ERROR: [2] bootstrap checks failed

[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]

[2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]


启动报这个错误;

问题1 [1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]

修改/etc/security/limits.conf文件,添加或修改如下行: (请切换到root用户 然后强制修改文件)

*        hard    nofile           65536

*        soft    nofile           65536


问题2  [2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]


$ sudo sysctl -w vm.max_map_count=2621441

或者修改 /etc/sysctl.conf 文件,添加 “vm.max_map_count”设置 永久改变(sudo sysctl -p /etc/sysctl.conf生效)。

/sbin/sysctl -p 执行下 让/etc/sysctl.conf 立即生效

设置后,可以使用
