[root@s1-prod-it-web01 opt]# tree -L 1 elasticsearch/
elasticsearch/ ├── bin ├── config ├── lib ├── LICENSE.txt ├── modules ├── NOTICE.txt ├── plugins └── README.textile 由于 elasticsearch默认不能使用root用户启动，先创建用户useradd elasticsearch
授权主程序目录
chown -R elasticsearch:elasticsearch /opt/elasticsearch/
创建数据存储目录 mkdir -p /var/lib/elasticsearch
授权存储目录 chown -R elasticsearch:elasticsearch /var/lib/elasticsearch
创建日志保存目录 mkdir -p /var/log/elasticsearch
授权日志保存目 chown -R elasticsearch:elasticsearch /var/lib/elasticsearch
创建进程PID文件目录 mkdir -p /var/run/elasticsearch
授权进程PID文件目录 chown -R elasticsearch:elasticsearch /var/run/elasticsearch
加入的Systemd Service ，配置文件如下，为了方便应用，已经参考官方教程编辑好了
