1、docker 安装部署

#更新 yum 源（一下均为 root 用户）
yum update
#安装 docker
yum remove docker-ce -y && yum install docker-ce -y && service docker start
#docker 启动
systemctl start docker
#docker 设置开机启动
systemctl enable docker
#docker 停止
systemctl stop docker
#有时候需要使用这种命令启动
systemctl start docker.service
systemctl enable docker.service

2、docker 镜像配置

在宿主机器编辑文件：vim /etc/docker/daemon.json

#请在该配置文件中加入（没有该文件的话，请先建一个）：
{
  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"]
}

3、elasticsearch 安装部署

3.1 拉去指定版本镜像

#拉取镜像
docker pull elasticsearch:7.7.0
#docker images 命令查看镜像列表 docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
elasticsearch 7.7.0 7ec4f35ab452 15 months ago 757MB

3.2 启动 es

#启动镜像
docker run --name elasticsearch -d -e ES_JAVA_OPTS="-Xms512m -Xmx512m" -e "discovery.type=single-node" -p 9200:9200 -p 9300:9300 elasticsearch:7.7.0

#--name 表示镜像启动后的容器名称
#-d: 后台运行容器，并返回容器 ID；
#-e: 指定容器内的环境变量
#-p: 指定端口映射，格式为：主机(宿主)端口:容器端口


#docker ps 命令查看 es 状态

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3e01cb2b81fb elasticsearch:7.7.0 "/tini -- /usr/local…" 24 minutes ago Up 19 minutes 0.0.0.0:9200->9200/tcp, :::9200->9200/tcp, 0.0.0.0:9300->9300/tcp, :::9300->9300/tcp elasticsearch

3.3 验证 es 是否成功

浏览器输入 IP:9200

4、docker 常用命令介绍

docker 启动
systemctl start docker

docker 设置开机启动
systemctl enable docker

docker 停止
systemctl stop docker

docker 查看版本
docker version

docker 容器操作
docker ps 查看任务
docker stop 容器 id 停止容器
docker start 容器 Id 启动容器
docker rm 容器 Id 删除容器
