标签：pre 创建 filters filter too ESS roc config 配置
前言：选择安装包的时候，尽量选择用rpm包去安装，因为里面的一些配置，rpm包管理会帮你做好。[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]<br/>[2]: max number of threads [1024] for user [es] is too low, increase to at least [4096]<br/>* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096问题二:max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]
原因：最大虚拟内存区域vm.max_map_count太低
解决：切换到root用户修改配置sysctl.conf
vi /etc/sysctl.conf
添加下面配置：
vm.max_map_count=655360
并执行命令：
sysctl -p
问题三：system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk<br/>
原因：因为Centos6不支持SecComp，而ES5.2.1默认bootstrap.system_call_filter为true进行检测，所以导致检测失败，失败后直接导致ES不能启动
解决：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标签：pre 创建 filters filter too ESS roc config 配置
