一、环境准备

1.1、环境列表

1.2、修改主机名

#分别到主机执行
hostnamectl set-hostname es-node1
hostnamectl set-hostname es-node2
hostnamectl set-hostname es-node3

1.3、系统init

yum -y install wget vim lrzsz net-tools ntp
#修改yum源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 
yum clean all
yum -y update

# 关闭 防火墙
systemctl stop firewalld
systemctl disable firewalld

# 关闭 Selinux
setenforce 0
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

#时间同步
rm -f /etc/localtime
ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
systemctl start chronyd.service && systemctl enable chronyd.service

二、安装Docker

# 卸载旧版本
yum remove -y docker 
docker-client 
docker-client-latest 
docker-common 
docker-latest 
docker-latest-logrotate 
docker-logrotate 
docker-selinux 
docker-engine-selinux 
docker-engine

# 设置 yum repository
yum install -y yum-utils nfs-utils gfs2-utils glusterfs-fuse 
device-mApper-persistent-data 
lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

#镜像加速，请更换为自己公司的
mkdir -p /etc/docker /data/docker
tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://17i90p15.mirror.aliyuncs.com"],
  "insecure-registries": ["192.168.10.45"],
  "graph": "/data/docker"
}
EOF

# 安装并启动 docker
yum install -y docker-ce-18.09.7 docker-ce-cli-18.09.7 containerd.io
systemctl enable docker
systemctl start docker

三、操作系统限制修改

#文件包含限制一个进程可以拥有的VMA(虚拟内存区域)的数量
echo "vm.max_map_count=655360" >> /etc/sysctl.conf
sysctl -p

四、elasticsearch配置

4.1、创建目录

[root@es-node1 ~]# mkdir -p /data/elasticsearch/{data,logs,plugins}

4.2、配置文件

es-node1:

[root@es-node1 ~]# cd /data/elasticsearch/
[root@es-node1 elasticsearch]# cat > elasticsearch.yml <<  EOF
cluster.name: elasticsearch-cluster
node.name: es-node1

EOF

es-node2:

[root@es-node1 ~]# cd /data/elasticsearch/
[root@es-node1 elasticsearch]# cat > elasticsearch.yml <<  EOF

EOF

es-node3:

[root@es-node1 ~]# cd /data/elasticsearch/
[root@es-node1 elasticsearch]# cat > elasticsearch.yml <<  EOF
