安装es集群注意的问题

安装软件应看软件的日志----方便排查问题，看表象界面的日志没多大作用---日志目录配置文件都会设置

1，su - es -c "/usr/share/elasticsearch/bin/elasticsearch -d"---不能用root用户启动应该新加es用户组 can not run elasticsearch as root

2，chmod -R 775 /usr/share/elasticsearch/config/scripts----------拷贝etc目录配置文件的时候注意层级（外面不能套有elastic文件），并赋予权限 --- java.nio.file.AccessDeniedException: /usr/share/elasticsearch/config/scripts

3，ulimit -Hn 65536

4，vim /etc/security/limits.conf 追加hard nofile 65536设置大----[1]: max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]

5，nethost用ip或者0.0.0.0都可远程访问
