Elasticsearch5.1 安裝問題集錦

 

elasticsearch 5.0 啓動過程有些問題,經過搜索找到了一篇文章,記錄一下供之後查閱參考,也但願能夠幫助遇到一樣問題的你。java

問題一:警告提示linux

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

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]elasticsearch

報了一大串錯誤,其實只是一個警告。ui

解決:使用新的linux版本,就不會出現此類問題了。spa

 

問題二:ERROR: bootstrap checks failedip

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]it

解決:切換到root用戶,編輯limits.conf 添加相似以下內容io

vi /etc/security/limits.conf ast

添加以下內容:

* soft nofile 65536

* hard nofile 131072

* soft nproc 2048

* hard nproc 4096

 

問題三:max number of threads [1024] for user [lish] likely too low, increase to at least [2048]

解決:切換到root用戶,進入limits.d目錄下修改配置文件。

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

修改以下內容:

* soft nproc 1024

#修改成

* soft nproc 2048

 

問題四:max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]

解決:切換到root用戶修改配置sysctl.conf

vi /etc/sysctl.conf 

添加下面配置:

vm.max_map_count=655360

並執行命令:

sysctl -p

而後,從新啓動elasticsearch,便可啓動成功。
