuaiyun.com/weixin_43721000/article/details/125425947

---

二、安装ES+kibana

1.创建并进入项目根目录

mkdir -p /cxstar/es_kibana_7.12.0
cd /cxstar/es_kibana_7.12.0

2.创建 docker-compose.yml 文件

vim docker-compose.yml

内容如下

version: '3.5'                                    # docker-compose版本

services:
 elasticsearch:
  image: elasticsearch:7.12.0                     # 指定es基础镜像
  restart: always                                 # 开机自启
  networks:
   - es-kibana-net                                # 网络配置
  container_name: es7120                          # 容器名
  volumes:
   - ./data:/usr/share/elasticsearch/data         # 数据目录映射
   - ./plugins:/usr/share/elasticsearch/plugins   # 插件目录映射
  environment:
   - "ES_JAVA_OPTS=-Xms1024m -Xmx1024m"           # 1G内存
   - discovery.type=single-node                   # 单点模式
  ports:
    - '9200:9200'                                 # java、集群通信端口
    - '9300:9300'                                 # http通信端口
  privileged: true                                # root启动

 kibana:
  image: kibana:7.12.0                            # 指定kibana基础镜像
  restart: always                                 # 开机自启
  networks:
   - es-kibana-net                                # 网络配置
  container_name: kibana7120                      # 容器名
  ports:
   - '5601:5601'								  # kibana端口

networks:
  es-kibana-net:
    name: es-kibana-net                           # 创建网络

3.启动容器

docker-compose up -d

到此一般就安装完成了，但是可能会遇到下面的问题：

常见安装失败问题

启动后执行 docker ps 命令发现没有容器，启动失败了。
执行 docker logs -f <容器id> 查看容器日志，报错如下

说明es没有权限操作挂载目录，无法绑定节点，赋予data目录权限即可

sudo chmod 777 /cxstar/es_kibana_7.12.0/data

删除es的docker容器，再次执行容器启动命令

启动成功

四、访问测试

1. 访问5601端口，选择 Explore on my own
   
2. 选择菜单栏下的 Dev Tools
   
3. 请求es
