這裏 java-1.8.0-openjdk-devel
非必須安裝,但之後安裝插件時可能會須要 Java 的編譯器(javac),所以建議提早安裝好。node

官方提供了生產環境下 Elasticsearch 所在操做系統的相關建議,詳見這裏cors
1. 跨域支持 根據官網建議添加了以下配置到elasticsearc.yml主配置文件 http.cors.enabled: true http.cors.allow-origin: "*" 問題二: max number of threads [1024] for user [elasticsearch] is too low, increase to at least [2048] 解決方法:進入limits.d下的配置文件:vim /etc/security/limits.d/90-nproc.conf ,修改配置以下: vim /etc/security/limits.d/90-nproc.conf * soft nproc 1024 修改成: * soft nproc 2048 問題三: max file descriptors [64000] for elasticsearch process is too low, increase to at least [65536] 解決辦法: 一、虛擬內存設置,編輯 /etc/sysctl.conf ,追加: vm.max_map_count=262144 二、修改文件句柄限制,編輯 /etc/security/limits.conf ,追加: root># vim /etc/security/limits.conf * soft nofile 65536 * hard nofile 65536 問題四: elasticsearch5.0啓動失敗,出現以下提示: 一、Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000085330000, 2060255232, 0) failed; error='Cannot allocate memory' (errno=12) 因爲elasticsearch5.0默認分配jvm空間大小爲2g,修改jvm空間分配 # vim config/jvm.options -Xms2g -Xmx2g 修改成 -Xms512m -Xmx512m
