小结
本节对 ES 节点/集群部署所需环境参数及其意义进行了阐述，同时提供了最简初始化脚本和完整版初始化流程供参考。
安装实战
本节将对几个主流的 ES 安装部署的方式进行阐述，并会对节点的安装、部署、启动、停机等流程进行详细描述。
tar 包安装
下载链接（后面以 ES_DOWNLOAD_URL 指代）：
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.10.0-linux-x86_64.tar.gz
下载并解压：
l mkdir -p /usr/local/elasticsearch
l cd /usr/local/elasticsearch
l wget -c ${ES_DOWNLOAD_URL}
l tar vxf elasticsearch-7.10.0-linux-x86_64.tar.gz

解压出来的文件：

最简启动
1、确认自己处于 非 root 用户，否则后续启动会报错
2、cd elasticsearch-7.10.0
3、./bin/elasticsearch
4、如果要后台启动，只需在启动命令后面加上 -d
l ./bin/elasticsearch -d
l 完整路径 ./usr/local/elasticsearch/elasticsearch-7.10.0/bin/elasticsearch -d
5、在出现类似这些日志的时候，代表节点启动完成：

节点停机
1、ps -ef | grep elasticsearch | grep -v grep | awk '{ print$2 }' | xargs kill -15
2、没有后台启动的话，直接 ctrl + c 会输出类似以下的日志：
[2021-04-15T20:05:47,962][INFO ][o.e.x.m.p.NativeController] [esteam7002] Native controller process has stopped - no new native processes can be started [2021-04-15T20:05:47,964][INFO ][o.e.n.Node ] [esteam7002] stopping ...

rpm 包安装
下载链接（后面以 ES_DOWNLOAD_URL 指代）：
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.10.0-x86_64.rpm
下载并安装：
1、切换到 root 账户（否则无法进行安装）sudo -i
2、mkdir -p /usr/local/elasticsearch
3、cd /usr/local/elasticsearch
4、wget -c ${ES_DOWNLOAD_URL}
5、rpm -ivh elasticsearch-7.10.0-x86_64.rpm
安装成功日志
日志会根据当前操作系统的语言而显示不同的语言提示，本示例系统为中文：
[root@esteam7002 elasticsearch]# rpm -ivh elasticsearch-7.10.0-x86_64.rpm 警告：elasticsearch-7.10.0-x86_64.rpm: 头V4 RSA/SHA512 Signature, 密钥 ID d88e42b4: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:elasticsearch-0:7.10.0-1 ################################# [100%] ### NOT starting on installation, please execute the following statements to configure elasticsearch service to start automatically using systemd sudo systemctl daemon-reload sudo systemctl enable elasticsearch.service ### You can start elasticsearch service by executing sudo systemctl start elasticsearch.service Created elasticsearch keystore in /etc/elasticsearch/elasticsearch.keystore
最简启动
1、确认自己处于 root 用户，否则命令需要加 sudo 前缀
2、通过命令 systemctl start elasticsearch 启动
3、没有报错表明节点启动完成
ES 启动状态校验
1、同上节
节点停机
1、通过命令 systemctl stop elasticsearch 停止服务
2、没有报错表明节点停机完成
Docker 安装
下载对应镜像
docker pull elasticsearch:7.10.1
(可选)如果目标机器无法上网，可以尝试通过其他机器下载并导入镜像
1、在宿主机下载镜像 docker pull elasticsearch:7.10.1
2、把镜像导出为文件 docker save -o elasticsearch-7.10.1-image.tar docker.io/elasticsearch:7.10.1
3、把导出的文件拷贝到目标机器 scp elasticsearch-7.10.1-image.tar root@192.168.10.221:/tmp
4、登陆目标机器 ssh root@192.168.10.221
5、导入目标镜像 docker load < elasticsearch-7.10.1-image.tar
