Linux安装ES问题集锦

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-5.0.0.jar:5.0.0]
at org.elasticsearch.bootstrap.Seccomp.init(Seccomp.java:630) ~[elasticsearch-5.0.0.jar:5.0.0]

报了一大串错误，其实只是一个警告。
解决：使用新的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]

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

问题三：ERROR: bootstrap checks failed
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：ERROR: bootstrap checks failed
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。

问题五：bootstrap checks failed
system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

问题原因：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。详见 ：https://github.com/elastic/elasticsearch/issues/22899

解决方法：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

问题六：局域网不能访问elasticsearch

修改elasticsearch.yml中的Network

#network.host: 192.168.0.1 删除#并修改ip为当前服务器IP，如

network.host: 192.168.111.12

#http.port: 9200 同事可以修改端口

问题六：局域网不能访问kibana

修改kibana.yml中的

#server.host: "localhost"

#elasticsearch.url: "http://localhost:9200"

 

Done！
