安裝前準(zhǔn)備：
1. 安裝jdk1.8并配置環(huán)境變量
2. 資源調(diào)整
2.1 避免錯(cuò)誤：max number of threads [1024] for user [work] likely too low, increase to at least [2048]
[root@EPRI-DCLOUD-ES04 dcloud]# cat /etc/security/limits.d/90-nproc.conf
# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.
* soft nproc 2048
root soft nproc unlimited
2.2 避免錯(cuò)誤：max virtual memory areas vm.max_map_count [65530] likely too low, increase to at least [262144]
#vi /etc/sysctl.conf
增加改行配置：vm.max_map_count=262144
保存退出后揖曾，執(zhí)行：
sysctl -p
2.3 避免錯(cuò)誤：max file descriptors [4096] for elasticsearch process likely too low, increase to at least [65536]
vi /etc/security/limits.conf
添加：
* soft nproc 65536
* hard nproc 65536
* soft nofile 65536
* hard nofile 65536
