我是靠谱客的博主 斯文大米，最近开发中收集的这篇文章主要介绍ElasticSearch----使用docker-compose方式安装8.1.3版本的ElasticSearch集群，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

文章目录

      • 安装docker-compose
      • 使用docker-compose安装ElasticSearch

安装docker-compose

安装步骤：

（1）下载docker-compose

执行如下命令进行下载

curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

若速度较慢，可以使用如下命令：

curl -L "https://mirror.ghproxy.com/https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

（2）修改目录权限

chmod  x /usr/local/bin/docker-compose

（3）创建软连接

ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

（4）验证安装是否完成

执行如下命令，如果可以正常显示版本号，则表示已经完成

docker-compose --version

使用docker-compose安装ElasticSearch

（1）准备好环境变量

内容如下，保存在.env文件中，存放在一个空的目录中，这里注意密码需要给ELASTIC_PASSWORD 和 KIBANA_PASSWORD 配置一个比较强的，不能使用过于简单的密码,
此外，这里暴露端口是通过ES_PORT设置的，默认暴露9200端口，如果是其他端口需要修改下面变量文件中的ES_PORT值
kibana端口通过KIBANA_PORT设置，默认为5601，那么也可以设置为其他端口

# Password for the 'elastic' user (at least 6 characters)
ELASTIC_PASSWORD=xxxxxxxxxx

# Password for the 'kibana_system' user (at least 6 characters)
KIBANA_PASSWORD=xxxxxxxxxxx

# Version of Elastic products
STACK_VERSION=8.1.3

# Set the cluster name
CLUSTER_NAME=docker-cluster

# Set to 'basic' or 'trial' to automatically start the 30-day trial
LICENSE=basic
#LICENSE=trial

# Port to expose Elasticsearch HTTP API to the host
ES_PORT=9200
#ES_PORT=127.0.0.1:9200

# Port to expose Kibana to the host
KIBANA_PORT=5601
#KIBANA_PORT=80

# Increase or decrease based on the available host memory (in bytes)
MEM_LIMIT=1073741824

# Project namespace (defaults to the current folder name if not set)
#COMPOSE_PROJECT_NAME=myproject

（2）准备docke-compose.yml文件

如下，

version: "2.2"

services:
  setup:
    image: docker.elastic.co/elasticsearch/elasticsearch:${STACK_VERSION}
    volumes:
      - certs:/usr/share/elasticsearch/config/certs
    user: "0"
    command: >
      bash -c '
        if [ x${ELASTIC_PASSWORD} == x ]; then
          echo "Set the ELASTIC_PASSWORD environment variable in the .env file";
          exit 1;
        elif [ x${KIBANA_PASSWORD} == x ]; then
          echo "Set the KIBANA_PASSWORD environment variable in the .env file";
          exit 1;
        fi;
        if [ ! -f config/certs/ca.zip ]; then
          echo "Creating CA";
          bin/elasticsearch-certutil ca --silent --pem -out config/certs/ca.zip;
          unzip config/certs/ca.zip -d config/certs;
        fi;
        if [ ! -f config/certs/certs.zip ]; then
          echo "Creating certs";
          echo -ne 
          "instances:n"
          "  - name: es01n"
          "    dns:n"

          unzip config/certs/certs.zip -d config/certs;
        fi;
        echo "Setting file permissions"
        chown -R root:root config/certs;
        find . -type d -exec chmod 750 {} ;;
        find . -type f -exec chmod 640 {} ;;
        echo "Waiting for Elasticsearch availability";
        until curl -s --cacert config/certs/ca/ca.crt https://es01:9200 | grep -q "missing authentication credentials"; do sleep 30; done;
        echo "Setting kibana_system password";

        echo "All done!";

（3）配置vm.max_map_count 最小为262144

vi /etc/sysctl.conf

然后修改vm.max_map_count的值为262144，如果不存在，则直接增加以下内容

vm.max_map_count=262144

这种方式需要重启，一般情况下环境不允许重启的，因此这里可以继续使用如下命令配置

sysctl -w vm.max_map_count=262144

（4）启动服务

执行如下命令，启动服务

docker-compose up -d

（5）通过docker-compose ps 命令查看状态，如下，标志已经启动成功

[root@master es]# docker-compose ps
   Name                  Command                  State                             Ports
----------------------------------------------------------------------------------------------------------------
es_es01_1     /bin/tini -- /usr/local/bi ...   Up (healthy)   0.0.0.0:9200->9200/tcp,:::9200->9200/tcp, 9300/tcp
es_es02_1     /bin/tini -- /usr/local/bi ...   Up (healthy)   9200/tcp, 9300/tcp
es_es03_1     /bin/tini -- /usr/local/bi ...   Up (healthy)   9200/tcp, 9300/tcp
es_kibana_1   /bin/tini -- /usr/local/bi ...   Up (healthy)   0.0.0.0:5601->5601/tcp,:::5601->5601/tcp
es_setup_1    /bin/tini -- /usr/local/bi ...   Exit 0
[root@master es]#

(6) 然后再浏览器通过ip+端口即可访问了，比如这里 192.168.16.40:5601，然后输入用户名 elastic和配置的密码，如下

(7) 登录后结果如下
