步骤如下：

1. 下载最新版本的Elasticsearch：

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.14.0-linux-x86_64.tar.gz

1. 解压文件并移动到合适的安装目录：

tar -zxvf elasticsearch-7.14.0-linux-x86_64.tar.gz
mv elasticsearch-7.14.0 /opt

1. 创建一个名为elasticsearch的系统用户和组：

sudo groupadd elasticsearch
sudo useradd elasticsearch -g elasticsearch

1. 设置Elasticsearch数据和日志目录的权限：

sudo chown -R elasticsearch:elasticsearch /opt/elasticsearch-7.14.0/data /opt/elasticsearch-7.14.0/logs

1. 配置Elasticsearch：
   编辑/opt/elasticsearch-7.14.0/config/elasticsearch.yml文件，设置以下配置:

cluster.name: my-cluster
node.name: my-node
path.data: /opt/elasticsearch-7.14.0/data
path.logs: /opt/elasticsearch-7.14.0/logs

1. 创建systemd服务文件elasticsearch.service：

sudo vi /etc/systemd/system/elasticsearch.service

并添加以下内容：

[Unit]
Description=Elasticsearch
[Service]
Type=simple
User=elasticsearch
Group=elasticsearch
LimitMEMLOCK=infinity
Environment=ES_HOME=/opt/elasticsearch-7.14.0
Environment=ES_PATH_CONF=/opt/elasticsearch-7.14.0/config
Environment=PID_DIR=/opt/elasticsearch-7.14.0
ExecStart=/opt/elasticsearch-7.14.0/bin/elasticsearch
Restart=always
WorkingDirectory=/opt/elasticsearch-7.14.0
[Install]
WantedBy=multi-user.target

1. 启动并设置Elasticsearch开机自启动：

sudo systemctl daemon-reload
sudo systemctl enable elasticsearch
sudo systemctl start elasticsearch

完成以上步骤后，即可成功安装部署Elasticsearch7版本并加入systemctl进行管理。
