bootstrap check failure [1] of [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]【Docker启动ELK失败】更改系统vm.max_map_count设置值
[root@localhost /]# sysctl -w vm.max_map_count=262144
vm.max_map_count = 262144
# 再次查看
[root@localhost /]# sysctl -a | grep vm.max_map_count
vm.max_map_count = 262144
