1、docker 安装

第一种方式

curl -fsSL get.docker.com -o get-docker.sh 
chmod 777 get-docker.sh 
sh get-docker.sh 
systemctl start docker 
systemctl enable docker

第二种方式

yum -y install yum-utils yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin ​

通过阿里云的 SWR 个人镜像加速

vi /etc/docker/daemon.json
{    
    "registry-mirrors": ["https:// 个人阿里云地址.mirror.swr.myhuaweicloud.com"] 
}

重启 docker

systemctl restart docker 
systemctl enable docker

2、配置文件修改

vim /etc/security/limits.conf

* soft nofile 65536
* hard nofile 131072

vim /etc/sysctl.conf

vm.max_map_count=655360 
sysctl -p

3、es 目录配置

mkdir -p /usr/local/es_cluster/node_1/data
mkdir -p /usr/local/es_cluster/node_1/logs
mkdir -p /usr/local/es_cluster/node_1/plugins 
mkdir -p /usr/local/es_cluster/node_1/esconfig 
chmod -R 777 /usr/local/es_cluster/node_1/{data,logs,plugins,esconfig}

4、es 分词器下载安装

cd /opt

wget  https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.9.3/elasticsearch-analysis-ik-7.9.3.zip
unzip /opt/elasticsearch-analysis-ik-7.9.3.zip -d /usr/local/es_cluster/node_1/plugins 
unzip /opt/elasticsearch-analysis-ik-7.9.3.zip -d /usr/local/es_cluster/node_2/plugins 
unzip /opt/elasticsearch-analysis-ik-7.9.3.zip -d /usr/local/es_cluster/node_3/plugins ​

5、拉取 es,kibana 镜像

docker pull elasticsearch:6.8.13
docker pull kibana:6.8.0 ​
 或  docker pull docker.elastic.co/logstash/logstash:6.8.0
docker pull docker.elastic.co/kibana/kibana:6.8.0

6、依次创建 node-1，2，3 容器

docker run -d --privileged=true \
--ulimit nofile=655350:655350 \
--name es_test \
--network host \
--cpus=16 --memory=64g --memory-swap=64g \
--oom-kill-disable --ulimit memlock=-1:-1 \
-e TZ=Asia/Shanghai \
-v /usr/local/es_cluster/node_1/config:/usr/share/elasticsearch/config \
-v /usr/local/es_cluster/node_1/plugins:/usr/share/elasticsearch/plugins \
-v /usr/local/es_cluster/node_1/logs:/usr/share/elasticsearch/logs \
-v /usr/local/es_cluster/node_1/data:/usr/share/elasticsearch/data \
elasticsearch:6.8.13

7、验证

8、 配置文件修改
