- 修改系統(tǒng)配置-limit數(shù)量 (開啟memory_lock時(shí)才需要)
vim /etc/security/limits.conf #添加以下內(nèi)容（需要重新登陸系統(tǒng)生效）
* soft nofile 75535
* hard nofile 75535
- 修改內(nèi)核參數(shù)vm.max_map_count(開啟memory_lock時(shí)才需要)
vim /etc/sysctl.conf #添加以下內(nèi)容
vm.max_map_count=262144
#執(zhí)行以下命令生效
sysctl -p
- 啟動(dòng)
./bin/elasticsearch -d -p pid #-d 指后臺(tái)運(yùn)行
