运行环境

虚拟化环境：Nutanix
操作系统：Redhat 7
Elascticsearch版本：7.1.1
资源：
CPU： 12 C
Memory： 108G
硬盘：本地100G，存储空间8T

1.安装Docker

1.1 首先更新操作系统
sudo yum update

1.2 添加yum仓库
sudo tee /etc/yum.repos.d/docker.repo <<-EOF
[dockerrepo]
name=DockerRepository
baseurl=https://yum.dockerproject.org/repo/main/centos/7
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
EOF

1.3 安装Docker
sudo yum -y install docker-engine

1.4 启动Docker服务
sudo service docker start

2.安装docker-compose

2.1 下载当前稳定版本的compose up
$sudo curl -L &quot;https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$sudocurl−L"https://github.com/docker/compose/releases/download/1.24.0/docker−compose−(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
2.2 赋予执行权限
$sudo chmod +x /usr/local/bin/docker-compose
2.3 检查compose是否正常安装（如果不报错即正常安装）
$docker-compose

3.获取elasticsearch镜像

docker pull docker.elastic.co/elasticsearch/elasticsearch:7.1.1

4.修改vm.max_map_count（如果不该会报错）

sysctl -w vm.max_map_count=262144 -----（临时）
###------
vi /etc/sysctl.conf
vm.max_map_count=262144
------永久###
检查是否成功
$ grep vm.max_map_count /etc/sysctl.conf
显示为vm.max_map_count=262144即为正常

5.创建用于存放数据的文件夹

mkdir -p /data/es-data/
递归将文件夹权限修改为777，否则会报错
chmod -R 777 /data
mount x.x.x.x:/vol/syslog_vol /data/es-data/
df -h 检查是否挂载成功
cd /data/es-data
mkdir es01
mkdir es02
mkdir es03
chmod 777 es01
chmod 777 es02
chmod 777 es03

6.禁用swap，修改-nofile

vi /etc/fstab
注释掉swap行（elk官网推荐）
vi /etc/security/limits.conf
-nofile 65535

7.编辑3节点ElasticSearch_docker-compose up 启动文件

vi docker-compose.yml
version: ‘2.2’
services:
es01:
image: docker.elastic.co/elasticsearch/elasticsearch:7.1.1
container_name: es01
environment:
- node.name=es01

ulimits:
memlock:

nofile:
soft: 65536
hard: 65536
volumes:

networks:
- esnet

volumes:
esdata01:
driver: local
esdata02:

8.启动集群

在docker-compose.yml同目录下运行
docker-compose up
