elasticsearch 安裝及踩坑
問題二: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]
解決:切換到root使用者,編輯limits.conf 新增類似如下內容
vi /etc/security/limits.conf
新增如下內容:
* 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使用者,進入limits.d目錄下修改配置檔案。
vi /etc/security/limits.d/90-nproc.conf
修改如下內容:
* soft nproc 1024
#修改為
* 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使用者修改配置sysctl.conf
vi /etc/sysctl.conf
新增下面配置:
vm.max_map_count=655360
並執行命令:
sysctl -p
然後,重新啟動elasticsearch,即可啟動成功。
