[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 避免错误：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

sysctl -p

vi /etc/security/limits.conf
添加：
