7 新增用户

useradd estest
passwd estest

chmod 777 /*

8 切换用户

su  estest

9 启动保错权限不够

$ ./elasticsearch

10 为用户赋予执行当前文件的权限

 chown -R estest:estest  /soft/*

11 开启9200端口

sbin/iptables -I INPUT -p tcp --dport 9200  -j ACCEPT

/etc/rc.d/init.d/iptables save

/etc/rc.d/init.d/iptables restart

12 查看是否可以安装正常

curl 'http://localhost:9200/?pretty'

[root@demo /]# curl 'http://localhost:9200/?pretty'
{
  "name" : "wqwDnl5",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "ku_SIYNoSWGHuo4aXlF0sA",
