報了一大串錯誤,其實只是一個警告。ui
解決:使用心得linux版本,就不會出現此類問題了。ip
2:ERROR: bootstrap checks failed路由
max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]it
max number of threads [1024] for user [lishang] likely too low, increase to at least [2048]io
解決:切換到root用戶,編輯limits.conf 添加相似以下內容ast
vi /etc/security/limits.conf
添加以下內容:
* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096
要從新登陸
3: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
4: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。

通常狀況下是你的
