ERROR: [3] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65535]
[2]: max number of threads [3795] for user [esuser] is too low, increase to at least [4096]
[3]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
解决:
- 首先打开limits.conf文件:vim /etc/security/limits.conf
在end前贴入指令:
* soft nofile 65536
* hard nofile 131072
* soft nproc 2048
* hard nproc 4096
- 打开:vim /etc/sysctl.conf
贴入:
vm.max_map_count=262145
然后刷新sysctl.conf文件:sysctl -p
- 重新启动:./elasticsearch
