配置elasticsearch通用配置
配置java运行内存大小，修改/etc/elasticsearch/jvm.options文件中-Xms -Xmx的值，为java虚拟机运行的内存最小和最大值，必须相同。其他使用默认值即可。
[root@es-2 elasticsearch]# cat /etc/elasticsearch/jvm.options |grep "^-Xm"-Xms6g-Xmx6g
创建elasticsearch运行的日志路径和数据路径
[root@es-2 elasticsearch]# mkdir /data/es-data[root@es-2 elasticsearch]# mkdir /data/es-log[root@es-2 elasticsearch]# chown -R elasticsearch.elasticsearch /data
