Linux安装ElasticSearch 7.16.2

1、下载安装包

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.16.2-linux-x86_64.tar.gz

tar -xzf elasticsearch-7.16.2-linux-x86_64.tar.gz

cd elasticsearch-7.16.2/

2、创建普通用户

[root@localhost elasticsearch-7.16.2]# useradd liuhong

[root@localhost home]# passwd liuhong

[root@localhost home]# chmod -R 775 /home/software/

[root@localhost home]# su liuhong

解释：elasticsearch不能在root用户下执行，所以创建一个普通用户

3、启动服务

[liuhong@localhost home]$ cd software/elasticsearch-7.16.2/

[liuhong@localhost home]$ ./bin/elasticsearch

4、修改网络配置，使其他机器可访问

5、报错问题：
