elasticsearch启动错误解决办法

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

解决：

[root@localhost config]# sysctl -a |grep vm.max
vm.max_map_count = 65530
[root@localhost config]# sysctl -w vm.max_map_count=262144
vm.max_map_count = 262144
[root@localhost config]# sysctl -a |grep vm.max
vm.max_map_count = 262144
