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

启动Elasticsearch报错：

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

意思是虚拟内存上限的值设置得太小了，至少要262144

临时方法：

sysctl -w vm.max_map_count=262144

永久方法：

vim /etc/sysctl.conf

添加一行：

vm.max_map_count=262144

更新配置

sysctl -p
