Use third-party software to upload the installation package to Linux and
decompress it to a specified folder. Here, the root user can decompress it to a specific folder.
tar -zxvf 安装文件 -C 指定目录位置

groupadd elsearchcreate an elsearch group,
useradd elsearch -g elsearchcreate an elsearch user,
passwd elsearchmodify the password,
modify the permission information of the decompressed file, and
chown -R elsearch:elsearch 解压文件
enter the bin folder

open a new window
and run after login.
curl http://localhost:9200

Enter the config folder and modify the elasticsearch.yml file.
Find the network, uncomment it, and modify it to 0.0.0.0.
If the network.host address is not localhost or 127.0.0.1, it will be regarded as a production environment, which requires higher environmental requirements and needs to modify the jvm .options file
Use the root user to modify the system configuration file
vim /etc/sysctl.conf
Add in the last line
vm.max_map_count=655360
Make the configuration effective
