ELK 6.x 部署

Elasticsearch版本：6.3.2

Kibana版本：6.3.2

1.es安装

按照官方提示操作即可。

通过yum安装或者下载tar包解压。

安装完成之后，需要修改一些配置

①修改文件 /etc/sysctl.conf

#添加以下内容
vm.max_map_count=

执行命令：

sysctl -p

这一步可以解决问题：max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

②修改文件/etc/security/limits.conf  （es为启动es程序的用户，默认是不允许使用root用户操作es的）

es soft nofile 65536
es hard nofile 65536
es soft nproc 2048
es hard nproc 2048
es soft memlock unlimited
es hard memlock unlimited

解决的问题：

[2018-08-14T09:35:24,417][WARN ][o.e.b.JNANatives         ] Unable to lock JVM Memory: error=12, reason=Cannot allocate memory
[2018-08-14T09:35:24,417][WARN ][o.e.b.JNANatives         ] This can result in part of the JVM being swapped out.
[2018-08-14T09:35:24,418][WARN ][o.e.b.JNANatives         ] Increase RLIMIT_MEMLOCK, soft limit: 65536, hard limit: 65536
[2018-08-14T09:35:24,418][WARN ][o.e.b.JNANatives         ] These can be adjusted by modifying /etc/security/limits.conf, for example:
	# allow user 'es' mlockall
	es soft memlock unlimited
	es hard memlock unlimited
[2018-08-14T09:35:24,418][WARN ][o.e.b.JNANatives         ] If you are logged in interactively, you will have to re-login for the new limits to take effect.

③修改文件 /etc/security/limits.d/90-nproc.conf （将1024改为2048）

* soft nproc 2048

④修改 es配置文件 config/elasticsearch.yml （根据安装方式不同，这个文件位置不同）

bootstrap.system_call_filter: false

解决的问题：

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