centos6安装ElasticSearch5.6.5错误记录

在centos6安装ES的时候遇到不少问题。这里记录日志。以后安装一定要升级centos7，别说啥稳定问题了，该升级就升级。

[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536] [2]: max number of threads [1024] for user [es] is too low, increase to at least [2048] [3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] [4]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk 

解决方案：

vim config/elasticsearch.yml

追加

bootstrap.memory_lock: false bootstrap.system_call_filter: false

vi /etc/security/limits.conf

追加

* soft nofile 65536 * hard nofile 131072 * soft nproc 2048 * hard nproc 4096

vi /etc/security/limits.d/90-nproc.conf
追加

修改如下内容： * soft nproc 1024 #修改为 * soft nproc 2048

vi /etc/sysctl.conf
追加

vm.max_map_count=655360

sysctl -p
