附：

1、修改权限

chown elasticsearch /var/log/elasticsearch/elasticsearch_access.log

chgrp elasticsearch /var/log/elasticsearch/elasticsearch_access.log

2、max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]

vi /etc/security/limits.conf

3、max number of threads [1024] for user [elasticsearch] is too low, increase to at least [4096]

vi 90-nproc.conf

4、system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

Centos6不支持SecComp，而ES5.2.0默认bootstrap.system_call_filter为true

5、max file descriptors [65535] for elasticsearch process likely too low, increase to at least [65536]

elasticsearch hard nofile 65536 

elasticsearch soft nofile 65536 

禁用：在elasticsearch.yml中配置bootstrap.system_call_filter为false，注意要在Memory下面:

bootstrap.memory_lock: false

bootstrap.system_call_filter: false

6、外网访问9200端口

vi /etc/config/elasticsearch.yml

network.host: 0.0.0.0
