由于elasticsearch权限控制严格，不能用root用户启动。

那就把elasticsearch这个文件夹授权个一个用户吧。

1、进入安装目录：

  1. lunadeMacBook-Air:local luna$ cd
  2. lunadeMacBook-Air:~ luna$ cd /usr/local/
  3. lunadeMacBook-Air:local luna$ ll
  4. total 0
  5. drwxr-xr-x  11 root  wheel  374  2  3 21:31 ./
  6. drwxr-xr-x@ 10 root  wheel  340  5 23  2017 ../
  7. drwxr-xr-x   3 root  wheel  102  8 29 14:01 CNCB/
  8. drwxr-xr-x   5 root  wheel  170  6 17  2016 bin/
  9. drwxr-xr-x@ 12 luna  wheel  408  2  4 17:27 elasticsearch-6.1.0/

  15. drwxr-xr-x   6 luna  wheel  204  2  3 21:08 tools/

2、授权 elasticsearch-6.1.0给我笔记本登陆用户luna

  1. lunadeMacBook-Air:local luna$ sudo chown -R luna elasticsearch-6.1.0/

3 、启动

  1. lunadeMacBook-Air:bin luna$ ./elasticsearch
