【ELK】ELK5.3搭建过程遇到的问题

elasticsearch 5.3 安装过程中遇到了一些问题,这里简单记录一下 。

问题一:警告提示

[2016-11-06T16:27:21,712][WARN ][o.e.b.JNANatives ] unable to install syscall filter: 

java.lang.UnsupportedOperationException: seccomp unavailable: requires kernel 3.5+ with CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER compiled in
at org.elasticsearch.bootstrap.Seccomp.linuxImpl(Seccomp.java:349) ~[elasticsearch-5.3.0.jar:5.3.0]
at org.elasticsearch.bootstrap.Seccomp.init(Seccomp.java:630) ~[elasticsearch-5.3.0.jar:5.3.0]

报了一大串错误,其实只是一个警告。

解决:使用心得linux版本,就不会出现此类问题了。

 

问题二:ERROR: bootstrap checks failed

max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
max number of threads [1024] for user [lishang] likely too low, increase to at least [2048]

解决:切换到root用户,编辑limits.conf 添加类似如下内容

vi /etc/security/limits.conf 

添加如下内容:

* soft nofile 65536

* hard nofile 131072

* soft nproc 2048

* hard nproc 4096

 

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

 

原因:
这是在因为Centos6不支持SecComp,而ES5.2.0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

 

问题三:max number of threads [1024] for user [lish] likely too low, increase to at least [2048]

解决:切换到root用户,进入limits.d目录下修改配置文件。

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

修改如下内容:

* soft nproc 1024

#修改为

* soft nproc 2048

 

问题四:max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]

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

然后,重新启动elasticsearch,即可启动成功。
